Sceptre U275W‑UPT
$70 under your budget

■ The catch — co-equal billing, always
The build is where Sceptre saves money — panel uniformity and stand quality are noticeably worse than the Samsung it undercuts, there's no USB-C, and it tops out near 70Hz. Plan to VESA-mount both from day one.
Dealbreaker? The Samsung ViewFinity S70D fixes uniformity for ~$120 more a screen ↓

Bezel arithmetic
Two monitors' inner bezels stack into a single seam down the middle. Pair anything over ~8mm per side and you stare at a 12-16mm gap all day; every pick here sits at 6-8mm per side.
Mismatched pair
Mixing panel types (IPS vs VA), resolutions, or color gamuts across the two screens creates a visible brightness and color break at the seam. Buy two identical units — never one of each.
Bandwidth ceiling
Dual 4K at 120Hz needs DisplayPort 1.4 or HDMI 2.1 per monitor, and USB-C daisy chain needs Thunderbolt 3/4 or USB4 on your laptop. Older USB-C 3.2 ports quietly drop you to 4K 60Hz or force compression.
