Ensuring that your Dell monitor is setup 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 U3219Q monitor.
To learn how to setup any other stand with a monitor, refer to the respective stand setup guide for setup instructions.

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 U3219Q monitor to your PC:

1. Turn off your PC and disconnect the power cable.

• Connect the DisplayPort, Mini-DP or DP (DisplayPort), HDMI or USB Type-C cable to the corresponding video or display port on the back of your PC.

Note:Dell U3219Q supports display over USB Type-C port with Alternate mode DP 1.4. Ensure that the USB Type-C on your PC supports Alternate mode DP 1.4

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?.

• Connect the USB upstream cable to the monitor and PC (if applicable).

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 3 (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 U3219Q 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.

Resetting a monitor to factory defaults can help resolve many video or display issues. To reset your Dell U3219Q monitor to factory default settings, follow these instructions:

1. Press Button 3 (Figure 2)on the monitor to enter the On-Screen Display (OSD) Menu.

• Press Button 1 or Button 2 to highlight Others option in the menu and press Button 3 to select.

• Press Button 1 or Button 2 to highlight Factory Reset option in the menu and press Button 3 to select.

• Press Button 3 to confirm the reset action.

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.

• Self Test Feature Check
• Built-In Self Test

Your Dell U3219Q 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.

 

• 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.

 

• Turn on the monitor.

 

• Turn off your monitor and reconnect the video cable: then turn on both your computer and the monitor.

 

• 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 U3219Q 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 to isolate 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).

 

• Unplug the video cable(s) from the back of the computer or the monitor. The monitor will now enter self-test mode.

 

• On the front panel, press and hold Button 1 for 5 seconds. A gray screen appears.

 

• Carefully inspect the screen for abnormalities.

 

• Press Button 1 on the front panel again. The color of the screen changes to red.

 

• Inspect the display for any abnormalities.

 

• Repeat step 5 and step 6 to inspect the display in green, blue, black, white and text screens.

 

• The test is complete when the white screen appears.

 

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.

• Press Button 1 to exit the Built-In Self Test diagnostics.

During the LCD Monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state which are 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.
