Highlights

On the monitor display which is front facing, an aircraft is flying toward the sun over a mountain landscape. Above the monitor are two logos, demonstrating IPS panel and wide viewing angle functions.

IPS panel

A monitor which is seen from its right side shows two spaceships blasting off into space. The monitor is split in two to show the difference in display quality comparing two different refresh rates and response time, one for conventional monitor with 60Hz and 5ms and the other for Odyssey G4 with 240Hz and 1ms.

240Hz refresh rate

Two monitors show the same scene of a star ship flying over asteroids heading to an unknown world towards deep space. The left monitor's screen where G-Sync is off is disjointed with jarring screen jitter while the right with G-Sync on shows the star ship with perfect clarity.

Nvidia G-Sync compatible

Two monitors are side by side, with the left monitor rear-facing pivoted to the left showing the stand, while the right monitor is fully vertical. Above the monitor are four logos demonstrating the height adjustable stand, tilt, swivel and pivot functionalities.

I bought this monitor on prime day like a week ago for 199 euros, what a deal!! I don't think 1080p is too little for 27 inch as u don't really get to see the pixels unless you really look for them. I always used 60hz but now 240hz makes so much of a difference that really 60hz now looks laggy. Amazing picture quality with the IPS panel, I really like to see vivid colors and so I chose this monitor. The only thing wich I don't like that keeps me from putting 5 stars is the lack of speakers wich to me (I don't like using headphones) are necessary. For the rest it is a best buy

I bought the monitor from Bulgaria for this price (1080p 240hz HDR) I think it is the best choice because it also includes the (G-Sync) technology. I've been using it for 5 months and still haven't encountered any problems. I'm calling out to the people who are bad here, this choice is the best and the best quality for this price.

Nice monitor, not 1440p, 25 inch, not curved, 240FPS!!!, that is the only good thing about is as well as HDR and the menu is misleading as it says 'volume' in system when that is for headphones. Really would have liked speakers.

Samsung Odyssey G4 25BG400 Gaming Monitor Review: A 240Hz IPS Panel Powerhouse The Samsung Odyssey G4 25BG400 is a 24.5-inch gaming monitor that packs a punch with its 240Hz refresh rate and 1ms response time. This monitor is aimed at competitive gamers who prioritize smooth, tear-free gameplay and fast response times. Let's dive deep into its performance, features, and overall value. Design and Build Quality The Odyssey G4 sports a sleek, minimalist design with a predominantly black aesthetic. The bezels are slim on three sides, creating an immersive viewing experience. The monitor's stand offers decent adjustability, allowing for tilt, swivel, and height adjustments. The build quality is solid, with the monitor feeling sturdy and well-constructed. Panel and Picture Quality The Odyssey G4 utilizes an IPS panel, which is known for its excellent color accuracy and wide viewing angles. The 240Hz refresh rate and 1ms response time ensure smooth, fluid motion and minimal ghosting, making it ideal for fast-paced games. The FHD resolution (1920x1080) is sufficient for this screen size, offering a good balance of sharpness and pixel density. The monitor's color reproduction is generally good, with vibrant and accurate colors out of the box. However, some users may find the default color settings slightly oversaturated. Thankfully, the monitor offers extensive customization options, allowing you to fine-tune the picture to your liking. Features and Connectivity The Odyssey G4 is pack
