Try a different DisplayPort cable. If your GPU has dual-link DVI, try that.

I bought a new DisplayPort cable and the problem remains the same. My GPU is GeForce 1080Ti. Didn't try DVI yet.

Well, after some years I come back again seeking for help.

I have an ODD like hell display.



The display try to display a 1280x1024 image. And then cut the other part off, or dont display it.

If I create a custom resolution of 1280x343, and use standard monitor settings, the image gets stretched.

If I create a custom resolution of 1280x343 and use custom timings, the image gets out of the displaying range. "Still there, but you can only see 1/2 of it at most"

Any help? I cant get the front porch value above the value needed. "That was the setting i used back on nvidia control pannel, now in AMD"




As noted https://www.monitortests.com/forum/Threa...21#pid6321 I managed to did it with nvidia control pannel back in the day.

Also I didn't document it, but managed to did it without having to put the 1024 active pixels, just 343 on the resolution and active pixels, just squishing the front porch, wich can't be done with the CRU. As they are coupled together.

There is any old version arround there that let me use those unlinked? I tryed the older versions and all seems ot be capped at 63


EDIT:> After playing with the monitor and CRU I did I again :# Im like a monitor wizzard of some sorts.
I Managed to move the image up, use CRU to reset the settings, get the monitor to restart the V Position setting to the defaut value "50%" then crank it up again, reset, get a wierd crash, and back in the loop.



Sorry I broke your toy.

Hey I'm using a 20m HDMI cable that I'm able to send 3600x2025 with CVT reduced blanking timing with RGB 8bits 60hz. Including HDR10.

So my tv/receiver seems to accept anything that is under 500mhz of pixel clock.

I tried some calculators but is it possible to have 3840x2160@60 under 500mhz of pixel clock?
My tv accepts 3840x2160@55hz. Any more it is no signal.

Or what would be the smallest front porch, back porch, sync width I can use?
I've been playing with those for a few days but I think asking someone that might actually know what front porch, back porch and sync width does would be a good idea.

Probably not.

1 0 1, but that's not likely to work.

Do you know how to calculate the total pixels needed for 1 0 1?

If it's 3840 it would be +2? 3842?
Same for 2160?

Yes.

Hi guys, I think I have a problem. My monitor (it's an old Samsung B1930, 60hz by default) can support 75hz with the overclock in my native resolution. The problem is when I use it I gets black bars on the sides, not in games but all the time. Is there a way to fix that? I tried every single mode and CRT was the most effective. Thanks

The problem is the monitor is meant to be used at 60 Hz, so the auto adjustment doesn't work properly with VGA at higher refresh rates. The solution would be to use DVI or HDMI instead of VGA, but the monitor only has VGA.

So basically there's no way to make it work correctly right? Now what happens if I play like that or I use it like that? I managed to play csgo on 1024x768 75hz with no borders. Apparently when I open some games borders will disappear

I don't know. I don't have your monitor. I don't see why the borders would just disappear in games. It might support 75 Hz at some lower resolutions.
