I'm working on an interactive infoscreen-system based on a raspberry Pi 3. For that I need to install the LCD-show driver to the Pi in order to use it as a touchscreen. But the screen I have to use has a 1920 x 1080 resolution and it's a Dell S2240T 21.5'.

I haven't found a way to get the driver for this resolution. And the drivers for other resolutions won't work. Is there somekind of an alternative?

  • I’m not quite sure what you’re expecting to find. Sounds like a plain old PC display to me. It probably connects via HDMI and doesn’t require any drivers whatsoever. – Daniel B Apr 13 '18 at 7:38
  • It's a Dell S2240T touchscreen monitor. Yes its connected with a HDMI but also with a USB for the touchscreen signal.The driver I'm searching is just for the touchinput. – Lin0 Apr 13 '18 at 8:26
  • What you’re looking for isn’t Pi-specific in any way. I’ve never used a touchscreen with Linux, so I cannot provide further assistance, sorry. – Daniel B Apr 13 '18 at 8:36

    Drivers are for devices, not for resolutions. – gronostaj Apr 13 '18 at 10:52

I now used the driver from git. It works perfectly fine with the Dell Monitor and the desired resolution.
