    Changed monitor resolution, now monitor says "input not supported"


    I installed Windows 10 and found some apps did not fit the monitor screen (too big). I went in and changed the monitor resolution to a larger size (windows recommended 1920 x 1080) but I tried something larger, and now the monitor has a black screen with a little box moving around which says "input not supported". Not being able to use that monitor to go in and change it back, I hooked up a flat screen t.v. which worked but Windows only showed the current monitor size (which was smaller than the original monitor. I tried the monitor on another computer I have also running Windows 10 and it worked fine. It shows the resolution as 1920 x 1080. When I plugged it back into the original computer I get the same plack screen with "input not supported" so I can't change it there. I suspect the issue is with the registry somewhere in Windows 10 on the first computer, but I have no idea really what the problem is. I've been working on this for a whole day now. You can probably tell I'm not well versed in computer technology. I just want my old monitor back (Acer K272HL) and I promise I won't mess around with it again. Does anyone know how to help me?

    Not your model, but this article may help with some procedures. Acer Monitor says "Input Not Supported" - Forums - CNET

    Thanks for the reply Dick. I've checked a number of possible solutions and it looks like most say to re-boot in Safe Mode. I can't find a "safe Mode" in Windows 10. If I plug in the "non-working" monitor, I can't see anything on the desktop to even try. There has to be something in the registry settings to change this. The last time I tried to install Windows 10 from Windows 7 my computer crashed and I had to hire a repair guy to get me up and running by re-installing Windows 7, to the tune of $200.00. I should have left well enough alone and stayed with what I know was working.

    Safe this way....Settings/Update and Security/Recovery/Advanced Startup and restart now. You will be taken to a boot option screen, where you can go into advanced or something like that and you will see all the safe boot options. Can't do it and get you screenshots cause I'll be out of the OS at that point. Just look at the boot options, you'll find it.

    You can also do this quick tutorial written by Shawn (Brink) which let's you set Safe Mode boot options from the desktop context menu. It works perfectly. Safe Mode - Add to Desktop Context Menu in Windows 10 - Windows 10 Forums

    Thanks Dick, I now know how to enter "Safe Mode". I think I'll give Shawn's method a try to make it easier next time. The monitor works in Safe Mode but when I restarted the computer it went back to the "Input Not Supported" screen. But at least I have something to work with now. I'll keep trying different things. If you or anyone else have any suggestions, please make them.

    Have you tried to change the resolution in Save Mode to 1920x1080? Save the new display settings and reboot to your normal windows profile.

    I have tried that. It didn't seem to work. I finally solved the problem by adding the monitor that would not work, as a second monitor on my computer. It worked then. Next I removed the first monitor and the original is still working. This is probably not the right way to do it, but it seems to work so I'll be happy WITH IT.

    I also discovered my display had automatically moved to a different resolution. After hours of searching threads with NO help I had clearly learned that the Windows update that had just been applied changed everything in the driver. I went to right click start>device manager>display adapters>ATI Radeon 3000 and opened the application. I clicked the "driver" tab and "roll back the driver". Within 10 seconds the display was back to 1980 x 1080.
    Hope that helps someone. All the Tech's that recommended re-downloading the drivers and jumping through hoops - what a waste. this was easy.
