I inherited an older 27″ Acer monitor from my son. At first it looked great, nice big image, all wonderful.
Then I woke up the laptop this morning and the Acer said “Input not supported.” I went to Display Settings, tried adjusting the resolution, etc — no joy. Then I rebooted, and poof! Everything is happy.
Then the screen saver shut off the monitor, and when I woke it up, same behavior again. Rebooting again resolved the problem, for now.
I tried looking online for ideas, but everything I found seemed to assume the monitor didn’t work at all, and you just had to adjust something and it would be fine. But this monitor has been working great for a week, and then suddenly it goes belly-up. Reboot and it’s fine, then a little later it’s out again, and another reboot fixed it. Both times it’s done this, it was waking from a sleeping or screen-off state.
I even went to the Acer site to see if they had a driver for it or something. They had .INF & .ICM files, for Windows 7, but I gave it a try anyway. (I’m on Windows 10 Pro.) “The third-party INF does not contain digital signature information — even though I got it directly from https://www.acer.com/ac/en/US/content/support-product/4261?b=1
Is something hosed with this monitor, or with my laptop? (HP Spectre x360 15)
