I'm using it on a laptop (MSI GL72 GQD, GTX950m and intel HD 530, i7-6700hq) with a broken screen, with a connected external 120hz monitor. The problem I faced was that most games defaults to 60hz even when desktop was set default to 120hz. My solution was adding a custom resolution below 1280x720 (currently playing on 800x450) and making 120hz the only option for it. However as you might guess it makes games look pretty ugly and sometimes even unplayable. I don't have high hopes for fixing it, but perhaps you have an advise?

If you get rid of all the 60 Hz resolutions on the external monitor with CRU, then 60 Hz shouldn't be available at all. If it's a DisplayPort monitor, all you need is one detailed resolution for 1920x1080 @ 120 Hz and no extension blocks or anything else. If it's an HDMI monitor, import hdmi.dat for an HDMI extension block with no resolutions. Then it should use 120 Hz no matter what.

Okay so I did this like a month ago and it didn't work. One thing I just realized is that when I go 120hz the monitor cuts a lot of colors, an image becomes a lot darker and you can easily define each color when you see a gradient.
Yesterday I properly disconnected the broken internal screen from laptop though, and now external monitor is actually main monitor. I did the hdmi import once again and weird thing happened. After the first restart I only had 120hz option available which is great, but the screen was super glitchy and had artifacts all over it. (Also it seemed to have all the colors, not how I usually see 120hz). I did another restart and it looked like it was fixed. The screen was 120 hz still. I booted up a few games, and they clearly have 120hz now, but for some reason the fps is holding at around 30 frames for some reason (the mouse moves smoothly though).
I'll see what else I can tweak around, but for now it didn't work.

Okay, so I guess three restart do the magic. I was thinking for a while, that disconnecting the broken screen was a solution, but I was too afraid to break the the whole laptop. Thank you again for this tool! Also, is the limited color palette normal? Just in case I'm killing my graphics card or some shit.

It shouldn't behave differently between multiple restarts, and the banding you described shouldn't be happening on the GPU's end with HDMI, but it could be happening on the monitor's end. What monitor is this? Keep in mind that HDMI supports RGB 4:4:4 limited/full range and YCbCr 4:2:2/4:4:4, so if your GPU's control panel has an option to set the color format, the monitor might behave differently with different color formats. The color formats might only be available with "LCD native" timing, and the monitor might behave differently with "LCD standard" timing at 120 Hz, which is normally RGB 4:4:4 full range.

That's odd. For me it like a loot box. Each time I run a restart it gives me a new thing to look at. Sometime it might me completely odd resolution like 640x480, sometime there is a weird stattering or diagonal line going through the monitor. After like 4th restart it might not work at all and only restarting pc reverts it back to normal.
The monitor is 24" benq xl2411z. I believe it's 144hz, but either my hdmi or videocard can only get it up to a 120hz.
Perhaps this might be a reason?

Often times when I restart it just creates a new profile or something like this.

Is this with the latest Intel DCH driver? Some people reported having to copy and paste the settings to both entries to work around odd issues with the DCH driver.

Hi all, this is my first post here. I would like to thank ToastyX for creating CRU.

I would also like to share my experience on enabling G-SYNC on an uncertified Freesync monitor.

The monitor in question is an LG 27MP59G (bought it on sale), and after some tweaking I managed to get it working within freesync range of 40-75hz.
I am using a mini-DP to DP 1.2 cable, because I'm on a notebook (Asus GL702VSK), which has as GTX 1070. I turned off the laptop's monitor and use only the LG as the main monitor, and it's been great so far.
The only thing that I could not manage to fix is this: after the monitor goes into standby, when it wakes up again, the EDID override is "forgotten", as G-SYNC stops working. Sometimes using restart.exe or restart64.exe might fix the problem. But the only reliable way of getting it back to work is by restarting Windows.
Another curious observation, which I guess is only relevant to this monitor (before making any modifications with CRU): after going to NVCP and enabling G-SYNC and checking the "display specific settings", I can check that the video card recognizes the monitor as GSYNC by running the pendulum demo. However, when the fps reaches 37, it goes black for about a second and then turns on again when the fps goes above or below 37. This behavior extends to any game I run fullscreen (did not test windowed modes).
The only way to get rid of this behavior was to insert a custom block with the proper Freesync range with CRU. And after that, restarting the system, since restarting the driver only would not work.

