HDR UNDER $250

336 dimming zones and 1365 nits measured by TFTCentral, DisplayHDR 1000 certified — nothing else under $250 does local dimming at all.

✓

BLACK LEVELS

~3565:1 native contrast, rising to ~8600:1 with local dimming engaged — VA doing work no IPS panel at this price can.

✓

FAST ENOUGH TO GAME

180Hz with a measured 5.2ms G2G average at medium overdrive — fine for shooters, and honestly nowhere near the 0.03ms OLEDs two bands up.

✓

WIDE COLOUR

97.4% DCI-P3 measured — wide-gamut coverage at a price where sRGB-only panels are the norm.

✓

A LIVE LISTING

$229.99 standing price with $20 of headroom, and it is the in-stock replacement for a pick that went unavailable — three of the ten picks on the July version of this list did.

■ The catch — co-equal billing, always

336 zones is a third of what the good mini LEDs carry. Haloes around small bright objects — subtitles, a cursor, HUD elements on black — are visible where the 1152-zone Acer's are not; the VA panel's higher native contrast only partly hides it. Connectivity is bare, too: no USB hub and no USB-C, so nothing docks to it and nothing charges from it.

Dealbreaker? Runner-up №1 adds 4K, 120Hz and 65W USB-C charging for $50 more ↓

Runners-up — if your needs differ

Desktop text matters morethan HDR and 180Hz

Dell S2725QC27-inch 4K at 120Hz with 65W USB-C and a pop-down hub — the productivity answer at this money, and 163 PPI instead of 109.

You want 21:9 widthand will feed it DisplayPort

AOC CU34G4H34-inch 3440×1440 at 200Hz, 1500R curved, for $22 more — but 200Hz is DisplayPort-only and the HDMI inputs cap this panel at 100Hz.

Traps — this verdict avoids

Why the AOC Q27G3XMN is right for you

It avoids every trap below — and for just me, under $250, it is the pick because it delivers:

HDR under $250 Black levels Fast enough to game Wide colour A live listing

Trap 01

The suffix is the monitor

One character changes the panel. Dell S2725QC is 4K with USB-C, S2725QS is the same 4K panel without it, S2725DC is 1440p. Acer's XV325QK V3 has the mini-LED backlight; the plain XV325QK has none. Gigabyte sells M27Q, M27Q X and M27Q P. Confirm the full model string on the listing, not the family name.

Trap 02

"HDR Ready" is not HDR

A label without VESA certification or dimming zones does nothing — the Gigabyte M27Q X and AOC CU34G4H both carry one. DisplayHDR 400 on an IPS panel with no local dimming is SDR with a metadata tag. Real HDR here means DisplayHDR 1000/1400 with mini-LED zones, or True Black 400 on OLED — and zone count decides blooming: 336 vs 1152 is a visible difference.

Trap 03

The port has to carry the number

The advertised spec is a cable spec. The AOC CU34G4H hits 200Hz only over DisplayPort — its HDMI inputs cap at 100Hz at 3440×1440. 4K at 160Hz needs DP 1.4 with DSC or a full 48 Gbps HDMI 2.1 port, plus roughly an RTX 4070 / RX 7800 XT to feed it. And USB-C on these picks runs 15W to 96W — only 60W+ charges a laptop.
