Setup for a DSI 4.3 inch display

Help and Support
1

Hi.
I have a 4.3 inch waveshare DSI monitor which I have connected to a PI4 with the latest OSMC release but when I boot it I get the splash screen but then nothing. If I have an HDMI screen connected I get the OSMC home screen displayed as it should be.
Am I missing some setup to get the OSMC home screen on the 4.3 screen?
Thank you for your help
Keith

Quick search on DSI gives this

This should indeed do the trick – but it will incur a performance penalty.

Thank you guys for the swift response.

Will it slow the whole Pi down or just the rendering of the screen. I normally run this Pi as a TV recorder headless but I got given a screen so thought I would run it here for doing the upgrades
