Hi,
I finished my first projector and was using an n6 but wasn't real happy with the quality. I'm Looking to build another one and am trying to plan everything out. I'm want to use a samsung 730b that has dvi and vga inputs. I mainly use my xbox360 so i would want the best quality for this so should i use the dvi? Maybe something like this would work (http://www.trianglecables.com/dvi-hdtv200.html) but i haven't had any expierence with it.
thanks

That will not work. Is is designed for ATI cards to allow anolog YPbPr component outputs thru the DVI connector. (DVI-I) LCD monitors only support DVI-D.

This is not problem though, just simply use your VGA connector from the xbox360 to the LCD vga input.... you will get a great picture... then you can hook you PC to the DVI connector (if you also have a PC).

cheers,

I used this cable from microsoft which is awesome.

If you use this cable and you need to use the vga port to watch movies on too. You'll have to get some form of splitter/changer to go from one vga source to another unless you unhook one the hook up the other one.

If you want to use your component cables or other component cables and run them to your vga port then I suggest using the vdigi box. I also have this box and I use it as a switcher for my vga components. I also run gamecube on it using component cables.

thanks,
I have the vga cable but i don't like it because it runs in 4:3 which makes the games look stretched out. I was also wondering if this would work store.a2zcable.com/vcdvf.html it has a female component so i just take the standard component 360 cables and go into the female side and the dvi side goes into the monitor since it supports sync on green. Do you think that will work?
thanks for the help

The wording is a little confusing, but what this is saying is that it will take the DVI output of say a video card and convert it to component video out.

The key words are "component-video-capable DVI ports." If you don't know your monitor is component capible, I would not buy this cable.



I'm gonna get off on a little nerdy lecture here, so bear with me...

As with any new technology it's important to maintain a certain level of "backward compatability" with the old technology. In order to use DVI you must have a video card with DVI out and a monitor with DVI in. That means that when DVI was new manufacturers either had to force consumers to buy both a new video card (or a whole new computer) AND a new monitor, or implement both DVI and the old technology (VGA) at the same time. That is why it is so rare to find a monitor with a DVI port but no VGA port, but is so common for monitors to only have a VGA port. This is all well and good when you have a lot of space to work with (the back panel of a monitor), but doesn't work so well when you have very little space, such as the back panel of a video card. So what video card manufacturers did was invented a way (with magic I believe) to send EITHER an analog VGA signal OR a digital DVI signal with the same port. In order to use DVI you would just plug a DVI cable directly into the dual use port, but in order to use VGA you have to use an adapter. I'm pretty sure this adapter works without any microchips, it's merely a very short VGA cable with a plug that looks like a DVI plug.

Also, as you're probably aware, you can take an analog component video signal and convert it to an analog VGA signal (just so long as the monitor you plan to hook the VGA to has "sync on green" capibility). This conversion can be done without any processing or chips (AFAIK). I don't know if you can convert it easily in the other direction or not, but it's clear that the 2 analog signals (component and VGA) are very similar. The cable on that web page is pretty much 2 adapters in one, it's a DVI look-alike VGA plug with the output wires adapted into component video plugs.

So, long story short: even if it DID work you'd get the same signal as you would have through a VGA connection, but instead you'd be using an expensive cable...

One thing about converting (with pretty much anything): unless you're doing it to avoid some kind of interferance you can't get "better" quality by converting. You can't get the audio off a cassett tape and "convert" it into CD quality audio, all you'll get is "CD quality" crappy audio tape sound. If you're looking to get the best quality out of your 360 use the Microsoft branded VGA cable.

Sorry to make this post so long, but I feel explaining things greatly inproves both believability and understanding.

You can bet that the VGA cable is putting out the correct aspect ratio, if it looks funny on your monitor it's probably because your monitor is "scaling" the correctly formatted video to fill your screen. Unfortunately, since the monitor is doing this, it's pretty likely that you cannot fix it (without using an external "scaler box").
I can't help with scaler boxes (thank god right?), but there is lots of info on this forum about them, which one is better/cheaper/compatible/etc. I guess the Vdigi is actually a "transcoder," I don't know what this means exactly, but it's aparrently that means it's better than just a "scaler."

There's no magic,,, all the signals come out on one conector,, even VGA also

Transcoders convert component signals into VGA (and vise-versa). Whatever resolution you put into a transcoder comes out of the transcoder. All scaling will be done by the external device. (in our case the LCD montiors)

Scalers will actually change the resolution from the input to output. Inputs can be composite, s-video or component, and VGA (although this is typically just for a pass-through), and outputs can be the same types as the inputs. A scaler can change a 720x480 input (DVD resoltion) and output resoltuions like 1024x768 and 1280x1024 for displaying on LCD monitors.

Scalers are much more powerful than transcoders, but as such, the quality can vary. A good quality scaler will be much better for use with our LCD monitors than transcoders... the problem is they are typically very expensive.

hmmmmm.......
sorry to keep throwing out products but as far as video scalers go would a reciever with video up scaling work like this one? hwww.4electronicwarehouse.com/products/yamaha/rx-v2600.html
Also how would i be able to tell if my monitor component capible? I have a fact sheet here..fact sheet
Again thanks for the help
