Skip if

WALI Ultrawide Single Monitor Arm (17-49 in)

Why we like it

Its clamp fits desks up to 1.96 inches thick. Nothing else here matches its 49 in screen size limit; the HUANUO ultrawide comes closest at 40 in. Nothing else here matches its 33 lbs load rating; the HUANUO ultrawide comes closest at 26.4 lbs.

It also comes with a 33 lb capacity. Check the back of your monitor for a 75x75 or 100x100 VESA pattern before ordering the WALI ultrawide; curved and some slim monitors need an adapter. Confirm your desk edge fits the WALI ultrawide's clamp range and has no rear lip or drawer rail in the way. It was priced above the ErGear single and below the VIVO ultrawide single at the time of writing.
