GPU color quality

[Nik Balor]

Is there any difference in color quality between Nvidia and AMD cards? because switching to AMD gave me better quality image, or is it just the how Nvidia GPUs handles the HDMI signal ?!!

You can tune color accuracy in their control apps, so there's only difference in default settings, not actual ability to deliver accurate colors.

[Hiya!]

As the sir mentioned above you could change the color accuracy or temperature through their apps.

But if u want better with any GPU buy IPS panel monitor.

Hello, I don't know why you see color differences with the two, I have had similar situations where I connected different cards to the same monitor but I have never spotted the difference. Color accuracy is mainly related to monitor's quality. It is adjustable by the built-in tools that comes with your monitor and good monitors comes calibrated out of the box from the factory. You can manually fine calibrate them afterwards but it is a tricky and expensive process. Make sure both card's software are set to default color settings and technically there should't be any difference. Tho I might be wrong and it would be interesting if someone can provide more knowledge about it.

i just read an article that talks about how poorly Nvidia GPUs handle the HDMI signal ! will it be the same with the display port ?! read this pcmonitors article.

Interesting read. Now that I think of it, it is a while I do not use hdmi.

yeah maybe that's why you don't notice the color difference

Did you try to follow the solutions proposed by the articles? In my case Display Port automatically sets itself to full dynamic range of rgb space.

Is it really the graphics card though? Sometimes it's the monitor.

My own monitor is when using HDMI is trashy because of the it's post-processing, older models have this, but is still very good on VGA.

Well you know how it goes:

 

Seriously though colour quality depends on the display not the graphics card, tuning it is a must if you'll work with it professionally.

This is normally true but there are some exceptions. The article posted before by the author says sometimes the GPU classifies the monitor as a TV, limiting the color range displayed and therefore color quality. It is indeed a GPU issue but easily fixable.

no i haven't tried it actually , in that case maybe i'll just change the HDMI and use display port instead

that's exactly what im talking about , sometimes the GPU classifies the monitor as a TV

what monitor are you using ?

[bobhumplick]

usually its because the gpu screws up and tries to treat the monitor as a tv and sets dynamic range to limited instead of full.  you can change it in nvidia control panel under resolution.  you have to scroll down and change dynamic color range from limtied to full.  if you have washed out colors then you are using limited range settings on a full range display and if you have the opposite and its overly black in dark areas then you are using full color range on a limited display.  any other difference is just down to color profile and can be changed.  people say its because of texture compression but both companies use delta compression that is lossless and some poeople say its because that amd gaming cards support 10 bit color while for nvbidia you have to have a quadro but games dont support 10 bit color and not many apps do either so it really makes no difference (HDR excepted)

but some games really benefit from the 10-bit color, and wouldn't it affect and lower the fps if i changed the color range from limited to full?

no games benefit from 10 bit color.  an app or a game has to be written to take advantage of 10 bit color.  limited and full color are something different.  they are not the same thing as 10 bit or 8 bit.  in limited color the first 4-5 colors shades are cut off and the last 4-5 color shades.  thats out of 256 or 64000 i dont remember.  i think its 256 or so.  if your display supports full then you need to use full.  if it supports limited you need to use limited.  but some tvs need full and some limited.  a very small number of monitors use limited but most are full.  there is an easy way to tell as i said above.  

 

"if you have washed out colors then you are using limited range settings on a full range display and if you have the opposite and its overly black in dark areas then you are using full color range on a limited display.  any other difference is just down to color profile and can be changed."

 

as far as 10 bit color that is for video editing (like in adobe premiere).  NO GAME SUPPORTS 10 BIT COLOR PERIOD!!

The statement that no games support 10 bit is incorrect...for Forza if you run HDR at 8 bit vs 10 bit, there is a dramatic difference in the baning on the car bodies.  8 bit, almost looks like stripes or CAD, 10 bit, smooth as silk
