Acer Predator XB273U V3 vs Dough Spectrum One
The Dough Spectrum One 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.

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

It ships without a stand, and that is the clearest statement of intent on this page — the assumption is that you already own an arm.
Best for: A monitor-arm desk that wants 4K120 for a console and 144 Hz for a PC

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
Dough Spectrum One: what it gives up
- No stand in the box; the matching aluminium one is another $99
- 16 dimming zones is a token number — expect obvious blooming around bright objects on black
- 1000:1 native IPS contrast, so the DisplayHDR 600 badge is mostly about brightness
- No speakers and no KVM switch
- The 1 ms figure is the overdrive best case, not what the panel does with overdrive off
