I had a blast building a MagicMirror, but the final product is disappointing because the modules are dim, especially when there’s plenty of light in the room. I used the cheapest ($75) 17-inch monitor on Amazon and standard 1/8 inch Acrylic from Tap Plastics. Any suggestions on a brighter monitor? I want to stay with 17-inch.
First, I would play with your monitor controls to see about getting more light to transmit through your acrylic. Up the gamma first, the contrast second and then adjust the brightness. The brightness will also affect the black areas of the screen, so don’t just crank it all the way up.
If that doesn’t work for you, then yeah you may wish to investigate a new monitor.
