Firstly, the vendor—AMAZING SUPPORT! Very quick turnaround! Code input into the terminal was required for this to function. I received it by email quite quickly. My needs are met by the LCD. Nothing special, however it works well for my headless plex server that was previously in place.


As mentioned in another customer review (BigCat), the seller will send a drop box link with instructions on how to make it to function when they message the seller. Plug and play is not the case. It calls for some leg work. nonetheless, is not difficult to understand. Using a Raspberry Pi 3 Model B I'm satisfied for less than $20. A screen grab of the code that enabled the display is attached, however the drop box files also contain a calibration manual and other materials. I hope it's useful.


I currently own three of them. Look around for the best value; I found two from CNE via this site at a nice price. Highly precise and outstanding for perusing text, large spreadsheets, and the progressively complex portals we encounter these days. Narrow bezels, easy to adjust. A work showcase with no bullshit.
