HyperPixel 4.0 display review
By Phil King. Posted
We first covered the HyperPixel way back when, and it's still one of the best Raspberry Pi displays around. This is the rectangular 4-inch model, but there's also a square version. It also comes with optional capacitive multi-touch if you need that.
Whichever version you choose, this is a HAT that mounts onto any Raspberry Pi computer's GPIO header. Since it uses nearly all the pins to communicate, that does mean it can't be used with other HATs, but the I2C pins are broken out so you could connect a sensor.

The 800×480 display is stunning, running at 60 frames per second with great pixel density and 18-bit colour (enabling 262,144 shades). Unlike most similar screens that use the standard SPI protocol, it uses a high-speed DPI interface that enables it to shift five times more pixel data. Note that to use it with the latest version of Raspberry Pi OS, you'll need to add a line in the config.txt file to use the kernel drivers.
Verdict
9/10
If you want a display HAT, this is one of the best.
