DIY 800×600 LCD Secondary Monitor Guide

If you have an industrial LCD screen, say an 800×600 "snowflake" display, you can try turning it into a secondary monitor. If you're interested, this DIY guide could be really helpful for you.

First, you need to make a case for the LCD. Considering cost and ease of construction, you can stack layers on top of each other. You can draw the frame for each layer in CAD, then cut them out with a laser cutter.

Once you have the screen, you'll need a driver board. You can use one similar to the board shown in the picture below.

After getting the display ready, you can also prepare a Raspberry Pi 4B with 4GB of RAM, a matching case, a power supply, and other accessories. This will complete the base setup.

For better overall aesthetics, easy assembly, and durability, you can get a camera-style stand, like the one shown below.

You can tidy up the wiring later to make it look cleaner. Then you can install the system and boot into the desktop environment.

If you want to get the optimal image quality from this screen, you can refer to the instructions in the official manual and make the necessary adjustments.

If the sound quality isn't great, you can also check the manual for this piece of code and modify it accordingly.

By doing this, you can output audio directly from the Raspberry Pi's headphone jack, and the sound quality will be excellent.

And just like that, your DIY project is complete.
