I was long time NV user but recently I bought AMD Radeon HD7950 and I am in shock how good color correction works here

differences:
1. AMD have gamut correction feature and it's results are excellent. No need for calibration probe to correct gamut as it uses EDID information about native gamut and correct it to sRGB seamlessly in all aplications and games

2. AMD don't introduce banding when correcting gamma via cards LUT on both digital and analog connections where NV have ugly banding over DVI-D, HDMI and DP. Without such feature it is impossible to correct gamut outside few specialised software like PhotoShop

3. games don't override color correction like they do on GeForce cards. And if some rare game do it's much much easier to force custom gamma ramp without need for Color Clutch software. Color Profile Keeper and/or Powerstrip and we have custom gamma kept without fear of PunkBuster kicking you from multiplayer games from using Color Clutch hack

built in Radeon color correction works mirracles on my GDM-FW900. Without it colors were both over- and under-saturated, just wrong. Now with Radeon sweetness added to it everything looks perfect and I can say without any doubt: GDM-FW900 have the best image quality in the world :cool:

sticking with Nvidia for all those years was worst PC hardware decision I ever made :mad:
I had some monitors that had serious gamut and gamma issues and using those on NV cards was nightmare :mad:
I wish NV employers responsible for this drop dead and immediately after that burn in HELL for ethernity for their crappy products :mad: :mad:

Pictures please :p
 
I prefer to use a colorimeter and the OSD controls on my FW900 so everything is done through the hardware. The only thing I do in the display properties is ramp up the gamma (across all channels) so that I reach the 2.4 target (as measured with the colorimeter).

Using this approach means you're less dependent on video card software.
 
OP has a point, I don't generally bring it up in the wide gamut threads because everyone seems to be way more into nVidia.

I've got a Radeon 6870 running an HP ZR30w (wide gamut.) In the Catalyst Control under Color Temp there is a checkbox to "use extended display data (EDID)." With this checked, it effectively neutralizes the over-saturation due to wide gamut. It takes down the hot primary colors, but leaves the midrange stuff looking as it should. I don't know if this is the intended effect or just a by-product, but for practical purposes it appears to be remapping to sRGB. I've also got a ZR2740w, and it makes the two panels look very comparable. Without the EDID, I would consider the ZR30w essentially unusable.

cool info was looking to pickup a card soon. will keep this in mind.
 
Like many people on here, I bought high end Nvidia cards to help me reproduce the most accurate color possible as opposed to just dirty high frame rates.

But hey, at least I have some high quality TN panels to help make up for the color deficiencies in my Nvidia cards.

I'm also going to chime in here. I didn't know nvidia didn't have an equivalent, but that option makes the display look much better on my dell 3007wfp-hc's as well as my dell s2340's. Ut doesn't always work though. On dell 2209wa's, it makes the whole screen scream yellow. But that's probably an edid issue.
 
It does appear to be an AMD only feature at this point. I'm not sure if nVidia cards have the hardware to do it and don't or do not. It is also a feature only on 6800 and newer cards (at least to do it properly). this document has more info.

It'd be nice if GPUs got good at this and started offering configuration of it so monitors didn't have to. One of the reasons I have a pro monitor is to get the 3D LUT and get the ability to configure it as I wish. It'd be nice to have a GPU with the same capabilities.

So far, looks like only AMD does it, and then in a non-configurable (on or off) fashion. It's a start at least.

Then if we can just get AMD and nVidia to start doing 10-bit output on their consumer cards :p.

I don't t hink that's quite accurate, I've been using it since the 5870.
 
ATI have always been known for their image quality. So, I'm not surprised by some of the comments


But if you keep things default (no EDID or utilizing on-board image configurations), both are identical

So does this work on HDTVs over HDMI? It's probably the only thing I hate about my Panasonic, the banding in some Bluray anime is horrendous.

not necessarily

if game by itself set different gamma by default (thankfully not many do in recent years) then it will have banding too and it won't be captured on screenshots. Generally many older games render much darker and correct it by gamma so older games will look worse on Nvidia

another thing is gamma slider inside games. Some people use it and it will produce banding too

those artifacts won't be captured on screenshots !
 
NVIDIA is reported to be the chip used in NASA space craft as well as in luxury car navigation systems.
