Actually, it's 'better quality' in a few-ways...(refresh/brightness/contrast...although inferior to the Philips/15.4?).
I got pricing for several kinds of controllers and panels from him...perhaps not the one(s) you're referring to here? I hope you'll 'rep' the guy stateside, so we don't need to fool-around with WesternUnion fees, etc., and we have 'clearer info' (not to be critical of Carpow...his English is 'first-rate'/excellent compared to my Mandarin!). I also like that you 'pre-test' as you do -- a helluva deal, considering expenses if damaged-goods due shipping from China [scan back a few...and see my pic related to that!<g>]
Try, also, to discover all the other things he might find for us there (polar-bears [NOT panda's!!!]/reflectors/pre-cons and certainly, better-quality controllers...like the one linked-to above!).

Unfortunately, this is a controller chip and not an actual controller solution. By itself, it is off no use. We would have to develop a board design and firmware around it, which is certainly beyond my abilities and/or desires to do. I believe it is the basis for many of the board designs out there, however.

Mmmmmmmmmmmmmmmm...!
Faroudja!

G2A controllers use the Genesis / Faroudja chips.

Its amazing how HDCP has been around for a while now yet nobody is incorporating newer chips in their controllers. Cant we put together a list of people who want these controllers and then tell a company to build new controllers for us.

<g>
We're an unfortunately tiny-market for that...
Most of these available/after-market 'controllers' used for what are meant to be laptop-lcd's were developed for custom-applications in kiosk's, RV/automotive built-ins, LVDS, and varied-other 'oddball'/niche markets (most of them much-larger than our purposes). For that kind of 'business interest', most consumers were focused on lesser-def/cheaper panels, and not really geared towards 'home theater' -- so it is not high on manufacturers "Do Lists" to pay-out licensing-fees for HDCP-compliance (and this sort of thing is not-really a 'priority' to the folks involved with boutique-fabbing in China...any more than their dvd-player mini-industry looks toward complying with Macrovision, or other 'priorities' for copyright-holders in other-countries). Not to say that there isn't such a HDCP-controller 'in wild' (although I'm having no-luck locating one), but they will likely be both expensive, and 'down the road' re: availability.
Right now, I'd be happy to locate/import any multi-input jobbie with similar feature-sets/quality, for those stuck in the sub-150. crowd (these 350.+ boards, while reasonable quality, seem to be as 'stepped-on' re: mark-up as Mexican-heroin...<g>).
I assumed the G2A had fine-chipset/features...but balk at the pricepoint (when lesser-boards, such as those with the RTD2533V+RTD2613 can be 'had' for much-less, and 'reasonably' serve our scant-needs).
[Then again, I'm notorious as a 'cheapskate'...<g>]

HapHazard...I'm having a hard time locating much info on that chipset you specified the RTD2533V the only info i can find on it is from realtek at this link-
http://152.104.125.41/products/productsVie...&ProdID=131

On that page it states that chipset has a max res of WXGA+/SXGA.I got in contact with carpow but I want to be sure about the controler specs before I go ahead and order.Do you have any links with other specs for that chipset?

hmmm.
Carpow sent me those chipset-identifiers for 'controller for Sharp/Samsung wuxga/15.4 panels, along with pricing info for it and the LTN154u1 (with mention/acknowledgement that the panel was 1920*1200). I just 'assumed' that, feature-set aside (such as sync-on-green/flipping/etc.) it would at-minimum, support the panel fully via component/svga-inputs. 'Maybe' he misinformed re: chipsets, or maybe-not...?
Since Johnzo has waded-into this importation-project, I'll leave it to him to 'clarify'...[someone needs to get much-fuller info/specs on this stuff, and inquire as to other-options].
I am also looking for other/larger commercial contacts in/near ShenZhen and HongKong...and will share what I find later/soon (I'm seeking better-quality, if 'pricier', controllers -- with HDCP, if such exist).
Johnzo is ordering test-panel/board in 15.4 now, so we'll soon have his 'review'...?

