The panel is 16*10 15.4 Toshiba, Controller will work with LG, and Samsung.

ah. So it is stretching the 1080 image to 1200, am I right? Is there no way to do 1:1?

Nope, none of the MST controllers do 1:1, they have scale functions but it is always programmed funny.

The controller does a excellent job of scaling, you can see from the pictures.

oh, I know, it looks great. I'm just not sure about stretching an image, even though it's only a little bit. I have a Dell 2405FPW that I use for a TV and I can see the difference in 1080 and 1200 stretched. I want to have the 1920x1200, but hoping to find a good controller that displays 1:1.
Does the MST support HDCP?

I can see the streching too, but it is very minor and your eyes will get use to it.

The only controller I know that does 1:1 cost $425, This controller will be half the price of that.

I have not tested that yet (HDCP), but Im sure I does, will check with in the next couple days.

anyone have any news on the Kontron boards?

jhonzo thanks for the good work!

still no dvi inputs....why?? How can i connect a dvi source?
jhonzo, this controller is supposed to work fine also with sharp panel isn't it?
Which cable is needed to connect panel to controller, and where we can find it? Can you take a picture of the LVDS connector where the panel is supposed to be connected to?
Is this cable included in the package for the controller only or not?

thanks!

please forget my first question about dvi!!!! i just take a detailed look to the controller pic and i see on the left side, that hdmi connector!!!!!
Cna you reply me back to other quests?
thanks!

So if I plug a 360 elite in via hdmi it would be stretching the picture from 16:9 to 16:10 yes?

Has anyone tested the HDfury with the G2A controller?

johnzo,

I'm not sure what, if any, programming capabilities you have with this controller, but if you're able to program/modify the panel file(s) do you think it would be possible to "trick" the controller into only displaying the 1080 image over 1080 lines instead of doing the stretching? My knowledge about programming these controller cards is non-existent, it just seems like there would be some way to trick the controller card so that it doesn't stretch the image.

Yes, the image from a 360, or any other input would be stretched from 16x9 to 16x10. That's what I was asking about just earlier.
Last night it got me wondering about letterbox movies that are 2.31:1 and if they would be stretched too because that would look really F***ed up.

So... is this the same board as the current Mstar board Johnzo is testing?
http://www.neotecs.com/en/ProductDetail.asp?ID=65
The description is of course very cryptic but it does mention "Imaging point by point" so perhaps there is hope for getting the controller to do some kind of 1:1 mode...?

Has anyone been able to find any other HDCP WUXGA controllers that might work? (Other than the Kontron)

no it's not that.

hey. Anyone know if the controller boards that are in Dell 2405FPW or 2407WFP will work with smaller screens? The 2407 has HDCP support and are pretty cheap on eBay considering it's capabilities.

I've been wondering this myself. My logic is that WUXGA is WUXGA. The pixels are just bigger...

The different size panels might use different types of LCD technology. Also, more power might be needed to run the larger panels due to the need to crystallize/whatever it does to the liquid crystal.

Might be possible if they use the same method of data transmission. Single channel LVDS, is that the 'protocol'?

There is only one way to find out

well, I have a 2405 here and I don't mind taking it apart again. I've done it before so it's no big deal. I just don't know what to look for once it is open. I've had it all down right to the LCD. I know it's a BenQ controller board in there. If anyone knows what to look for and wants me to take it apart again and look for something specific let me know and I can take tonnes of pics all the way through.

BTW, I don't have have a PJ built or a panel to test it or I would. I was waiting for a new controller like the Kontron board or something that has HDCP support and 1:1 scaling.

