OK now im going to try to make this as simple as i can. I will firs tell you that i have had similar problem with my winxp box the problem is that the hdmi tv when in 1280x720 (720p) i am missing cutting off like 1/2 inch of the image . Almost like if it would be zoomed in to much . Now the early driver for the win32 box was OK . Since i upgraded the drivers on my winxp box i have had issues (cutting off) i also notice a new option called (resize desktop) and that fixed the problem also notice that the final resolution is 1176x664 instead of 1280x720. The old win drivers did not have that option nether the problem.

So my question is how can i fix this under linux there are no desktoop resize option in the gui driver setting for nvidia . i am unsure if a custom resolution of 1176x664 will fix the issue as i think it may have to do with the H and V sync. Is there a way i can mod my config file to help ?

Thanks

Hi,
Your problem may be that your total horizontal resolution may not fit within the video card's maximum display area. Use 'xvinfo' to list the video card's attributes. Look for the 'maximum XvImage size:' line. For my 8500 Nvidia card, the max size is 2046 x 2046, so 2046 is my max horizontal resolution. (I only have one monitor, at 1900x1200) You didn't mention the res of the second monitor, but I assume it is 1280 horizontal as well. That means your card must support at least 1280+1280=2560 max horizontal resolution. If xvinfo reports max XvImage as less than 2560x2560, the blank edge is outside the max display size. I suspect the max size will be 2456x2456 (as 1280 + 1176 = 2456).

If this is the case, I don't know if there is anything that can be done to change the max display. I have never had any luck changing the size or aspect of the max display area. I believe it is determined by the hardware itself, but I could be wrong.

You can also use the xrandr program (enter: 'man xrandr' for details) to adjust your video outputs on the fly, maybe it will help get a display setup you are satisfied with.
