$15 · Acer 23 inch Computer Monitor 1920 x 1080

Power and HDMI cables included Note, there is a small hardly noticeable "dent" in the center of the screen, like a speck that doesn't wash off, but all the pixels work perfectly. I used it for years like this with no issues. I would have kept using it as a secondary screen if I had hot downsized my workspace.
