Encompassing Visuals
Featuring a 1800R curved design, 178° viewing angles, and 32:9 aspect ratio, the Odyssey allows you to see more at a glance. The Quantum Dot OLED panel delivers stunning images with a 1 million:1 static contrast ratio and 250-nit brightness by individually illuminating each pixel. High-dynamic range brings photos, videos, and games to life with vibrant color, bright highlights, and deep shadows. The Dynamic Black Equalizer feature analyzes the background of games and automatically adjusts the sharpness, saturation, and black details to provide you with more visibility in darkened areas.
NVIDIA G-SYNC and AMD FreeSync Premium Pro Support
With its 144 Hz refresh rate and 0.03 ms GtG response time, this 49" display provides liquid smooth graphics with competitive first-person shooters, racing sims, and other fast-paced games. At the same time, AMD FreeSync Premium Pro technology and NVIDIA G-Sync compatibility reduces screen tearing and stuttering with compatible graphics cards.

Use the Super Arena Gaming UX to quickly change your settings. You can modify the screen ratio, zoom in on the mini map, and change the picture mode to optimize specific game genres having to leave your game screen.

Rich Connectivity
Connect your device to the Odyssey QD-OLED G9 G91SD through the HDMI 2.1, DisplayPort, USB-C upstream port, and micro-HDMI ports. The Auto Source Switch+ feature detects when devices are turned on and changes to the new source signal.

Samsung QD-OLED G9 Reviews

Best electronic that I've ever invested in!

[This review was collected as part of a promotion.] High freshness rates is a good start. But the contrast and smoothness of this is magnificent! The design is very responsive and even the blackness is vibrant!

Great... until it isn't

The monitor is very clear and bright, even in well-lit rooms. Do not notice any glare or reflections unless the screen is mostly black. The curvature is nice for a screen this size. I wish it had more PBP/PIP modes so it could be set up better in my space and for games that don't play nice with the 32:9 aspect ratio. Out of the box, the monitor arm would not attach to the base, but that was a relatively easy fix. Be sure to have a friend (or a lot of open space) when unboxing, as it is quite large and heavy. After about 1 week of moderate use, a vertical green line appeared near the center of the screen. Warranty repair in progress. Assuming that goes well, I will have no complaints and will never be able to go back to multiple monitors ever again.
