Some people say if you setup just 60 then freesync doesnt use value of 60, the higer value it use in such setup is 59, that's why you should put 61. Don't kbow if it's true or not, as i mentioned above, my monitor goes with both refresh rates at the same result.

By the way, i got rid of artifacts in games by setting up limits to 19-61 Hz. Don't know how it works and how it helped.. But Pendulum if i simulate 40-60 works smooth, if i simulate 50fps - works smooth as well, but if i simulate 60fps - sometomes i see tearing. So freesync doesn't work 100%.

Who knowes how to set it up in details?

If you put 29-61 Hz but the detailed resolution is 59.996 Hz, then the range is 29-59.996 Hz. You need to change the detailed resolution to match.

This is similar to what i ran into when nvidias CP had refresh rates that wouldnt delete, so while i had a 60-65Hz range setup NVCP was forcing 63Hz in some titles - and I got that weird flickering bar at 64-65FPS, while 65Hz worked fine on the desktop

You gotta make sure you have the ranges correct to match the new details, or it wont work

(Fast vsync was related somehow, but not the primary cause of the problem - it was adding +1 to the refresh rate and definitely not meant to behave that way, 60Hz became 61Hz etc)

I have an issue seemingly with a wrong refresh rate (but maybe i misunderstand the tool)

This is my monitor:
https://www.asus.com/displays-desktops/m.../techspec/

It shows 60 hz instead of 144 Hz. I added 3 images with what i see. This is wrong, do i have some wrong settings or what is going on, can you help me understand this. I did not edit anything yet its the first time i opened the utility and it displays this info. The monitor is reporting 144 Hz though to be honest something seems off, playing at 60-100 Hz looks so bad it seems like 30 and bellow. Wondering if I didnt mess up something some time ago and the monitor got stuck with some wrong settings

Appreciate all the help if anyone has any ideas

Also can i delete those? Why are there so many entries, are they from old plug and play actions that were saved in registry or something?

I don't see a problem. Your screenshots show 144 Hz is in the extension block, and you even highlighted it. If you're using a refresh rate supported by the monitor, then any performance issue is usually on the GPU's end, not the monitor.

Every connection to every port and even different drivers can cause a new entry to appear. You can remove all of them. Active entries are automatically recreated after rebooting or running restart.exe. Running reset-all.exe and rebooting will remove everything and reset the active entries. Running restart.exe can have the side effect of creating a second entry because of the basic display driver, but that isn't used.

I have watched videos how to properly do it and the same thing happens every time. if you have any idea what this is and how i can possible fix it pls lmk.
here is what is looks like.
sorry if u gotta download the video idk how else to do it since the file is too big

CRU does not deal with scaling other than defining what the native resolution is. Scaling is up to the monitor or the GPU if GPU scaling enabled. If the monitor can't display a resolution correctly, then use GPU scaling. Even easier, you can add GPU-scaled resolutions using this instead: https://www.monitortests.com/forum/Threa...Editor-SRE

So i tried to use CRU, add 4k@165hz through extension blocks+ displayid 1.3/2.0. I can add 165hz4k via CRU but no matter what i do i dont see those options at nvcp and windows display settings. I did use all the restarting software it came along.
When i reopen CRU i can see my custom refresh rate resolutions at the extension block.

What to do? Thanks for the help.

Also idk if its important, when i first open CRU it shows 2 default extension block.

The first post says NVIDIA does not support default extension blocks and will ignore all changes if a default extension block exists. I don't know if NVIDIA broke something recently because CRU is supposed to be able to read the extension blocks.

When anyone get a solution for the problem i spent him a tip in paypal! :-)

You just need a CTA-861 extension block with an HDMI data block and HDMI 2.x data block with the FRL rate set. That's the bare minimum to make it work.

Being VA panels they have some smearing and while i can use CVT-RB2 and get 10 bit, i notice more of that black smearing - so i'm working on the various options to see what works best.
I was trying to figure out the highest bandwidth that gave me 10 bit without just raising values in increments, but also didnt want to waste time if i raised the wrong value or the display tech simply doesnt work that way.

Blanking wouldn't affect smearing, which is caused by the slow pixel response times of VA panels. Each pixel is updated at a fixed interval based on the refresh rate regardless of the blanking. Changing settings like contrast and color profiles can change what shades are affected by smearing, but that just shifts the smearing to a different set of colors.

Thanks for info, I now have a better understanding of the tool usage and i see all the monitor modes in the second screen indeed

If I may ask a different question. I have the GPU memory locked at max freq (2000Mhz in my case) and also dealing with some input lag (some gpu drivers way worse than others) and I am thinking to use another mode to see if GPU memory will go down

I found that some people fixed this using a different timing. Is there a risk running pixel clock at 346 vs the max reported(330 in my case)? I attached what it looks like if i chose that timing. Am I understanding correctly that the monitor is being instructed by the OS on how to operate by altering the registry? Or its a gpu driver change as well?


Also would this have an impact of how fast the image is being displayed right? Could this add / remove some perceived input lag? I'm troubleshooting Rocket League and its a very fast paced game

If this would fix the gpu memory issue with no impact in games it would be nice

I just came to a major discovery

The image on my monitor was always terrible at high fps (200-240 for example), felt like micro horizontal tearing over the entire screen when moving the image sideways. Yesterday I created a custom resolution for 120 Hz and i chose CVT RB Standard. Set the refresh rate to 120Hz in Windows and tried the game at 240 fps. Now I finally have a smooth image similar to playing 144Hz and the game at 144 Fps. And it's so much more responsive, seems the input lag is gone

Clearly something is wrong with this monitor running at the default settings (120, 144 there is no difference, the image so so bad when running any game above 144, it becomes unplayable)

I do get some occasional tearing but limited to a rather thin line even with this solution so I wonder if I could try and alter a bit any of the settings so that 120Hz + 240 FPS becomes crystal clear? Any help appreciated

If you're using DisplayPort, then 346 MHz is fine. Technically more blanking means it spends less time visibly refreshing and more time between refreshes, but the difference is miniscule and not worth worrying about. CRU creates EDID overrides in the registry, which is basically a description of what the monitor supports. It's not really altering anything in the registry since there's no override by default. The GPU driver will use the override if it exists. Otherwise it uses the monitor's EDID.

What you're saying makes no sense because the monitor already uses CVT-RB for 120 Hz by default. Tearing will always happen outside the adaptive sync (FreeSync/G-SYNC) range. The only way to avoid tearing is to cap the frame rate within the adaptive sync range or use vsync, but that would add lag. Also when you use a lower refresh rate, higher refresh rates are no longer included in the adaptive sync range, so the effective range at 120 Hz would be 40-120 Hz. Maybe you should try with adaptive sync off because that would have the least lag at the cost of visible tearing.
