I have a Panasonic Viera LCD I got around 1-2years before Circuit City went out of business, it runs 720p(though I've seen stuff report back 1080p) and at 60hz. It doesn't have a game mode or any other bullshit, it just gets the job done. Around a year ago or so I got a 46" Samsung LED tv, this one is 1080p and 120hz, it does have ways to enable or disable certain junk that corrects or adjusts and you can activate a game mode under certain conditions.
Clarity:
The Panasonic LCD will run my NES, SNES, and other pre-Gamecube era stuff with an almost emulator on a PC type sharpness. Colors are good, no soft edges, no bleed, nothing, just clean on good old RCA cables. Now the Samsung is the opposite of this as the imagery is like if someone had an old late 80s color TV and someone was daisy chaining like 3-4 RF cables back to back. There's blur to all of it, really soft rounded off edges, no real color bleed, it's just 'muddy' as people like to prank on N64 for over it's AA features when used badly.
Speed:
Panasonic wins here too and oddly enough a really good test for this outside of old systems which is really screwy would be Super Mario Allstars 25th Anniv package for the Wii. The game on there runs 1:1 speed, there's no input lag, no weirdness, everything dials in and does as you want as you do it. The Samsung though wow, not a chance, which is odd as other stuff like even New SMB Wii run fine, but the old emulator SMAS runs with significant input lag to where it's almost like a 1/4 second delay or damn near something like that as I just end up dead on it time and again.
I didn't even realize it at first when I bought the game when it was released, got pissed at it for being lazy shitty Nintendo corner cutting. I only realized it was the stupid TV when I got one again super cheap a few months ago or so but only got to it in early November, and wow, again like my SNES cart, it ran at 1:1 speed on the Panasonic which I never even thought to try it on.
Now through all that rambling of evidence, keep this in mind and hell I may be wrong but it fits. Once I found that Wii emulated SNES game running right it blew me away so I did some research. I found out that supposedly 60hz tv's are the best to be using for in particular classic pre-3D or 1st gen(N64 era) titles because they run at the right response time and look crisper(mind you the crispness probably varies by tv model.) My readings said that 120 or even 240hz tvs basically resample the video it is fed so for a 120hz it's got double lag having to run the image twice and 4x over on 240 which is why they have these lame bandaid 'game mode' fixes and other on/off switches for junk in the settings.
I'd suggest finding something that runs at 60hz from a local shop that has returns, take it home, pop your NES, SNES, etc into it and see how it rolls. If I'm and the other stuff I read up is right you'll be happy.
