MI-3990 Full Motion TV Mount

The MI-3990 is a full motion wall bracket built for flat screens from 32 to 55 inches. Dual articulating arms support displays up to 88 lbs and fit VESA patterns between 200 x 200 and 400 x 400. A 2.1 inch profile keeps the screen close to the wall when retracted. Cable clips route cords from streaming devices or cable boxes neatly along the arms.

Upgrade from fixed or tilt-only brackets

Swapping a stationary mount for this model adds 18.3 inches of extension, 60 degrees of swivel and 15 degrees of downward tilt. The jump is worth it when seating spreads across a wide room or when glare changes through the day. Three degrees of rotation let you level the screen after installation without removing it from the wall.

Check VESA pattern and stud spacing before ordering

Verify the TV's mounting holes fall within the 200 x 200 to 400 x 400 range and that the screen weight does not exceed 88 lbs. Measure the distance between wall studs to confirm the bracket's mounting plate aligns with at least two studs. Ensure 18.3 inches of clearance in front of the wall for full extension without furniture interference.

Questions about this item

What VESA patterns and stud spacing does the MI-3990 wall plate require?

The wall plate fits VESA patterns from 200 x 200 mm up to 400 x 400 mm, so confirm your TV's mounting holes fall within that range before drilling.

How do I secure the arms so the TV stays level after setting the 18.3" extension?

Tighten the swivel and tilt tension bolts on both articulating arms after positioning; the step most installers miss is re-checking level once the TV weight settles.

When should I inspect the powder-coated steel hardware and cable clips?

Check bolts, clips and the wall anchors every six months for loosening or corrosion, especially if the mount is frequently extended to 18.3".
