Summary

The LG UltraGear OLED 45GX950A-B is a 45-inch 5K2K (5120x2160) WOLED gaming monitor that has earned a strong following among ultrawide enthusiasts who want the best image quality and screen real estate available. Most owners describe the upgrade as transformative — especially those coming from 1440p ultrawides — praising the sharpness, HDR performance after calibration, and deeply immersive 800R curve. The catch is that this monitor genuinely demands a top-tier GPU: most users agree you need at least a 5080 or 5090 to push 5K2K at its native 165Hz in demanding AAA titles, which makes it an expensive ecosystem commitment. Sentiment is overwhelmingly positive among those with the right hardware, while users coming from QD-OLED panels sometimes find the WOLED colors underwhelming without tuning. A small but vocal subset report intermittent fan noise from their units, while others hear nothing at all — suggesting unit-to-unit variance.

Pros

  • 5120x2160 resolution delivers a visible sharpness jump over 1440p ultrawides, with text and game detail described as 'unparalleled' by multiple owners who made the switch
  • Dual Mode allows toggling to 1080p at 330Hz, giving competitive gamers a high-refresh option on the same panel without needing a second monitor
  • HDMI 2.1 works flawlessly and is easier to cable at longer runs than DP 2.1, which has real-world issues with black screens and DSC compression at 5K2K
  • After Windows HDR calibration and color profile tuning, HDR quality is widely praised — owners report the semi-matte coating handles glare well compared to glossy QD-OLEDs in bright rooms
  • The 800R curve, while divisive on paper, wins over most skeptics in practice once they sit at the correct ~80cm viewing distance — several self-described 'curved screen haters' say they adapted quickly
  • Strong value ceiling exists: street prices have dropped to ~$1,000–$1,350 with coupons and cashback, significantly below the $2,000 MSRP launch price

Cons

  • 165Hz is a hard ceiling at native 5K2K — even a 5090 struggles to hit it natively in demanding titles like Cyberpunk 2077 with path tracing, meaning frame generation is essentially required
  • Dual Mode's 1080p fallback looks 'gross' and blurry on such a large panel — the missing 1440p mode is the most-requested feature, and its absence frustrates 4090 owners who want a performance escape valve
  • WOLED color volume in HDR is measurably behind QD-OLED competitors like the Samsung G9 and Alienware AW3225QF — users upgrading from those panels often note the LG looks duller until calibrated
  • A subset of units ship with audible fan noise — described as a slight bearing buzz from the internal cooling fan — which LG has not definitively resolved; some owners report the issue, others hear nothing
  • DisplayPort 2.1 implementation is UHBR 13.5 (54 Gbps) rather than UHBR 20 (80 Gbps), meaning the connection uses DSC compression at full resolution — a spec disappointment for a $2,000 monitor
  • The 800R fixed curve is a dealbreaker for a meaningful number of buyers who return it — those who dislike aggressive curves should wait for the bendable 45GX990A or consider the upcoming 39" model

Most Owners Who Returned It Cite the Curve — Not the Screen

The image quality gets almost universal praise, but the 800R fixed curve generates the most returns. Users who sit too far back, use it heavily for productivity, or game on non-cinematic titles find the wrap disorienting. Those who calibrate their viewing distance or primarily play immersive single-player games rarely complain.

Reddit's Verdict: An Incredible Monitor Held Back by Its Own Price Ecosystem

To actually use this monitor the way it was designed, you're looking at a 5090 + $1,300+ monitor combination. Several users note that at this GPU price point, you're getting frame-generated fps rather than native performance — a value proposition that splits the community between 'future-proofed luxury' and 'massively overpriced for what you get today.'

The Fan Noise Lottery: Some Units Hum, Some Are Silent

A recurring thread across multiple subreddits involves an audible bearing buzz from the monitor's internal fan — present on some units, completely absent on others. LG hasn't publicly acknowledged the variance. Buyers with silent setups should be aware before assuming their unit will be quiet.

I've been using the LG45GX950 for a couple of weeks myself. There's a few things I don't like about this monitor — though ultimately I'm enjoying the upgrade to 5120x2160 at 165hz! The PPI, HDR, text, and overall display quality is a massive upgrade in comparison to the previous generation 45GR95QE with its larger pixel density. I think the curve should be slightly less aggressive, for starters.

