Interface Installation

IMPORTANT ! : If the display hole pattern size is 100mm x 100mm, 200mm x 200mm or 100mm x 200mm, the display can be mounted directly to the faceplate and the interface bracket DOES NOT need to be installed! Proceed to Installing Display without Interface Bracket section.

Lay display face down on protective surface. CAUTION: Using screws of improper diameter may damage your display! Proper screws will easily thread into display mounting holes.
Select screw diameter by examining hardware (A-D) (4mm, 5mm, 6mm or 8mm) and comparing with mounting holes on display. (See Figure 20)
Select spacers: (See Figure 20)
• If mounting holes are not recessed and both uprights (P and Q) can lay flat against display, then no spacers are required.
• If mounting holes are recessed, or if protrusions prevent uprights (P and Q) from laying flat, then spacers (E1 or E2) must be used.
CAUTION: Using screws of improper length may damage your display! Proper screws will have adequate thread engagement without contacting bottom of display mounting holes.
Select screw length: (See Figure 20)
• Using your hand, insert SHORTEST length screw of selected diameter (A1, B1,C1 or D1) through universal washer (E4), bracket (P or Q), selected spacer (E1 or E2, if required), into display mounting hole. Do NOT thread screw into hole at this time.
NOTE: Universal washers (E4) are not needed if using M8 button head cap screws (D).
• Proper screw length requires base of screw head to protrude above flat washer a distance equal to or greater than the screw diameter. If screw length is inadequate, select longer screw. Select shortest screw which will protrude the required distance.
Place uprights (P and Q) on display, ensuring: (See Figure 21)
• Center of uprights (P and Q) are as close to the center of the back of display as possible after being installed. Center of bracket is indicated by the diamond-shaped hole.
NOTE: If installing to a display with a narrow hole mounting pattern, reverse uprights (P and Q) so that the upright legs do not overlap onto each other. (See Figure 21)

6. Using Phillips screwdriver, carefully install selected screws through universal washers (E4, if required), uprights (P and Q), and spacers (E1 or E2, if required), into display. (See Figure 20)

7. Tighten all screws. Ensure all applicable display mounting holes (4, 6, or 8) are used.

8. Connect top interface support (R) to uprights (P and Q) using four #10-24 x 1/2″ button head cap screws (W). (See Figure 22)

NOTE: If possible install screws diagonally across from each other in order to provide maximum support in Steps 8 and 9.

9. Connect bottom interface support (S) to uprights (P and Q) using four

10-24 x 1/2″ button head cap screws (W). (See Figure 22)

10. When connecting bottom interface support to uprights, make sure that it is aligned vertically with top interface support. (See Figure 22)

Install Display to Wall Plate

Using Interface Bracket

WARNING: Exceeding the weight capacity can result in serious personal injury or damage to equipment! It is the installer’s responsibility to make sure the combined weight of all components attached does not exceed 75 lbs (34 kg). Use with products heavier than the maximum weight indicated may result in collapse of the mount and its accessories causing possible injury.

WARNING : Display may be very heavy! Ensure display can be safely lifted and maneuvered as required to install on wall plate. Failure to take adequate precautions can result in serious personal injury or damage to equipment!

1. Hang interface bracket and display to faceplate by placing two mounting buttons on top interface support (R) over two teardrop grooves on top of faceplate. (See Figure 23)

2. Secure interface bracket and display to faceplate by installing two 1/4-20″ flange nuts (X) onto screws on lower interface support (S). (See Figure 23)

Installing Display Without Interface Bracket (100×100, 200×200 or

200×100)

CAUTION: Using screws of improper diameter may damage your display! Proper screws will easily thread into display mounting holes.

1. Select screw diameter by examining hardware (A-D) (4mm, 5mm, 6mm or 8mm) and comparing with mounting holes on display.
CAUTION: Using screws of improper length may damage your display! Proper screws will have adequate thread
engagement without contacting bottom of display mounting holes.

2. Select screw length:
• Using your hand, insert SHORTEST length screw of selected diameter (A1, B1, C1 or D1) into display mounting hole. Do NOT thread screw into hole at this time.

