ok so i have further noticed that the issue is when i am using HDMI cable to 1 monitor causing this lag. like there is a delay or something but without HDMI connection all working OK, any suggestions?

sorry guys, i managed to fix this,
Only display on external monitor
played with the resolution - and refresh rate increased which fixed the issue it seems.

Thanks for posting the follow-up. Please mark your post as the solution if the issue is indeed fixed.
