Could this be related to the fact that the Surface Book has 2 GPUs? (A basic Intel GPU for tablet mode and the Nvidia GPU in the keyboard section for laptop mode.)

That shouldn't matter. EDID overrides work with laptops with switchable graphics, so there's some issue specific to the Surface Book 3. I don't see anything unusual in the EDID. The only significant difference is CRU doesn't include the range limits by default. Try enabling "Include if slot available" under range limits. Does that make a difference? If not, search the registry for "EDID_OVERRIDE" and delete any "CRU_" values. Does that make a difference?

I ran CRU (administrator), to add a new detailed resolution, modifying the frame rate, while copy-pasting everything else from my default profile. I then ran restart64.exe, but could not find the new profile in the Intel Graphics Control Panel. Is my computer incapable of overclocking its panel? Or am I doing something else wrong?

The driver seems to be ignoring the override. Try the alternative method.

Alternative method (.exe "Install EDID") not working with Intel Graphics 530, monitor Samsung B2230. Any alternative to reset/overwrite driver?

"Include if slot available" did not make any difference. I really don't know how to work with the registry. But, using regedit, I did a search for "EDID_OVERRIDE" and it didn't find anything.

->HOWEVER<- It looks like I've found a successful workaround.

Most of the time, I’m working with an external display. So, I tried setting this up with the external display connected, taking the laptop screen out of the equation. And it worked. Here are the steps:

-Close laptop.

-Connect external display and USB mouse/keyboard via USB-C Hub. Wake computer. It’s now working like a desktop - it’s only using the external display, since the laptop is closed.

-Using CRU, add the new detailed resolution. (I used the Manual timing).

-Restart computer. Do not open the laptop. Leave it connected only to external display until reboot is finished.

-After reboot, the custom resolution is available in Windows Settings, but ONLY when the external display is connected. After this, it’s OK open the laptop and use the laptop screen. The custom resolution is available and does work on the laptop screen, but ONLY if the external display is connected. That’s OK for my needs. If I ever need to use the custom resolution when I’m traveling, I have a 4K Headless adapter, which tricks the computer into thinking there is an external display connected.

ToastyX, I sincerely appreciate your support and responsiveness. Maybe this info will help future Surface Book 3 users.

Installed it, no big help. Still not showing my new profiles. Irony is my second monitor have all profiles that I created showing up, just this B2230 that nothing happens.

Using CRU disables freesync in my Radeon Software (says not supported)

Monitor: asus vg245h
HDMI (monitor only has HDMI, no displayport)
5700 XT latest drivers
Win10

I'm simply adding a new 1080p profile with 75hz, also tried changing the 60hz one to 75hz, did it via extension blocks as well.

After restarting the pc or using the restart64, radeon greys out the freesync. It says my freesync range is 40-75hz, so it should work, no?
It's annoying because vsync sets my FPS to 60 because of this. Using the custom resolution feature in Radeon doesn't fix this (despite making sure the display is set to 75hz). Making the change in CRU fixes it but then freesync is disabled.
I remember CRU working just fine with a year ago with my RX580 (and older drivers obviously but with AMD i don't really have the luxury of using older drivers given how broken they were for the 5700 XT)

Hi all,

I have a question if I damage my monitor/graphic card when I do following:

[Setup]
Monitor: AORUS CV27Q (2560x1440@165Hz, VA)
Cable: DisplayPort
GraphicCard: NVIDIA GeForce GTX 1060 6GB
OS: Win10

[Issue]
Since CV27Q is not gsync compatible, but provides FreeSync, the GTX 1060 allows G-sync. When I enable G-sync, the screen flickers at its brightest areas (where blb can be seen when everything would be black).

[CRU adjustments / Solution]
- Default Range (V rate) is 48-165 hz.
- Due to the typical issue of LFC, I tried to increase the range and so I changed the 48 to 40, 35, 30... but the entire screen started to show black screens very often.
When I changed 48 to 80 hz, the flicker is gone all of a sudden and the issue is fixed!

[My question]
Does this 80hz hurt/damage something, any problems?
(v rate 80-165, also I changed the extension block of "FreeSync range" to 80-165hz)

Thanks!

The monitor already defines 1920x1080 @ 75 Hz, so I don't understand how adding it again would make a difference. If vsync is not working correctly, that would be a driver bug. Are you sure it's set to 75 Hz in the Windows display settings? I don't know why editing is disabling FreeSync. CRU doesn't include the range limits by default, but that shouldn't be needed with HDMI FreeSync. Try using the "Edit..." button at the top and enable "Include if slot available" under range limits.

Apparently you can't have both 60 and 59,94 Hz custom resolutions with modern Adrenalin drivers using CRU (?), it only shows the 60 Hz one.

I had absolutely no problems doing this on a GTX 1060 before but now with a 6800XT the only way I can make Windows to show both "60" (60 Hz) and "59" (59,94 Hz) refreshes is to use the Adrenalin driver to make at least that custom 59,94 resolution, and those only work when GPU scaling is disabled .
