Review on 🖥️ High-Quality 3.5 Inch Raspberry Pi 4 Touch Screen with HDMI, TFT LCD Mini Display and Stylus Pen for Pi 4 B, 3 B+ by Kerrick Restoration

Revainrating 4 out of 5

Some issues but it's good enough for the low price.

Works like a charm. It's very, very, very small. The board is almost the same size as a Pi 2 or 3 board and is designed to connect directly to a Pi 2 or 3. I'm not going to connect it directly (my Pi is in a case, but I took that to test), but it's designed to. I haven't tested the touchscreen yet (not sure I'll bother with that) and there's an audio jack, which I'm not sure I'll play around with for any purpose either. I hooked it up to a cheap PSU to see how it behaved and everything worked. This thing doesn't use a lot of electricity. While it's ready to go right out of the box with no display fiddling, there are still plenty of caveats to consider. The panel in particular is painfully cheap. You get what you pay for and all that, but one more thing to mention: visibility. not polite. The panel used appears to have been originally designed for vertical use, but it is a TN display. The end result is that half the screen is brighter than the other when viewed straight off the center. The viewing angle is largely shifted to one side of the screen. The backlight is also a bit weak overall. The thicker bezel side protrudes slightly above the screen (I'm currently working on an 800x600 screen), so configure your Pi to suit your needs. Something that's not quite interlaced happens where you can see half the pixels in the checkerboard update and then the other half and it looks a bit flickering. This is very evident when you move your head. Also, as far as I can tell, there's no way to stop the screen from stretching input to fill the screen. As for other remarks, it comes with heatsinks. You will need them! Place one of the large heatsinks on the large chip on the back as it gets very hot during operation. The other two look like they're for the Pi, but I already have heatsinks on mine. Also, seriously, don't increase that resolution beyond 800x600 if your use case allows you to control the input resolution. The screen is too small and the resolution too low (480x320!) to be useful.

To get pixelated output from the Pi, set your own video mode in your boot.txt. Something like this: #starthdmi_cvt=480 320 60hdmi_group=2hdmi_mode=87#end The first line defines the user mode, the second and third tell the Pi to display that mode. Overall it's simple, fairly well designed, and the worst issues of many are the rather awkward viewing angles and screen tearing. It's not very expensive, accepts HDMI, and fits perfectly (it's actually perfect) with a Pi 2 or 3. Plus, the box looks like it's the perfect container for everything if you don't have a case. It's just the right size and that's it. Cut out some small holes and bam.tl;dr: good: it's easy to use, has a good form factor and it's cheap bad: the screen is very low resolution, it flickers a bit and is a little blurry: built-in - Screen tear

Pros
  • High marks for support and durability from testers
Cons
  • poorly thought out
