First 1366*768 is 16:9, as is the TV as are most HDTVs if not all.
Second the monitor has and will do that resolotion and higher and has done for many years on multiple gpus, I can post a screen shot if you do not believe me, This TV has worked flawlessly.
I do not have two connections to the monitor, I only have one and even if I did I would swtich between the outputs on my tv to show the extended desktop. This would not cause a conflict. I only have two dvi ports and s video, no HDMI.
With my ati HD4670 i could have the DVI, HDMI and VGA plugged into the TV and windows would detect 3 displays, meaning if i switch the source on the TV i could view three separate desktops, so I fail to see how it could be issue.
Dont know what reviews your are reading but i bought this TV 4 and 1/2 years ago and it is still going strong, color reproduction is good is good. This TV can easily go up to 1080i and the reviews I have read after i bought it say that it is the best tv you could buy for that price at that time. I have already stated this but maybe i should say it again. This is a common problem with nvidia drivers
when connected to a HDTV and and nvidia refuse to acknowledge it, if you do a google search for blurry washed out colors with nivida drivers you will see what I mean hence why i have to input the EDID data myself, hence why i have this problem.
The monitor does not require drivers it is detected as plug and play. The EDID data is input directly into the nvidia drivers when they are extracted before you install them. You add in a line of code the overides nvidias default EDID data, then when you install them the display comes up correctly.
I think you may be under the impression I have not bought this display yet, but i am not going out to buy a monitor of equal size, the tv is 26 inch but it actually has a 26 inch viewable screen rather than 26 inch in total which i have seen and that cost. loads.
This will more than likely happen if plugged into another HDTV but will not happen on a montior.
I have also mentioned that I have used Nvidia drivers 197 up to the latest beta.
