Geekworm for Raspberry Pi 4 Model B, 3.5 inch Touch Screen with ABS Case and Pi 4 Heatsinks Kit

The screen is incredibly laggy even at extremely low resolutions. I increased the GPU ram and the issue was not resolved. Thankfully I did not buy this screen for any type of mobile gaming with retro pi, but it's still quite annoying when trying to use a mouse with a screen that's running at what feels like a refresh rate of 5 Hz. Don't buy this if you're getting it for retro pi or any serious work. If you're getting it as a static display for monitoring something, it's okay.

Updated. The screen is good. Instructions are straightforward. The resolution needs to be modified however as the controls are off screen. I’m still working on that. The case is ok but the fit isn’t quite right. Use some glue to secure it. This is probably the best you’re going to find in a 3.5 LCD case. There aren’t many other options out there.

Case doesn't fit together great, the LCD panel is unsupported on the side opposite the connector, and there seems to be limited software support for the display.Wish I had known.

Every time I downloaded the driver it crashes the os

I bought this for my husband and loves it he’s created his own computer with it and leaves me alone now while I’m reading lol I highly recommend

First Pi build and the damned installation wouldn't work.I tried 3 separate Pi OS versions for my Pi 4b and same issue: "unknown switch R".Here's what I know so far:GPIO interface screens don't seem to want to work with DAC. Running DAC install process includes disabling HDMI audio which seems to interfere with video output.If you use a DAC HAT, use a screen that takes ribbon or HDMI input instead of GPIO input.Going to try DAC install process without disabling HDMI audio.Update: Failed.Returned. Ordered a Waveshare DSI instead. Used a provided ribbon cable. Grabbed a no driver version.I doubt I'll bother with GPIO screens on Pi builds again.Also, the one I ordered is the kind where you mount the screen to the bottom of the Pi, so you can add more HATs (fbo Pi noobs: "Hardware Attached on Top". A HAT is a GPIO mounted card).If you want something that works like a TV/monitor with independent power and HDMI to minimise setup, they exist but they're 3 times the price. Your call. I'm only getting started here so the more I learn, the more learn that I don't know 🤔🫤🤷🏻😬😅