Some newz...apparently it does display 1080P/1920*1200...as confirmed by Carpow, and an independent buyer of the board in question.
I believe that Carpow also has access to controllers with the FLI5921-chipset/Genesis...hoping for spec's/availability/price on one of those 'soonest' (for a 10.6/1280*768 -- a 5962 will be required for 15.4/wuxga, but he may have a shot at those, also -- more later).
edit: Nope, no FLI available...

I'm going to be on a boat until the 17th of Jan. If anyone comes up with a controller soultion for my 15.4" WUXGA 1920x1200 Samsung LTN154U1-L01 that isn't too pricey put me in on a group buy or use me as the guinnea pig and order it for me. I'll be happy to paypal money to someone and of course compensate them for the extra work involved in getting it to me.

So the controllers that come with the 10.6" panel also work with the samsung 15.4 wuxga panels??

Yes-and-no...<g>
Carpow (for-one) offers at-least two controller-boards I know of...each with different RTD-chipsets (one sent with the 10.6's, that displays only up-to 1280, and the other for 15.4's, now-confirmed up-to 1920). But, in his test-beds illustrated at his Chinese-forum for led-lamping, I noticed the controller he used himself was Genesis-chipsetted... In his ShenZhen province, home to many of these controller-makers, he can probably 'lay hands on' any great variety of boards for us...at differing 'pricepoints', of course. But getting 'details/options' from him regards all he sells (or 'could' sell) is an 'onerous task'...<g>
Also, many controller-boards (flashed, or otherwise) 'work' with a variety of different 2-channel panels. The 'trick' is pairing them for 'fullest features possible'...so the boards shipped with 10.6's may 'work' on 15.4's, but not at wuxga-resolution.
Clear? [as 'mud', I suspect...<g>]
The different boards all vary by way of available inputs, also...with the better-ones offering the 'big-3'.

The G2A220 came in today.

Tested it with a Sharp L..02 and L..12. Both work well, though I haven't tested too much. No time to check the compnent in or any other features. Glad to have a backup screen if something goes wrong. I'll probably use the 12 to start.

If anyone has anything special for me to test before I start stripping the LCD I can check it out.

Looking forward to HD...one day.

Edit: There is a Picture-in-Picture mode and a Side-by-Side (PAP) mode. Connected my upscaling DVD player with component and S-Video cables and there is a huge difference in the two results. I'll post an image later (left the camera at the studio). The S-Video is brighter and lower contrast, The component the opposite. The component connection looks much sharper to me. I'll get an HDMI to DVI adapter and post pics of the difference. I twill be interesting to see how they compare.

If size doesn't matter, would you rather use a big set of fresnel lenses and a 24 inch Dell or the new 24 inch Gateway ? I mean that way you could play with newest technology, such as 1000:1 contrast ratio and 5 ms response time.

But some people say the smaller dot pitch of a WUXGA laptop screen will produce better pictures. What is your opinion ? Thanks.

I was playing with the Picture-in-Picture as well, but only with the bare panel and a small source of light. I was playing the spiderman dvd on a dvd player using component and or s-video. I couldn't get the deep dark reds to show up. It wasn't colorful as it could be. Playing the dvd on the PC with a vga connection, I could get more accurate deep reds as it should be.

There would be several problems using such a large LCD.

First it would be hard to find fresnels large enough. Second there isn't a triplet large enough to "see" a 24" Lcd. The Pro Triplet is only good for a 19".

I've been using a W02 panel for test purposes and the PJ is dialed-in. However the panel is "test" because of a permanent horizontal white line (don't know how it happened).

Getting ready to unwrap a brand new W12 for "production" purposes and will attempt an AG strip by soaking it with acetone/distilled water solution. Is the 1/3 acetone, 2/3 water proportion still recommended? For both the front AG and 2nd rear reflective layer? Thx

not quite on the same topic - but the G2A210 has been replaced by the G2A220 - just ordered mine.

I saw fresnel lens of 20" x 36", I think that will cover the whole 24" Widescreen, would it ?

