Acer Nitro XV275K V3 vs Acer Predator XB273U V3
The Acer Nitro XV275K V3 is 22 pixels per degree sharper at a desk distance — 68 against 46, and that is the line between sharp and retina-class. Every other published specification for both is in the table, with the rows where they differ tinted.

VESA DisplayHDR 1000 on a 4K 160 Hz panel at four hundred dollars is the pitch, and the certification is the evidence behind it: VESA does not award that tier without real local dimming, however many zones do the work — Acer publishes no count for this version.
Best for: HDR gaming on a budget that will not stretch to an OLED
- 2×HDMI 2.1· full speed

Acer Predator XB273U V3

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

Acer Nitro XV275K V3: what it gives up
- No USB-C input and no USB hub at all, so it docks nothing — and other versions of this model number do carry them, so check the letter
- The stand tilts and raises and nothing else — no swivel and no portrait pivot
- 16.7 million colours means an 8-bit panel, so gradients band where a 10-bit panel holds together
- Acer publishes neither a native-contrast figure nor a dimming-zone count for this version, so the HDR claim rests on the certification alone — and zone-based dimming always blooms around small bright objects
- No speakers at all — the back has a headphone jack and a line out and nothing that makes sound
Acer Predator XB273U V3: 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
