Viewing problems. Lines not solid

They did correct the jagged lines by returning the display to 100% instead of the 150% I had it on but now the text is so small I have difficulty seeing it. Dell was able to increase the text in the menu items but not in the trays. It’s a challenge to find my groups or components, etc. The font appears to be around 4-6 which my old eyes can’t discern.

Also, with my display at 100% even emails are hard to read.

I’ll try your suggestions on the GL settings. If they work and the lines aren’t jagged I could increase display to the 150%

Thank you for your help.

Great suggestion. It would be very helpful.

Changed the GL settings as instructed and returned resolution to 150. Drawing looks good!

Text is still a bit small. How can I increase it?

Thank you
