I do not know what parameters the TV needs to have to do this (I only have one to try with), but you might be able to improve the detail in dark areas and contrast.
Specifically for an Asus GTX 660 Ti and Sony Bravia KDL-32W5500, there is a setting in the NVIDIA control panel under "Display"->"Adjust desktop colour settings": "Dynamic range". Set it to 0-255 instead of 16-235.
It works for both Windows 7 and Windows 8.1, but that option is not available on my other display, which is an old low-cost 1080p Asus monitor. The same option may be available in Intel or AMD GPU drivers, and will certainly be available with some other TVs and Nvidia-powered display cards.
I was surprised by how much better my NASA desktop background images now look, even though it's only an LCD panel rather than plasma.
