Ensuring that your Dell monitor is set up properly - assembling the monitor stand and setting up the monitor ergonomically, connecting the cables and organizing them, will only help make the viewing experience the best it possibly can be.

Attaching the stand

The standard monitor stand is detached when the monitor is shipped from the factory. To learn more about attaching the standard monitor stand, refer to the Setting Up the Monitor section in the User's Guide of your Dell UP2720Q monitor.
To learn how to set up any other stand with a monitor, refer to the respective stand setup guide for setup instructions.

Caution: Do not remove the monitor from the packaging box before attaching the stand.
 
Note: The Dell UP2720Q monitor and stand is 9.71kg; handle with care when you lift or move this monitor.

Ergonomics

Where you put your monitor is almost as important as what model you buy. The monitor should be directly in front of you, at an arm’s length away (between 20-40 inches from your eyes), with the top edge of the screen at eye level when you’re sitting comfortably. You may need to adjust your chair height or the height of the monitor to achieve this.

Connecting your monitor to the PC

To connect your Dell UP2720Q monitor to your PC:

  1. Turn off your PC and disconnect the power cable

  2. Connect the DisplayPort, or VGA cable to the corresponding video or display port on the back of your PC

To learn more about connecting your monitor to the PC, refer to the Dell knowledge-base article How do I connect a monitor to a PC?.

Use the buttons at the bottom of the monitor to access the On-Screen Display (OSD) menu of the monitor. To access the On-Screen Display (OSD) menu, press Button 5 (Figure 1) at the bottom of the monitor.

To learn more about how to use the On-Screen Display (OSD) menu, refer to the Operating Your Monitor section in the User's Guide of Dell UP2720Q monitor.

Note: Any changes you make are automatically saved when you move to another menu item, exit the OSD menu, or wait for the OSD menu to automatically close.

If your Dell monitor has a blank or black screen, fuzzy or blurry image, flickering, distorted or any other screen abnormalities, running a diagnostic test will help determine if the Dell monitor is functioning normally. To learn more about diagnostic options on a Dell monitor, refer to the Dell knowledge-base article How do I run diagnostics on a Dell monitor?

It is always essential to isolate the monitor while troubleshooting your computer for the following scenarios:

  • No Power - Your computer is not powering ON or showing any signs of power.
 
  • No POST - Your computer is not showing any indication of activity, the screen might be blank and will not display the Dell logo during start-up.
 
  • No Video - You are unable to see any display on the screen, able to hear the windows chime but no display is seen.

Your Dell UP2720Q Monitor provides a self-test feature check that allows you to check whether the monitor is functioning properly. If the monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove the video cables (VGA, DVI, HDMI or DisplayPort) from the back of the computer.
  3. Turn on the monitor.
  4. Turn off your monitor and reconnect the video cable: then turn on both your computer and the monitor.
  5. If your monitor screen remains blank after you use the previous procedure, check your video card (GPU) and computer, because your monitor is functioning properly.

Your Dell UP2720Q monitor has a built-in diagnostic tool that helps to determine if the screen abnormality you are experiencing is a problem with the monitor or with the video card on your computer.

When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade etc., it is always a good practise isolating the monitor by running the Built-In Diagnostics.

  1. Make sure that the screen is clean (no dust particles on the surface of the screen).
  2. Unplug the video cable(s) from the back of the computer or the monitor. The monitor will now enter self-test mode.
  3. On the front panel, press and hold Button 6 on the front panel for 4 seconds. Select Option screen appears.
  4. Press Button 5 to highlight the Diagnostics icon. A gray screen appears.
  5. Carefully inspect the screen for abnormalities.
  6. Press Button 1 on the front panel again. The color of the screen changes to red.
  7. Inspect the display for any abnormalities.
  8. Repeat step 6 and step 7 to inspect the display in green, blue, black, white and text screens.
  9. The test is complete when the text screen appears.
  10. Press Button 1 to exit the Built-In Self Test diagnostics.
Note: If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor is functioning properly. Check the video card (GPU) and the computer.
If you notice any abnormalities during Built-In Diagnostics, you may get the monitor repaired/replaced if it is under warranty by contacting Dell Technical Support.

During the LCD Monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state which is hard to see and do not affect the display quality or usability. For more information, refer to the Dell knowledge-base article Dell LCD Monitor Pixel Guidelines.

This section provides information on troubleshooting steps that can help resolve the most common issues with the Dell UP2720Q monitor.

Unable to switch back to native resolution (5120 x 1440) after Picture by Picture is turned off

Dell UP2720Q supports Picture by Picture (PBP) mode. Picture by Picture (PBP) mode is 2 side-by-side images with each image displayed at 2560 x 1440 resolution.

When the monitor is connected to a PC via 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).
  1. Disconnect the HDMI cable
  2. Wait for 5-10 seconds
  3. Connect the HDMI cable
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," depending 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 behaviour is by design in Microsoft Windows.

Switch to the display mode that you want after you close and reopen the laptop screen manually:

  1. Press the Windows logo key + P on the keyboard
  2. Select Second screen only or Projector only mode

Dell UltraSharp & Gaming monitors are inspected with a tighter criteria of 70 lux ambient lighting (dimly lit room but not completely 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 centre of the screen.

Dell UP2720Q 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.
