Custom Resolution Utility (CRU)

[Meruzzi]

Hello guys, I'm trying to remove 165Hz or put default 155Hz because for some reason when I use 165Hz look like a 75Hz, with 155Hz works fine. The problem is in CRU I can't creat any resolution above 120Hz, there's any way to use 155Hz as default or delete 165Hz?

Delete 165 Hz in the DisplayID extension block.

Can someone please help me out setting up custom res of 3840*2160@120hz please ?

I'm running an RTX 3070 and I can't get anything above 60hz in Windows / NVIDIA Control Panel on my new TV QLED Q80 2022 serie
Firmware is up to date..

I tried every tips I found from YouTube / Internet..

My HDMI cable is 2.1 certified, TV is supposed to run 4K 120HZ on all HDMI ports but from reading it looks like it's a bug from Samsung's side...

Where should I go on CRU ? I'm a novice
Thanks for your help

Return the TV and get something that works, or wait for a firmware update and hope they fix it.

It's probably an oversight or unfinished implementation. DisplayPort 2.1 shouldn't matter unless the monitor has a DisplayID, but only a few monitors like the Samsung Neo series use DisplayID.

Hi, i have a problem that started like months ago with CRU, I create a resolution with 75hz (my monitor is 60hz) and all goes good i can use it and that, no black screen,etc but after some restarts sometimes when i turn on my pc the resolution goes back to 60hz and if i launch a game it switches instantly to 75 hz or if i restart pc its on 75 again, i tried a different hdmi, timings,etc but nothing idk if someone had this problem, its very stressing changing the resolution sometimes when i turn on hte pc.[/font]

Neo G9 have 3 ports: 1xDP 1.4 and 2xHDMI 2.1, and it`s resolution 5120*1440.

If I connect my ProBook to Neo with DP-Type-C cable - all is works fine and resolution is 5120*1440. But in case when I use some dockstation (of course they all are supporting up to 8k resolution) the resolution became 3840*1080. The same dockstation with MacBook air on M1 give me the proper resolution - 5120*1440.

I think what problem is windows is incorrect monitor resolution detect via docstation. So I have been tried to use CRU to set custom resolution. But I can`t add it, the 5120 is marking red. I was trying to add dysplay id 1.3 in bottom block, clear all entries where, but I always see 5120 is red when I`m trying to add detailed resolution in upper block...

First, your screenshots show an EDID for a different monitor (Eizo EV2450). Second, your first screenshot shows you added it in the DisplayID 1.3 extension block, so why are you trying to add it again? Third, the monitor already defines the correct resolutions, so adding a custom resolution is pointless. There is a bandwidth limitation somewhere. Are you connecting more than one monitor to the docking station? The ProBook might not be able to handle the bandwidth for both monitors over a single DisplayPort connection.

1. Sorry, I`ve been posted previous message from my laptop without G9 near me. Here is two screenshot, the direct connection (via type-C -> HDMI 2.1 or type-C -> DisplayPort) - resolution is 5120*1440, another via dock connection and HDMI -HDMI, or DisplayPort - DisplayPort - resolution is 3840*1080.

2. Sorry, it`s seems what I didn`t understand how to configure the CRU. I thought, that I need to add resolution to DisplayID 1.3 extension block, and than add it to detailed resolution block. Is it wrong?

3. It`s no speed limitation via dock (Dell HD22Q), or cable. I`ve been tried to connect MacBook Air M1 to the same dock with the same cable, and all work fine.

4. I`ve been connected only one monitor (G9).

Is there any way to correct the off center output? I'm trying to get 30hz-ish, I got everything else cleared up, but not sure how to fix this last issue.

Hey guys,

Can someone please help me
I have a problem that I can't see the HD video, although the video is HD. I have the problem two days ago. Where is the problem from?

CRU has no control over that. That's entirely dependent on Windows and the graphics driver. The refresh rate should not change between boots unless there's a driver bug.

Why would you need to add it twice? You can't add 5120x1440 in the main window anyway as the first post explains.

There's some limitation somewhere, but it could be a graphics driver bug or some miscommunication between the laptop and the dock.

For DisplayPort, the Samsung Neo G9 uses DisplayID instead of EDID in 240 Hz mode, which could be triggering the problem with the dock. If you disable 240 Hz mode in the monitor's menus by setting it to 120 Hz, that might work around the problem.

For HDMI, 5120x1440 @ 60 Hz shouldn't be a problem unless it's limited to HDMI 1.x. There should be an HDMI data block and an HDMI 2.0 data block in a CTA-861 extension block as mentioned in the first post.
