Ultrawide Monitor Arm with RGB Lighting for 17 inch to 49 inch Screens
The Ergox EA-MA6112WL is built for large ultrawide and curved monitors, holding one 17–49 inch screen up to 20kg. A heavy-duty tilt pivot keeps adjustments smooth even with big, heavy displays.
Built-in RGB lighting adds ambient glow to a gaming setup, and a quick-release VESA plate makes mounting simple. Some monitors, including large Samsung ultrawides, need the VESA adaptor supplied in the monitor box. Check for it before mounting.

Frequently Asked Questions
What screen sizes does this arm support?
It is designed for screens from 17 to 49 inches, including large curved and ultrawide panels. It holds one screen at a time and fits both flat and curved displays.
What is the maximum weight it can carry?
Up to 20 kg. Weigh your monitor without its stand before ordering, and leave some headroom rather than running at the limit.
Will it fit my desk?
The desk clamp suits desktops from 10 to 85 mm thick and the grommet mount suits 10 to 48 mm. Both are installed from above the desk, so there is no need to reach underneath.
Does it need a VESA adaptor?
The arm supplies standard 75 x 75 and 100 x 100 mm mounting plates. Some Samsung monitors ship with their own VESA mounting adaptor inside the monitor box, which is easy to overlook during setup. Keep it, because the arm attaches to it. If it has been misplaced, a compatible replacement is available separately.
How does the RGB lighting work?
The arm carries RGB lighting with a mode button on the base, so you can change the effect at the arm itself. It is otherwise the same 49 inch, 20 kg gas spring arm as the non-RGB model.
