Running native 5k2k at 165Hz is what owners praise most: one engineer who stares at code all day said it eased years of eye strain, and another who compared it side by side with a 1440p OLED called the difference huge.

Owners keep the LG 5k2k for the combination of an ultrawide OLED at native resolution and a high refresh rate, and most who raised those points would rather run it that way than trade either.
Running native 5k2k at 165Hz is what owners praise most: one engineer who stares at code all day said it eased years of eye strain, and another who compared it side by side with a 1440p OLED called the difference huge.
Owners are divided on burn-in. Some see it as a manageable OLED trait that pixel refresh and basic habits keep in check, while others count it among the reasons they hesitate to use an OLED for long days of static work.
The LG UltraGear 45GX950A-B is a 45-inch curved OLED gaming monitor with LG's "5K2K" resolution, which is extra wide. It is for PC gamers and people who want one very wide screen in place of two monitors. It can switch between a sharp mode and a faster lower-resolution mode for gaming.

From the maker's spec page, checked October 7, 2026. A blank row means the maker does not state it.
5120 x 2160 on a 45-inch screen keeps text and images sharp, and the screen is about as wide as two normal monitors side by side. 165Hz makes motion look smooth. For fast games you can switch to 330Hz, but the picture becomes 1080p. The 90W USB-C port can carry the picture to a laptop and charge it with one cable. As an OLED, it shows very deep blacks, but its full-screen brightness is modest (275 nits), so it looks best in a room that isn't very bright.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
Once the monitor is set up, the daily habit that sticks is running it at native resolution and 165Hz. One owner tried the dual mode that trades resolution for 330Hz and simply could not bring themselves to use it; native 5k2k won. Another plays at 165Hz aiming for 120 frames and was surprised that nothing about it felt uncomfortable, aside from some flicker on inventory screens and minimaps in a few games. The 45 inch size is a point in its favour for people who found 32 inch screens too small to read, though one owner felt the curve was more than they wanted.
The adjustment several new owners had to make was around text. Two people who had just unboxed the monitor said text was harder to read than expected across Windows, Mac and Linux, even after tuning ClearType, and one said it made their eyes work harder. Only a few accounts raise this, so it is not yet clear how widely shared it is, but it is the first thing some owners noticed. An owner who briefly downsized back to a 34 inch OLED said the size was the only thing they missed.
The panel is OLED, and the reliability conversation among owners is about pixel wear rather than parts failing. The practical accounts come from people with older OLED monitors: one had a static wallpaper with white lettering and later found those pixels had worn faster, visible only on a white screen. Another, three years in and now into a fourth, spent two of those years without basic care such as hiding the taskbar, ended up with minor burn-in at the bottom that shows only in greyscale if you look for it, and said the automatic pixel refresh cycles have since made it nearly vanish.
Long-term accounts for this specific monitor are thin. Most owners writing about it had owned it for days or weeks, and the multi-year wear stories come from earlier OLED displays, not the 5k2k itself. What the accounts do agree on is the routine: hide static elements, let the pixel refresh run, and expect some wear from long static workloads. Whether the 5k2k holds up over years of eight-hour coding days is a question these owners have not yet been able to answer.

Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
33 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
The same owner, asked again at each point. Fills in as owners answer.
Two questions: how long you have had it, and anything you would like to say about it. Then we ask again as it ages. This helps our mission.

Before you buy one used, ask the seller: how old it is, whether it was ever repaired and by whom, and whether any of the parts above have been replaced. Ask to see it run. A receipt tells you the warranty start date; most makers honour the term only for the first owner.
