I went over to my friend’s house to play our first guitar hero 3 battle for wii, mode only to start sucking immediately even though I play on expert and my friend plays on medium. “WTF?” I said. My friend was like “well I think you were sucking is all” but I thought I was going crazy. Was my wiimote malfunctioning?

Then I noticed the notes were coming down later than the music and started playing early and got a little better, but the lag was horrible. I asked him if he’d ever calibrated the game and he said no, so I calibrated it and the delay changed from 0 ms to a whopping 115 ms. Then I was able to play perfectly if I payed more attention to the music than the screen, but my friend had gotten used to playing before the notes hit so it messed him up to play on the beat. He tried calibrating again, but he hit the notes before the downbeat like he was used to playing, so the game recalibrated to 0 ms. We kept trying to recalibrate, but guitar hero must quantize the delay to either to 0 or to 115 because that’s what we kept getting. We compromised and set the calibration manually to 75 ms, which was manageable for both of us, but I had to play a little earlier than I was used to.

My friend has an LG HTDV. I’m not sure what model it is. I have an infocus SP5000 projector. When I play at home, there is 0 latency, though fast moving notes motion blur a little. His LG though has a very noticeable delay.

I had brought over donkey konga as well to show him the game, and plugged it in, but it was unplayable. I could compensate on the easy (monkey) songs if I played an eighth note ahead of the beat, but on the harder (gorilla) songs it was impossible. Unfortunately, donkey konga is an older game and there was no option to calibrate. My friend said it was fun and played it like he played guitar hero, but I feel bad for him, because he can’t play any of his music games on the beat with his TV. He says he thinks of it like conducting, where you make the motion ahead of the music, but as a drummer it makes me insane trying to play ahead of the notes.

After we were done playing games, we watched a movie, and I noticed that the movie sync was off with the sound as well. I didn’t bother mentioning it to him - he probably has never noticed and I didn’t want him to feel any worse about his expensive equipment.

I did find a website here about HTDV Lag - although after his tests, the author actually recommends a LG model. It must be a different one than my friend had.

Anyway, buyer beware, an HTDV may look great but you may not notice until after your warranty has expired that the display can have a huge lag. You’re not going crazy and that might be the reason you suck at guitar hero.

Leaving this as unsolved unless someone can tell me how to fix my friend’s LG HDTV.

-update-
Too bad you’re here probably because you’ve already bought a laggy HDTV and are searching for a solution.

I did find more info on AVS forum about the problem, which suggests to try to send signal to the HDTV that is in its native resolution so that it doesn’t have to rescale. I will ask my friend if he’s using the wii component cables and 480p which might help a little, but wii owners may be particularly out of luck as the wii does not produce full HD signal.

The article also suggests this device that will solve the problem, but at $2000 you’re better off selling your TV and buying a new one, unless your crazy TV cost way more than that.
