Custom Resolution Utility (CRU)

[Fear_The_Duck09]

Hey guys. First of all sry for my bad english. I think i have a problem. Bought a new aoc c27g1 monitor, it had some freesync flicker, so i downloaded cru, and modified the low range to 25 instead of 48,worked perfectly for a while. I have 2hdmi port, when the system wasn't edited with cru, the first on was able to do only 120hz,now both can do 144 somehow. The freesync flickering is back, and i cant fix it with lowering or increesing the mhz limits. I think cru messed up something for me, and i wanna compleatle reset everithing, and start over, but when i using reset all, nothing really happening, still both my ports doing 144hz,and still have BAD flickering,and now i cant go lower then 46hz instead of 25,because i get black screens when my monitor hit 45hz or below. How can i reset this thing guys?

If you have a problem with a new monitor, you don't try to fix it with software. You return it. CRU didn't mess up anything. Running reset-all.exe and rebooting resets everything. Your problems have nothing to do with CRU.

The new driver (441.12) doesn't appear to have fixed the issue that I had with 441.08.

This time, I'd already used CRU to make the necessary modifications to my display's EDID (adding a custom resolution of 4K@66Hz and deleting all 4096x2160 resolutions). I also made sure to restart Windows to apply the override, instead of running restart64.exe, as that's what seemed to trigger the odd behavior before.

Only after clicking on "Enable settings for the selected display model" and hitting "Apply", under the G-Sync tab on NVCP, is that my system restarted automatically and went into an infinite reboot loop again.

Even though my TV is now "G-Sync Compatible", it still shows up as not validated on NVCP, requiring manual enabling of that setting. It's been like that for the previous two drivers with support for G-Sync: 441.08 and 440.52 (beta). However, the infinite reboot loop issue only happened on drivers 441.08 and 441.12.

Not sure what's causing the problem. It may have something to do with VRR and the TV's "Instant Game Response" mode, which activated even before enabling that specific setting and immediately after installing the new driver (G-Sync was enabled by default for full screen mode).

Any guesses? Everything worked fine in Safe Mode, but a simple reset of the EDID (using reset-all.exe) didn't solve the issue today, and I was forced to reinstall the driver (always using DDU). I've yet to make any EDID modifications since the reinstall, as I'm afraid of triggering the infinite reboot loop once more.

Yeah, broken driver. Have you submitted feedback? https://forms.gle/kJ9Bqcaicvjb82SdA

Today i upgraded my gpu to rtx 2080 super from gtx 1080 (driver version 441.12)

and i noticed after using CRU for setting my BenQ EX3203R's minimum V-rate from 24 to 48 (needs to be done for gsync/adaptive sync to work) that the card wont clock down in idle anymore if the second screen is connected.

On my gtx 1080 i had my second screen connected via DVI running at 60hz and my main display via DP at 120hz to be able to clock down in idle and i had no issue with that.

Funny enough when i let it stay on 24-144 it even clocks down now on 144hz with the second display connected which it never did with older gpus.

The new card doesnt come with dvi anymore so i tried DP and HDMI just to be sure but no chance.

the notes say "The video card will not reduce clock speeds when idle if the vertical blanking/total is too low. Horizontal values can still be reduced if necessary."
but im not sure what to make of that since i raised the value from 24hz to 48hz? Maybe its not even connected i really dont know :<


I need my idle clocks back please help. What kind of numbergames can i play with cru to be able to run my main display at least at 120hz +gsync compatible and my second display at 60hz? Hell id even take the second display below that, its just there to play tvshows and movies.

Simply changing the minimum adaptive sync range shouldn't affect clocking down. That would be a driver bug. The video card can't clock down the memory with multiple monitors if the blanking periods aren't synchronized, so I have no idea how idle worked on the 1080. They have to be running at the same refresh rate with the same horizontal/vertical totals, or if one monitor is G-SYNC and the other is not, the G-SYNC monitor has to always synchronize with the other monitor at 60 Hz.

I just got my new Razer Blade Stealth late 2019 (GTX 1650 model) and I figured I would give CRU a wack.
To be fair, this is my first time using CRU but I have overclocked monitors in the past including the one on my MSI GT83VR.

I also want to say what an awesome community here! Sorry to hop on board when just when I have issues but I fear an intel driver limitation.

This is a 10th gen ice lake model with the 1065g7 eDP (hwinfo) and every time I make ANY change in CRU, it results in a black screen. Maybe I'm literally doing it wrong? I add any new resolution, even the same one that's listed by copying the settings of the default, then hitting okay, restart.exe and bam. Black screen every time. I have turned off all of the power options in the intel settings but every time I get a black screen. I have to clear settings and restart to get it back. I don't even get to the option where it lets me select the new refresh rate. I tried looking up and down the web today but I just can't find anything.

Any ideas?
Thanks!

Can you try the alternative method for Intel GPUs? Laptops usually have switchable graphics, and the alternative method should work with newer Intel GPUs as well.

Is there a chance that you could add physical monitor dimensions? It's displayed as Image Size and Maximum Image Size in MonitorInfoView.

According to the EDID specs the bytes of interests are 21, 22 in Basic display parameters and bytes 12, 13, 14 in Detailed Timing Descriptor. When I tried to edit it in AW EDID Editor and then import and apply in CRU those values get reverted back to defaults.

That depends. What do you need to set the image size for?

I thought about adding the screen size to the display properties, but the screen size can contain an aspect ratio instead with odd calculations, so that complicates the implementation a bit. If you select "Import complete EDID" when importing, it will import this information.

For detailed resolutions, my main concern is people won't know what to put in for the image size when adding or editing a resolution, and I haven't seen anything actually use this information, so CRU just puts in the resolution divided by four. I'm reluctant to add this unless I can find a way without cluttering the interface.
