So I have a VT25 Panny plasma and I calibrated it on my ps3 with DVE and when it comes to brightness set via DVE it looks perfect for Blu Ray and other videos. However games are washed out at that brightness but the DVE test pattern says it's right, but games that have their own calibration setting and test pattern for brightness such as Uncharted 2 and FIFA 12 is saying it is way to bright based on their test patterns

To combat this I have to change my TVs HDMI black level from light to dark and those test patterns for brightness in the games are perfect but then Blurays and the DVE test pattern are way to dark and blacks are crushed.

Anyone know what might be up?

These are the setting for PS3 that seem to be recommended.
Video Settings

BD Internet: "Allow"
BD/DVD Cinema Conversion: "Automatic"
BD/DVD Upscaler: "Normal"
BD/DVD Video Output Format (HDMI): "Y Pb/Cb Pr/Cr" for TVs, "RGB" for PC Monitors
BD 1080p 24Hz Output: "Automatic"
BD/DVD Dynamic Range Control: "Off"
BD/DVD Audio Output Format (HDMI): "Linear PCM"
BD/DVD Audio Output Format (Optical Digital): "Bitstream"

Display Settings

RGB Full Range (HDMI): "Limited"
Y Pb/Cb Pr/Cr Super-White (HDMI): "On"

Sound Settings

Audio Output: Varies/Automatic

And do go with that.

No, the same settings and calibration SHOULD work for both.

Any variance you experience would be due to a game developer lacking the correct methodology for "mastering" their game correctly.

I'll throw a wrench into the situation.

I always do 2 calibrations.

One for Video
One for Games

Hdmi limited should only be used on video.

Hdmi full range for games

Video games are "Mastered" aka rendered with 0-255 RGB.

So you can have the PS3 compress the black to 16 and white to 235 using HDMI limited, but I prefer not.

While this is true it adds significant complexity to systems that don't necessarily benefit from the increased complexity.

Any issues with games will come from inconsistent gamma, which is an issue regardless of nominal levels. So you don't side step any problems there. It's possible that you might notice some posterization from the range compression, but I bet if I had two identical model tvs setup side by side one playing a game full range and the other compressed to 16-235, you wouldn't fare any better at guessing the correct one than flipping a coin.

If you use RGB Limited, you're losing values from 0-15, as the lowest value output over the HDMI connection is 16. However, using Full doesn't really improve shadow detail. The only values you get out are 0,1,9,20,33,43,57,67 in blue and 0,1,8,11,12,15 in red, and most values in green. So you're getting the values pushed up, but if you have dark red or blue areas, they will be very blocky and not gradients, and most dark areas could easily have a tint to them based on that data.

So while this does compress full range RGB down to limited video range, it does it in a fairly clunky method that isn't smooth across all the colors and can lead to posterization and tinting of images as well.
