Second VGA Monitor “Input Not Supported”

I've just attached a 2nd Acer monitor (G205HV) to my new Acer Aspire desktop (X195-UR21P) via a USB powered VGA splitter. The standard monitor that came with the Aspire is working fine through the splitter but the 2nd screen shows "Input not supported". I'm not tech savvy at all. Is there an easy to accomplish way to get the screen working? Primarily only Excel and websites on the second screen, no gaming or high res stuff.

Thanks!

The message "input not supported" usually occurs when you try to display a resolution which is not supported by the monitor. Either because the resolution or the refresh rate is too high.

Your monitor can display up to 1600 x 900 pixels. How much are you trying to display on it?

Edited:

You did not confirm that you are using win7. If not, please edit your post to indicate which OS you are using. Assuming win7 for now. On win7 your get these screens when you right click on the desktop and select "screen resolution'

Do you have the 'Multiple displays' part? What does it show? Extend or 'duplicate these displays'?

Edit #2: via a USB powered VGA splitter.

A splitter as in a device which can not generate a second image, but which just copies the output from your original video card? That would explain it. Then your windows only generates on desktop and there is nothing you can do about it.

On the other hand, if you meant a device like a USB plugged GPU or one or something like the matrox dualhead2go then you should be able to get two different desktops.

The reason you are getting this message is because the resolution your current monitor is set to does not support the other monitor. You need to lower the resolution in windows.

I had this problem on two pc's. replace the ps2 keyboard with a usb keyboard and do a detect, and that will fix it

I've encountered the same issue, and could not fix it by changing the resolution. Leaving this here for people who will need to fix this issue.

I went to Display Settings > Advanced Display Settings > Display adapter properties for Display 2 (the one that was not working).

The screen refresh rate was at 59. I changed it to 60, then "Apply".

My monitor turned on, but had moved to a weird 640x480 resolution. I changed it back to its native 1600x900, and everything was OK from there.

My problem was solved when I use this information provided by MonsieurPoivron
