Detected limited range output levels
Using TV encoding range of (16-235)/255

means that the Rgb output is set to limitedRGB.

If you deleted the extension block and the monitor is detected as DVI, then the video card is sending full range RGB for sure. The problem might be that the monitor is expecting limited range RGB with HDMI, so it ends up clipping the full range.

I believe you're right.
Maybe is a false positive but i can get fullrgb (whit displaycall) only if i turn on LG "smart energy saving".

I try to calibrate the monitor with this option on.

thanks for your patience

Hi, I am new around here. I have an LG monitor and the model is Flatron E2250 (id:gsm578e). I am using HDMI. I'll be straight, I need full settings for CRU. My goal is getting 85hz on 1920x1080. I don't know if it helps but my gpu is RX 480 and the driver is AMD Crimson 19.1.2. Much appreciated.

Also newish to CRU. I have a 4k monitor that I can get to output 71Hz (stable) using the Adrenaline custom resolution/refresh rate tool. But when I manually enter the settings that work there, in the CRU 'detailed resolutions' window and reset the driver, the monitor refuses to output anything. Choosing "Automatic - LCD reduced" icw 3840x2160@70 or 71Hz doesn't work either.
Anyone have a clue what may be causing that, and/or what I can do to work around it?

Ok, so following my inability to add audio to my cibox monitor i some how messed up my gpu driver..
Then i reinstalled it, but didnt remember to use the pixel patcher. so my display was garbled on my samsung monitor. (i then reverted that to a defaultresolution)

Now i remembered i had pixel patcher before so i reinstalled it. but i cannot get my samsung as450 synkmaster back to 1900x1200 @75 herts..
I did have it working perfectly before even did all those monitor tests like the ufo one and stuff to verify...
but i just cannot get it to work now.

I think what i did the 1st time was (but its not working now. so im probably not remembering properly)

i used the nvidia custom resolution tool.
Changed the timings to cvt reduced blanking
then changed the polarity of the horizontal from either + to - or - to +

But now it wont work..

Kind of annoying. (i probably should have saved the thing, but i didnt expect to mess up the drivers)

Any help on making this work?

Some games just crashing when i set higher monitor freq
Why!?
Could it be cause i resetted non x64 ?
And what difference between them?

Games shouldn't crash unless there's a hardware problem or driver bug. Restart.exe automatically calls Restart64.exe on a 64-bit system, so that doesn't matter.

What happens when you do that? 1920x1200 monitors usually can't handle higher refresh rates, but if you got it working before, then I would expect CVT reduced blank to work. You shouldn't even need to change the polarity.

The same timing parameters should work with CRU, and the screen shouldn't blank out unless you changed the current resolution to something incompatible. I wouldn't expect LCD reduced to work with most 4K monitors, but LCD standard and native should. Are you using HDMI 2.0 or DisplayPort? Does this monitor have FreeSync?

I haven't seen anything that indicates that monitor would handle 85 Hz, but it can probably handle around 75 Hz. Just add a detailed resolution and try LCD standard/native/reduced.
