Review on 📺 Waveshare 3.5inch RPi LCD (B) 320x480 Resolution Touch Screen IPS TFT Display for Raspberry Pi - Direct Plug-n-Play for Enhanced Display Experience by Warren Hess

The screen is not smooth or fast. There's serious lag and the screen shakes unless you dig into the config files and lower settings. If you want to rotate the screen, your mileage will be different. When I first rotated the screen, every color was inverted, but I was able to find a few forums where people found a workaround. The second time I tried this the color was inverted and the refresh rate went back a century and I couldn't find the same forums with a workaround. None of the Waveshare pages I've seen mention anything about this issue. This is useful for a web browser or static images, but nothing that actually moves or requires input. To get at least 50 frames per second on the screen, everything looks fuzzy and distorted.
