No, but the brightness and contrast settings in the NVIDIA control panel can produce a similar effect.

The thing about brightness and contrast is they change all colors. I'm looking for a way to brighten only black colors if possible.

Any ideas?

thanks

But the dynamic range option affects all colors. Something like 60% brightness and 30% contrast comes close to what you want.

Got it, thank you for your insight and advice.

Hello, I'm on iMac 5k Radeon R9 M395 on bootcamp and couldn't make CRU to work.
clicking restart64.exe will reboot the system and detailed resolution I added is gone as if untouched. after restart.exe new framerate doesn't been added.
Although the monitor's native resolution is 5k (5120 x 2880), it is written that its Active Signal Resolution is 2560 x 2880, so is the resolution written on the CRU. and typing 5120 x 2880 would make it the text red.

Also I'm using radeon driver version 18.40.20
I want to overclock the framerate slightly since I saw someone overclock their MBP to 119hz.
what should i do and which resolution should i type on the CRU?

Sorry if this has been answered, also thank you for keeping this thread running

You should see two active monitors in the monitor list. You have to add 2560x2880 to both. I'm not sure if that display can handle higher refresh rates though. That resolution already pushes the limits of DisplayPort, so there might not be much room for higher refresh rates.

Hello,
I have three monitors connected to a gpu (2DP, 1 HDMI), If I extend the freesync range of one monitor, the scrolling for the HDMI monitor stutters. Is there anything that I can do about this? All of my monitors are at 75hz.

Thanks,

Make sure the timing parameters and FreeSync range match on all three monitors.

Hi.

I set my monitor 60Hz at 75Hz, it supports the frequency but the color depth dropped from 8 to 6.

Is there a way to solve?

This happens with DisplayPort when you exceed the pixel clock limit for 8 bpc.
