Question Black annoying pixels after GPU change (depends on brightness)

[FunKy552]

Hi,
I changed my gpu yesterday from a gtx 1060 (3gb) to a gigabyte rtx 2070 super and I love that performance but I have one problem, in NVIDIA Control Panel I had always my brightness on +75% if I leave it now on + 75% I can see this ( https://prnt.sc/ozy3s6 ) when I change my brightness to +50% everything is fine. I have a two monitor setup and it is the same on both of them. I dont know what I should do I did not find any solution for that and I just like having a brighter screen.

try to calibrate your monitor settings (search or type in start -> display color calibration)

Well.. that calibration it is exactly the same if I lower my brightness to +50%, the problem here is that I just like when my screen is brighter and if I set brightness after the calibration to +75% I can still see that pixels. I just want them to disappear on +75% brightness, sadly is this calibration not working for me.

thats quite low resolution image
u sure its not dithering whats acting up?
whats your screen resolution?
anyway even if i use 100% brightness (in nvidia settings) its still much darker than what u have on first picture...
even on maxed out gama...nothing extreme
while contrast makes those artefacts appear much visible
u sure u calibrated it rite?

My resolution is 1920x1080, I played Control yesterday and it was horrible, there are a lot of dark scenes and all of them had this pixels... well I can try to calibrate it again but im pretty sure that I did it right

see nvidia control panel -> change resolution -> use nvidia color settings -> output color 8bit, ouput dynamic range full
this will disable dithering
if u cant select full color range
then open registry
HKLM\SYSTEM\CurrentControlSet\Services\nvlddmkm\State\DisplayDatabase\YOUR_DISPLAY_NAME_HERE
add new binary key there
name: DitherRegistryKey
hex values: db,01,00,00,10,00,00,00,02,00,01,04,f3,00,00,00

if u cant add new key, right click on monitor and select permissions, add your admin profile there
once done, reboot or restart gpu driver

And which of them should be my monitor? I have two one of them is an Acer K242HL (My main Monitor) and another is a Philips 23IE

ok, so I did it and basically nothing changed I can still see the pixels, maybe I should try to reinstall gpu drivers?

And yeah that SAM0 is my TV but its not plugged in right now because im waiting for a displayport to hdmi adapter

EDIT: Reinstalling gpu drivers didnt work
