"Lag" during play

The tv will show correctly in 720p mode. Cable box and PS3 must be set to display in 720p or the green tint will remain. For the PS3 I return it to 1080p when I am about to play a game, blu-rays and dvd's can only play in 720p.

I have sound on video 2, and when on a static channel but not on the usual channel 3 which is TV. Just stoppen working one day and cant figure it out... Please help!

It sucks to see ALLLLLLL these solutions, when I have the solution. Turn off DEEP COLOR in the video settings. It will immediately stop. If it doesn't, then you don't have the typical snow/flickering problem.

did you uncheek the other options when choseing 1080p or it might be your receiver because you have to set that to make the picture quality as much as the ps3

I had the same issue. I think you have to reset your PS3. I don't remember how I fixed it but I did find the anwser in the PS3 user manual "Trouble Shooting".

2 questions:
Are you using HDMI cable?
Have you tried your ps3 in any other HDTV?

Heres why I ask you this. PS3 has some compatibility issues with some TVs (or Tvs have it with ps3....that is controversial xD) so if you happen to be so unlucky to have bought an HDTV which ps3 has issues with, you`ll have a problem (as was my case)

In my case whenever I switch resolutions or enter a game the HDTV starts flashing between the ps3 screen and some blank screen with dots. I have to remove the hdmi cable and connect it again and it solves. :D

So please answer my 2 questions in order to discard some possibilities.

If your playing with lag on your new HD LCD your at a competitive disadvantage! Everything you see happens seconds later than your opponent who has his/her settings right.
The fix:
1. Connect your PS3 using HDMI Input 2.
2. SELECT or RENAME the HDMI Input to PC. Already pointed out, but this does not make the majority of tv's run in PC mode.
3. On the PS3 start-up menu go to Settings---> Display ---->
Choose HDMI ----> DO NOT choose AUTOMATIC ----> SELECT CUSTOM ----->
4. Now, Select all the Resolution options EXCEPT 720p. This will force your games into 1080p mode. What it will also do is drop any game that doesn't have 1080i/p support into 480. Games like Burnout Paradise, Vegas 2, Heavenly Sword, NHL 08 and more will be dropped into SD (480) rather than HD. Your picture will be terrible. 720p is standard gaming resolution currently, 1080i/p is not.
5. Save and complete the display setup.
6. Turn off the PS3. Turn off the TV.
7. Turn on the TV. Turn on the PS3.
8. Complete! (Lag eliminated). Please spread this around!

*The key to eliminating ALL LAG is modern LCD's need to be in PC MODE (NOT GAME MODE) On many tv's, PC mode requires you to use a VGA or DVI connector. You'll either need to buy an HDMI adapter or an HDMI to VGA / DVI cable if that's the case.
and the Source MUST BE IN 1080p so that the TV can use it's NATIVE RESOLUTION.* Please, check your tv's native resolution. If you have a plasma that only does 720p, your native resolution is probably 720p. You do not need to follow these steps, it will only make things worse. If your tv's native resolution is 720p, obviously you want to keep your display settings at 720p on your PS3. If your native resolution is 1080i, you shouldn't go selecting 1080p. If your native resolution is 1080p on your TV, you need to be aware that removing 720p as an option will force many games into 480.

Keep these things in mind and remember that the steps above are far from a cure all solution. .

Same happened to my ps3 one week from new , took it back the the shop and got a refund.

i also had the same problem with my Samsung 1080P.its seems there is a "handshake"issue between the ps3 and the tv.restarting the system helped solve my problem.also insert the cables once again.

a DVI Connection does not transmit sound, so you will need a seperate audio cable. Have you changed the settings in the ps3 and your tv's input to HD signal or 720 DPI, do not choose 1080i or 1080P as DVI does not support those high settings.
