Hello,

I wanted to ask who I can solve my “quality” Problem. I connect my Ipad with a FULL HD Panasonic Video Projektor. Tagtool on Ipad runs great. Everything clear. But when I look on the projected white wall I see a saw tooth (Sägezahn), means pixel in the curves of the painting. How can I solve this? I think I tried everything…

Thank you

Gene

- Did you activate Anti-aliasing in the Settings under External Display?
- Also in the same menu there are settings for the external display resolution. Choose the 1920px width option.
- Restart Tagtool after making the adjustments

Hope that helps!
