Good morning and thanks for reading me. I just installed Portsdownw but the screen is turned and the touch doesn't match. I bought this on amazon https://www.waveshare.com/product/raspb ... case-a.htm
unfortunately I couldn't find the original raspberry .. is there a way to use it or is it better to return it to Amazon ??

Thanks and 73 de i4wrm Ros

You should be able to invert the display by going into Menu 3, then System Config followed by Invert Touchscreen

Not sure what you mean by 'touch doesn't match' Are you saying that the button's function labelling doesn't match what happens when it is touched?

I should add that only two screens are supported on the Portsdown 4;

The official Raspberry Pi 7 inch which has a PCB like this:

or the DFRobot 5 inch that has a PCB like this:

No other screens are supported, even if they use the DSI interface and are 800 x 480 pixels.

Thanks again Clive for the clarification. Today I am sending the screen back to Amazon and I will try to find an original one.. 73 de i4wrm

I have several Portsdown 4s and have one 7inch screen that would not turn upside down to mount in the available case! I think it had a fault. I used this screen for another project that did not need to use the invert screen. So sometimes there may be other screens that have this fault.

Good evening and thanks Martin for answering me. Maybe I was unlucky and anyway I already ordered the original Raspberry display and returned the one I couldn't get to work to Amazon. Thanks again for the answer. 73 of i4wrm Ros
