Guide lines color/weight adjustment

Just started using rhino 8 on a new computer, and I am noticing a huge change in my linework’s color and visibility. On my old computer the line weight visibility was much thicker, and jet black. Now all my axis lines and working linework are hairline and barely visible, and they are a really light gray until the line is completed it will turn to the layer color. Looking for how to adjust the visibility of lines as im working. I can only find info on changing the visibility to the print settings once a line has been made. I dont want to be working with hairline linework as im modelling though, then manually making thicker each time.

Hi Ian -

Do you still have access to that old computer so that you could check the settings?
Did you also use Rhino 8 on that old computer or was that an older version?
Is the screen resolution the same on the new computer as it was on the old computer?

I resolved the problem by changing the application Compatibility properties. (Override high DPI scaling behavior) and selecting ‘System (Enhanced)’. I was running Rhino 8 previously with all the same settings as now, but not on a 4k resolution computer. The 4k I believe is what caused the display discrepancies. Thanks Wim.
