Does the flickering & ghosting w/external monitor effect M4 Mac minis?

It was present with my P2721Q connected to my M4 Pro Mac mini. I'm not sure if the base model M4 will also be affected. But a suggestion from another post, and the solution for me, was to install a tiny utility called Stillcolor from here. I installed it today and made sure "Disable Dithering" was set and haven't seen the problem since. I'll give it a few more days to be sure but so far the display seems much more stable with no visible flickering.
 
I got base m4 Mini on Black Friday and use it as a 24/7 media server, connected to a inexpensive old Vizio 24" smart TV via HDMI. Image looks good (better than I expected from that old screen which I haven't used in about 5 years!) During setup, it was connected to a Sony 22" 1080p production monitor. Looked good there too. Never saw any signs of flicker or ghosting on either of these but haven't tried any 4k screens.
