What is the last word PC gaming monitor? That’s most undoubtedly a shifting goal. 10 years in the past, for example, you in all probability would not have picked ultra-high refresh charges or OLED panels. That just wasn’t available. But right now? The answer looks an awful lot like the new LG Ultragear 45GX950A. On paper, this thing is stellar.
The basics involve a huge 45-inch OLED panel, specifically an LG WOLED as opposed to Samsung QD-OLED, the latter being essentially the only alternative OLED panel tech available for PC monitors.
LG Ultragear 45GX950A specs
Screen size: 45-inch
Resolution: 5,120 x 2,160
Brightness: 270 nits full screen, 1,300 nits peak HDR 1.5% APL
Response time: 0.03 ms GtG
Refresh rate: 165 Hz 5K2K, 330 Hz 2,560 x 1,080
HDR: DisplayHDR 400 True Black
Features: WOLED panel, dual-mode, HDMI 2.1 x2, DisplayPort 2.1, USB-C with 90W PD
Price: $1,999 | £1,849
That makes for a considerable enchancment in pixel density from about 83 DPI to roughly 124 DPI. For the document, that is nonetheless decrease than, say, a 32-inch 4K panel, which works out at 138 DPI, or a 27-inch 4K panel like the brand new Philips Evnia 27M2N3800A, which clocks in at 163 DPI. Another reference level when it comes to DPI are 27-inch 1440p panels and 34-inch ultrawides with the acquainted 3,440 by 1,440 native. Both lead to 109 DPI. As a ultimate contextual comparator right here, the pixel density on provide from this new 45-inch LG is equal to a standard 16:9 4K panel measuring 37 inches.
Anyway, the purpose right here is that this monitor gives a significant improve in pixel density for such a big show, nevertheless it does not fairly match the most well-liked 4K panel sizes in that regard. As for different specs, effectively, that is an LG WOLED panel, nevertheless it’s not the very newest era, so the full-screen brightness tops out at 275 nits versus the 300 nits-plus that a number of of the very newest OLED displays can obtain.
The headline refresh price is 165 Hz on the 5K2K native res. However, LG has additionally included quite a lot of “dual-mode” resolutions with larger refresh charges, together with a 2,560 by 1,080 mode with 330 Hz refresh. As ever, the thought is to supply the very best of each worlds, combining the element and picture precision of the complete native 5K2K with an choice to run a decrease decision at excessive body charges.
On paper, 2,560 by 1,080 gives the opportunity of integer scaling or utilizing exactly 4 pixels from a excessive decision pixel grid in a quadrant formation to behave as a single pixel in a decrease decision. But, like the various 4K displays we have examined of late that embody 1080p modes, some sort of interpolation is as an alternative getting used.
The different main spec element that is value noting is the panel curvature. It’s severely excessive at 800R. LG can also be planning an alternate mannequin primarily based on this panel with mechanically variable curvature courtesy of electrical motors. But this one has a set 800R curve. And that is an terrible lot of bend.
As for connectivity, you get twin HDMI inputs, plus DisplayPort, USB-C with 90W of energy supply and a two-port USB-A hub. Overall, it is a sturdy function set, as effectively it ought to be at this elevated value level. Not checked out the specs field but? This factor is close to two grand.
But what of the viewing and, effectively, gaming expertise? Out of the field and that is immediately a ridiculously imposing show. The mixture of the large 45-inch dimension with the 21:9 side ratio and loopy curvature makes a direct impression. Factor within the slim, symmetrical bezels on all 4 sides of the OLED panel and the general vibe is one thing alongside the traces of futuristic movie-prop.
There’s only a lack of fast ‘wow’ issue.
However, the primary impressions of the particular picture high quality are, it needs to be mentioned, a little bit of combined bag. While the pixel density is a transparent enchancment over a 3,440 by 1,440 decision 45-inch monitor, it is also simple sufficient to see on the Windows desktop that it isn’t fairly as sharp as a 32-inch or 27-inch 4K monitor.
