When i have the resolution set at 1024*768 i get a clear picture that fits perfectly in my TV screen.
When i have it set a 720p the picture quality is poor (very pixelated) and the desktop is about 4cms too big on every side of the screen. The taskbar dissappears along with any icons on the sides or top of the screen.
When i have it set at 1080i the desktop shrinks to a square in the middle of the screen and the picture quality is horrible.
If i have it set at any resolution other than the ones listed on the back i get a 'no signal' message.
I also have an issue where to get the picture to fit the screen properly when watching a movie i have to watch it in 4:3... So basically its like the TV is naturally 1024*768 and 4:3.
I've been in the display settings and nvidia settings and nothing much works.
I found a post online elsewhere that said the 720p claim was a furffy with this TV and that made sense considering my problem.
Is it possible i have an earlier model (or just a model with different firmware) than yourself and that is the problem?
Any help would be much appreciated. The picture quality at 1024*768 is still good... But would like it if i could have it set at 720p and watch everything at 16:9 with it filling the screen.
I have an ATI graphics card hooked up via HDMI and I use two screen resolutions. For watching recorded video from DTV I run Media Player Classic at 1280x720 (720p). All files that have less than 1280x720 resolution, I use ffdshow to resize and sharpen the picture to 1280x720. It works reasonably well but despite trying a zillion different settings and recommendations from forums like this one, the result is nowhere near as good as my Oppo DVD player. Files that are 720p or 1080i look outstanding on the TV with MPC.
As you have mentioned, at 1280x720 there is overscan and you loose most of the taskbar and edge of the picture, so for most other HTPC usage I use a custom resolution of 1200x672. This allows me to see the whole windows desktop on the screen. Setting up custom resolutions with the supplied Control Center software is easy with ATI 4800 series graphics cards but I have no idea what is involved with NVidia's cards.
LG recommends 1024x768 over the VGA connection and the picture is acceptable but the aspect ratio is incorrect and the picture is not as sharp as native 1280x720.
