How to assemble your monitor hardware

• If the computer is turned on you must turn it off before continuing.
  Do not plug-in or turn-on the power to the monitor until instructed to do so.

• The following illustrations are for your reference only. Available input and output jacks may vary depending on the purchased model.

• Avoid finger pressure on the screen surface.

1. Attach the monitor base.
Please be careful to prevent damage to the monitor. Placing the screen surface on an object like a stapler or a mouse will crack the glass or damage the LCD substrate voiding your warranty. Sliding or scraping the monitor around on your desk will scratch or damage the monitor surround and controls.

Protect the monitor and screen by clearing a flat open area on your desk and placing a soft item like the monitor packaging bag on the desk for padding.
Gently lay the screen face down on a flat clean padded surface. Orient and align the stand base socket with the end of the stand arm. Make sure to align the arrow on the end of the stand to the one on the monitor base. Turn the base counterclockwise until you cannot go further.
As illustrated, when the stand and the base are locked, the arrow on the end of the stand is aligned to the lock symbol on the monitor stand. Raise the thumbscrew lids and tighten the thumbscrews as illustrated. Then push the lids back. Orient and align the stand arm with the monitor, then push them together until they click and lock into place. Carefully lift the monitor, turn it over and place it upright on its stand on a flat even surface. To move the monitor, you must hold the handle and the bottom of the stand base at the same time as illustrated. You can protect the monitor using the supplied dust cover. You might want to adjust the monitor stand height. See Adjusting the monitor height on page 22 for more information.
You should position the monitor and angle the screen to minimize unwanted reflections from other light sources.
2. Connect the video cable.
The video cables included in your package and the socket illustrations in this document may vary depending on the product supplied for your region.

The default settings (ECO mode and enabled ECO Setting) with dimmed colors are mandatory settings to keep low power consumption and meet the international energy standards, which limit the display performance as a result.
To utilize your monitor, select CONFIRM to change modes/settings. Note that any change to the default display settings may consume more power.
10.Change the display language.**
If you want to change the display language, go to System > OSD Settings > Language . See Language on page 55 for details.

How to detach the stand and the base
1. Prepare the monitor and area.
Turn off the monitor and the power before unplugging the power cable. Turn off the computer before unplugging the monitor signal cable.
Protect the monitor and screen by clearing a flat open area on your desk and placing a soft item like a towel on the desk for padding, before laying the screen face down on a flat clean padded surface.
Please be careful to prevent damage to the monitor. Placing the screen surface on an object like a stapler or a mouse will crack the glass or damage the LCD substrate voiding your warranty. Sliding or scraping the monitor around on your desk will scratch or damage the monitor surround and controls.
2. Remove the monitor stand.
While pressing and holding the VESA mount release button (1 ), detach the stand from the monitor ( 2 and 3 ). 3. Remove the monitor base.
Raise the thumbscrew lids and release the thumbscrews as illustrated.
In case you intend to use your monitor on the stand in the future, please keep the monitor base and monitor stand somewhere safe for future use.

And then detach the base from the stand. Adjusting the monitor height
1. To adjust the monitor height, hold both the left and the right sides of the monitor to lower the monitor or lift it up to the desired height.
2. On the monitor stand is an adjustment scale that helps keep track of your preferred monitor height. Move the marker on the scale to the monitor stand height just set.
Avoid placing hands on the upper or lower part of the height-adjustable stand or at the bottom of the monitor, as ascending or descending monitor might cause personal injuries. Never place your hand on the stand either when tilting the monitor upward or downward. Keep children out of reach of the monitor while performing this operation. Viewing angle adjustment
You may position the screen to the desired angle with the monitor tilt, swivel, and height adjustment functions. Check the product specifications on the website for details.
Tilting the monitor
Tilt the monitor gently. The scale on top of the column helps keep track of your preferred tilt angle. Swiveling the monitor

1. Turn the monitor to the left or right as desired.
2. Turn the adjustment scale on the monitor base. The interval of measurement is 5 degrees, and you can make adjustment within the possible swivel angle. The scale on the monitor base helps to keep track of your preferred swivel angle.

Rotating the monitor

1. Pivot the display.
   Before rotating the monitor with a portrait viewing orientation, the display has to be rotated 90 degrees.
   Right-click the desktop and select Screen resolution from the popup menu. Select Portrait in Orientation, and apply the setting.
   Depending on the operating system on your PC, different procedures should be followed to adjust the screen orientation. Refer to the help document of your operating system for details.

2. Fully extend the monitor and tilt it.
   Gently lift the display up and extend it to the maximum extended position. Then tilt the monitor.
   The monitor should be vertically extended to allow to rotate from landscape to portrait mode.

3. Rotate the monitor 90 degrees clockwise as illustrated.
   To avoid the edge of the LCD display hitting the monitor base surface while it is being rotated, do tilt and extend the monitor to the highest position before you start to rotate the display. You should also make sure there are no obstacles around the monitor
   and there is enough room for cables.

4. Adjust the monitor to the desired viewing angle. See Viewing angle adjustment on page 23 for more information.
   If the monitor has been rotated to portrait mode and height adjustment is desired, you should be noted that the wide screen will keep the monitor from being lowered to its minimum height.

Installing the Shield (shading hood, optional)
To help focusing in games, the Shield (shading hood) avoids the unwanted disturbance interfered with the peripheral vision while playing.
For models that came with shading hoods, two shading hoods are inside the accessory box. Please be careful to prevent damage to the Shield and the monitor. The shading hoods are well-designed and can fit into your monitor properly. Do not use excessive force when installing Shield to avoid possible damage.
For models that did not come with shading hoods, you can purchase them separately. Visit ZOWIE.BenQ.com for the availability of XH250.