Is there a way to prevent the monitor's EDID override to be forgotten? What I'm doing now is just preventing it from going into standby, by setting a two hour timer in windows power settings.

The EDID override should persist unless there's a graphics driver bug. Do you know if that laptop has switchable graphics? If that's the case, you might have to copy and paste the settings to all the inactive entries in the monitor list because it might be switching to the Intel GPU on standby.

The curious thing is why does the monitor have an HDMI data block? It shouldn't need one for DisplayPort. I would get rid of that. The FreeSync data block is also meant for HDMI. Does editing the range limits not work with NVIDIA?

Hey everyone.

First of all, I want to thank you for this program, which helped me, but right now I'm in a situation that I can't fix even with this program. The thing is, for years I had a monitor which had stutters and after all the hassle I finally fixed it by choosing CVT reduced blank from Nvidia panel. Since then, I've bought a Full HD 75Hz Freesync monitor but the one which has HDMI and not DP, but that's not the problem. The problem are the stutters which are also occurring on this monitor too (seems like I have a very bad luck with monitors). I did kinda fix it with CRU, I mean no matter what would I choose in CRU settings, it would make it much better than stock settings, but there were still an occasional stutters, but that's with Nvidia. Not a long after, I bough an RX580 for that freesync which is working flawlessly, but that's were the big problems started. First of all, I chose to go with 60hz as with 75hz videos on youtube didn't feel right for me, they weren't as smooth as on 60hz (obviously), but just to quickly point out, 75hz was also stuttering, just a bit less. Now, the issue I have are these stutters which are really bad sometimes and watching videos/playing games is unpleasant (forgot to add, 75hz especially with Freesync is actually smooth and without stutters, but Youtube still stutters). Another problem is that AMD overrides the CRU settings, when I set my own resolution in CRU, AMD control panel still reports the default settings of the monitor, but when I set the same resolution in AMD settings, everything still stutters and this is something I've been battling for a while now and can't fix no matter what I do or choose. So I came here for your advises, maybe someone can point me out to somewhere?

Things I've tried:
Reinstalling Windows
Reinstalling drivers
Turning off Freesync
Different cable
Setting higher minimum clocks

Here are the default values:




Sorry for a long ass post, I'm just really tired of this problem.

I really need to see a video of the stuttering to understand what's going on. Monitors don't normally stutter at stock settings, and the timing parameters shouldn't affect stuttering, so the problem is likely something else.

I did record a video some time ago but strangely stutters were nearly invisible, at least they didn’t look close to being as bad as they are in real life.

Another thing I’ve found is that 1080p videos are actually smooth and stutter free, it’s 2k or 4k videos which are stuttering. This is strange given the fact that my PC is more than capable to run these resolutions. Also, as I said, with my old monitor the fix was to set CVT reduced blanking resolution. With this monitor and Nvidia card I did minimize the stutter by setting the custom resolution in CRU, but with AMD it’s always the same. And can you tell me why CRU can’t override AMD settings? Or is it normal at this point?

Thanks for replying, I will record a video as soon as I get back home.

EDIT: Forgot to mention, youtube doesn’t report any dropped frames even with all the heavy stutters.

Setting "CVT reduced blank" shouldn't affect smoothness. CRU should be able to override with AMD. Make sure the same resolution doesn't exist elsewhere because that might take precedence. Export your CRU configuration to a file and post it here, and post a screen shot of what AMD's control panel shows.
