ASUS ROG SWIFT PG278Q 27 inch Gaming Monitor used but in good condition . It looks like some pixels are dead but if you look closer with a magnifying glass it appears that they're on but blocked by some debris behind the LED panel hardly noticeable when gaming. Please see images. It's an Nvidia G-SYNC with 3D Vision 144 Hz screen with 2560x1440 resolution and it comes with the original power adapter. Pick up only please as I don't have original box . Any questions please feel free to ask.
