MSI MPG 491CQP QD-OLED vs. Samsung Odyssey Neo G9: Which Ultrawide Monitor Should You Buy?
This article provides a side-by-side look at MSI's QD-OLED and Samsung's Neo G9 to help you choose the right ultrawide monitor.
Ultrawide monitors offer several advantages, including increased productivity, immersive gaming, and a more comfortable viewing experience.
If you are a gamer or a professional who multitasks a lot, you would know that working or playing games on a small screen offers a less thrilling experience and limited workspace compared to ultra-wide aspect ratios.
As two of the best ultra-wide monitors of 2025, the MSI MPG 491CQP QD-OLED and Samsung Odyssey Neo G9 are designed to bridge that gap with their expansive aspect ratios—offering a wider viewing area that lets you display more content at once, cut down on window switching, and even replace the need for a multi-monitor setup altogether.
Below, we compare both monitors based on key performance metrics to help you decide which is right for your setup.

1. Display and Resolution
Both the MSI MPG 491CQP and Samsung Odyssey Neo G9 offer a 5120x1440 resolution on a 32:9 aspect ratio, giving you the equivalent of two 1440p monitors seamlessly stitched together. Perfect for multitasking, immersive gaming, or dragging timelines in editing apps without running out of space.
Where things start to differ is in display technology. MSI uses a QD-OLED panel, which delivers richer contrast, deeper blacks, and punchier colors. The Neo G9, on the other hand, runs a VA-based Mini LED panel—still solid, but it doesn't hit the same black levels or visual depth. If you care about contrast-heavy scenes, especially in gaming or movies, MSI comes out ahead here.
2. Screen Size
There’s no real difference in size, as both monitors come in at a massive 49 inches, making them two of the largest ultra-wide options available. That said, 49 inches in a 32:9 format isn’t just big—it’s desk-dominating. If you’re upgrading, you might need to measure your workspace first.
3. Color Support
Both monitors offer over a billion colors, which is great if you’re into color grading, animation, or just want your games to look ridiculously good.
Samsung holds its ground with 99% DCI-P3 coverage, which gives it strong color accuracy right out of the box, ideal for creators who rely on consistent tones across devices.
But MSI actually goes even further here. Its QD-OLED panel achieves 98% Adobe RGB, 99% DCI-P3, and a whopping 146% sRGB. That gives it a wider overall color gamut, which translates to more vivid and saturated visuals, especially noticeable in creative work and HDR gaming.
So while Samsung is slightly more dialed-in for straight-up color accuracy, MSI gives you more range and punch, especially in content that benefits from wider color expression.
4. Panel
In terms of panel technology, MSI’s QD-OLED panel gives it a noticeable edge in picture quality. It blends the benefits of OLED’s perfect blacks and pixel-level lighting with quantum dot enhancements that boost brightness and color accuracy. This makes everything from dark movie scenes to high-contrast gaming environments feel more lifelike and immersive.
On the other hand, Samsung’s Mini LED VA panel brings better backlighting control compared to standard LED displays and holds up well in bright environments. But it doesn’t quite match the per-pixel precision or infinite contrast levels of OLED. If your setup favors deep blacks and more dynamic visuals, MSI’s panel tech is just on another level.
5. Interface & Connectivity
The MSI MPG 491CQP QD-OLED monitor offers a solid range of modern connectivity options. You get a DisplayPort 1.4a, two HDMI 2.1 ports, and a USB-C port that supports DisplayPort Alt Mode and delivers 90W power, which is clutch if you're running a laptop setup. There’s also a built-in USB hub with two USB 2.0 Type-A ports, one USB 2.0 Type-B port for upstream, and a headphone-out jack.
Meanwhile, the Samsung Odyssey Neo G9, on the other hand, steps things up with a DisplayPort 2.1, three HDMI 2.1 ports, and a faster USB hub that includes both USB 3.0 and USB 3.2 ports, giving you broader bandwidth for peripherals.
So while MSI offers a more well-rounded USB-C workflow, Samsung edges out in raw port variety and speed, especially if you're plugging in faster storage or high-bandwidth accessories.
6. Other Features
Both monitors come with a blistering 0.03ms response time—about as fast as current display tech allows, which means you’re getting instant pixel transitions and virtually no motion blur either way.
Where things split is on refresh rate: The Samsung Neo G9 pushes up to 240Hz, giving you ultra-smooth motion that’s a dream for competitive gamers running high-FPS titles.
The MSI MPG 491CQP, by contrast, taps out at 144Hz. Still plenty fluid for most users, especially if you’re more focused on visuals than maxing out frame counts.
7. Price
Pricing varies by region and sales, but in general, MSI's QD-OLED offers slightly more value for money at $799.00. It’s often priced lower than the Neo G9, despite having newer display tech. Samsung, being the long-time premium player in this space, still tends to be on the higher end of the spectrum at $1,792.35.
Conclusion
Needless to say, both the MSI MPG 491CQP QD-OLED and the Samsung Odyssey Neo G9 deliver serious ultrawide performance, but they shine in different ways.
If you prioritize visual richness, deeper blacks, and a more modern connectivity setup, MSI’s QD-OLED panel offers excellent value and striking image quality.
But if you’re a competitive gamer chasing every last frame or someone who needs the highest possible refresh rate and faster USB support, the Samsung Neo G9 gives you more power where it counts.
It all comes down to what you value more: immersion and color depth or speed and raw versatility. Either way, you're stepping into one of the best ultrawide setups available—and it's an experience that seriously upgrades how you work and play.