3. Install two selected screws (A-D) into upper two holes on back of display. (See Figure 24) IMPORTANT ! : If using M4 or M5 screws (A or B), washer hardware (J, K and L) must be used to ensure tight fit into the faceplate holes! For M4 screws (A), use M4 washer (K) and shoulder washer (L). For M5 screws (B), use M5 washer (J) and shoulder washer (L). (See Figure 24)

4. Hang display by two screws onto faceplate through either inner or outer teardrop mounting holes. (200×200 mounting pattern shown) (See Figure 25)

5. Install two selected screws (A-D) through selected washer hardware (H,J and K, if necessary), lower holes on faceplate and into lower two holes on display. (See Figure 25)

6. Tighten all hardware to ensure display is securely mounted.

Wall Cover Installation (Dual Stud)

1. Turn wall cover (T) outward to allow outside of covers to wrap around wall rail. (See Figure 26)

2. Place wall cover (T) over wall rail. (See Figure 26)

Cable Management

1. Make all cable connections to display.
2. Open cable management covers on upper and lower swing arms by unhinging center tabs and lifting covers to the open position. (See Figure 27)

3. Route cables on top of upper arm. (See Figure 28)

4. (Optional) Use cable ties (not included) to secure cables to upper arms by threading ties around cable and through cable tie holes on arms. (See Figure 28)

5. Close upper cable management cover. (See Figure 28)

6. Route cables under lower portion of swing arm. (See Figure 28)

7. (Optional) Use cable ties (not included) to secure cables to lower arms by threading ties around cable and through cable tie holes on arms. (See Figure 28)

8. Close lower cable management cover. (See Figure 28)

Creating Space

In order to create more space between display and wall, spacers may be added.

Extend swing arms in order to gain access to the center support.
Remove flat hex-head screw holding latch to center support. (See Figure 29)
Place latch spacer (Z) behind latch and line with holes on center support. (See Figure 29)
Install #10-24 x 1 1/4″ flat hex-head screw (V) through latch and latch spacer and into holes on center support. (See Figure 29)

5. Remove 1/2″ knob assembly installed on center support. (See Figure 29)

6. Replace 1/2″ knob assembly with 1″ knob assembly (Y). (See Figure 29)

Height Adjustment

Extend swing arms in order to gain access to the center support.
Use 1/4″ hex key (BB) to adjust height adjustment screw to raise or lower mount to desired height. Turn clockwise to raise mount and counter-clockwise to lower mount. (See Figure 30)

Roll Adjustment

Loosen roll tension adjustment screw on back of faceplate to decrease roll adjustment friction. (See Figure 31)
Adjust roll position of display as desired. (See Figure 31)
Tighten roll tension adjustment screw to desired friction level. (See Figure 31)

Tilt Friction Adjustment

Tilt display forward enough to expose screws on the side of tilting mechanism. (See Figure 32)
Adjust tilt friction adjustment screw to increase or decrease tilt friction. (See Figure 32)

Lateral Shift Adjustment (Dual Stud only)

Remove wall rail covers (N) to expose lateral shift adjustment screws on wall rails.
Loosen five lateral shift adjustment screws using 3/16″ hex key (CC). (See Figure 33)
Loosen two lower lag screws securing lower rail to the wall. (See Figure 33)
Slide mount laterally to desired mounting position. (See Figure 33)
NOTE: Removing the display from the mount will make adjusting the position of the mount much easier.
Tighten two lower lag screws. (See Figure 33)
Tighten five lateral shift adjustment screws. (See Figure 33)
Reinstall wall rail covers (N).

Arm Tension Adjustment

1. Use 1/4″ hex key (BB) to adjust arm tension at any of the four arm tension adjustment points. (See Figure 34)

2. Use 9/16″ wrench to adjust arm tension directly behind faceplate. (See Figure 35)

Install Interface Bracket Adhesive Covers (Optional)

If the interface bracket was required to install display to mount, adhesive covers may be used to cover the holes on the interface bracket in order to improve the appearance.

1. Use two long adhesive strips (DD) to cover vertical uprights. (See Figure 36)
2. Use four short adhesive strips (EE) to cover horizontal upright supports. (See Figure 36)

NOTE : These strips may be cut as desired in order to fit around screws.