What would be needed is any and all information on the controller board, and, more importantly, the LCD panel model number itself. Any pictures are a help also of course.
Then a comparison could be done with other LCD panel data sheets if available (not the monitor, the actual LCD)
The controller may well work fine with other LCD panels, but the only way to be certain is to check the specs on the panel it was installed to work with first, and then compare it with the data sheets of other LCD panels with the same resolution. They have to have the same native resolution, the same signaling same panel power specs (since a board made for a particular LCD will not likely have a jumper to change voltage to the panel like generic ones do)

I've run different panels off of one controller, but they all had the same specs, including resolution, and even the same cable pinout (although that can me modified if needed)

It's all a guess unless someone actually does the investigation.

well it does have the same resolution, 1920x1200, that's why I suggested it. I'll take it apart in a few minutes and take a bunch of pictures along the way, as well as write down anything I can find inside. I'm a hardware geek though, not software, so I wouldn't know anything about the programing or data sheets.

hey, guys, I just remembered, I have never posted pics on these forums, can someone tell me how? I'm taking apart the monitor and have it mostly done, taking pics along the way. I got a good pic of the controller board in it (BenQ) and the cables. I'll leave it apart for the night so if anyone wants me to look for something in particular I can.

okay, think I might have figured out the pics so I'm gonna give it a try.



should be able to see the serial number and stuff here.



the inputs that the 2405 has. The 2407 has HDMI as well.



all three controllers connected still. One on the right is the memory card reader and USB ports.

the three cards out. Should be able to see the controller info on it



other card where the power plugs in. I'm assuming that the cable off of the top is for the lightbox since that's where the cable ends up.



and these are the cables that go towards the LCD panel. It goes into another board before the cables go to the LCD itself. Let me know if you guys need that as well.

decided to keep going so I could put the monitor back together. It's my only TV for the moment. I have the new 2707 on the way (27" version of the 2407) and waiting on building my projector for my main TV.



The mini controller board that the other board goes into before the LCD. Two ribbons come off of this to the LCD.



The thicker ribbon



Thin one



serial and stuff on the bottom of the LCD

So can any of this help you guys out to see if we can use these as a controller for other panels?

First, I never would have expected you would take it all the way down to where you had the driver board and tab drivers flipped away from the LCD. Be very careful, as those flat connectors are very easy to damage where they are attached to the glass.

Unfortunately, the largest issue I see is that the LCD panel is using separate LVDS signal cables and power cables. The larger 30pin(looks like) cable going from the controller to the driver board carries the LVDS signaling, but to provide power, they have used a separate cable and connection. It is highly unlikely that anyone here would ever go to the effort to try and make that work with a smaller panel.
If the LVDS cable pinout was the same as for other smaller panels (at the same resolution), and other specs (timing etc) were the same, then it would likely drive another panel, but the power connection cable would have to be modified to provide power by adding pins to the LVDS cable. Not something for the average DIYer.

It appears that that is a Samsung LTM240M LCD panel. You can see it has a Samsung driver board (the board where the controller attaches to the panel), with a WiseView chip. WiseView is likely used to view certain file types directly from any on-board memory card slots. It looks like there may be some on that one board on the side. WiseView was apparently also used as just a marketing name for some panels that didn't actually have the memory card viewer capabilities at all.

I can't find any specs for the LCD panel itself to even find if any other panels have specs that match, in terms of LVDS, timings, resolution, etc.
Did the white sticker that is partly hidden in these pictures by the controller board have any further identifying numbers that can't be seen in these pictures (the highest on that sticker we can see is the top barcode)

I'm still surprised that you took it that far apart!

lol, don't be surprised that I took it apart. As I said, I'm a hardware geek. I'm in IT and I used to work at IBM here in Canada. When I first got these things the first thing I did was take one apart to see if I might be able to use the monitor for a DIY projector and what parts might be needed. So this was the second time I took it apart.
As for the controller, I understand what you mean with my last post and pics that show the mini controller. But what about the second post with pictures that show the contoller board with the inputs? The two cables coming from the top are the ones that go to the mini controller, and they are both from the same plug on the board. They are just split wires with two connectors on the other end (Y jack kinda thing).
Specs on the LCD are easy to find if you're just talking about resolution and timings. Just look up the Dell 2405fpw. WUXGA and 12ms response time. I'd still suggest the 2407fpw though. It's the one with the HDMI input and HDCP. Same resolution but 6ms response time. Does the different response times make a difference on the controller? I've seen such a wide difference in response times with the 15'4 panels that people have been using on here. Everything from 16ms to 50ms.

FYI, I had the monitor back together and hooked back up to my cable in about 15 minutes, works no problem.

oh, forgot to ask, what sticker were you asking about? Which post and pic number? I have all the pics in highres and I should be able to zoom in to see pretty well anything.

