Why you can trust Tom's Hardware
The 49M2C8900’s comparison group is all OLED. I’ve brought in Samsung’s Odyssey OLED G9, Corsair’s Xeneon Flex, AOC’s AG456UCZD, Aorus’ CO49DQ and Asus PG49WCD. All are either 49 or 45-inch screens.
Pixel Response and Input Lag

240 Hz OLED is where it’s at and the two 144 Hz screens here are at a significant disadvantage. They will still outperform a 144 Hz LCD panel with less motion blur, but at 240 Hz, there is no blur whatsoever. The 49M2C8900 sits atop both charts with a 4ms draw time and just 22ms of total control lag. You can get a bit less lag from a 360 or 500 Hz screen, but a 240 Hz OLED has perfect motion resolution. And there is no overdrive or strobing happening. This is native performance with no tweaking required.
Test Takeaway: Perfect motion resolution means no blur. And the 49M2C8900 with its 240 Hz refresh rate delivers that. A 360 Hz OLED won’t be any smoother, it will just have a tad less input lag. At 22ms, the 49M2C8900 is more than capable of supporting the most skilled gamers. It can’t really get much better.
Viewing Angles
Viewing angles are essential for any 32:9 screen, so OLED is the most logical technology for monitors of that size and shape. The 49M2C8900 has no issues worthy of concern. The side view is slightly warmer in tone, but there is no light loss or change in gamma. The top view also retains gamma, color and brightness. You can view it from any angle, or share it, with no reduction in image quality or fidelity.
Screen Uniformity

As premium monitors, I’ve seen no uniformity issues with any of the OLEDs I’ve reviewed. That said, the 49M2C8900 is one of the very best, with zero visible hotspots in a 10% gray field pattern. There is no visible bleed or glow, and all colors are perfectly uniform from edge to edge.
