I've been using this monitor with no issues for a long time. Since some months however, the USB has started glitching. I especially have issues with my Logitech Webcam as well as my USB Keyboard. The webcam is increasingly glitchy up to a point where it is not useable anymore.

The keyboard sometimes works fine, but sometimes is also not usable: when i type something, suddenly it is as if a key on the keyboard get's stuck, like I'll be typing and thennnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn .... something like that happens.
Is this a known issue and is there anything to do about it, or is the screen just end of life? Would really be a shame because apart from that, the screen is still great.
