Last year, I was looking for a display to show different information on my home theather computer.
I wanted a display to fit in a 5" 1/4 bay and no LCD technology as I don't want backlight that lights all my room when I watch a movie (high contrast required).
Then I discovered the 3.2" monochrome OLED display ER-OLEDM032 based on SSD1322 chip. Support in Aida64 was implemented by Fiery.
It looks great! Infinite contrast of OLED technology is perfect.
