Okay first off, taking pictures of a tv is a bad idea (: I snapped about 15 but none looked decent.
But, good news. I was prepping my pc for my new CPU that arrives today and loaded up the new Nvidia drivers which came out a couple days ago. There is now an option on the control panel, under Video & Television, to resize your desktop. Which does exactly what you wanted I set my TV to some stupid resolution 2500 and change (you can force reso's now too) and was able to shrink up the desktop so you could see the windows bar and icons perfectly. The games look really nice on it as well.
Just another selling point too, the GTX+ models have HDMI pass through audio, I'm trying to get EVGA to let me buy a 2 pin to 4 pin SPDIF cable they have for it. I bought mine a while back and didn't come with the standard GTX's back then.
