Save big on a 27-inch 4K gaming monitor that can switch to 320Hz at 1080p

f you’ve been waiting for a “buy it now” price on a serious gaming monitor, this one’s hard to ignore. The Acer Predator XB273K is down to $289.99 (was $699.99), saving you $410 (about 59% off). That’s a big cut for a 27-inch 4K IPS display, especially because this model is built for two different use cases: sharp 4K gaming and a faster mode for competitive play. If you’ve been stuck choosing between resolution and speed, this is one of the few monitors that tries to give you both in one package.

You’re getting a 27-inch 4K UHD IPS panel with FreeSync Premium and DisplayHDR 400 support. The headline spec is “up to 320Hz,” but the key detail is how it works: this is a dual refresh style monitor. You can run 4K up to 160Hz, or switch to 1080p for up to 320Hz when you want maximum responsiveness.

You also get a speed-focused spec sheet with up to 0.5ms response time claims, aimed at reducing blur and keeping motion looking clean in fast games.

At $289.99, the value is that you’re not boxed into one “monitor identity.” Want crisp single-player visuals, sharp text, and 4K detail? Run 4K at high refresh. Want to sweat in competitive shooters where frames matter more than pixels? Flip to 1080p and chase the higher refresh mode.

Just keep it real: to actually benefit from high refresh at 4K, you’ll want a strong GPU (and you may find yourself using upscaling in demanding titles). The 320Hz mode is also best for esports-style games where you can push very high frame rates.

If you want a flexible “do-it-all” gaming monitor and you’ve been waiting for a price that feels like a steal, $289.99 is a great time to jump. If you know you’ll only ever play competitive titles at 1080p, you could spend less on a dedicated high-refresh 1080p monitor. But if you want the option to go 4K for visuals and still have a 320Hz mode for speed, this deal hits a sweet spot.