Also, I thought the light beam after the second fresnel lens will be concentrated into a spot . So you would have to move the Pro lens a bit further away. Do I make any sense here ?

DVI adapter/HDCP question....

I'm still testing the G2A220 with the backlight in (I've stripped both 02 and 12 panels and they are still good).

I bought an HDMI to DVI adapter and connected my sony upscaling DVD player to the controller. The other connections work fine (composite,component,and s-video), but the DVI line only flashes dark grey and black.

As I understand, the dvd player will only send 1080i throught the hdmi cable, so my question is this:

Am I seeing HDCP in action?

My next test is to reconnect the player to my Sony HDTV (LCD wall mount) with the DVI adapter and find out if it receives the signal clean. I think that will tell me for sure, since the TV is a month old and surely has HDCP.

The wife is watching Duke basketball, so it will have to be later (no tearing her from the TV), but I thought it was a question worth posing.

Yep that's HDCP in action. What kind of Dvd player is it ?

It's a relatively inexpensive single DVD player. Sony DVP-NS75H. I think it was around $100.

Would love to know a way around the problem, though I suppose I could use my laptop to drive the pj.

I found a link somewhere here to a site about hacks for some dvd players, but the site only had a simple note about region issues as it pertained to this player. I considered seeking an HDCP stripper since I am getting an HD DVR for the house and I feel sure that will also be inoperable with the controller.

little bit of a bummer.

Harvey.. the FOV "Field Of View" of the pro lens will not alow you to use larger than a 19" widescreen lcd.

Does anyone know if any of the camera lenses could be used as projection lens ?

No , a camera lens doesn't have the FOV to see a large Lcd. It is only able to see about a 1.5" area.

And this is a 15.4" Wuxga question thread. Only questions about the 15.4" or it's controllers, etc. Please keep on topic everyone

I was the one who brought the idea of the Kontron controller to this thread. Yes, it's been on my mind all the time, building one using 15.4". But I am also looking for alternatives to the "15.4" WUXGA" . I'd say it's pretty on topic.

We aim for new technology, high res, fast response, color reproduction, contrast ratio, HDCP, HDMI ... so far, the 15.4" WUXGA is a bit lacking.

True enough...
The 10.6-projects, based on the Samsung 106W2's, (and, really, any laptop 'solution') are stinkers re: refresh and color-count, etc. -- compared to monitor approaches.
OTOH, some of these controllers offer inputs/options not found on most monitors (albeit at increased-expense). And, for 720P-playback of existing/std. dvd-libraries (from upconverting-player or HTPC), the smaller 15.4 and especially 10.6 sizing brings many advantages for lamping, optics, space/heat/energy-savings 'to table'.
Toss-up...
One 'alternative' to consider is efforts to reduce the relatively high-expense of laptop/controller combos (we so-far have found good-deals re: controllers/panels from Carpow/Johnzo...although the 2-chip wuxga/RTD controller is feature/quality-scant, if 'cheap'...and panel-savings are relatively 'minor'). At least there is 'progress'.
With luck, a FLI5962 chipset controller will be found 'cheap'...and paired with a LPhilips (16ms), not a bad-combo. And soon, small 720P-capable 10.6" & smaller will make for good projects out of 'undersized-PJ's'.
As for HDCP...it'll be awhile before any relatively-cheap Chinese option actually 'pays the price' for this "free trade era" foolishness/compliance. And, by then, we will likely have 'easy work-arounds'...
But, unless huger LED-lamping becomes 'practical', there seem too-many drawbacks to >19"-options for PJ's...they are clunky-enough already (compared to commercial), and present 'issues' with optics/parts-expense un-met by any scant-improvement in PQ/display -- it's not like they offer really-small pixels [like the .18 on the 10.6's] to offset 'issues', nor are 24's 'cheap'.
One alternative-approach as yet 'unexplored' might be finding a reasonable-cost 17-19" wuxga-monitor (someday?), then combining that with a separate/reasonable controller (for inputs, primarily)? Or watch for the really-small and/or better-spec'd laptop-panels to emerge? And, who knows, maybe LED's and/or other 'exotic'-lamping will offer options?
Right now, I can't imagine a 24"-based PJ being 'desirable/cost-effective' -- compared to what-else we can do...(but, if someone does build-it ..."we will come" [to the Plog, at-least!<g>]).

