Unable to switch back to native resolution (1920 x 1080) after Picture by Picture is turned off. | Dell P2422H supports Picture by Picture (PBP) mode. Picture by Picture (PBP) mode is two side-by-side images with each image that is displayed at 2560 x 1440 resolution. When the monitor is connected to a PC using HDMI and PBP mode is turned off, the monitor may display images at the lower resolution (2560 x 1440) rather than automatically switching to the native resolution (1920 x 1080). |

This depends on which was selected before you changed to "Second screen only" or "Projector only" when you close and open the laptop screen. When you close and then reopen the lid on a laptop, the Connecting and Configuring Displays (CCD) feature in Windows automatically reverts the display mode to the last active selection.

|
When changing the monitor’s resolution from Windows Display Settings, the image quality may not be good. | Windows Display Settings and the resolution settings on the laptop's video or graphics utility may not be compatible. | Change the resolution using the video or graphics card (GPU) utility like Intel HD Graphics Control Panel. |
No video when the monitor is connected to a Dell docking station. | The monitor may not receive video signals from the PC when connected to a Dell docking station. | To learn more about how to set up and configure the Dell P2422H monitor with a Dell docking station. See your System Requirements and Supported Configuration in the support site. |
Light leak from the monitor | The monitor appears to have light leak from the edges in a dark room. | This is normal behavior of the monitor. Dell consumer monitors are inspected at 150-lux ambient lighting (similar to typical office lighting). Dell UltraSharp and Gaming monitors are inspected with a tighter criteria of 70-lux ambient lighting (dimly lit room but not dark). |
Color variation on the corners of the monitor | The monitor appears to have color variation on the corners of the screen. | The optimal viewing position for the monitor is from the center of the screen. Dell P2422H monitor uses a curved IPS panel, the corners of the screen may appear slight yellowish or pinkish, especially when viewing in dark room. This is normal IPS panel behavior and typically does not affect the overall viewing performance.
|
No video when a Blu-Ray, DVD player or PS4 is connected to the monitor using HDMI. | The monitor does not display any video when an external Blu-ray, DVD player or PS4 is connected. | Dell P2422H monitor is factory default set at HDMI EDID with three Block (Detailed Timing Descriptor) to support 1920 x 1080 @ 60 Hz. To display a resolution of 3840 x 1080 @ 60 Hz or lower, you need to switch the monitor HDMI EDID from three Block to two Block.
To display 1920 x 1080 resolution over HDMI again, you need to switch the monitor back to HDMI EDID 3 Block. Follow Steps 1 & 2, and Select Disable. |
