Thanks Gordy, although no rush mate as I think i'll be sticking with Component, then I can leave the PC plugged into the DVI.
And the Doom2 Res is 1360*768 - in the pic its stretched to widescreen, I forgot to press 4:3
Well if you do decide to give the VGA cable another go or perhaps get a DVI-I to DVI-D/VGA splitter* then here is something to try. Apparently it is better to let the TV do the scaling rather than the Xbox 360 itself as it's built in scaler is poor. I don't have a VGA cable myself so I cannot confirm this. But anyway...
Perform all these steps:-
Set Xbox 360 to output at 1280x720 (so that the TV does the scaling)
Set the DVI input to DTV mode (as opposed to PC mode)
And lastly center the picture on the TV (gives very slight bordering)
Here is a quote which describes the situation in more detail:
Here's the situation as I understand it, from reading here and Xbox-Scene.
-There is a difference between PC level VGA and Video level VGA (differences in colourspace and overscan).
-Most TV's assume PC level for the VGA input (thankfully the LG 26/32LX2R features an option to choose by using the DTV mode).
-The 360 outputs video-level VGA, causing a washed image on many PC monitors and LCD TV's which only accept PC level VGA.
What is needed is a dashboard update by MS to let the user select. They can do this, just like they added 1280x1024 support in an update.
The above may be a little speculatory I don't know. But basically by changing the LG to DTV mode and using a standard HDTV resolution (1280x720) on the 360 you can get around this. The difference in colours is apparent on most if not all LCD's, it is not specific to the LG. Thankfully the LG gives you the means to get around it.
*A cable is available which lets you split the DVI-I input into one DVI-D connector aswell as one VGA connector. That way you can have both your PC and your Xbox 360 connected to the DVI port at the same time should you wish. I have heard these cables are very good and completely lossless. Might be worth looking in to if you prefer the look over VGA.
