Try running restart.exe and choose recovery mode. That will also reset the Windows screen resolution settings. Then restart the driver and see if it sticks.

Well the first problem I see is the color format should not be YCbCr 4:2:0 at 8 bpc unless it's running in HDMI 1.4 mode instead of HDMI 2.0. Some TVs have an option that you have to enable to get HDMI 2.0 and deep color, but if CRU already shows an HDMI 2.0 data block, then I don't know.

I have managed to overclock it to 79 Hz successfully, but as soon as I cross this threshold, the monitor produces a tad flickering and very distorted and discoloured image (although the refresh rate seems to increase). I tried using the reduced LCD option too, but to no avail ... Does this mean that I've kinda hit the limit my display can handle? If not, could you please beacon me to what I should do to further push the frames?

Sometimes decreasing the blanking/totals will allow you to squeeze in a few more Hz, but laptop screens are usually not picky about timing parameters, so you might be hitting some other hardware limitation.

CRU is not meant for adding FreeSync to non-FreeSync displays. FreeSync could theoretically work with a laptop screen, but the driver would have to allow it.

Hey Toasty...

hmm at my TV i had already enabled Deep Color (it is called extended format at Sony)...

I use it for 3840x2160 60 Hz so HDMI 2.0 would be captable for 10 bpc and yCbCr420 with Limited dynamic range.
That is what i want, but i have just 8bpc here... funny thing, few days ago i had the 10 bpc option there.. so don't know

is ther any idea, how i can force 10 bpc in nvidia system control?

hmm... it looks like my Displayport 1.2 to HDMI Adapter is the problem...
if i connect the TV directly to the HDMI Output of my GTX1070 i got 8 bpc or 12 bpc also more color formats...
but i need it on the Display Port Output with an HDMI Adapter... otherwise i can't use my second TV in my multi-room setup.

not sure why, but few days ago, also with the adapter it worked... hmmm strange...

I have read the instructions several times and cannot retain the information to be able to ues the software. I have a Intel NUC dn2820FYK connetced to a Panasonic plasmat tv. The tv has no over scan settings so the screen is either too large or too small. Is there a video tutorial on how to use CRU? Youtube has some on overclocking monitors but none on setting custom resolutions. I know it can be done. When I first bought the NUC I found a app that let me set a custom resolution via a GUI. It had a box that represented my monitor and a red outline that you could drag to set the screen resolution. It worked fine. but I can't remember what it was called and can't follow your directions for CRU.
Overclocking is the same as setting custom resolutions. CRU doesn't deal with overscan. There should be an option in the Intel graphics control panel somewhere to compensate for overscan.

That is totally dependent on the which Intel driver you have installed. Using The Intel® Driver & Support Assistant installs the Intel HD Graphics Control Panel. The driver for my adapter installs a version of the control panel that does not support resizing of your screen. On my other PC the control panel has sliders to set the screen size. As I said I am not able to understand your directions for CRU. A resolution of 1880 X 1020 would result in my PC's display fitting my TV screen. Thank you for your reply.

Then add a detailed resolution with active set to 1880x1020. I don't know if that will work because the TV might just overscan that as well. If that's the case, try setting the scaling in the Intel control panel to center the resolution.

Hey guys quick question please. I have an old 2560x1440p korean monitor the Catleap from way back in 2012, yes the one that overclocks great. I just upgraded to the new Radeon 2020 Adrenaline today and when I was creating my new resolutions something occurred to me that I know would probably only be answered here.

If I use 1440p at 60Hz (native res) for everything in Windows 10 but launch games at 1080p, will the game be using the custom 1080p @ 100Hz resolution that I created using CRU? Or does the game just set its very own 1080p 60Hz resolution? And if so, is there a way to make games launch the custom 100Hz res when the game starts but automatically go back to 1440p 60Hz when the game quits? I'm only really interested in 100Hz when playing fast paced games.

Thanks

The Catleap can't display 1920x1080 @ 100 Hz directly, so you have to add 2560x1440 @ 100 Hz. The graphics driver will automatically add some common lower resolutions as scaled resolutions with the same refresh rate. If the game has its own resolution options, you can set the resolution and refresh rate directly, and it will not affect the desktop resolution. Otherwise, some games use the desktop refresh rate. In that case, you can use something like this to create custom shortcuts: http://www.bcheck.net/apps/reso.htm
