Watch your retinas
Get a buddy to help you move it
Don't attempt to reconfigure the led receiver or sender settings without knowing what you are doing, we don't have configuration files for this thing, if you overwrite whats there you will brick the display.

The LED Wall consists of four main components connected in the following manner.

Computer → Sender Card → Receiver Card → LED Panel

Basic PC running windows. You also will need the XMPlayer Software to control the video wall. There is a magic portion of the screen marked out on the desktop that mirrors to the video wall. Drag whatever you want to display there.

DBSTAR - DBS-HVT11IN - Sourced from Aliexpress paid for by: 3bien, DBynoe, jon, Metal_Janet, mirong & packetbob
Connects to the computer via USB (for control and settings) and DVI for video signal.
Programmed to extract a potion of the video signal and send it to the receiver cards in each display panel

DBSTAR DBS-HRV09 S
Came with the panels, preprogrammed with the correct configuration settings, we don't have the configuration file for these so don't overwrite it or you will brick the display.
This card takes the data coming in from the ethernet link and shifts it out to the shift registers in the display panel.

112×128 pixel RGB matrix panels 10-12mm pitch.
contains 56 individual 16×16 modules - 7 modules wide and 8 high
Can be mounted sideways
has 3 - 80 amp 5v power supplies
draws between 1 and 8 amps of 120v ac at full white depending on brightness level.

Plug in the cord on the left side of the screen
Boot the computer
Turn on the toggle switch beside the power cord to power up the main screen
If the screen is powered but doesnt display an image, click the shortcut on the desktop for turn screen on and press the turn screen on button (you might have to toggle it if it thinks its already on)
if the screen scaling looks off and the desktop image isn't lining up, go to display settings and set the screen to extend desktop, then back to duplicate desktop. Also check that the scaling is set to 100%
