I received this product for free from LG as part of an event. While I was asked to share my review, all opinions are entirely my own.

Hey r/LG_UserHub

I got this lovely LG UltraGear evo 39GX950B two weeks ago from LG. Here is part one of two detailing my first two weeks with this glorious display, focusing primarily on its Dual-Mode resolution shifting capability.

Unboxing and Setup: A Dreaded Greeting

The review journey started with a familiar fear. I got the knock on my door from UPS and was greeted with the dreaded question: "Do you want to refuse the package and send it back?"

My heart sank. I glanced at the massive box and saw water damage on one end (this is a fear we all have ordering anything online). I accepted the package and opened it with some relief—nothing appeared too bad, but the cardboard had started separating. Everything inside was sealed in plastic. Even though the stand and a bit of the monitor had water on the plastic covering, none touched the panel.

Setup was a breeze. The stand snaps onto the back of the panel, and the base just takes one screw. The stand doesn't occupy much desk space and is stable. It also includes new DisplayPort 2.1, HDMI 2.1, and USB-C cables, along with a cable shield. My only issue was completely rearranging my desk to support this beast, but that was worth it.

The "CRT Moment": VESA Dual-Mode (5K2K 165Hz ↔ WFHD 330Hz)

The VESA-certified dual-mode feature is the closest I’ve experienced to CRT resolution changing. Historically, buying a flat panel means committing to a native resolution; scaling causes blur and can look greasy. I typically buy a monitor my current system can support for a long time. This is why my last monitor was 1440p—I knew my system would struggle with 4K.

TheLG UltraGear evo 39GX950B removes that fear. Although my PC plays most games well, some newer titles challenge it. Dual-mode is incredible. Switching to WFHD (2560 x 1080) at 330Hz looks just like a native 1080p display, which amazed me. It doesn't look like scaled resolution.

• Forza Horizon 6 (Testing Native 5K2K): This runs at full 5K2K 165Hz for me, which is beyond gorgeous and gets about 100 FPS (with significant RAM/CPU timing optimization).
• Call of Duty: Warzone (Testing WFHD 330Hz): Warzone kills my PC at 5K2K (getting 40 to maybe 80 FPS), but switching to WFHD 330Hz holds a steady 120-150 FPS. This huge flexibility means confidence that I can play current and future games beautifully, even without top-of-the-line hardware.

Overall Experience and Gaming

Having that resolution flexibility, alongside the gorgeous 4th Gen Tandem WOLED screen and the perfect 1500R curvature, made every game immersive.

I tested several titles over the past two weeks:

• Doom Eternal & COD: Warzone (FPS/Fast Paced): As my first ultrawide, I wasn't sure I would like it in fast-paced FPS games, but my worries were unfounded.
• Elden Ring (with ultra widescreen mods) & Final Fantasy VII Rebirth (Atmospheric): Relaxing and taking in the awesome landscapes was fantastic on this display.

The Minor Niggles

In my initial time using it, I only found a few minor points that bothered me:

• Power Button Location: The multifunction power button is located where some installed cables block access. It is not huge, but you do have to push cables to reach it.
• Separate Power Button: I would prefer a dedicated on/off button instead of a multifunction switch.

Final Thoughts (For Now)

Overall, I am struggling to find things I don't love. It’s big, bright, has absolutely awesome color contrast, no motion blur, and text/images are crisp. This monitor will appeal to a wide audience—from cinematic experiences to productive real estate.

The dual-mode (5K2K / WFHD) is the trick that makes it shine among other monitors in this class. Yes, it is expensive, but you get an enormous amount of monitor. The combination of tech in this makes it the best monitor I have ever used.
