Which display for the Raspberry Pi3 Server (Touchscreen)

in Repetier-Server
Hi Guys,

I've already made a thread a while ago with the touchscreen I bought (whatever thing from Ebay, 3.5" with the GPIO-connector only), which was non-working.
(My problems can be seen here: https://forum.repetier.com/discussion/5880/waveshare-spotpear-raspi-3#latest)

But for now: I'm willing to try it again - can anyone recommend a display to me, which is known to be working with a server installed from the image downloaded from this website?
And it would be good if I can order it in Germany.

Please don't tell "any GPIO-connect 3.5-inch display is fine", because I already got two non-working ones here.
I'd like to know a product (sure, the cheaper, the better), which you already use and had no hassles to put it into operation.

Regards,
Maeffjus

    We use the official 7" touch display from raspberry pi foundation. That gets stacked on the pi and uses the flat cable hdmi cable for communication. With that display you can use our images with no modification at all. Other hdmi displays should work as well but are untested. Only these tiny displays using frame buffer require modifications to use the correct frame buffer driver and settings.

    Thank you! But I think that also some 3.5" display was shown in the manual - which one is that?

    I think it was a waveshare display, but that needed lots of tweaking in linux to get it running. Was a long time ago I have set it up with an older raspbian. That is not what you want as easy solution. What might be easier if you have such a display is to use to os image from the display vendor and just install repetier-server on it. Most tricky part is to autostart chromium  with the touch interface in full screen in kiosk mode.

    The waveshare displays worked for my without big issues (3.5" and 5") if you use the configuration package that is on github (https://github.com/waveshare/LCD-show.git). You only need to start the correct script and this does all the necessary changes.

    BUT:
    Just a few days ago I found this display (7") https://www.amazon.de/gp/product/B07PKLGMSY/ and I am more than satisfied. It's very cheap, is 1024 x 600 and works perfect with my Raspberry Pi 3 B and Repetier-Server Image V16. The touch function is just like on a tablet, so you don't need a pen and no calibration...

    The setup is also very easy:
    sudo apt-get install git
    git clone https://github.com/goodtft/LCD-show
    cd LCD-show/
    sudo ./LCD7C-show
    sudo reboot
    This display is connected via the HDMI port (the GPIO connector is not used and stays free for other things!) and the touch function is connected via USB (so this costs you one USB Port). But connecting the USB also powers the display via this connection.

    Now this setup is 'my' control center next to my 2 printers and one WebCam and works like a charm.

    Hi chofmann,
    I bought this one just yesterday - should be delivered today!
    I'm looking forward to it ;-)

    Thanks for the steps needed! I'll gladly use your guidance for installation ;-)

    Thanks, finally the display worked out of the box, without any driver!
    But I had to add the following into the boot.txt:
    (This fixed the distortion of the picture)
    hdmi_cvt=1024 600 60 3 0 0 0
