|
The picture does not fill the entire screen. | The picture cannot fill the height or width of the screen. |
|
No Video, No Display | No video when connecting docking, dongle, or Blu-ray DVD players | Due to the legacy platform cannot recognize or output 5120 x 1440, we suggest changing EDID to lower resolution to cover this compatibility problem.
|
Unable to switch back to native resolution (5120 x 1440) after Picture by Picture is turned off. | Dell SE2222H 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 (5120 x 1440). |
|
Display mode changes from "Second screen only" to "Extended mode" after opening and closing the laptop LCD. | The display mode on your PC reverts to "Duplicate" or "Extend." 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. This behavior is by design in Microsoft Windows. |
Switch to the display mode that you want after you close and reopen the laptop screen manually:
|
The monitor blinks twice when connected to PC with an NVIDIA NVS 310 video or graphics card. | When the monitor is turned-off and back on, the monitor may blink twice. This issue may occur if the PC is using a NVIDIA Graphic NVS 310 card and the graphics card resolution setting is 2560 x 1600. |
To resolve this issue, manually set the resolution to 2560 x 1440 using the NVIDIA Control Panel.
|
The monitor has a sound icon when Dell SE2222H is connected to a laptop using HDMI. | Dell SE2222H does not support audio or sound using HDMI. Speakers or headphones must be connected using the audio connector on the PC. |
To resolve the audio icon displaying, update the video or graphics (GPU) driver to the latest version. To learn how to download and update a device driver, see the Dell knowledge-base article. How do I download and install a device driver? |
The monitor will not display Blu-Ray video after the monitor is powered-off and powered on. | If the monitor is powered-off and powered-on when displaying the Blu-Ray video, the Blu-ray player may lose the data signal from the system to the monitor. |
|
Cannot enable YCbCr color mode on the monitor. | When the monitor is connected to the PC using HDMI, the video or graphics card (GPU) controls the YCbCr setting. | Disable the YCbCr setting from the video or graphics utility like the Intel HD Graphics Control Panel. |
The monitor will not support the YCbCr color format when a USB Type-C to HDMI dongle is connected from the monitor to the PC. | Some combinations of USB Type-C to HDMI dongle and video or graphics card (GPU) are not compatible to support the YCbCr color format. |
|
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 SE2222H 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 leaking 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 SE2222H monitor uses a curved IPS panel, the corners of the screen may appear slightly yellowish or pinkish, especially when viewing in a 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 SE2222H monitor is factory default set at HDMI EDID with three Block (Detailed Timing Descriptor) to support 5120 x 1440 @ 60 Hz. To display a resolution of 3840 x 1080 @ 60 Hz or lower, you must switch the monitor HDMI EDID from three Block to two Block.
To display 5120 x 1440 resolution over HDMI again, you must switch the monitor back to HDMI EDID 3 Block. Follow Steps 1 & 2, and Select Disable. |
Horizontal stripes when watching online videos using Microsoft Movies and TV app, Microsoft Internet Explorer or Microsoft Edge | Unwanted horizontal stripes appear on the video playback window when viewing online videos on YouTube using Microsoft Internet Explorer or Microsoft Edge browser. They are also seen while watching online videos using the Movies and TV app. |
