## Description

desertcart.com: ELEGOO 7-Inch 9K Monochrome LCD with 8520x4320 Resolution, Compatible Mars 4 Resin 3D Printer : Industrial & Scientific

Review: Works well and Easy to install - This solved the issue I had with dead space in the printer. Relatively easy to install, though the video has a glaring error. It shows having to remove and replace the LCD and glass seperately. The one I got had both pieces pre-assembled together. Trying to follow the video is gonna leave you with broken or scratched glass. A piece of advice, wait until you have tested whether the LCD works. Mine didn't the first time and I had to redo the wiring connection. Worked second time, but I now have several wrinkles in the tape. Whether this will inhibit printing has yet to be determined. If you wait until everything works before you do this last stwep it will reduce any issues.
Review: good but expesive - Great replacement but mine broke, it was my fault

### ⭐⭐⭐⭐⭐ Fit like a glove with easy install.
*by S***K on April 19, 2025*

It fit like a factory part should and fixed the issue with the printer. My child had no issues swapping out the old screen and replacing it with this new one. Printer works like new again. With the help of a video the installation was very fast and simple. Now to just start printing again.
