DVI-HDMI takes away all of the YUV options (and audio) and leaves you with only RGB. The system trying to force you to use YUV (which also subsamples color to 4:2:0... check out black text on a red background) is Windows and the video driver being too clever for their own good, trying to force it to be a TV instead of a monitor. There are tricks you can use to fix it, like hacking the monitor .ini file in the Windows drivers folder to input your own EDID, but that's a huge pain and only works sometimes. Using DVI makes all the pain go away.

Of course, if you're using it as a TV and not a monitor you need very crisp text and most accurate color on, then it probably won't matter to you either way. Now the fact that it is a TV might mean that the overscan is affected on DVI, you'll have to look into disabling or mitigating that, and it might also mean that the TV can only input YUV and will convert from RGB to YUV and back even on DVI. TVs are a pain.
