LG UltraGear 45GX950A-B 44.5" Black 2025

The LG UltraGear 45GX950A-B is the world's first 5K2K OLED gaming monitor, and it's a stunner. 165Hz at 5120 x 2160, or 330Hz at Full HD in dual mode, with a 0.03ms response time and 1300 nits peak brightness. US pricing runs USD 1,500 to USD 1,800, so shop around. If you want one monitor for gaming and work, this is the one to get.

The headline numbers are wild. 330Hz in dual mode is faster than most dedicated esports monitors, and the 0.03ms response time is effectively instant. You won't see ghosting or motion blur, period. The DisplayPort 2.1 connection means you can actually push 5K2K at 165Hz without display stream compression weirdness, which has been a bottleneck on older ultrawides. FreeSync Premium Pro and G-Sync compatibility cover both GPU camps, so frame pacing stays smooth no matter what's in your rig.

Brightness hits 1300 nits peak, which is unusually high for OLED. That means HDR content actually pops instead of looking dim like it does on some OLED panels. The 98.5% DCI-P3 coverage and 10-bit color put this in the top tier for color performance, and DisplayHDR True Black 400 certifies those deep blacks OLED is known for. The 1.5M:1 contrast ratio means dark scenes in games and movies look genuinely dark, not gray. For real-world use, that translates to a monitor that's equally comfortable in a bright room or a dark one.

The ASUS ROG Strix XG27UCDMG is a 27-inch 4K OLED that's smaller and cheaper, but it can't touch the LG's 5K2K resolution or 45-inch size. If you want a desk-friendly OLED for competitive gaming, the ASUS makes more sense. The Samsung Odyssey G60SD is another 27-inch option with a 360Hz refresh rate, so it's faster in raw Hz but gives up the ultrawide immersion and resolution entirely.

The Dell UltraSharp U4025QW is the closest competitor for productivity. It's a 40-inch ultrawide with 5K2K resolution, but it's IPS, not OLED, and it tops out at 120Hz. The Dell is better for color-critical work where OLED's per-pixel lighting can cause uniformity issues, but it can't match the LG's gaming performance or contrast. The Gigabyte M Series OLED MO27U2 and MSI MPG 271QR QD-OLED are both 27-inch QD-OLED panels that compete on price and speed, but they're in a completely different category size-wise. If you want one monitor that replaces a dual-monitor setup, the LG is the only one here that actually does it.

US pricing sits between USD 1,500 and USD 1,800 across five listings. That's a USD 300 spread, so it pays to shop around. Best Buy tends to have the most consistent pricing on this one, and their price match guarantee helps if you find it cheaper elsewhere. For what you're getting, a 5K2K OLED with this refresh rate and brightness, the price is actually reasonable compared to what a comparable setup would have cost two years ago.

Canadian buyers have a rougher time. Prices range from CAD 1,900 to CAD 3,535 across six listings. That CAD 1,635 spread is brutal, and the high end is nearly double the low end. If you're in Canada, you'll want to hunt for the CAD 1,900 listings and avoid the inflated ones. Newegg's open box options sometimes show up at the lower end, which is worth watching if you're patient.

LG just dropped something that shouldn't exist yet. The UltraGear 45GX950A-B is a 45-inch curved OLED running 5120 x 2160, which is the 5K2K ultrawide resolution people have been begging for since ultrawides became a thing. And it does it at 165Hz with a 0.03ms response time. That's a spec sheet that reads like a wishlist from a PC gaming subreddit circa 2023.

This is the world's first 5K2K OLED gaming monitor, and LG didn't stop there. It has a dual mode that drops the resolution to Full HD and cranks the refresh rate to 330Hz for competitive shooters. So you get a productivity monster and an esports panel in the same chassis. The 125 PPI pixel density means text looks sharp without the color fringing that plagued earlier OLED monitors.

Who's this for? Someone who wants one monitor to do everything. Gaming, work, content creation, maybe some movie watching. The 800R curve is aggressive, so it's not for people who need a flat panel for color-critical work. But if you want immersion and you have the desk space, this is a statement piece. And at 14 kilograms, it's a statement your desk will definitely feel.

If you're a competitive esports player who only cares about frame rates, this monitor is overkill. The 45-inch size and 800R curve are actually disadvantages for competitive play, where smaller screens and flatter panels are preferred. You'd be better off with a 27-inch 360Hz panel like the Samsung Odyssey G60SD and saving a chunk of money.

If you do color-critical work like photo editing or print design, the OLED panel's per-pixel lighting and the aggressive curve will cause uniformity issues that make accurate color grading difficult. The Dell UltraSharp U4025QW is the better tool for that job. And if you're on a budget, the CAD 3,535 listings in Canada are hard to justify when the same monitor sells for CAD 1,900 elsewhere. Wait for a sale or buy from a US retailer if you can.

For gamers who also work at their desk, this is the monitor to beat. The dual mode means you can switch from a 5K2K productivity setup to a 330Hz esports panel without changing monitors. The OLED panel with 1300 nits brightness solves the biggest complaint people have about OLED monitors, which is that they're too dim for bright rooms. And the 125 PPI means text is actually readable, which has been a dealbreaker for OLED ultrawides in the past.

For pure competitive gamers, the 330Hz mode is great but the 45-inch size and 800R curve might be too much. You'd be better served by a 27-inch 360Hz panel like the Samsung G60SD. For pure productivity, the Dell U4025QW is flatter and more color-accurate. But if you want one monitor that does everything well, the LG 45GX950A-B is the first one that actually delivers on that promise.