The general degree of visible pop can also be a tiny little bit of a disappointment. LG WOLED panels from this era are inclined to have a barely inexperienced tinge that is likewise seen right here. Generally, they lack the vibrancy and, subjectively talking, the color saturation of in any other case related monitor fashions with Samsung QD-OLED panels. That’s the case with this new LG, too. There’s only a lack of a direct ‘wow’ issue.

The matte panel coating in all probability contributes to that. But the general sense of punch and vibrancy, significantly when exhibiting a vibrant picture throughout the entire display screen, is a contact underwhelming. Indeed, the general expertise may be very depending on how a lot of the panel you are lighting up.
There’s a Sony OLED demo video on YouTube exhibiting a fireworks show that appears unimaginable. Thanks to the per-pixel lighting of OLED, there is a searing precision that no LCD monitor can hope to match. Add within the big scale of the show, plus the very excessive decision, and the expertise is outstanding.
On the opposite hand, play a vibrant out of doors scene in, say, Cyberpunk 2077 and this monitor appears to be like, effectively, only a bit uninteresting. The identical can occur even on the Windows desktop. Run your PC in darkish mode with a darkish wallpaper, and this monitor can look fabulous . But as quickly as you open up a big vibrant software window, for instance a principally white webpage and the general picture dims appreciably.
You can toggle an ABL or computerized brightness limiter to forestall the dimming, however all that does is make the show dim all the time. This is an age-old OLED shortcoming at this level, nevertheless it’s somewhat extra noticeable with this era of LG OLED expertise than a typical monitor with the Samsung QD-OLED various.
While we’re with reference to relative disappointments, you possibly can instantly see on the Windows desktop that the dual-mode performance very clearly is not utilizing integer scaling. The picture high quality is somewhat mushy and a lot of the modes look fairly kludgy.
The pixel response blows away any LCD monitor and the full-screen HDR expertise when rendering principally darkish sport scenes, or certainly film scenes, may be very particular certainly.
That mentioned, the two,560 by, 1,080 330 Hz mode appears to be like cheap in video games and positively it is superior when it comes to pixel definition in comparison with utilizing GPU scaling. And you get the added bonus of 330 Hz. But it stays perplexing that, like so many different dual-mode shows, plain outdated integer scaling is not used when the numbers seemingly add as much as make it potential.
If all this sounds a little bit of a depressing moan, that is nonetheless an unimaginable show. The pixel response blows away any LCD monitor and the full-screen HDR expertise when rendering principally darkish sport scenes, or certainly film scenes, may be very particular certainly. It looks like a sneak peak of the way forward for PC show.
Buy if…
✅ You desire a massive OLED with first rate pixel density: 27-inch and 32-inch 4K panels are nonetheless sharper, however this LG remains to be an enormous advance on earlier 45-inch ultrawide OLEDs for pixel density.
Don’t purchase if…
❌ You’re anticipating a step-change in OLED efficiency: This “new” LG does not have the very newest panel tech, so full-screen brightness is a contact disappointing.
That’s the factor, nevertheless: it’s only a sneak peak. The limitations round full-screen brightness see to that, and that is not even accounting for worries over OLED burn in. In our expertise and that of most third-part assessments, burn-in is proving to be much less of a priority that we had beforehand feared, even for worst case desktop utilization.
Purely for gaming, it is in all probability not a priority in any respect, although the 45-inch diagonal and 5K2K decision are a incredible mixture for each gaming and getting severe work executed on the identical monitor.
Anyway, the general conclusion needs to be that that is not the last word gaming monitor you have been ready for. It’s very, superb by most metrics. But the full-screen brightness stays a big limitation and in the event you’re a sucker for super-tight pixel density, that side barely disappoints, too. That does not make the LG Ultragear 45GX950A unbuyable, however you do get the sensation it will be quickly overtaken by upgraded OLED expertise within the very close to future. And that is a fairly uncomfortable thought if you’re paying this a lot.