Just saw over in this thread that member Tobias Claren can get the Kontron controller over in Germany and that a model featuring HDCP is coming in the middle of next year.

Seems like we'll have to wait a while before HDCP is conveniently available to the DIY market Buying a separate HDCP stripper in addition to the controller doesn't seem cost-effective in my opinion...

Alternatives...

Just want to throw this out for the htpc guys out there - has anybody had a look at some of the laptops that use seperate graphics cards rather than onboard? I was kicking around a while back and found a few of them out there. this card is for a dell inspiron 8500 and will drive a 15.4 wuxga, I believe:

DELL Inspiron 8500, 8600, Latitude D800, Precision M60 64mb nVidia GeForce4 4200 video card with cooling fan
Part Number: 2Y068

http://www.laptopking.com/partpicture_LK.a...category=boards

If the interface is a standard AGP or whatever with a mini interface or custom pinout, possible to build an adapter to put it in a full size PC and use it to drive the panel? I don't have any spec sheets on this item. Anybody know? It might be nice to get into a wuxga panel controller for $135. I don't have time or money to go down this road right now, but someone out there might have the parts laying around to experiment with. Just a thought.

Not to interrupt... returning to aforementioned G2A220 info... for the record..

Pics of input differences I mentioned a page back (post #313).

First a shot of the board. with all cables attached including fairly useless speakers...


The following pictures were shot with the exact same aperature and shutter speed, to compare. Also worth noting that these are just shot with the backlight.

Shot of Side-by-Side (part of PIP feature on the card):
This is showing two inputs from the same paused DVD player at the same moment. Not pasted together like the triple-shot below.
Left side is Component input. Right Side S-Video.


Three shots full screen.
Top-Component Input
Middle-VGA (loaded on computer with WinDVD)
Bottom - S-Video


Obviously some H:W ratio difference between the DVD player and computer. Haven't looked into that yet. Just looking at color and contrast.

No real questions, I just thought it was postworthy for anyone looking at this controller.

Any 15.4" WUXGA panels that are easier to get the front AG off than the Sharp. Or, better yet, any that have the high-gloss front finish? I just buggered the polarizer on my new Sharp W12.

Check out GSX's Plog. He found a toshiba and had no problems...

GSX posts 130-133

Sorry to hear-that...but,
since you did, can you volunteer to fully 'clean down to glass' on both sides, and try it with matched/high-contrast polarizers each-side?
[I'd like to hear/see the result...with any/all of the _many_ AG/tac/diffusing-layers really 'off', and new polars NOT selected on the basis of intended-performance with back-lighting...or has anyone, yet?]

Don't know squat about polar selection, ordering, mounting, and cost. Would volunteer to do if someone does the homework and cost is under $50.

Costs for 'known' high-contrast polars at the two-sources used in LL to-date are 'high' (although I'm exploring an import-source that is 'more reasonable' by-far). I'll soon have a couple-extra polars, but sized for a 10.6-panel (larger, presumably, can be had later) if you'd care to try with those (free, other than return-postage to MI -- I've no likely-candidates for my own 'testing')? [One advantage of 'small' being ability, in your case/box, to try both 45 & 90-degree alignment...and check for 'differences'...]
Also, elkin had some-luck with only applying full-sized polar at rear of panel, and a small/'rotatable'-scrap/piece at-or-in his triplet (and many have smaller-pieces that could be 'donated to cause' -- but results vary for split/unsplit).
Considering your 'alternatives'...you may want to 'bite' (unless you are in-hurry to replace the panel?)?
BTW, to do this 'properly' (if other notions/findings elsewhere in LL are 'correct') you'd need to be willing to completely clean-off both sides of your panel...so that matching polar-specs/types are on front and rear...
Interested?
[If not...will you be offering that panel for sale? And/or is anyone else--with such a polar-damaged 15.4"? I'm also interested in checking-out one of those 'reasonable' 2-chip controllers mentioned previously...]
'Mounting', however, is a less-perfected procedure. Some just 'hang' it near panel/fresnel(s)...although mounting it 'tight', somehow and to some-surface, would seem best as far as lumens-loss...?

