HDMI-VGA adapters going to sleep

[SteveB_NI]

I have a large number of basic HDMI > VGA adapters in the College used with our Dell 3050s (Windows 10) to give the users a 2nd monitor - in most cases this 2nd monitor is the data projector - Epson X27s.

 

I'm finding the HDMI adapters are randomly "going to sleep" - and need unplugged / left out for a few secs and re-plugged in for the projector to show the image.

 

Unfortunately as they are added as a "generic monitor" within Device manager, there is no power settings I can adjust for them, nor due to the generic basic nature of them (Newlink HDMI to VGA adapter) there doesn't appear to be any drivers I can find to install.

 

Any suggestions? I've already checked the BIOS and deep sleep etc is disabled.

 

I'm thinking of buying a few USB powered adapters to test, but obviously I'd rather make use of the ones we've already purchased!

 

Thanks

We've found HDMI can be a bit intermittent and requires a reset by unplugging and plugging it back in. Something to do with HDMI Handshake: https://support.channelmaster.com/hc/en-us/articles/200377955-Why-does-my-HDMI-connection-not-seem-to-work-all-the-time-or-why-is-it-intermittent-

 

Not sure if this is related to your adaptors.
