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:pC 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?

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