Degraded display

[Ludobzhh]

Hi all

I have a display issue I was not able to solve.

Some of my pictures are degraded as well as some pictures in the net .

I downloaded to windows 10 and got the same issue.

When I open pictures in another computer I do not have the issue .

When I make a screenshot I do not have the issue as well .

I took pictures with my mobile and circle the issues .

Is someone has an idea ?

I checked all  drivers they are ok 

Thx for your support

Hi 

After discussing with HP support I found the solution 

1) came back to Windows 10 

2) reinstall  BIOS ( not sure it is necessary )

3) reinstall graphichs driver Ghrapics (not sure it is necessary )
https://ftp.hp.com/pub/softpaq/sp113001-113500/sp113012.exe

 restart the unit after each installation

After these 2 steps the issue was persisting 

Last step I install last HP Display control 4.7.88.0 RevA

issue solved !