OK, i just got around to testing setup 3. the results were the same as setup 2 only 1080i works this time.

I even tried unplugging the G2A 130 between tests as jonjandran suggested. Can anyone else with a 360 test this, GSX? Or hopefully sculporM can test his G2A220 if he can get his hands on a 360.

Something to ponder, computer VGA signals use 0-255 levels for RGB, video component signals use 16-236. That could be the cause of the problem.

Can anyone tell me how to be sure that the displayed resolution on a G2A220 controller is actualy 720/or1080. Because my DTV STB is HDCP compliant but i doubt this G2A220 card is and i have it hooked up on the HDMI out on the STB and DVI in on the G2A220 and it works no problem

Hi, I'm totaly new here and this will be my first post on the forum.
At the 3Dlens.com you can order polarizing sheets at affordable price. The 17 inch LCD Polarizer (Product No: #P17) provides 36% maximum transparency (in pair) however the the lcd panel itself could absorb some light also. It's a bit pricey you wont fit to the $50 limit with shipping but you can choose a cheaper one for the experiment. (I'm not sure if they have the polarizer in the same size in both directions but may worth to ask them.)
I hope it helps a bit.

They are one of the two-sources indicated/known for these high-contrast goodies. My hope is that the ones I ordered are equal/near those spec's (but much-cheaper, eliminating 'middleman'). 'Quality' remains for testing to prove (so, too, the much cheaper wuxga-controllers from the DIY-community/re-sellers in China), but price for polar-pairs there is relatively-minor...as for fresnels. [I've a sampling coming for playing with, to see how they compare]

Be sure you select 1:1 pixel mapping in the OSD of the controller. If it is in 720 mode it will not fill the entire screen, it will only use 1280x720 of the 1920x1200 pixels. In 1080 mode, it will fill the entire width, with just some slight "black bars" on the top and bottom. (ie. only using 1920x1080 of the 1920x1200 pixels). In 480p mode (which is what HDCP is supposed to do if the display is not HDCP compliant) you should have a real small area of 640x480 being used.

Hope this helps.

cheers,

Sorry, I'm a noob on the wuxga scene. G2A220? I see this is a controller board. Which lcd's can this be used with?? Also, where do I obtain one of these bad boys!? I googled it, and the only results were Lumenlab posts! Ha!

Thanks guys. Sorry for the noobish interuption.

Follow the link in the first post of this thread (Here)

enjoy.

i looked in the original link thread and did not see comentary on model G2A220 specifically...

which of the two stated controllers is the G2A220 most similar to?

It's the newer version of the G2A210.

I don't know what the differences are between the two though.

Well HDCP must have gotten dissabled somehow,I set the G2A to 1:1 and cycled threw 480i 480p 720p and 1080i on my DTV STB and all display corectly.I just watched 2 periods of the NHL All Star game in HD...All i can say is WOW!!!!! This setup was worth every penny.

FYI I can Verify that the LG Phillips LP154WU1 lcd works with the G2A220 Controller kit

To share help for those buying the 220:

Freefall wrote me asking about the inverter connection (if you are testing before stripping) and I figured I'd share a better picture of the board setup so those who buy it won't rely on the bad photocopy. I know I posted one earlier, but hopefully this one is a little clearer. I also linked the main board shot to an 8mp (3260x2440) shot in case those who bought one want to print it out.


The Main board shot with link to huge:


A bit blurry detail of what worked on my board for the inverter plug:

Most HDCP remains 'uninitiated'...
