  • Excellent ergonomic stand with full swivel, tilt, pivot, and height adjust 88th

Cons

What owners think

The Word on the Street

👍 A lot of owners are pleasantly surprised by the color quality and viewing angles, noting it's a cut above typical budget gaming panels.

The proof

Performance

What surprised us most is how well this IPS panel keeps up. You expect a 1ms response time on paper, but the G4 actually delivers it without the ugly overshoot ghosting you see on some cheaper fast monitors. The 240Hz refresh rate is the star here, and in our motion clarity tests, it sits in the 88th percentile, making fast pans and flick shots look crisp. The 400-nit brightness is solid for indoor use, and while HDR10 support is technically there, don't expect miracles. It's an SDR monitor with an HDR badge, and that's fine.

vs Competition

The G4's real fight is with the ASUS ROG Strix XG27AQDMG and the MSI MPG 271QRX QD-OLED. Those are both 1440p OLED monsters that will absolutely smoke this Samsung in picture quality and HDR. But they also cost a lot more and demand a much beefier GPU to drive. The LG UltraGear 27G810A-B is a more direct 1080p competitor, but the Samsung's ergonomic stand and slightly better color accuracy give it an edge. If your only goal is maximum frames per second on a mid-range rig, the G4 is the smarter, more focused pick.

Price

Value & Pricing

The price on this thing is all over the place, ranging from $200 to $449 depending on the vendor. At $200, it's a steal for a 240Hz IPS panel with this level of polish. At $449, you're getting into 1440p high-refresh territory, and you should probably just go buy one of those instead. If you can snag it at the lower end of that spread, it's a fantastic value for the speed you're getting.

Overview

The Samsung Odyssey G4 is the monitor you buy when you're done messing around. It's a 27-inch, 1080p, 240Hz IPS panel that's built for one thing: competitive speed. If you're a serious FPS or battle royale player who needs every frame and every millisecond to count, this thing delivers a buttery-smooth experience that feels like a genuine competitive edge. The resolution is a deliberate trade-off, keeping the pixel count low so your GPU can push those high frame rates without breaking a sweat.

Common Questions

Q: Can I adjust the height of this monitor?

Absolutely. The stand has full height adjustment, plus tilt, swivel, and even pivot for portrait mode. It's one of the best ergonomic setups you'll find on a gaming monitor at this price.

Q: How does the Auto Source Switch+ feature work?

It's a small but brilliant quality-of-life feature. When you turn on your PC or console, the monitor automatically detects the new signal and switches to that input. No more fumbling with the joystick button to cycle through HDMI 1, HDMI 2, and DisplayPort.

Q: What is the response time of this monitor?

It's rated at 1ms, and in practice, it's fast enough that you won't see any distracting ghosting or blur. Just make sure you're using the right overdrive setting in the menu, the fastest one can introduce some inverse ghosting, so stick to the middle option.

Who Should Skip This

If you're looking for a sharp, immersive display for single-player RPGs or daily productivity work, this isn't it. The 1080p resolution on a 27-inch canvas looks noticeably soft on text and fine details. Go get a 1440p monitor like the Dell UltraSharp U3225QE for work or an OLED for cinematic games instead.

Verdict

The Samsung Odyssey G4 is a single-minded speed machine. It's not trying to be a pretty 4K content creation display, and it's not pretending its HDR is anything special. It's a no-nonsense, high-refresh panel for gamers who prioritize performance over pixel density. If you're still on a 60Hz or 144Hz screen and your GPU can push 200+ frames in your favorite shooter, this is a massive, immediately noticeable upgrade that won't demolish your wallet.
