Added 80 Hz with LCD Standard (resulting in 325.53 PClock)

Are you able to add something between 330-340 pixel clock?

Tried 82, 83 and 84 Hz

82 working (333 pixel clock)
83 working (338 pixel clock)
84 NOT working (342 pixel clock)

over 84 not working... Looks like 340 Hz limit...

Can you verify which pixel clocks are working?

339 MAX can't go further which limits my monster monitor's refresh rate to just 150hz at 1440x1080

BUT in nvidia's custom resolution I can reach 500+ and apply it on desktop but not in some games

....so how is that a patcher issue ? im dying over here

NVIDIAs custom resolution should work without patching.

It's a patcher issue because the limit applies to EDIDs only, not the NVIDIA control panel.

Looks like they added another 340 MHz check for some reason.

Hi, I asked a question "Does anyone own the Samsung CRG9, or another Super Ultrawide like it? If so, can you post me what timings you used." But no one responded. I assume no one here has this kind of monitor or similar.

Can you help me teak the settings to get 144hz stable? I haven't messed around with the timings. I'm not as used to tuning timings at this resolution using display port 1.4. 144hz works right off the bat but with missing frames. This is using the Nvidia control panel only, Freesync off. Haven't used cru. Don't know if that would make much a of a difference. Don't know if overdrive should be on or off? Also wanted to know if it was possible to get 165hz at 6bits with the bandwidth Display Port 1.4 provides at my native resolution (5120x1440p)?


it is claimed by other people who own it that it can do 144hz no probs at it's native resolution. When I select it, it does set it without issues, but when I run the ufo test there are skipped frames. So something tells me it could be down to a timing issue? Any suggestions to tweak it would be helpful?



8bpc = blank screen. Still under the required 1080hz needed for 8-bit 144hz 5120x1440p


Default timings = works, but 6bpc, frame skipping.

This works! All my custom resolution in CRU are back again and working!
Outstanding support. Thanks ToastyX!

No, timing parameters have nothing to do with skipped frames.

Just an update - solved my issue (regarding CRU's changes not taking effect). It was an Intel Driver issue. Sorry for the confusion.

The laptop has both a NVIDIA GeForce 840M as well as "Intel HD Graphics", integrated graphics. The manufacturer's Intel driver is old and hasn't been updated since 2016. And it refused to allow me to install the latest generic Intel drivers (it complains that the new driver hasn't been approved by the vendor).

With the original driver, deleting "Default extension block" does nothing. However I was able to force-install the latest Intel driver through "Device Manager". This seems to solve the issue for me. CRU's changes are working with it. It seems CRU fails to work on the old drivers, but works fine on the latest ones from Intel.

It's a bit puzzling because GeForce 840M is supposed to be my primary "graphics processor". I guess for some reason, Intel is the 'master' driver and controls the initial resolution switching before invoking the secondary driver.

I did encounter a strange issue though. When adding the custom resolution 1278x720 (without using it), and restarting via restart.exe, it sometimes didn't come back after going black. I had to hard-reset. Other resolutions seem fine such as 960x540. Although restart.exe switches to black more than once when executed, whereas the Intel-supplied software that adds custom resolutions only switches to black once.

Also, CRU doesn't seem to see the custom resolutions added by Intel HD Graphics Control Panel, but upon saving in CRU, it erases the custom resolutions set by that software.

Cheers - great software

CRU is separate from Intel custom resolutions. When you make a change with CRU, Intel treats it as a different monitor.

Hi toasty,
Before I begin to address my problem, i would like to show my gratitude towards your hard work into this software and your continuous support.
I've been using your software since 2017 and recently I switched over to a newer laptop with switchable graphics(nvidia mx150) with intel uhd 620.
I can get an oc of only 65hz whereas in my old laptop(only intel hd 4400), I could go upto 78hz. Is it because of a different panel that's in my new laptop? Or is it because of some driver limitations, if so, can I bypass it?
I'm really not very knowledgeable about this topic so I'm sorry if I had missed something!
