HDR on their LG 39GX950B felt overdone and the matte coating showed on white screens.

“On LG it feels "overreacting"”

Their LG 39GX950B gets brighter than the AW3926QW but looked a little washed out next to it and flickered in black transitions.

“Noticed flickering in black transition scenes in games on the LG”

Their favourite overall, the LG 39GX950B has the brightest HDR, but the worst grey banding and some image retention between refreshes.

“the 39GX950B has the worst grey banding of the lot.”

Their open-box LG 39GX950B was excellent and very close to the AW3926QW, but they preferred glossy and returned the LG.

“The LG was excellent too.”

The 39GX950B is growing on them, but the matte coating disappoints and colour is never accurate however it's tuned.

“The 39GX950B is growing on me, but I won’t lie the matte is a bit frowny face.”

Kept the LG 39GX950B over the ASUS PG34WCDN: sharper 5K2K, much brighter HDR, useful dual mode, and a matte coating that keeps blacks deep with windows open.

“Not only did the coating not ruin it, it actually solved a problem I didn’t fully appreciate.”

The LG 39GX950B-B is the best monitor they've used; its 5K2K panel is divine and finally makes use of their RTX 5090.

“The 5K2K panel is absolutely divine and it actually drives my 9800x3d/RTX 5090 rig properly!”

Next to a first-gen Alienware 34-inch OLED, the LG 39GX950B-B has whiter whites, crisper text and felt smoother in Dune Awakening.

“Text is also a big improvement; it appears a lot crisper and easier to read.”

Their LG 39GX950B lacked the colour punch of their MSI 341CQPX until heavy tweaking, and the matte finish may make them return it.

“Even after calibration (Spyder software and tool) it’s still missing the punch of my MSI 341 CQPX QD-OLED.”

First day with the LG 39GX950B on a 5090: full DP 2.1 confirmed; AI upscaling does nothing but AI scene optimisation is kind of nice.

Three weeks with the LG 39GX950B; it barely warms up even on white screens.

Uses the LG 39GX950B for finance work by a bright window and for flight sims; the light matte coating handles reflections perfectly.

“the way LG’s matte display handles reflections is perfect for me.”

750 hours on the LG 39GX950B, mostly work in dark mode; generally great, but a game's white title has burned in faintly.

Loves their LG 39GX950B with no issues; next to an AW3926QW they couldn't get the Alienware's colours to match it.

“I currently have the LG 39" 5k2k. I love it. No issues at all.”

The LG 39GX950B caused significant eye strain within seconds, even with VRR off; they kept a Dell U4025QW instead.

Chose the LG 39GX950B over the AW3926QW for its matte coating: reflections from a nearby window are barely noticeable, banding barely visible, very bright and saturated; cabling is awkward.

“With the LG's matte coating, it’s a completely different story.”

Bought the LG 39GX950B to test while the AW3926QW was delayed and kept it; very happy with it.

“I liked the LG enough I just kept it cuz dell wasn’t really giving me a solid answer.”

Loves the LG 39-inch 5K2K; an RTX 4080 drives it well with DLSS and still gets 300+ fps in Overwatch 2.

“I'm in love with mine. I was worried after watching reviews running the 5k on my 4080, but honestly it's been great.”

Used both a Samsung G9 and the LG 39 5K2K; the LG is more immersive for gaming thanks to its height.

“The LG 39 is more immersive for gaming due to the larger vertical height.”

Ordered both LG 5K2K monitors to compare after a PG32UCDMR; recommends the 39GX950B for gaming plus productivity but kept the 45-inch, as the 39's price and AI features weren't worth it.

“In my case, I couldn't justify the 39gx950b higher price point.”

Moved from a nearly flat 34-inch to the LG 39-inch with 1500R and loves it, though they'd like a slightly stronger curve.

“I still love what I have but ya know.”

Owns the LG 39-inch 5K2K OLED and finds it great; for competitive games they'd pick 4K, and some indie games work better on a 16:9 screen.

“I really like it. I have the LG 39inch 5k2k OLED and it’s been great.”

Their LG 39GX950B has no uniformity issues; they use a separate ProArt IPS for fine sRGB colour work.

“I have the LG and it's incredible. Yes it's a little more expensive than the Dell but I have zero regrets.”

Bought the LG 39GX950B and the AW3926QW and kept the LG: its matte screen works better even in dim rooms, it is visibly brighter side by side, and it avoids the Alienware's dimming on white content such as hockey ice.

“The LG Matte screen is much better- even in dim or light controlled rooms. The Alienware really needs pitch black to shine.”
positivematte

Ordered the LG 39GX950B and the AW3926QW and returned the LG: slightly brighter, but the Alienware's colours and clarity popped more for gaming.

“I ordered both. Returned the LG. While it is a tad bit brighter.. its not a deal breaker at all”

Chose the LG 39GX950B over the Alienware and calls it the best decision: it handles the lighting in their home very well for content, games, movies and photo and video editing.

“Best decision of my life, it handles all the lighting in my house amazingly”

Recently bought the LG 39-inch 5K2K and loves it; replaced a 27-inch 1440p and 32-inch 4K pair and finds it big enough to split into two windows for work.

“I have the 39" 5K2K LG and I'm in love with it.”
positive

Found the LG UltraGear GX9 39-inch 5K2K beautiful on the desktop but unusable in games because of severe VRR flicker; turning G-Sync off fixed it, which they found unacceptable for the price.

“Until now I didn't understand the flickering people were speaking about. Holy hell...this thing was a mess!”

Saw no flicker on the LG 39GX950B but returned it because the matte coating made the image a little soft and hazy.

“I ended up returning it because the image was a little soft and hazy due to matte coating and size.”

Had the LG 39GX950B for a few days and was impressed by its brightness with no auto-dimming problems; the matte screen wasn't a big deal and colours were good after some tweaking.

“I had it for a few days and was genuinely impressed by the brightness.”

Returned the LG 39-inch three times over six months: great for gaming, but smearing in web browsing and productivity under their office lighting bothered them.

Came from an ASUS QD-OLED and finds the LG 39-inch 5K2K excellent and noticeably brighter than the Alienware; the matte coating shows only on white or very bright backgrounds.

Finds the LG 39GX950B's matte coating a bit hazier than their old 38GN950B in a bright room, and 5K2K gaming very GPU-intensive.

Tried the LG 39GX950B-B for work and wasn't impressed by its auto-brightness limiting, occasional colour fringing in Excel and burn-in risk; kept the U4025QW.

Bought the LG 39-inch 5K2K and finds it perfect; colour saturation can be tuned and they don't miss a glossy screen.

“I got the LG39, it’s perfect imo.”

Has used both the LG 39-inch 5K2K and the Alienware 39; the LG's brightness and pop in bright HDR scenes stand out, the matte finish was a non-issue, though reds looked a little off and it lacks the glossy screen's inky blacks.

On their second LG 39GX950B, the cooling fan still makes a whine that is audible at a normal sitting distance.

“This is my 2nd unit already and it does the noise. I don’t even have to put my ear next to the vent to hear it. It’s audible at a normal distance.”

Went through several LG 39GX950B and AW3926QW units and each had banding, colour uniformity problems or damage; dislikes non-QD OLED and matte coatings and is back on a PG32UCDM3.

“Either there's terrible banding on them, color uniformity issues, or the unit itself was damaged. This is between both the LG39GX950B and the AW3926QW.”
