It's just padding basically. It doesn't affect the image. CRU is using the CVT-RB standard in that case. The monitor has the vertical front porch and back porch swapped, but that only affects the timing of the sync pulse.

Hi all, I just made an account here to ask a question because I simply cannot find a solution anywhere and this is probably my only hope:

I have a weird, offbrand Electriq monitor that is 4k 144hz when using 2 1.4DP cables (no hdmi 2.1). With one cable it runs at 120hz and I can OC to 130hz no problem. But with 2 I think I can go beyond 144hz but it might be some software/hardware capped (in the monitor bios i need to toggle 144hz mode ON). It's obviously tiling the picture over the two halves of the screen via each cable to achieve 144hz. How can I try OC this with CRU? Is it possible?

Any help is appreciated!

Are there any tips for making my LCD downlclock to 48hz without it becoming blurry?

I can go down to 49hz no prob (actually, 48.9 is fine but 48.8 gets blurry and choppy) -- still nice and sharp. And I can go all the way up to 75hz and it's still nice and sharp.

But 48hz is blurry as hell and it starts getting choppy.

If I manually increase the backporch, it looks a bit better -- but nowhere near as good as 49 or anything else. Does it have something to do with the pixel clock?

AND...

What happens when you just try to OC it to 145hz?

There's no reason it should be blurry. That sounds like a monitor limitation.

Each half should be listed as a separate monitor in CRU. You would have to add 1920x1440 @ whatever refresh rate to both halves.

Oh well... I guess I'll just use 23.977 * 3 = 71.931hz for watching NTSC tv shows then.

I can't add any resolutions on cru. I am trying to force display scaling but when i try to add any ress i cant see on display adapter settings, list all mode.
I want to match my display resolutions and active signal resolutions.
nvidia has the same problem when i set custom res with cvt reduced blank and like others.
When i set this settings my active pixels gone to match my display settings but i cant use causee give me black screen.

My monitor is Alienware AW2521H. Cable is Displayport 1.4.

You say same problem but you mentioned two different problems. Show me what you're doing with CRU and the NVIDIA control panel.

I will explain step by step.
I open cru and delete no active monitors,detailed resolutions and extension block's detailed resolutions.
I add resolution 1920x1080 60hz exact reduced in detailed resolutions part.
I add resolutions 1920x1080 240hz and 1536x960 360hz in extension block's detailed resolution section two res are exact reduced.
I start restart64.
After these steps i cant still see my changes.

On nvdia what i am doing;
I create custom res with 1024x768 with cvt reduced blank timing when i do that my active pixels section match with my display res. But i cant use cause when i try to test give me black screen.

I want to match my game display res and active signal res.
When i use 60hz. desktop res and active signal res match. when i increase refresh rate, active signal res back to 1920x1080p.

Is there a second extension block? Is it a default extension block?

Then your monitor does not support that resolution.
