Our Picks
Largest Screen1 of 5
WALI Ultrawide Single Monitor Arm (17-49 in)
WALI's ultrawide arm takes curved screens up to 49 inches and 33 lb.
Best for
- Super ultrawides.
Skip if
- Skip it if price comes first: the ErGear pole single cost less when we checked.
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.

- All 5, from the WALI ultrawide to the ErGear pole single, state screen size limit, load rating and monitors and share C-clamp or grommet mounting.
- Where the specs have gaps
- The WALI ultrawide, the HUANUO ultrawide and the ErGear single give no tension; the WALI ultrawide, the HUANUO ultrawide and the ErGear pole single give no VESA.

- From the ErGear pole single to the HUANUO ultrawide, all sat in the under $50 tier when we checked.
