Thank you very much MaLd0n,
Only one thing that i do not understand. It's about the Display, i'm using Dell P2319H and my current Resolution is 1680 x 945 (HiDPI) but my eyes usually get strain and it is very uncomfortable, can you give me the advise should i get the new monitor with 4k Res or should i config something. This issue doesn't happen to me when i'm using Window. Thank you again MaLd0n
