Hi all,

Quick question. So I got a new Dell monitor but the colours are a bit washed out because the gamma is too high. There's no setting on the monitor to change this (retarded :/) and any attempt I try in windows is futile. What happens at the moment is I'll open up the Nvidia control panel, reduce the gamma to 0.70, I'll then see the screen get darker like I want, then it just automatically goes back up. The gamma however is still set to 0.70. Doesn't matter if I click apply, it'll just ignore it. I've tried this in both Windows and Ubuntu and I get the same result.

It's almost as if internally, the monitor is giving me the middle finger.

Has anyone ever had this? :/

There's also no gamma setting on my Dell IPS screen. I feel the colours are too dark on mine. Have you tried tuning the monitor through Desktop Color Settings in you GPU's control panel?

I have older Dell monitor which only works with maximum intensity settings. When brightness is reduced, backlit goes completely off. I traced it to a faulty LED backlit driver chip. This is El cheapo Chineese PWM controller with no proper English documentation available. It is not the first time I encountered Dell using inferior components.

I think your monitor electronics is faulty.

Are you sure about there not being any way to change settings on the monitor. Can you access the OSD via the 4 little buttons next to the power button?

Have been trying but the moment I change anything the monitor will just change back a second later :/

Have you tried installing a custom icc profile( http://www.tftcentral.co.uk/articles/icc_profiles.htm)?

Tried this this morning, didn't make any difference :(

Can access the OSD but there's no option for Gamma. I can change Brightness, Contrast and have custom RGB colours.

Added a video in the 1st post for context :)

EDIT:

So doesn't look like it's the monitor doing it. Plugged it into my HTPC and I can change the gamma from the Nvidia settings without any issues /o\

PC1 - GTX 680
Windows 10 - Have issue changing Gamma through Nvidia control panel
Ubuntu 16.04 - Have issue changing Gamma through terminal

PC2 - GT 610
Windows 10 - No issues

The only common denominator then is my Graphics card in my main PC :/

Using the same interface (i.e VGA/HDMI) in all cases???

Tried both HDMI and DisplayPort on my PC and got the same result. My HTPC I used HDMI.

EDIT:

So I just finished reinstalling Windows (Got a new SSD yesterday as well) and now it's working fine /o\ I just don't understand when things like this happen :/ Why does it still do the same thing in Linux?? Where did I go wrong in life?? >.<

Windows 10 corrupt itself over a time it is known issue.
Linux I don't know, but at least you can search for better driver and will remember.
