LG DualUp Monitor Arm Guide: Portrait Height, VESA and Desk Clearance

The LG DualUp's unusual vertical format changes what matters in a monitor-arm setup. A compatible arm needs to meet the display's published weight and VESA requirements, but it also needs enough height, tilt control and clearance for the screen's tall footprint.

Measure the complete vertical envelope

Record the panel height, not just the diagonal measurement. Add the distance from the VESA plate to the top and bottom of the screen, then check whether the arm can place the display at your preferred eye level without the top hitting a shelf or the bottom crowding your keyboard.

Confirm VESA and bare weight

Use the current LG specification for your exact DualUp model. Compare the monitor's bare weight and VESA pattern with the exact arm's published limits. If a product page lists a range, the display must sit within that range; close-to-limit setups deserve a fit check before purchase.

Check desk and wall clearance

A tall display can need more rear travel when it tilts or rotates. Measure behind a wall-facing desk, and inspect the underside of the exact clamp position for cable trays, rear bars or drawers. A grommet or wall-mounted solution may suit some workspaces better, but only where the installation surface and product instructions allow it.

Set it up for work, not for the photo

Place the screen so your usual work area is comfortable, with the keyboard at relaxed elbow height. Use the display's full height to plan the top and bottom clearance. Keep cables routed with controlled slack through all intended arm positions.

Before ordering

1. Find the exact model's bare weight and VESA pattern.
2. Measure panel height and planned top/bottom clearance.
3. Measure desk thickness, underside clearance and rear gap.
4. Compare one exact arm's specifications.
5. Use Find My Monitor Arm if any measurement is uncertain.

How to use this guide for your own setup

Turn the specification sheet into a real compatibility check

Screen size alone does not tell you whether an arm will work. Find the monitor model on its label or manufacturer page, then write down its weight without its original stand, VESA mounting pattern, the position and depth of the VESA recess, and the dimensions of the rear housing. These details affect both the arm’s load range and the physical clearance when the screen is raised, rotated or pulled forward.

Measure the desk as well as the screen

1. Measure desktop thickness at the exact clamp position.
2. Check beneath and behind that point for drawers, cable trays, rear support bars, modesty panels and wall clearance.
3. Measure the available depth. A gas-spring arm needs room to articulate; a portrait screen can need more height and rear clearance than expected.
4. Plan the cable route with the arm at its furthest and highest position. A cable that is taut at one position can pull on a port as the arm moves.

Before you buy

Ask for the supported load range per arm, clamp and grommet requirements, VESA hardware supplied, and whether an adapter is required for your exact monitor. Do not rely on a marketplace title or an image alone: compare the listing details with the model’s official specifications. If anything is unclear, photograph the rear of the monitor and the desk edge, then use ULTI’s monitor arm finder or the monitor-and-desk fit FAQ to work through the fit before ordering.
