Monitor seems to have a Problem

Can someone help please?

I have an Acer C700 tablet which I connect to a larger monitor for ease of vision. This is part of an older Desktop PC running Windows 7, which I use as a backup. The Acer is connected to the monitor via a HDMI/USB lead. For the last three months, the monitor does not read the Acer signal. I have tried changing the lead but it makes no difference. Could this be a Windows 10 fault?

Does the tablet screen still show?

DO you have to use control panel or keyboard to switch to external monitor?

Hi Fruit Bat, The tablet screen is unaffected.The monitor, connected by a lead, has a touch-screen control to switch from one computer’s display to the other. So at the moment, it’s PC display or nothing!

Many Thanks

check the display settings in windows 10 on the tablet, wondering if it shows as second display or is just mirroring the tablet screen. Check things like refresh rate if incorrect would result in no picture.

Also check in device manager for any exclamation marks against display drivers.

I followed your instructions as best as I could. Refresh rate is stated as 60 Hertz, and was unalterable so I couldn't do anything about that, so not much joy so far. Drivers all appeared to be up to date. Under "Display" in Settings, there is a Multiple Display icon with a Detect button under it. I also tried that, but with no success.
