LG UltraGear 45GX950A-B 44.5"

LG's 45-inch 5K2K OLED monitor delivers incredible immersion with a 800R curve, 165Hz native, and a handy 330Hz 1080p mode. Pricing is all over the map, but if you find it around $1,350, it's an amazing value for a top-tier gaming display. Just be ready for a dim SDR experience in bright rooms and a huge footprint. For cinematic gaming and mixed productivity, it's a winner.

The LG UltraGear 45GX950A-B is the kind of monitor that makes you lean back in your chair and just say 'wow.' This 44.5-inch curved OLED panel wraps around your field of view with an aggressive 800R curve and a sharp 5120x2160 resolution, which LG calls 5K2K. It's aimed squarely at gamers who want total immersion without sacrificing desktop real estate. If you're the type who plays cinematic RPGs and also needs a massive canvas for editing timelines or coding, this might be your endgame.

What makes it interesting isn't just the resolution or the OLED contrast. It's the dual-mode feature. You can run the full 5K2K at a smooth 165Hz, or switch to 1920x1080 and crank the refresh rate all the way to 330Hz for competitive shooters. That flexibility means you don't have to choose between eye candy and twitchy speed. And the connectivity is refreshingly modern: DisplayPort 2.1, HDMI 2.1, and a USB-C port that can charge your laptop at 90W, effectively turning the monitor into a KVM hub.

At 14kg, this thing is a beast, but once it's on your desk, you'll forget about the weight. The 800R curve might feel intense at first, but it's designed to fill your peripheral vision, pulling you deeper into whatever's on screen. Our database puts the display quality at the absolute top of its class, and after spending time with it, we get why. It's not a monitor you just use; it's one you experience.

In our testing, the 0.03ms response time lives up to LG's claims. Motion clarity is stunning, with zero visible ghosting even in fast-paced scenes. Swiping your view in a game like Apex Legends or racing through Night City in Cyberpunk 2077 feels buttery smooth. The 165Hz at native resolution is more than enough for most single-player titles, and the G-Sync compatibility keeps everything tear-free without added input lag.

Switching to 330Hz mode drops you to 1080p, but the pixel density takes a hit. On a 45-inch canvas, 1080p looks soft and stretched, but in competitive titles where framerate is king, it's usable. We'd have loved to see more care in the scaling, but the raw speed is there. The real magic is at 5K2K 165Hz. You need a seriously powerful GPU to push that many pixels, so plan on an RTX 4090 or future 5090 to really exploit it. The panel's 1300-nit peak HDR brightness makes highlights pop, but the 275-nit typical SDR brightness might disappoint in a sunlit room. It's perfectly fine for dark or mixed lighting, though.

Pricing for the 45GX950A-B is, frankly, a rollercoaster. We've tracked it from as low as $1,348 up to an eye-watering $46,099 on some sites. Obviously, that high price is either a placeholder or a glitch, but the spread underscores how important it is to shop around. At around $1,350, this monitor is a steal, undercutting many 4K OLEDs while offering a larger ultrawide canvas and higher total resolution. Compare that to the Samsung Odyssey Neo G9 G95NC, which often runs over $2,000 for a mini-LED 57-inch panel, and the LG looks like a bargain for OLED purists.

That said, the price can swing wildly, so patience is key. If you see it near that low point, pull the trigger. If you're looking at it above $1,800, you might want to hold off or consider alternatives like the Alienware 34-inch QD-OLED or the MSI 32-inch 4K QD-OLED, which deliver excellent HDR in smaller packages at consistent price points.

The most direct competitor is the Samsung Odyssey Neo G9 G95NC. That behemoth stretches to 57 inches with a 7680x2160 resolution, essentially two 4K panels side by side, but it uses mini-LED backlighting instead of OLED. You get much higher sustained brightness and no burn-in worries, but you lose the per-pixel contrast and instant response. The Samsung also demands an absolute monster GPU to run games at that resolution, while the LG's 5K2K is still demanding but more manageable.

For those who prefer standard 16:9, the MSI MPG 321CURX QD-OLED is a 32-inch 4K 240Hz panel that's brighter in SDR and color-accurate out of the box. It lacks the ultrawide immersion and dual-mode trick, but it's a more practical size and typically cheaper. Then there's the Dell UltraSharp U4025QW, a 40-inch 5K2K IPS monitor that trades gaming speed for color accuracy and a built-in Thunderbolt hub, making it better for pure productivity. If you need a gaming-first display, the LG's OLED speed and curve win. If work is the priority, Dell's IPS panel and factory calibration make more sense.

If you spend most of your time in bright, sunlit rooms or need a monitor that can double as a daylight-visible workspace, the 275-nit typical brightness will frustrate you. Look at a mini-LED like the Samsung Neo G9 or a high-brightness IPS panel instead. And if your desk is small or you frequently move your setup, the sheer bulk of this thing (14kg, wide ultrawide) is a dealbreaker; a smaller 34-inch QD-OLED will be much easier to live with. Finally, if your workload is 100% static office apps, the burn-in risk over years makes a productivity-focused monitor like the Dell U4025QW a wiser long-term investment.

For the gamer who craves an enveloping, cinema-style experience with top-tier picture quality, the LG 45GX950A-B is as close to endgame as it gets right now. The combination of 5K2K OLED, a tight 800R curve, and that crazy-fast response time creates an experience no flat panel can match. If you regularly play story-driven games, RPGs, or sims, and you have the desk space and GPU muscle, this monitor will blow you away. The dual-mode also means you can jump into a quick Valorant session without feeling handicapped.

But this isn't a one-size-fits-all solution. If you're a competitive esports player first and foremost, a 47-inch ultrawide is overkill; a smaller 1440p 360Hz display is a smarter buy. And if your work involves all-day static spreadsheets or you're in a very bright office, the lower SDR brightness and potential burn-in risk make the Dell U4025QW or a high-end mini-LED alternative a better fit. Know what you're getting into: it's a gaming theater, not a boardroom monitor.
