How can I disable the blue LED on the bottom of my Acer ED270UP Monitor? I’ve checked the settings but can’t seem to find any option. I also want to avoid using tape. Thanks.
To do this without using tape (or blu-tack etc) you might have to do one of the following ...
open the case and
get your electric drill out and hope your destruction doesn't penetrate the PCB and that any LED fragments that fall inside are non-conducting or do not land anywhere they will cause a house-enveloping fire.
Frankly a small piece of tape is a better solution. For things where cosmetics matter I sometimes use small round stick-on paper disks of the sort that used to be used on wall-calendars/planning charts
For really bright LEDs you might need to epoxy on a small disk of aluminium foil cut using a hole punch.
