Delays in DLP Televisions

I have a Saumsung HLP6163W and when I got it there was about a 250ms delay in when the signal is received and when it's displayed. A quarter-second doesn't sound like a big deal but video gaming was MISERABLE. The audio was synced accordingly which causes another problem: if you hook up yuor source to a receiver instead of the tv, the sound will come out a bit before the picture.

I called Samsung and bitched about it, and they sent a very competent technician over to look at it. He said it is a common problem with most models, and the only thing he could do is change the dithering rate. That actually worked, brought the delay down to about 1/10 sec. Marginally acceptable, not perfect.

Has anyone else encountered these problems? It blows my mind that these companies would make a tv with that kind of a delay. They definitely knew there was a big delay because they synced the audio output to be delayed the same amount. It doesn't have any effect on normal media entertainment (dvd, cable, etc.), just interactive activities like video gaming or maybe kareoke.

you could output the sound to a digital delay box and try it that way. wouldn't help with input-based things like video gaming but may provide an interim movie veiwing solution.

I assumed you were having this problem with ANY device that is input...

still bullshit, I still think if samsung can't fix it it's to be returned.

I also assumed you weren't doing anything to introduce latency into the process that doesn't need to be there, sounds like the tech would have covered that

no, i had my crappy 27" on standby as comparison. and i hooked up a portable dvd player w/ its own screen, pretty obvious delay.

they're dodging major marketing responsibility here. i know in their minds they are thinking "fuck them, 2% of the people that buy this shit play games and 1/4 will complain. heh, we can tell that minority to pound sand"

i would return it but the thing is so damn nice and i got a sweet deal on it. i'll just plan on using my warranty to bother them every time something goes wrong, like stumbling upon a crappy Friends rerun.

Tell them the money shot on your latest porn video wasn't clear enough, you couldn't tell WHAT was running down that girl's face at the end.

Do they still make DLP TVs? What's the advantage over an LCD?

Cheaper. I just saw a new 82 inch DLP advertised for 3k.

Yes, the newer DLP TVs with an LED light source are very good. Bright, nice picture, not too bad on the edges, although you definitely get a darker picture on the edge. Samsung makes some good ones.
