CHAPTER 2. CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS
1. CONNECTING THE MONITOR AND TURNING THE MONITOR ON AND OFF
Caution: · When connecting, ensure that both the monitor and computer are switched off. · Be careful not to overly bend the cable or add extension cords as this could lead to a malfunction. 3. Refit the cover. Be careful not to pinch the cable.

Cable storage
If necessary, excess cable can be housed in the stand. 1. Remove the cover. Gently pull the top of the cover towards yourself.

· If the cover is hard to refit, do not force it. Check whether cables are trapped. Caution: If the display is to be rotated, first house the cable, and then check while gently turning the display. If it cannot be turned, rehouse the cable with sufficient slack. (If there is insufficient cable length, rotation will be impossible. Forcing rotation may cause cable disconnection.)

1-1. Connecting the monitor to a computer
2. Run cable along the back of the stand. Pass cable in front of the stand, and then bring it through the back. The accessory signal cable enables connection of two computers. (One analog and one digital connection.) · To achieve an analog and digital connection for two computers, a separately sold signal cable is required. · The separately sold 2-input cable enables connection of two computers to the DVI-I input terminal. · When using the 2-input cable, set the connecting input terminal [INPUT-1] or [INPUT-2] to [2LINES] under the MODE SELECT-1 Menu.

s Analog connection
Connect the analog signal cable to the analog RGB output terminal of the computer.

Input terminal 1 and 2 You can connect to either side.
· If the display is to be rotated, first house the cables with the display in the long height position, so there is sufficient length when the display is turned.
