On a computer (Mac mini), only hdmi and display port outputs. The monitor through the hdmi → dvi adapter shows well, but without the adapter, only via hdmi, the image is soapy, as if after jpeg. Tried two different hdmi cables. Someone faced? How cured?

Nvidia graphics card? What resolution is determined?
Another possibility is the built-in modes in the monitor (there is cinema, text, normal) - a non-standard mode can soap the picture.

1. Disable Overscan
2. Reduce sharpness
3. Look on the monitor for a setting like "display mode" and set it "as is"
4. Turn off enhancements
Everything is pretty general, but should help.

I heard about this, the matter was decided exactly by some setting in the monitor, to be honest, I forgot which one :(
But I can say for sure that the problem, of course, cannot be in the cable with “blurring the image” and other such artifacts. So that why the cables were changed is not very clear.Then all these hdmi cables for a hundred bucks a meter would make sense, and would not be a scam for suckers)))

Although various solutions are googled for “blurred hdmi image”, such as forum.ixbt.com/topic.cgi?id=4:104182 , but there seemed to be something else there. Doesn't it look like the resolution is still not native?

I noticed that the glitch does not always appear the same way. Sometimes distortion is barely noticeable, sometimes clearly visible. Basically, the red channel is “buggy”, if somewhere there is a small red element with sharp borders. On the monitor twisted all the available settings. There is no overscan at all, there is blur, but it gives a Photoshop blur, not jpeg artifacts. The rest of the settings have no effect.
I tried to connect the TV via hdmi, see if there is a glitch. In general, the image quality on the TV is noticeably worse, but there seems to be a glitch with jpeg-like artifacts too.
So far, I'm leaning towards the version that the monitor either originally had a cheap TV hdmi chip, or a marriage.
