5 inch display for Portsdown4

Post by Don_EI8DJ » Mon Jan 24, 2022 1:33 pm

Hi all,
Further to the discussions on the nets with regard to 5 inch displays for the Portsdown4.
I have the following unit, a TFT50 from one of the usual Chinese suppliers running on my
PI4. see link

Initially the screen display was fine but the touchscreen mapping was inverted so the BATC wiki advice was followed with
the addition of text " display_rotate=2 " to the end of file in /boot/config.txt, fixing the problem.
After running the portsdown4 update the configuration held so all should be well for further upgrades.
Just remember to un-comment or remove the additional text should you need to revert to the 7inch display again.
Best regards to all, Don EI8DJ / MOJJY

Any display that is not supported is not supported. I would not advise getting anything that is not supported, even if it is cheap because it is not supported and therefore by definition it is not supported. Hopefully that's clear enough. Don't buy a screen that's not supported and expect it to work or to be supported .
