Dell Inspiron 3542 Brightness adjustment and HDMI output issue
I have a Dell Inspiron 3542 with OS windows 10. Recently I got an issue of no HDMI output - does not recognise monitor which before did - and own monitor brightness cannot be controlled either from direct keys F11-12 or the monitor settings, where the brightness bar is completely absent. The issue was temporarily solved after many updates in Windows and even BIOS, I installed SupportAssist by Dell which installed all latest driver updates. Unfortunately the problem came up again and I cannot see any solution. I read somewhere that it can be a malfunction of the video card drivers.
I would appreciate a suggestion to a possible solution for my problem. Thank you in advance!
