Hi everyone!
I think I love CRU, it solves great bugs of NVIDIA drivers when choosing resolution. I created 1680x1050 as at this resolution the TV displays text in best way.. and I solved the audio HDMI problems thanks to this forum (!!)
but I'm not satisfy 100%, the panel is real FullHD (Samsung 32" LED TV) and displaying at native resolution I've oversized desktop and text isn't displayed correctly.
There is a way to fix this? What values I've to put for displaying correctly at native resolution? Thank you a lot!
PS: I'm quite newbie to this settings, may you kindly help me step by step? Thanks!
I see a lot of people posting related issues here so I guess it's a good place to ask for help. I bought the BenQ GW2760HS, marketed as a 75Hz panel. With Dual DVI I can't use over 60hz, it becomes blurry, but otherwise works "fine". With HDMI, any HDMI, it works great at 75hz but I get static, like white ants across the screen. I'm dying for a suggestion on how to fix it. I got the R9 290, if it matters.
Well, I'll be darned. I've been trying to solve this issue for damn near 6 days without any progress, and five seconds after posting on this forum I solved it. Now I feel like an idiot. Anyways, I solved it by setting LCD-Reduced at 74.990hz. Hope this helps someone down the line.
GW2760 75Hz for posterity.
I'm not sure if this is the best of places to ask this question, but I see people asking all over the place and I -think- I narrowed down my problem to the CRU. I'm using the QX2710 Evolution II 1440p monitor and up until recently it had been working fantastically for me. I'm using a Sapphire R9 290 tri-x graphics card and I had successfully overclocked the monitor to ~110 - 115 hz.
Just recently I used drivesweeper (now DDU) to sweep out my drivers and start all over again because all the past updates were clogging up my computer. I reinstalled 16.1 for windows 10 64 bit, but whenever I try to overclock my monitor to 1920x1080 it just gives me a black screen. Even if I leave it at 60 hz, it gives me a black screen whenever I try to switch to it. Every time I try to do the custom resolution from the new amd control panel, it says it's not supported and automatically reverts it.
I can successfully patch my driver with toasty's patch, and if I switch to 1920 x 1080 without using cru it's fine, but as soon as I try to set up a custom resolution, it messes up. I tried the reduced lcd or standard lcd (whichever it was) fix that toasty had put in their little FAQ, but whenever I do that, it automatically reverts to manual timing. So I'm at a loss for what to do. I'm probably missing something very simple. Can anyone help?

Why are you trying to add 1920x1080? The QX2710 is a 2560x1440 monitor without a scaler. It doesn't support non-native resolutions. By adding 1920x1080 using CRU, you're telling the driver that the monitor supports 1920x1080 when it does not. You need to add higher refresh rates at the native resolution, 2560x1440. The driver will automatically add some common resolutions like 1920x1080 as scaled resolutions.

That monitor is single-link DVI. It will not display dual-link DVI signals correctly. Any resolution over 165 MHz pixel clock is sent as a dual-link DVI signal unless the driver is patched:

That means the scaler can't handle the resolution. Sometimes using different timing parameters will help.

That's one way to keep the pixel clock under 165 MHz, but the video card won't reduce the memory clock when idle with a lower vertical blanking/total.

Because there are some games I play that are just too overwhelming for my card at that kind of resolution. I like to tone it down to 1920x1080 for those kinds of games, but when I fullscreen them it messes up my second monitor, which is 1920x1080, and when I do borderless windowed, it just scales up the resolution back to 2560x1440. What I don't get is why it worked before and it doesn't now, you know? But I removed the old custom resolution and switched to to the 1920 one and it looks like the hz stayed. Thanks for the help. Guess I'm just dumb

The only way it could have worked before is if you added both 2560x1440 and 1920x1080 with GPU scaling enabled, but you don't need to add 1920x1080 anyway because that's one of the default resolutions. Any refresh rate you add at the native resolution will be available at lower resolutions as scaled resolutions.

Don't delete 59.950 Hz until you know 144 Hz works.

If you can't get 144 Hz to be available at all, then the driver is not allowing it for some reason. Try higher horizontal blanking/total values by raising the front porch/sync width/back porch 8 at a time like this: 16/24/24, 24/24/24, 24/24/32

Unfortunately, i got the "out of range" box when windows booted up 
, ending up having to do a safe boot and go back to the old driver (luckily safe boot worked now, unlike back in the win 10 beta)
No, what's weird is you were getting that message at all. If the resolution is not available, how can it be out of range? You should not be getting that message unless you deleted all the other resolutions and removed the extension block. Then the driver might be setting some lower resolution that your monitor doesn't support.
Hello, I'm new to the forum and found it because of an issue I'm having with a Radeon 7600G and a new monitor. CRU lists the resolution I want, but I can only achieve 1920x1080. Hopefully there is a way. My laptop works fine (AMD 8540), but I haven't got what needs to happen for it to work. Any help appreciated!
Thanks.

How is the monitor connected? DisplayPort? HDMI? If HDMI, did you try the pixel clock patch?
