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