LCD Display Enquiry

  1. Can anyone recommend a 3.5" or 4.3" inch touchscreen LCD HDMI interface that is plug and play with the Jetson Nano?

Hopefully the touch function will have a driver so that the software engineer does not have to interpret data from the touch sensor.

  1. Does the Jetson Nano support resolutions less than 640 x 480 or will the display have to down sample the 640 x 480 resolution from the hdmi signal. We don’t want to have a screen with just a portion of the image of showing.

Hope someone has such experience can be shared. Regarding the resolution, HDMI can support up to 3840 x 2160 at 60Hz, it should be no problem for 640 x 480 and no need ‘down sample’.

Sorry. I was not clear. There is an economic need to use 320 x 240 glass with HDMI (or through an HDMI to parallel converter board) because there is no time to develop a parallel RGB hardware port.

I was wondering if the Nvidia HDMI hardware and software go down to 320 x 240 because these converter boards do not scale from 640 x 480 to 320 x 240.


Whether a display mode is supported or not is decided by the driver. Thus, you could check if your display mode can pass below functions.
