HDMI colors are awful - Intel graphics 520

[ArielElia95]

Hello,
I own HP EliteBook 840 G3.
The GPU is Intel graphics 520.

First, when I plug my PC to a TV screen with the VGA the colors are great and there are no problems.
When I plug my PC with the DisplayPort (with an adapter to HDMI but that's not the issue) to a TV (tried LG and Samsung) with a HDMI cable, the colors are awful, the blacks are bad, other colors looks weird, it hurts my eyes looking at it.

Now, from a research I did on it, it has something to do with the Intel graphic driver settings.
Most of the answers are to turn RGB to full range, which I did but didn't help, and I saw a solution for AMD GPUs to turn pixel format to 4:4:4 - but I don't have an option for that with the Intel drivers.

The problem is 100% with the driver and the HDMI connector, the question is what setting should I change?

Thanks.

Hi

Under windows resolution is hz set to optimum? Often with connecting Tvs this setting can change to 29/30hz instead of 60. See if that makes a difference.

Naming or changing if theres an option for the hdmi input channel in the tv menu to 'pc' can help.

I don't know how to see the hz in windows resolution but in the Intel driver it sets to 59P. Changing it to 60P or 50P doesn't change anything.

I can't name the output, only add a sub-header (like HDMI😛C which doesn't help either).

I tried to download MadVR and use madlevelstweaker (checked the box of force PC levels) and rebooted, and nothing has changed.
I do have the quantization option, and already marked it to be full range and it didn't change anything.

Maybe I was using the madlevelstweaker wrong?

Possibly. It could be the adapter cable too. Club3D released an dp to hdmi cable with praise being an adapter that works properly. Not sure how your adapter compares but its an option to look into.

I got a new adapter, something that should work. And his problem happened to other people too and the fix was a software one.
