I had this one for productivity, and gaming, and put about 5000 hours into it. I upgraded to the 5K2K for a total of $1325 a few weeks ago. I was in the middle of playing death stranding director's cut and I didn't see much improvement from 1440p to 5K2K. Maybe its because it's an older game ¯\_(ツ)_/¯. I'm playing cyberpunk now and it's very pretty at full resolution. Hitting about 60fps with a 3080ti after following some reddit thread with recommended settings.
I did notice a serious improvement for productivity though. I was fine with the abysmal 84ppi on the 1440p now that my eyes are older but the 125ppi on the 5K2K alone was worth the upgrade.

I have this one it's not bad text wise if you are back a bit. Looks great in games but really 39" is about really the max it should be for this resolution.

Community Reviews

This 45 inch curved OLED UltraGear stands out for fast gaming, especially at 240Hz with 0.03ms response and an immersive wide format that feels great for racing and FPS play. The lower 3440 by 1440 resolution is the main tradeoff, with text looking softer at this size unless you sit back, while productivity work benefits more from the sharper 5K2K alternative. The panel is also heavy and the official stand can be awkward on smaller desks. It suits gaming first, with productivity and burn in concerns worth keeping in mind.

  • The monitor can look great in games while remaining acceptable for text when sitting farther back.

  • The curved 45-inch OLED setup can feel comfortable for immersive FPS play and sim racing sessions.

    RavenSEALlishuoxa

  • The 240Hz gaming experience can be easier to drive at 3440x1440, including when running side-by-side setups.

    Birdshtlishuoxa

  • The monitor can support productivity use with built-in auto-darkening on static images and periodic cleaning cycles.

    CleverGorilla819

  • The 45-inch QHD resolution can make desktop text look distorted for productivity workloads.

    DansDrivesm3n00b

  • The OLED panel can raise burn-in concerns for common work screens like Excel ribbon menus and grid layouts.

    awdrifter

  • The monitor can be heavy and the official stand may not fit end-to-end in tighter desk setups.

    lishuoxa

  • Support issues can be severe when ordering through LG promos, including delayed responses and delivery recalls without notification.

1440 sucks in a monitor this size, x1600 minimum IMO.

Considering a monitor 11 inches smaller has the same resolution, this would just be awful for DPI and screen clarity

Did you see any burn-in? Especially when using for productivity.

I had this monitor and sent it back. Not because it was a bad gaming monitor per say, but because when you try and use it for anything else the text looks too distorted due to the lower resolution that m3n00b mentioned. Seamonkeyminer is also correct, the text is bearable if you sit farther back, but I could never get comfortable with it. The 5k2k is the way to go IF you use this for more than gaming. For 80/20 gaming/productivity this is a good buy, for anything else I'd pass or go with a 34-39" at this resolution.

None that I could tell—it really depends on the type of productivity you're doing. Personally, I switch between macOS 'Spaces' throughout my day, and I've taken simple steps like hiding the taskbars and setting my background to black to minimize static images. The monitor itself automatically darkens when the image has been static for a while, and it enters a cleaning cycle after a few hours. I usually let it handle that when transitioning from work to play.

Thanks for the info. My work uses Excel a lot, I worry about the ribbon menu and the grid get burned in.
