Please space the displays 0.5 mm apart.

Q6 When using the Multi-Screen Setting with multiple displays, how much space does there need to be around the displays? LFV70 LFV60 LFV6
LFV8 LFV50 LFV5

Leave at least 100 mm of space above, below, and to the left and right, and at least 150 mm behind the displays.

Q7 When I turn the power on for multiple displays, one or more of the displays does not start up. LFV70 LFV60 LFV6
LFV8 LFV50 LFV5

In some cases, when powering multiple displays simultaneously, one or more of the displays does not start up because of insufficient power supply.
To address this, use the "Power on Screen Delay" (for the LFV8 Series or LFV50/5 Series, "Power on Delay") function to set the timing of power supply delivery to each display separately.

• Configuring settings with the LFV70 Series or LFV60/6 Series

Remote control SETUP button → On Initial Settings menu, page 1 of 2, select "Power ON Operation: Delay" and set to "Auto" or freely set delay timing.

* When set to "Auto," the delay timing is determined automatically. It is determined by multiplying the ID number set as displayID by 0.3 seconds.
Ex.: When displayID is set to 3: 0.9 seconds
       When displayID is set to 10: 3 seconds

• Configuring settings with the LFV8 Series

Set Remote Control "MENU""Normal Setting""Power ON Delay" to the desired delay time.

• Configuring settings with the LFV50/5 Series

Remote control MENU button → On Advanced Settings 2 menu, select "Power on Delay" and freely set delay timing.

Q8 When using the Multi-Screen Setting with multiple displays, what should the surrounding temperature be? LFV70 LFV60 LFV6

The setting method for the LFV8 Series is different from that of the LFV70 Series, LFV60/6 Series, and LFV50/5 Series.

• LFV8 Series

• For DisplayPort connection
HDCP: Up to 8 displays, Non-HDCP: Up to 25 displays

• For DVI-D, VGA connection
HDCP: Up to 8 displays, Non-HDCP: Up to 10 displays

* The number of connectable displays may be limited depending on the cables, signals, and the devices that are used.

• LFV70 Series, LFV60/6 Series, and LFV50/5 Series

Up to 10 displays can be connected, but the number of displays that will function properly in a daisy-chain connection may be smaller depending on the devices used.
With an HDCP signal input, the maximum number is eight.
However, in practice the maximum number of displays varies depending on devices used, etc.

Q10 When displaying a single picture large, on a two-screen multi-display (either two across or two down), how is the picture displayed? LFV70 LFV60 LFV6
LFV8 LFV50 LFV5

With two displays side by side the picture is stretched horizontally, and with two displays, one on top of the other, the picture is stretched vertically.
If you are planning to display the picture in this fashion, it is necessary to prepare content that fits the screen aspect.
