Create an executable bash script somewhere which runs your python command, for me this contained

#!/usr/bin/env bash
distrobox enter cv -e ~/.virtualenvs/cv/bin/python3 "$@"

which allows me to use a virtualenv I have in my distrobox container directly. Note the "$@" at the end. This is imperative so that commands like ... -m pip can work.

tldr: Fringing happens because the subpixels are not properly aligned. It can be alleviated by "shifting" the underlying data to colocale in the center of the pixel. On the Samsung Panel, a simplistic solution to this is as follows:

green_amt = 0.2
red_amt = 0.4
blue_amt = 0.3
for i in range(1, im.shape[0]-1):
    for j in range(1, im.shape[1]-1):
 green_out[i, j] = green[i, j+1]*(green_amt) + green[i, j]*(1-green_amt)

IMPORTANT: DON’T USE THIS GUIDE AS IS. GNOME HAS A WEIRD VSYNC ISSUES. Instead you can use the official Debian image and make sure all the updated drivers are installed and the rest should remain the same.

Preamble

This guide is made using the Orange Pi 5B 4GB+32GB. The device is capable of handling a 4k 120hz stream but you should know that the decode time for 4k stream hovers around 8ms and can spike up to 15ms during a benchmark. I can’t feel any added latency from it and I don’t have any dropped frames. The decode time goes down to 4ms for 1440p. It’s certainly not the blazing fast sub ms decode latency we get on the Steam Deck or mini PCs. I bought the device for $99 and for that price I think this performance is fantastic, but your mileage/expecations may vary.

How to get this result (or rather how I got it)

1. Install the official Gnome Ubuntu Jammy image using Balena Etcher onto a 16+ GB microSD card
