Hi, I recently bought a new Samsung Active Shutter 3D 200 HZ HDTV. But I have a big problem with Xbox 360 (couldn't try it with PS3 yet). I'm thinking that the cause is the TV, not the Xbox 360.
It doesn't matter if I play games or let the Xbox 360 sit there on the menu in idle mode, audio lag comes into play after about 2 hours. Yeah, at first everything is fine and after two hours, there is a slightly noticable and quite annoying delay in the audio. If I let it sit there like 4 hours, an half a second audio lag will occur and it will be very noticable. If I let it sit there on the menu (not playing games mind you, on the menu) for 8 hours, 1 second lag will occur and so on. I've managed to get it to lag it like 4 seconds so far.
When I switch the source from HDMI to some other source and then back to the HDMI, audio fixes itself.
I've tried three HDMI cables: two 1.3, one 1.4. No luck. I've tried the Xbox 360 on another TV and after 8 hours there was no audio lag. I've updated the firmware on my TV and I've updated my Xbox 360. Problem still occurs.
I've tried fiddling with service menu with no luck. It didn't get worse, it didn't get better.
So what causes this? What can be the possible explanation? Please enlighten me.