950a owner here - the -990a was announced together with the non-bendable version, so I've waited for months, until I gave up and took the latter. I wouldn't wait and continue to miss out, but buy the -950a now and, if you really can't stand it, swap it out for the bigger one later.

Just make sure that you don't turn off the monitor from the mains. It needs a soft power outage on the monitor to do OLED refresh cycles - not only the 4 hour ones, but longer maintenance calcs/refreshes as well. Turning off power from the mains can really screw this up and reduce the lifetime of the panel quite a bit.

My 5090 is pushing the LG45 to 160 frames in BL4 using 4x frame gen. Just not sure 240 is necessary.

I have the LG 5K2K and I'm using my 4090 to run it. No issues for me and 4090 handles this display really well. I get roughly 70 FPS on 2077 with DLSS Quality and Frame Gen + MAX Settings which is more than enough for me.

Bought mine on release day from LG directly with a $300 off coupon. This is a BEAST of a monitor and I'm so glad I bought it. 100% worth the money.

I'm pretty certain the bendable version was also supposed to be 165hz. The 240hz versions are coming out next year. But at this resolution you'll be hard pressed to push most games past 165 with like 4x MFG. I have a 5090 and there's very few games that I can take beyond that. But anything beyond 165, hell even beyond 120, is so hard to notice for me. I too wanted to wait for the 240hz but said fuck it and picked this up.

No I'm happy with the screen and I've got no plans to change to the 39". I quite like the bigger size now that I'm more or less used to it. I guess if the 39" has no fan it would be the option for me but not worth the hassle/money to upgrade.

Text clarity is great. Must have been the display unit. It was possibly running in dual mode (lower resolution and high refresh rate) or not set correctly at OS level.

5k2k 165hz looks better for sure. But I love how smooth my last one was at 250hz for shooters, and latency was slightly better because the resolution wasn't as taxing on my rig. So there are trade offs, but 5k2k is the new gold standard.

When I compared the 1000R 49 to the 800R 45 side by side at the correct viewing distances, I actually liked the 800R more on the 45 than the 1000R on the 49, which surprised the hell out of me.

I use a 40" 5k2k 21:9 monitor primarily for work, it's much better than a 4k monitor because of how I can put multiple items on the screen. That being said, for gaming the 4k monitor makes way more sense.

I love mine, but I also cranked the digital vibrance in the Nvidia Control Panel to 70% to make the colors match my previous Samsung G8 21:9 that had it set to 60%. Basically perfect now, so if you feel like it's too dull just crank that one setting up. If you do professional color work.. well, buy something else imo.

I am returning the 45GX950A-B. The curve is too aggressive for anything but gaming and even then it depends on which game. Too dark towards the edge/sides. Some of the functions did not work — did not ship with crosshair on/off, just off. Dual mode wigged everything out. I did enjoy the large size of it, great rez that came through on some games... but the curve kills it.

Been using this monitor since it released and honestly love it. I switch between gaming and work and I really don't understand when people complain about the curve. It's not like it's horrible or you can't see anything anymore, if anything, I like how curved this monitor is. Well worth the pick up if you're looking for a solid OLED.

I have the monitor and I hate curved screens but I took a chance. I was pleasantly surprised I liked it so much. Once you're in front of it the curve goes away. I was surprised Tim hated it so much. To each their own.

Text quality is way better than the 1440 ultrawide version but still suffers from that generation WOLED subpixel structure. YMMV, some think it is good, I think it's unacceptable for the price point though I might be in the minority. I gave it three weeks before I returned it and just kept the Alienware AW3225QF 4k 32" QD-OLED instead, which was less than half the price. Text quality was much much better.

Brother. Never trust an in-store setup. Even my UWQHD version looked much better than the Best Buy display did. It's 124 PPI. It's going to look excellent.

I've owned both a QD-OLED and now the LG 5K2K. The color volume in HDR is slightly better on the QD OLED, but basically everything else is better on the 5K2K. I also don't sit around in a pitch black room, so the semi-matte coating works really well for my use case.

Good luck getting 240 fps on this resolution. I have the 45GX9 and on this resolution even a 5090 won't get near 165 fps with some titles.

