it depends - i've found that (on my TV at least, which is a 39" Insignia so it's some Best Buy no name brand) if i connect using HDMI it's garbage and hard to read because of the weird processing that is done, but if i connect using old-school analog VGA it looks WAY better.
HDMI - garbage, not worth it, you'll spend too much time either puking or trying to turn down the sharpening effects
VGA - great, simple, but you lose audio and it's actually an analog signal being sent, so perhaps less "authentic", but it's the only way to bypass the "hey, i'm a TV, let me process the crap out of your image"
so yeah. VGA is better. at least on Win8.1. i have no idea how Win7 would process things.
