Custom Resolution Utility (CRU)

Hi everyone!

Apologies if this is a stupid question, but does this tool actually modify the display? I have a B9 and want to get the new xbox when it is out which will have freesync.

If I enable freesync with this tool, will that enable it for other devices plugged in to the TV, not just the pc? Thanks!

Need help from experienced people here.
Year or so I have used CRU to modify edid info to force idle VRAM clocks down (at default they stayed always max).
But recently i have encoutered weird and annoying GPU behavior. When monitor in stand-by state, after timeout (20 min), i am unable to wake it up. Just heard one sound (just as when new device connected, not two as it should) and that's all. The monitor just showing black screen with horizontal bars sometimes flicker.
The only way one may wake it up is when i change timings such way, that MCLK is back to max (1750Mhz)
If there's a way to aviod choosing from either working monitor power saver function or 200Mhz idle MCLK clock ?
Thanks!

That shouldn't happen unless there's a driver bug.

May be you're right. Tested in linux (ubuntu 18.04) - memclk 1750. I set modeline w/xrandr according to window's preset / CRU. After display switched to a new mode, the memclk is back to normal 200Mh. Monitor power saving (i.e sleep/resume) works in linux regardless of the current resolution (X.org 1.20) . What's left is to find the culprit. Besides driver it may well be the last 2004 update's wdm.
By the way, your LCD standard preset is not enough in my case to lower idle mem clock and memory overclocking has no impact to it either. Increasing VBI from 52 to 60 (2560x1440x75) did the job.

I seem to get close to resolving that bug. I uninstalled "old Radeon Settings" application and find out that:

1. If no monitoring apps running in the background - monitor do resume from sleep.
2. If MSI AB have launched - fail to resume.
3. (the funny one) If GPU-Z is running in the background, right after the monitor goes to sleep, it repeatedly tries to wake up, but failed to. On the other hand, keyboard/mouse events do successfully resume it. It looks as if gpu-z sensors polling triggers this.
(I will update later when finally test it with 2020 Adrenalin).

UPDATE: tested with latest dirver files and settings app (all from adrenalin 20.8.1 package)
- fresh boot : resume works
- launched MSI AB : failed to resume (resumed with monitor off/on then)
- killed MSI AB : works again
So MSI AB somehow broke monitor power saving functionality.

Hello. I am experiencing an issue where Windows 10/nVidia believe my Denon receiver has a native resolution of 1080p. Because of this, some games will refuse to output above 1080p, even if I my resolution set to 4k in Windows and nVidia Control Panel.

I've been experimenting with CRU to see if I can fix this, and I have been able to correct the issue by adding 4k as one of detailed resolutions and then deleting all the "TV resolutions" in the extension block except for 4k. Unfortunately, doing this also causes me to lose sound output entirely. Looking at the INF I'm using, it appears that the sound information is indeed there, but it somehow isn't registering:

CE audio data (formats supported)
LPCM 8-channel, 16/20/24 bit depths at 32/44/48/88/96/176/192 kHz
DTS 6-channel, 1536k max. bit rate at 44/48/88/96 kHz
AC-3 6-channel, 640k max. bit rate at 32/44/48 kHz
DTS-HD 8-channel, 16/20 bit depths at 44/48/88/96/176/192 kHz
DD+ 8-channel, 16/20 bit depths at 44/48 kHz
DVD-A 8-channel, 16/20 bit depths at 44/48/88/96/176/192 kHz
SACD 6-channel at 44 kHz
DTS-HD 8-channel, 16-bit at 44/48/88/96/176/192 kHz

CE speaker allocation data
Channel configuration.... 7.1
Front left/right......... Yes
Front LFE................ Yes
Front center............. Yes
Rear left/right.......... Yes
Rear center.............. Yes
Front left/right center.. No
Rear left/right center... Yes
Rear LFE................. No

Everything in my signal chain support 4k60, so I don't think there's an issue there.

Make sure the 4K detailed resolution using "LCD standard" timing. The pixel clock should be 594 MHz. Also, make sure there is one slot left for the monitor name. I remember NVIDIA's driver having a bug that would disable audio if the monitor name wasn't included.

The name slot trick worked. Thanks!

Hi there!

Could I get some help with this software? I've followed the instructions as closely as possible and I still cannot change (via settings and display adapter properties) nor see the custom resolutions anywhere. The monitor I want to change the resolution of is the same as my main monitor but is hooked up as follows (main monitor using USB to DVI-D), Computer>USB Dock>USB to HDMI adapter (drivers installed, I think the issue is here)>HDMI to HDMI cable>HDMI to DVI-D adapter>Monitor. Right now as of writing this message, the monitor I want to change the res of is flickering because it is running on 800 by 600 at 60 Hz (which I think is unsupported by the monitor itself, highest res on monitor is 1920 by 1080). Thanks in advance for all the help!

- Jai

NOTE: when changing the resolution settings in CRU, I exported my main monitor's (same monitor, different adapters) setting (.bin) and imported them into the monitor I am trying to change.

The driver for USB graphics (usually DisplayLink) doesn't support EDID overrides. I don't know if they provide a way to add custom resolutions.

That kinda sucks because I just re-set up my computer hoping for a 3 monitor setup. If you come across a way to help stop the flickering or change the resolution please let me know. Thanks!

QUICK EDIT: I realized it was not plugged into a USB 3.0 hub and instead a USB 2.0 so i swapped it and the resolution was fixed. Now my only issue is flickering and cutting out of the monitor (I think it has to do with a message I keep getting about the adapter not being compatible with my GPU but I have the drivers installed so I don't know why I keep getting the message). I can post a video if requested. Thanks for the more help!
