Gaming monitor with a 165Hz refresh rate and 2560x1440 resolution. - Model: 27GP83B-B - Resolution: 2560x1440 - Refresh Rate: 165Hz - HDR Support: OFF - Response Speed: FAST - Connection Terminals: DisplayPort Thank you for viewing. There are no dead pixels or unevenness on the screen. I used it with a monitor arm, so the stand is unused. Please see the screen for usage time. As a bonus, I will include a 3m DP cable 1.4. Includes original box, and other parts are unused and in the box. Will be shipped in the original box. *This monitor seems to have poor compatibility with HDR, so I used it with the setting OFF. The color is beautiful, so I am satisfied even with it OFF.
