Quick answer
The BenQ GW2780 uses a 100×100 mm VESA pattern (M4 screws). Screw spec: M4 metric thread. The GW2780 weighs 8.6 lb (3.9 kg) without the stand, so any arm, stand or bracket rated for 100×100 mm and at least 8.6 lb will hold it. Verified against the BenQ documentation — see source below.

Arm, stand or wall bracket for the GW2780
All three use the same 100×100 mm holes. A desk-clamp arm frees the footprint and adjusts in every axis; a freestanding VESA base replaces a wobbly factory stand; a wall bracket clears the desk but fixes the height. Whatever you pick, the rating must cover 8.6 lb — the full decision guide is VESA monitor mounts.

Double-check before buying
- Pop off any plastic caps and confirm 4 threaded holes at 100 mm across and 100 mm vertically, center-to-center.
- Check the M4 bolts seat by hand before torquing — thin monitor housings punish over-long screws.
- Compare the model code on the rear label with this page (GW2780) — same-series panels can differ.
Frequently asked questions
What VESA pattern does the BenQ GW2780 use?
The BenQ GW2780 uses a 100×100 mm VESA pattern — 100 mm between hole centers horizontally and 100 mm vertically. Any monitor arm, stand or wall bracket listing 100×100 mm fits directly. Confirm on the back of your unit, since some retail variants of a series differ.
What screws does the GW2780 need for an arm or mount?
The GW2780 takes M4 metric screws. Documented spec: M4 metric thread; length depends on the arm plate — see the manual. Most arms ship M4 hardware in two lengths — hand-test the shorter one first; a bolt that bottoms out can damage the housing.
How much does the GW2780 weigh without the stand?
The GW2780 weighs 8.6 lb (3.9 kg) without the stand. Typical desk arms list roughly 9–20 lb per screen, so check your arm's exact rating — and its supported screen-size range — against these numbers before buying.
Will a standard monitor arm hold the GW2780?
Any arm that lists the 100×100 mm pattern, carries at least 8.6 lb and covers 27-inch screens will hold it. The desk matters too: clamps need a solid edge; glass desks call for a grommet mount or freestanding base.
Can the GW2780 be wall-mounted?
Yes — the same 100×100 mm holes work on wall brackets. 3 wall mount(s) in our database clear the GW2780's 8.6 lb and 27-inch size with a 20% margin; small fixed or articulating brackets sold for compact TVs are the usual pick.
