Acer Predator XB273U V3

Name: Acer Predator XB273U V3
Brand: Acer
Price: 350 USD
Availability: InStock

Predator is Acer's gaming brand rather than a specification, and on this model the difference from the cheaper Nitro amounts to 50 more nits, a red-accented chassis and G-Sync Compatible certification on top of FreeSync Premium; the panel underneath is the same class of 27-inch 1440p IPS at 180 Hz with 0.5 ms rated response. Nothing docks to it — no USB-C and no hub — so the extra fifty dollars over the Nitro buys 50 more nits and the Nvidia certification, and nothing else.

Port speed — can each input carry this panel?

2×HDMI 2.0· below the panel's maximum
DisplayPort 1.2· below the panel's maximum

This panel needs 19.1 Gbps at 2560×1440, 180 Hz and 24 bits per pixel, with no DSC to fall back on.

Best for: An Nvidia build that wants certified G-Sync without paying for a hardware module

No input on this monitor carries 2560×1440 at 180 Hz and 24 bits per pixel at once. There is no lower bit depth to fall back to either — this is already an 8-bit panel — so the advertised refresh rate is available only at a lower resolution, or on the reduced-blanking timing a DisplayPort link can use in place of the television timing this figure assumes. How the arithmetic works.

400 nits rated brightness
95% DCI-P3 coverage
Two 2 W speakers and a headphone passthrough
Tilt, height, swivel and rotate stand

What it does well

Certified on both FreeSync Premium and G-Sync Compatible, so it behaves predictably whichever GPU it ends up behind
400 nits is 50 more than the equivalent Nitro panel and noticeably easier to read near a window
0.5 ms is the rated response, quicker on paper than the TN esports panels that used to own this specification
Two 2 W speakers and a headphone passthrough cover a console's audio without adding anything to the desk

What it gives up

No DisplayHDR certification at any tier — VESA has never listed this model — and no dimming-zone count either, so the HDR mode tone-maps onto a 400-nit edge-lit backlight
DisplayPort here is 1.2 and the HDMI ports are 2.0, so 180 Hz is available on exactly one input
1000:1 contrast is standard IPS — black levels lift visibly in a dark room

The two lists above come from the maker’s specifications and from published third-party measurements, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
