Blanking video on a single display w/DisplayPort Connection

Some users have noted that using a single U3415W curved display may not display video out of the box. It has been determined that these systems will display video when the DisplayPort input of the U3415W is set to DisplayPort 1.1.

NOTE: The U3415W supports both DisplayPort 1.1 (DP1.1) and DisplayPort 1.2 (DP1.2), however the out-of-box default setting on the monitor is DP1.2.

Workaround:

We need to set the U3415W to DP1.1 mode for single monitor operation.

To switch monitor to DP1.1:

If you are able to see video, go to the monitor On-Screen Display (OSD) menu using the monitor menu buttons and change the DisplayPort 1.2 option to Disabled (Figure 1).


Figure 1

If you are unable to see any video, unplug all video cables from the display and perform the following steps using the monitor menu buttons (Figure 2):

  1. Press the button next to Power button to open the monitor On Screen Display (OSD) Menu
  2. Select Display
  3. Select Input Source
  4. Select DP or mDP (depending on your connection)
  5. Press and hold the green check mark button for approximately 8 seconds. When the DP1.2 message box appears, select Disable.
  6. Exit the Monitor On Screen Display (OSD) select Disable.

Light leakage on four corners of the screen

The U3415W display has a curved screen providing optimal viewing position from the center of the screen. When testing a display for light leakage, this should be done in normal ambient lighting, this issue should not be inspected in dark room.

Due to the screen curvature, some corners of the screen may appear to have minimal light leakage, especially when displaying a dark image in a dark room. This is normal monitor behavior for curved screen and typically does not affect overall viewing performance (Figure 3).


Figure 3

All U3415W monitors are inspected per the industry standard, which is with 150 lux ambient lighting (similar to typical office lighting). Any visual inspection should be done in the same manner.

Slight color variations

The U3415W display has a curved screen, because of this design, the optimal viewing position should be from the center of the screen.

Due to the screen curvature, some corners of the screen may appear yellowish or pinkish, especially when displaying a dark image in a dark room. This is normal monitor behavior for curved screen and typically does not affect overall viewing performance.

Workaround:

Turn on Uniformity Compensation:

  1. Open the Monitor On Screen Display (OSD) Menu
  2. Select Display
  3. Select Uniformity Compensation
  4. Select ON
  5. Exit the Monitor On Screen Display (OSD) Menu

Image retention / Image sticking

The U3415W may experience a slight Image Retention when a static image is displayed on the screen over extended periods of time. This is normal In Plane Switching (IPS)/ Place to Line Switching (PLS) panel behavior.

Workaround:

Do one or more of the following:

  1. Always use a screen saver where possible.
  2. Run LCD Conditioning to reduce minor cases of Image Retention.
    1. Open the Monitor On Screen Display (OSD) Menu
    2. Select Others
    3. Select LCD Conditioning
    4. Exit the Monitor On Screen Display (OSD) Menu
    5. Let the display operate for 20 minutes

Image ghosting

The U3415W is factory tuned to provide the best viewing performance for office and graphics productivity usage. Due to this preset configuration, certain applications with fast moving images (e.g. fast moving games), imaging ghosting, which appears as a trailing shadow, may occur (Figure 4).

Workaround:

Change the Response Time:

  1. Open the Monitor On Screen Display (OSD) Menu
  2. Select Display
  3. Select Response Time
  4. Switch between Normal or Fast to find the best performance for your application
  5. Exit the Monitor On Screen Display (OSD) Menu

No video

The Monitor Power LED is On, but there is no image on the screen. The display will give a on screen error message may say "No XX Cable detected" (Figure 5)


Figure 5

Workaround:

Follow the following troubleshooting steps:

  1. Ensure video cables are properly connected. If using a DisplayPort (DP) cable, ensure DP cable on monitor side is connected to DP-in, not DP-out.
  2. Remove all other video cables besides the one you intend to use. (E.G. If you intend to use DP, remove the High Definition Multi-media Interface (HDMI) cable from the system and monitor).
  3. go into Monitor OSD menu
    1. Press the button next to Power button to open the monitor On Screen Display (OSD) Menu
    2. Select Display
    3. Select Input Source
    4. Select DP or Mini DisplayPort (mDP) (depending on your connection)
    5. Exit the Monitor On Screen Display (OSD) Menu

No video on DisplayPort on Windows or Mac

Ensure that Power LED is ON, but No Video from the screen.

NOTE: The U3415W supports both DisplayPort 1.1 (DP1.1) and DisplayPort 1.2 (DP1.2), however the out-of-box default setting on the monitor is DP1.2.

Workaround:

To switch monitor to DP1.1:

If you are able to see video, go to the monitor On-Screen Display (OSD) menu using the monitor menu buttons and change the DisplayPort 1.2 option to Disabled (Figure 6).


Figure 6

If you are unable to see any video, unplug all video cables from the display and perform the following steps using the monitor menu buttons (Figure 7):

  1. Press the button next to Power button to open the monitor On Screen Display (OSD) Menu
  2. Select Display
  3. Select Input Source
  4. Select DP or mDP (depending on your connection)
