andyapple Posted July 25, 2019 Share Posted July 25, 2019 (edited) Hi, I need help to fix my HDMI output on my Acer Aspire F5 573G with Intel HD 520. This is the situation, and it is unstable: When I connect my HDMI cable the internal monitor of the notebook gets black but the secondary monitor works. To get also the internal notebook monitor working I have to close the notebook for like 5-6 seconds and then open it up, and also the secondary monitor works. So I would like to fix this and get both monitor always working when HDMI cable is connected. I noticed that if I keep the notebook closed, the secondary monitor works in 4K resolution (while if the notebook is open, even with 4k resolution selected the secondary monitor is 1080p), so the secondary monitor works in 4k only if the notebook is closed. And I would like to fix this too. Audio over HDMI is not working and I would like to fix this too. I'm attaching useful report files as EFI and others.