The specs I was talking about were the specs for the LCD panel, not the monitor as a whole.
I guess I should clarify. When I mention LCD panel, I am referring strictly to the LCD panel without external circuitry attached. Any company wishing to use a panel can have a controller designed for it, they just need the LCD panel datasheet to do it.

As far as the controller to panel connections, yes, they do come from the same connector on the controller side, but split to 2 different connectors, one for signaling, and one for power to the LCD panel. The Controller is the one with BenQ on it, the other board is not really considered a separate part from the LCD panel, it is the LVDS/RMDS/TMDS receiver circuitry. The controller has the LVDS/RMDS/TMDS transmitter on it (it's in the Genesis chip).

So, the issue is that without the specs for the panel, you could not be sure if the LVDS pin-out (if it is LVDS, it could be TMDS or RMDS signaling), panel voltage, syn frequencies, rush current, etc, etc.

As far as the sticker, I was referring to the white sticker partly under the controller directly below the Compnent and DVI inputs. The sticker has bar codes on it, and has the numbers: 0547 and 5M5K29815F. Not all of the sticker is visible in the pictures.
(or maybe all that is on it is)

On the other hand, again, the LCD panel appears to be a Samsung LTM240M1, I just don't have a datasheet on that to compare it with anything else. I do have a data sheet for an LTM240M2, and it is likely the same. When I get the time, I'll take a look at that.

Honestly, it could be as simple as making a new cable to attach from the controller to some other panels that have the same specs (size not being one of those specs!).

yea, that's what I was hoping, that it could be something as easy as getting a cable that would fit to a 15'4" panel.

White sticker:

0547 5m5k29815f L01

If there is anything else that I can find for you on the monitor just ask. It's easy to take apart and put back together and the pictures that I have are high res (I shrunk the ones I posted) so I can find a lot on them as well. I can even e-mail you the pics if that would help.
Only thing I'm curious about is how much difference the 2405 and the 2407 would be for this stuff. The 2407 is the one that we would want because of the HDMI and HDCP. My friend has a 2407 but I don't think he'll let me take it apart, lol.

As it turns out, after much searching, it appears that this BenQ controller for the 24" LCD wouldn't be of much help for a 15.4 or similar panel, as there are no panels it will support below 17" that are LVDS dual-channel, 8bit (16.7M true colors) and also having a resolution of 1920x1200.
At least I could find none in existence anywhere I searched.
The 15.4" 1920x1200 panels are all 6bit color: 262,144 colors, 16.2M with dithering, and as such would not work with this controller.

So, if that 24" panel ever dies, keep the controller, as it may be useful in a 17" - 27" 1920x1200 panel, with a different LVDS cable (or maybe not!).
Also, in reference to your original comment: "Anyone know if the controller boards that are in Dell 2405FPW or 2407WFP will work with smaller screens? The 2407 has HDCP support and are pretty cheap on eBay considering it's capabilities."
I guess "pretty cheap" is relative, as I checked and there was only 1 recently sold on eBay that went for less than $400. Most went more in the $450 range, not cheap to me!

On a similarly related note, for those who have broken a screen in preparing to assemble a projector, but continued on anyway, and obtained another monitor to replace the broken one: If you did not use an identical LCD panel or monitor, but still have the controller from the original panel, it may be useful to someone putting together a projector.
At least you might consider putting it in the trade section with any pertinent info you may have about what brand, model, etc of panel it was attached to. It could save someone a few dineros.

Like so:
Controller for Dell 150XXX. Was attached to a Samsung LXXXXXX
Has DVI, VGA inputs, OSD cable and panel, plus LVDS cable included.

ah, bummer. I was hoping that I might have found us an easy alternative to waiting for the Kontron boards. Do you think the Dell 2407fpw or any other 24" WUXGA will be the same? Even Acer has a really cheap one now.
As for my monitor I actually sold it a while ago. I had two. Sold one for $440 and the other is a trade for a new Nokia E90, I just haven't traded the one for the phone yet. Sold them because I have a blueray burner and can't watch any movies on those monitors. The new Dell 2707fpw should be here next week.

