Could anyone suggest a 4.3" LCD display that I can use with a ProMini, or Uno? Someone has recommended this one:

[LCD Display](https://www.buydisplay.com/low-cost-ips-4-3-inch-lcd-display-arduino-spi-i2c-tft-touchscreen-480x272)

The advert seems to infer that it will operate with a Uno, but all the datasheets seem to show shields designed for use with a Mega 2560 or similar sized board. However, being totally unfamiliar with anything to do with screen control, I could be completely mistaken.  
If this screen could be used with a Uno or ProMini, where would I start looking for a suitable library and wiring connections (should no shield be available)?

**EDIT:** _Looking at the video in the advert again, it actually does seem that the Arduino shield will fit a UNO, and by extrapolation I'd be able to work out how to connect to a ProMini, but the question over the library still remains._

at the bottom of the page for the link you shared, there is

that's the code and circuit you should be looking at (it seems they use two _74LV245_ (8-bit transceiver with 3-state outputs) to interface with the LCD).

Right as your message got posted, I spotted that link!  
I've ordered up the 800x480 version to experiment with 👍

Thanks for the pointer tho!
