Prime Day 2025 is almost over, but the monitor deals? They’re still going strong — and in some cases, even better than what we saw earlier this week. If you’ve been thinking about upgrading your display for gaming, creative work, or just a sharper work-from-home setup, now’s the time to move. These are some of the best prices I’ve seen all year.

We’re talking 4K OLEDs, ultrawides, and lightning-fast 360Hz displays — all heavily discounted. One of the standout deals? The Sony Inzone M9 II, now just $759. It’s a fantastic 4K monitor with gorgeous HDR and low latency, making it perfect for both PS5 and PC gaming.

Prefer speed over resolution? The Alienware AW2725QF has dropped by over $100, delivering 360Hz refresh rates and support for both 4K and 1080p — ideal for competitive players who want every edge possible.

If you’re in the U.K., there are great deals there too — no FOMO required.

Whether you’re pairing one of these with a new gaming PC or just want to upgrade your current setup, these are the monitor deals to beat. But act fast — Prime Day ends tonight, and these prices won’t hang around.