I just got a 45GX a week ago and it's been awesome. At first I thought it was way too big, felt a bit embarrassed honestly, the curve also seemed ridiculous. But after a week I'm used to it and it's actually so great. I've been playing Dota 2, Factorio, and BF6 mostly, and a good amount of programming. I'm also running a 5080 which I think pairs well with it.

Mine makes noise as well, it's annoying. It's not too loud but noticeable if you concentrate and pinpoint it in a quiet room. I do have sensitive hearing though. I searched the issue and some people have it and others don't I guess. Some returned it and got one that makes lesser noise. The picture is amazing though and fun to game with.

I bought a Datacolour Spyder Pro to calibrate my monitor. Now my monitor is running very accurate colours and brightness is set to perfect. I don't use HDR as I don't see a main benefit for it.

Recently made the same change as you from the Samsung G9 OLED. My experience is that the colours and HDR in the LG are great after calibration, for casual/gaming use. I do prefer the LG on balance but it's close. I still miss the extra width of the 49.

I did the exact same change from Samsung G9 OLED and I couldn't be happier. I'm running a 5080 so your 'never less than a 5090' claim is bogus. I had the G9 OLED with a 3080ti, upgraded to a 5080, then upgraded my monitor to the 5k2k and still have much better fps with 5k2k and 5080 than 5120x1440 with a 3080ti.

The people that glaze this monitor are coming from a shit IPS/LCD monitor and this is their first OLED so of course it's gonna be the best thing since sliced bread. Coming from a C4 48 inch, it's FAR superior in brightness, HDR, colors and GLOSSY coating. I've already said all of these things in a big write-up and people had a fit because I talked bad about a product that I spent MY money on.

I know you guys can tell a difference but for me it's almost negligible when you are comparing 2 monitors of this caliber. I have the LG 5k2k and think the picture is awesome and have 0 complaints. For reference I'm coming from the Samsung G8 4k 240hz which is also a spectacular monitor.

I went from a 4k Samsung QD OLED G8, which I had nothing but issues with in terms of the colors and HDR — either way too dark or washed out. The colors on this LG WOLED felt brighter and better for me. I even bought two of Samsungs to make sure it wasn't just the panel, couldn't stand them. I personally could not see the benefit in QD OLED vs this LG WOLED.

I have been comparing the LG 45gx950a-b with an Alienware AW3225QF 4k QD OLED 3rd gen. The HDR on the LG did look worse, however after some calibration and HDR off, it looked almost indistinguishable from the Alienware with HDR on. I had them running side by side, tested several 4K videos and photos. The semi-matte display on the LG looks very close compared to the glossy QD OLED Alienware. At least to me.

I own the PG32UCDM and the 45GX950-A-B, I like both and I do not see any noticeable issues with pixel density or text clarity. I would like higher refresh rate, 165hz is not fast enough for fast paced PvP gaming — the 'frame density' is a little low, not horrible but noticeable vs 240hz 32" given enough GPU. Using the 330hz mode the monitor is actually amazing for PvP, highly competitive at 250+ FPS at 1080p.

I might be going against the grain, but I still think 1440p 34" is the sweet spot for desk gaming, even with a 5090. Then you can have a TV separately for 4k gaming. You lose a lot of frames for the 5k and you'd lose refresh rate. The biggest issue I have with this monitor is that the 'dual mode' drops it to 1080p. If they ever change it so that it switches to 1440p, that would be when I'd pull the trigger.

This is a great monitor, I'm driving it with a 5080 to 165 frames with no issues, and I have zero regrets. I don't know how performance would be if it were a 240 hz panel, or if I would need something like a 5090, but I'm not trying to spend that kind of money, nor do I feel like I personally need to. To me this monitor is perfect.

Solid review. I love my panel but also pick up on the fan noise. It comes from the left middle top-ish side of the monitor. I logged it to LG about a month ago just to see what would happen but they have been kicking it around 'technical teams' since then. It does simply sound like a cheap fan with a slight buzzing.

I had this for a month! I loved the curve and almost everything. The software to download was awful though! It froze my computer... had to uninstall it. I returned because of my work needed more vertical pixels and 1440p wasn't cutting it. Also, I would have preferred a glossy screen.

grabbed one. been resisting for a bit as I feel the DPI is a bit low for work (currently using a U4021; 40" feels about right for 5k2k to me). But at $1000 this is more justifiable as a mostly-fun monitor.
