Question / Help Colours not accurate

Hey guys, i want to create gaming videos.
I noticed that the colours are a bit odd, but the difference is not really big. I want to find out if it is a wrong configuration or if my expectations were simply too high.

I've seen pratically no changes between the colour formats, they were all a bit off.

*Excuse the PC background noise*


I've used this test chart: http://denilson.sa.nom.br/overscan16x9.svg (Credit to denilsonsa)
Notice the big difference in the blue coloured line when comparing to original SVG, it appears darker in the recording.

What i tried:
Setting preference to OpenGL video output (in VLC)
Setting colour range to full 0-255 in Nvidia Control Panel
Trying out all colour formats in OBS
Trying out different encoders

NVENC new encoder
1080p resolution (1920 x 1080)
QCP 15, max quality, profile high
Settings in attachments.

This is a OBS Studio log, so it's on topic here.

Please try to calibrate your setup according to this guide:

Usually it's not necessary to go in to this deep. Usually, the defaults work well. There is always a small bit of color bleeding due to 4:2:0 color subsampling, and the red is becoming slightly different, but that's a common thing with common video encoding. Every video will become this. If not within your workflow, it will become this after upload to the video hoster, since video hosters usually recode every video to their standard settings, which is 4:2:0.
There is more to think about. How is your monitor calibrated? Many monitors today are set too blue/too cold temperature to get a crystal clear, brilliant look. Brightness and contrast is often too high, as well. And if you work late at night, Windows might have activated Night Light (https://support.microsoft.com/en-us/help/4027563/windows-10-set-your-display-for-night-time) to display a warmer image if it's dark outside.

I'll do the test again with those charts and send the results.
I've reset my monitors settings, maybe that will fix the issues.
