Hi, I don't know how to explain my problem, but I try hoping that someone would understand and help me fix it.
So I have one HP Elitebook (I think it is 820 G2) with 16GB RAM and Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz. The issue is that when it starts with its own display the colors are OK, but as soon as I activate an additional display the colors get messed and it is looking ugly like described https://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/820-g1-Ubuntu-Screen-artifacts/m-p/7029819/highlight/true#M188601) It is not clear to me what should I do to solve it. Thank you in advance -- FCD6 3719 0FFB F1BF 38EA 4727 5348 5F1F DCFE BCB0
