Diagnosis
You have correctly identified that your LG 27UL500-W is advertised as VESA compatible, but the specific mounting details are not readily apparent on the monitor itself, leading to uncertainty.
How to Fix It
Yes, the LG 27UL500-W is fully compatible with monitor arms and wall mounts that support the VESA standard. To mount it, follow these steps:
- Remove the Stand: Lay the monitor face down on a soft, protected surface. Firmly press the quick-release button on the back of the stand's neck and lift the monitor panel away from the stand base.
- Locate the Mounting Interface: On the back of the monitor panel, you will now see the four VESA mounting screw holes arranged in a square pattern.
- Confirm Specifications: The exact pattern is 100 x 100 millimeters. The monitor's weight without the stand is approximately 4.6 kg (10.1 lbs).
- Attach the Arm: Ensure your monitor arm or wall mount bracket supports the 100x100 VESA pattern and a weight capacity exceeding 4.6kg. Use the appropriate screws (typically M4), ensuring they are not so long that they penetrate and damage the monitor's internal circuitry.
If That Didn't Work
If the arm bracket does not align or fit securely:
- Double-check that you have completely detached the monitor from its original stand. The plastic neck piece from the stand must be removed to expose the full metal VESA plate.
- Verify the screw length. The correct screws must thread securely into the monitor's metal inserts without bottoming out. Screws longer than 10mm are often too long.
- Confirm your monitor arm's clamp or grommet mount is rated for a 27-inch screen and the monitor's weight. An under-rated arm may not hold the monitor stable.
Heads Up
When handling the monitor panel without its stand, always support it from the sides and avoid pressing on the screen. An assistant is recommended for the mounting process to prevent accidental drops.
