Not being a gamer, I just guess I don't understand that. There can be no lag longer than 17 ms, because the screen and each pixel is refreshed at that rate, and when a pixel is reilluminated it flushes what was there before. The only way a set can refresh faster than 17 ms is to use a faster refresh rate than video has in the first place, and even 240 Hz can't refresh as fast as the LCD pixels do, because modern LCDs refresh typically at 4 ms or quicker anyway, so there could be no overlap.
It must have more to do with the duty cycle. An LCD screen is always full on, and what illuminates the pixel stays at the same brightness until it is rescanned. That could make the normal human persistence of vision make it appear to have lag I guess. That does not happen with plasmas because they are only illuminated for part of the duty cycle (they blank between scans). And on CRTs the illuminated pixel fades between scans, so its duty cycle is more like a sawtooth wave.
I know folks who are hyper-sensitive to flicker (the same folks who see rainbows on DLP, probably) and they love LCDs and 120Hz because 60Hz flicker on a non-LCD gives them headaches.
But maybe your complaint has more to do with screen lag rather than LCD refresh times, as you mentioned "input lag". By that are you speaking of the latency or time delay between what the game inputs to the display and the screen image actually changing? Because I can see how that would be completely irritating to gamers. Instant response is imperative.
All sets have that issue, but this one maybe more than others. Of course if the audio is delayed to match, which is usually done in the set, it doesn't matter for passive viewing because that cancels out any time lag between video and audio.
So I guess gamers may have an entirely different set of priorities for a set than viewers do.
