Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Its flicker performance is undocumented. Blue-light-hazard RG0 claims have commoditised across every tier, but BenQ is the only brand on this page that also cites IEEE PAR 1789 for flicker. Quntis does not. If you are flicker-sensitive, that missing test — plus BenQ's build feel — is exactly what the extra $69 buys.

■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you need a full desk lamp with adjustable arm, not a monitor-mounted barLED desk lamp verdict →
- you need a directional task lamp that reaches beyond the monitor footprint — drafting, sewing, model-making, paperwork off to the sidedesk lamps architect dossier →
- you want RGB ambient backlighting for gaming aesthetics, not task lighting
- you have a laptop without an external monitor and need portable lighting
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Quntis PRO+ is right for you
It avoids every trap below — and for just me, under $80, it is the pick because it delivers:
The clamp, not the curve
Bezel thickness is the #1 return in this category. The original BenQ ScreenBar clamps 1-3 cm (0.4-1.2 in) only, the Halo 2 spans 0.43-6 cm and the ScreenBar Pro 0.43-6.5 cm — and many 2026 ultrawides and curved flagships carry top bezels thicker than 3 cm. Measure yours front-to-back before ordering. Nothing on this page is specified for an iMac, an all-in-one, a panel with a raised centre spine on the back, or curvature tighter than 1000R.
Five bars are called ScreenBar
BenQ sells five confusable models spanning roughly $109 to $199 and the names do not signal price order: ScreenBar ($109), ScreenBar Pro ($139), ScreenBar Halo 2 ($199), plus the prior-generation ScreenBar Plus and the first-generation Halo. If the listing shows a wired desktop dial it is a Plus; if the backlight is a single zone it is a Halo 1, not a Halo 2. Match the exact model before you compare any price.
It dies when the monitor sleeps
Every bar here is USB-powered and none has a battery. Run it from the monitor's own USB port and it switches off whenever that monitor sleeps, because most consumer displays cut hub power in standby. Only the BenQ ScreenBar Pro ships its own 15 W mains adapter; everything else needs an always-on PC port or a powered hub. Check the connector too — Halo 2, ScreenBar Pro and Xiaomi are USB-C; the original ScreenBar, both Quntis bars and the Yeelight are USB-A.
