Looking Glass @ 1080p when the real monitor hooked up can only do 1024x768

Operating Systems & Open Source Looking Glass

Hello,

is there a way to run Looking Glass at 1920 x 1080 (Full HD @ 16:9) when the real monitor hooked up to the card passed through the VM can only do 1024 x 768 (EVGA @ 4:3)?

I assume you would have to emulate a monitor that can do full HD in order to let the graphics card adress it. But how would I do that in the Virt-Manager and did anyone do this successfully? (I assume yes, but couldn’t find that step in all tutorials I remember…)

You can’t emulate a passthrough monitor, you need a dummy plug for your GPU that reports the resolutions you want to use.

Any tips on which dummy plug to get best?

They are all pretty much the same, just a HDMI connector with an EEPROM inside, there is no ‘better’ or ‘worse’ versions. Just pick one that will report the resolution (or higher) that you intend to use.

Thank you! Connector has arrived and worked great yesterday.
