intermittent fuzzy screen


I get an intermittent fuzzy screen (unreadable). it happens for a few minutes every 10-15min.. any ideas???

fyi - I use 3 screens and connect to another computer using 3 screen.. all works fine, except about 5min a few times per hour I get this fuzzy/unreadable screen. I use a Win11 machine connecting to a Win10 if that means anything? I am using TeamViewer version 15.34.4
