I have UD-ULTCDL, i noticed there’s big lag using my mouse and keyboard, at first i was thinking about battery… so i bought couple of batteries but it didn’t help. I restarted my Mac (Sierra 10.12.5) and it was still lagging… I booted my laptop to Win10Pro, it was responsive but still jumpy… Im a really fast typist and Im telling you, this is pain in the neck… I almost break my keyboard out of frustration, but before I went overboard I decided to plug the USB receiver directly to my laptop and to my surprise, it’s flawless… I felt bad blaming my keyboard and mouse
Anything I can do so you can troubleshoot and help other users like me??? I can’t believe there’s no final solution for this problem. I’ve seen a lot of thread about lagging issue and i don’t know where to start. Every thread is an open case. Let me know what to do and I will participate just to close this case.
