Resolution Glitches On Larger 4k Monitors

[RIKKI TIKKI]

I have been running 6.01.05 and just lately at 2 of my 4 gigs I\'m having problems with the addition of larger big screen monitors ( 65\" 4k UHD ) when using the Marquee and Countdown feature when playing a singers request... I\'ve downgraded the resolution to increase or fill the screen, and once the song starts, the marquee will stop scrolling, and the counter for remaining time will also stop... if I turn off the marquee and the clock it works better, but the Send also has to be shut down for it to playback normally, and not glitch when I add songs during playback, or moving singers around in the playlist... I\'ve upgraded my monitor splitters and switches to 4k compatible units, but to no avail thus far...
So I thought I would see if any of you are having similar problems?