1) You shrunk the pictures? ;-)
2) Yes those connections are very different from the 15.4
3) Your controller has a genesis chip, which is a very nice scaler.
4) You could always build a 24" projector.
5) Thanks for clearing that up. I can now kill my ebay favorite search.

I am a programmer, I write cellphone firmware which includes LCD control.

Just thought I would mention that.

yea, I'm tempted to do a 24" PJ because of the stats like response times, HDCP/HDMI, etc. But I heard that the Kontron controller is suppose to have the HDCP/HDMI so I thought I'd wait to see what that was like. Still waiting, lol.
The other problem with the 24" PJ is the larger size fresnel lenses needed (which I do know where to buy already) and just the pure size of the box that would be needed. But making an upright one with a front surface mirror on the top to reflect the image to the screen. Coming close to going that way if the Kontron or other controllers take much longer.

Johnzo,

How much does it cost for a new controller + LCD ?

Could someone recommend a DVI-HDMI adapter ?

you cannot PJ a 24 cause threre's a too high risk of black corners.
also you would need a triplet really BIG!!!!

jhonzo pm me 250 usd for that controller...
and there no need for a dvi-hdmi adapter, it's just a cable with different connectors at the edges.

Yes, I was joking. Should have put a smilie after.

yep , but mac_angel seemed intrested!!!

johnzo1995 can you post a picture of remote control and keyboard provided wih KM9E89BTVL please.

Thank in advance.

I am interested, but those are fears about it. I know I'd have to use a 550 fresnel lense on both sides and a really bright bulb. I never thought about the size of the triplet. Either way, I don't have the money to try either one so I'm stuck until I do and maybe the Kontron boards will be available by the time I do.

I finished my testing with the MST KM9E89BTVL controller for the 15.4" Wuxga panel.

This one



HDCP is enabled and works perfectly !!!

1080p works perfectly over Component/Hdmi/Vga.
1080i also works perfectly over Component/Hdmi/Vga.
7200p also works perfectly over Component/Hdmi/Vga.
420p also works perfectly over Component/Hdmi/Vga.

Every Vga signal I sent at it , it handled perfectly, and 1920x1200 was perfect with excellent/sharp text.
1920x1080 from the computer to the Mst via the Hdmi cable had a bit of overscan, but less than I've seen on any other controller. With maybe 1/8 of the side icons hanging over the edge is all.

This really is a VERY NICE controller. It scales very well, I'd say just as good as the G2A controllers. No it does not have 1:1 scaling, but it does have zoom features that work nicely.

I highly recommend it.

the resolutions that you tried from the computer, were they all wide screen? or did you try a 4:3 as well. I'm curious about a resolution like 1600x1200 from a comp and if it's stretched out over the whole screen. Same with letterbox ratio movies (2.31:1)

so where do we buy it?

All resolutions are stretched. There is no 1:1 like I said.

But on a computer why would you run any other resolution. Just run it at 1920x1200.

Letterbox movies stay in letterbox format when played through a Dvd player or the Pc, but the entire resolution is stretched to 1920x1200.

But as I said, this controller has a very nice scaler that does a great job.

If you want a controller that does 1:1 just buy a G2A and the HdFury and a 15.4" panel and you will have it all. (For about $850).

lol, yea. Well, as I said before, I'm a gamer, and there are still a lot of games that don't support wide screen (especially EA ones). And definately can't afford the $850 at the moment either. I'm hoping the Kontron will be available by the time I do have money.

Well when he puts them up for sale, they will be at his store here:

Johnzo1995 Website

have you seen the available wuxga screens at this online seller for laptop screen replacement?
I have not yet read all the posts and found the discussion really interesting and would also want a solution that does not scale, something that would display 16:10 for a pc and 1080p 1:1 and preferably with hdcp. Have not seen a 17" wuxga screen but is there a controller with such a spec, hdcp 16:10 and 1080p with no scaling, that could run a 17" screen?

screentek's website

looks and sounds great I didn't notice this when I browsed the pages. Thanks for the invaluable information from jonjandran.

Jonjandran, I assume this was on your Sharp panel? So this panel will work with LG, Samsung, Toshiba, and Sharp 15.4" WUXGA?

No this was with a Samsung 15.4". it should work with all 15.4" Wuxga panels.
