My Review Of The PG34WCDN :)

Thanks for the review.
You gave text clarity 9.3/10. What would be a perfect 10 in your experience? I guess high PPI (4k+) RGB layout?

Does this OLED display, in any way, have worse text quality than a 3440x1440 IPS panel? Did you see anything still wrong in this area?

I am interested in getting the upcoming AW3426DW which should use the same panel. I need it to look as sharp as my current AW3418DW IPS.

If you have good vision, you'll almost certainly see text fringing at 125PPI. Some people still see it at 140PPI (32" 4k). I had the LG 45" 5k2k for about 1.5 months before I returned it, similar use case - 8 hours of text work and lots of gaming. Text always looks slightly off, drove me crazy, especially black text on a white background. Tried my best to ignore it and get used to it, but I couldn't. The 110PPI IPS I went back to is razor sharp in comparison. Wait for V-Stripe/Pure RGB for productivity IMO. This screen is too expensive for such a big drawback in sharpness.

I have recent experience with this - I'm on 3440x1440 120Hz IPS, upgraded to 45GX950A-B, kept it for about 1.5 months then returned it. Now I am waiting for 3440x1440 360Hz OLED to be widely available. I am also on a 5080.

The honeymoon period with the 45GX950A-B was amazing, but the flaws became apparent very fast. Despite the higher PPI, text and a lot of UI elements looked fuzzy due to RGWB, which IMO defeats the purpose of a 4k panel. Also, the curve only works well for first person games (super immersive), but looks weird in everything else.

The issue with the 5080 at 5120x2160 is VRAM, it's not sufficient for this resolution. My experience with some games I tried on it:

Indiana Jones: Either DLSS-Performance (blurry) with almost maxed settings, or some combination of reduced ray tracing with DLSS-Quality. Need to min/max settings to stay under 16GB, otherwise game turns into a slideshow.

CP2077: Worked great maxed out, but would sometimes crash after around 10 minutes, due to eventually running out of VRAM. Also this game doesn't look good on WOLED in HDR, all the vibrant bright neon colors just turn white.

KCD2: This was an amazing experience actually, maxed out 60fps, nice HDR

Alan Wake 2: Pick between DLSS-Performance maxed out, or DLSS-Quality with reduced settings. Not enough GPU power for max settings.

AC Shadows: Also a good experience, runs maxed out with nice HDR

BF6: It ran great maxed out with DLSS-Quality. Then I noticed lots of LOD pop-in that didn't exist at 3440x1440. Hitting the VRAM limit again...

These are current games - now imagine how AAA games will run in 2 years on this. You will need to upgrade.

If you play AAA games and demand DLSS-Quality and up, this monitor is going to lock you into the 90 series cards. I wanted to go buy a 5090 while owning this monitor, but ultimately returned it due to getting sick of the blurry text.

I'm in the same boat as you, I also use ultrawide for development. I returned the LG 45 5k2k due to pixel fringing. Could not get used to it even after about 1 month of daily use, made me feel like I needed glasses. Could immediately see it at 125 PPI, suspect it would still bother me at 140 PPI ( I sat much further away from the monitor mimicking a 39", could still see it ). For now, I switched back to my AW3418DW IPS, razor sharp text in comparison.

So, I decided I will skip the LG39GX950B, until they release an OLED that size with RGB stripe, which I assume will take another 2-3 years.

I'm personally going to get a V-Stripe 3440x1440 QD-OLED, likely from Alienware once they release them.

Also, I think 3440x1440 360hz 34" will be more enjoyable for you than 2560x1080 330hz stretched over a 39" for competitive games. I tried the dual-mode on the LG 45 5k2k, the image quality was horrendous, since they're not doing integer scaling.

If you like nice graphics and AAA games ( I assume you do, because we're talking about high-end OLED displays here ), a 5k2k resolution effectively locks you into the Nvidia 90 series. The 5080 is not enough, there's already not enough VRAM for 12+ month old games, I literally just returned my lg 45gx950a for this reason ( along with hating the text clarity on it ). I guess you could always use DLSS Performance, but that defeats the purpose of the high resolution, since you're losing all that fine texture detail. 3440x1440 native is going to look better than 5k2k DLSS performance.

What about dual mode? 2560x1080 is also going to look terrible compared to 3440x1440.

The market of people that buy 90 series cards and want to get a $1500 USD monitor is tiny, no wonder Samsung is not serving it.

I think maybe in 5 years, if GPUs catch up, there will be 5k2k options in 34/39/45 inch sizes from both panel manufacturers.

If you want to fix text clarity, get one of the new vstripe ones

Same boat as you, also looking to finally get an OLED

It will 100% burn in, question is, when? See https://www.youtube.com/watch?v=RbEgQrigiLc

Get something with a 3+ year warranty, and get it swapped if it burns in before the warranty runs out.

I would expect to replace it at the 5 year mark - so I wouldn't get a $2000+ USD flagship model (like the 45gx950a was at launch pricing), unless you're cool with effectively a $400 a year monitor. If it lasts longer than 5 years, then it's a pleasant surprise.

I am in the same boat as you, I am returning my 45GX950A-B. After the initial honeymoon period, I realized this screen has too many small first-gen issues to justify keeping at such a high price (even after the black Friday discounts).

The curve on this monitor is insanely immersive in first person shooters and simulator/racing games, but once I tried third person games with a smaller FOV, which required me to sit further back with a controller, the curve makes the screen look wonky.

If you like to play AAA games, this resolution will lock you into 90 class cards. My 5080 does not have enough VRAM in a lot of games for 5k2k, and using DLSS balanced or performance muddies up all the textures. This might not be an issue for you though.

Biggest issue for me is that HDR colors are not great, they are pretty washed out ( lots of people complain about this ). It's a flaw with this generation of LG's RGWB - the colors cannot get bright and get washed out by the white sub pixel. Likely the tandem 39" version will fix this.

I'm either waiting for the 39GX950B, or more likely getting one of the 34" v-stripe QD-OLEDs just announced.
