So i bought a new pc monitor yesterday and after a couple minutes i started to get green dots on the screen. But i spotted it doesn't occur when i connect through display port. Its only hapenning on two hdmi ports. Hdmi ports are broken or what?

It could be a bad cable or a loose connection, in my experience there is always something wrong with hdmi.
Display port is the better cable to use!
If you need to use the hdmi, have you tried switching cables, or wiggling the connector a bit to se if the dots dissapear?

I checked two cables and two hdmi ports in my monitor. Green dots still appear. So its not cable. Green dots dont appear on DP slot

Is there any particular reason for you to not stick with the DisplayPort connection if it works well?
I wouldn’t bother discovering what’s wrong with the HDMI connection...

Low quality HDMI cable most likely (both of your cables). Get HDMI 2.0/2.2 certified cable.

BTW - what monitor model? What graphics card are you using?
I highly doubt thats the cable related issue. It worked fine on my older monitor and the cable costed more money than usuak cable and its certified gold cable.
My monitor is
Samsung Lc27rg50
And my graphic card is : rtx 3060ti
