Custom Resolution Utility (CRU)

I have a 1920x1080 165Hz monitor but it has micro tearing on the desktop, browser, etc. I'm using CRU to add the same resolution and refresh rate and using Exact Reduced and I think the tearing is fixed but I'm wondering. Is there any risk in using Exact Reduced permanently? I don't quite understand what it is for and if I should use it for my native resolution at 165hz and so on. Thank you

There shouldn't be tearing on the desktop. That means there's either a problem with the graphics driver or the monitor is faulty. "Exact reduced" just reduces the time between lines and frames, which isn't important with digital displays, so as long as it displays correctly, there shouldn't be a problem, but you shouldn't have to do this.

I'm asking for a bit of guidance in advance of purchase. I'm going to pick up a Sony A95L 4K TV and I'd like to set it up with 21:9 resolution options like I have for my G1. It will be connecting to a Windows 11 PC running a 4090, so retaining its 120Hz refresh rate and HDR are critical.

Unfortunately, it's been so long I don't remember how I did all this and and I assume my profiles for my C1 won't be correct for the Sony. Is there a tutorial out there you'd recommend for correctly creating a given custom resolution (in my case, I'd like to create 3840x1600 and 3840x1646)? If not, would anyone be able to assist? Some of the finer points (like the Detailed resolution timing settings, parameters, and frequency settings as well as the extension block settings and how those vary from one make and model to another). The opening post in the thread was helpful but I still get a bit lost. I've searched long and wide for any A95L owners on earth who have already done this (so that I don't have to reinvent the wheel) but have come up empty (surprising given how long the TV has been on the market).

Stop thinking so hard and just add the resolution. Even easier, just use this: https://www.monitortests.com/forum/Threa...Editor-SRE

yes sir. lol

If I run into any issues, I know where to come.

Hello. I used cru to lower pixel clock and be able to do 240hz with a gtx670 (has a pixel clock cap) to use on my aoc 240hz monitor. I did an exact reduced resolution for that.
Now that i changed to a 4070s do i need to do anything? Is it still using the exact reduced? Should i reset-all.exe? Thanks.

CRU shows you if an override is saved for a monitor. If there's a "*" next to the active monitor in the list, that means an override is in effect. If it's next to an inactive monitor, that's the old monitor entry. Usually changing video cards creates a new monitor entry, so the old changes won't affect the new entry, but the old entry will still be there unless you used DDU to uninstall the graphics driver. If it's still there, you can delete the old entry in CRU using the "Delete" button at the top, or you can run reset-all.exe to reset everything.

Just wanted to update that this worked perfectly. All my preferred custom resolutions on my Sony TV with the full refresh rate options and HDR. Thank you again.

I'm trying to change the refresh rate on my 3 Dell U2415 monitors from 59.95Hz to 60Hz to sync up correctly with frame rate limiters and remove stutters that occur when these two aren't in sync.

So far I've tried the following:

- edit the existing Detailed Resolution in CRU to use a different refresh rate (tried 60, 55, and 50Hz)
- add a second Detailed Resolution in CRU with various resolutions and refresh rates
- remove all other resolutions and only leave the one Detailed Resolution with my desired resolution and 60, 55, and 50Hz refresh rates

Between all of the above items I rebooted and went into Windows 10 Settings -> System -> Display -> Advanced Display Settings to see if the resolution and/or refresh changes were available. When I realized that they were not available I reverted the changes, rebooted, and tried the next item.

After the last item I tried deleting the following registry key to see if I can get Windows to recreate the driver configuration related to the monitors

Code:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Con​​figuration

but they were recreated with the monitors default refresh rate of 59.95 and not the 60/55/50Hz that the EDIT override is asking for.

It seems that no matter what I try or do Windows 10 is just completely refusing to honor the EDID overrrides that the CRU utility is implementing.

Is this a known issue? In case it matters I'm running Windows 10 21H2 with a Nvidia RTX 4070 Super GPU with driver version 555.99 connected to 3 Dell U2415 monitors.

Thanks,
Harry

Is there any hope running 4K@120Hz (with a lower chroma) via HDMI 2.0b on an AMD GPU (5700XT) without the VRAM clock speed maxing out all the time? I can use the resolution fine by enabling 4:2:0 resolutions in the CTA data block.

If it matters, I'm using a 4k TV as a monitor (TCL C845).

That should not cause the memory clock to max out. Do you have any other displays connected? If not, that would be an AMD driver bug or limitation with the GPU.

No other displays and yes reading online its a GPU limitation. I was hoping I could get around with *just* the right timings.

I want to thank C.R.U. I have a Samsung LS22FS350FM monitor. I had a crash during the firmware update, I managed to recover the monitor(remove relating chip from board, put correct rom file in it and reinstall chip to board with soldering) but my computer started to see my monitor as an Acer or Asus 27 inch and only with 1024x768 and 800x600 resolutions. Samsung did not help me to go back to the previous firmware driver. The current firmware was not reinstalling because of the same version check. I tried everything, all the driver uninstallers, all the driver finders and installers, both for display adapters and monitors, nothing worked until I found C.R.U. Thank you very much.
