5K2K Details
A 143 PPI pixel density delivers sharp visuals, including clearer in-game text, UI elements, and fine details. The high pixel density also improves clarity for text-heavy documents and web browsing.

Surround Yourself in the Action
The 1500R curved design allows you to see more at a glance while enhancing immersion.
More Room to Create
With the wide workspace, you more room to edit videos, retouch photos, and manage timelines while keeping documents, research, and multiple windows visible.
Vivid Color
Powered by RGB Tandem technology, the 39" OLED panel is factory calibrated for Delta E <2 accuracy, delivering cinematic experiences with 99.5% DCI-P3 gamut coverage. Visuals are enhanced with VESA DisplayHDR True Black 500 certified high-dynamic range with a 1.85 million:1 contrast ratio and 1500-nit peak brightness.
Adaptive Sync Technologies
AMD FreeSync and NVIDIA G-SYNC compatibility ensures tear-free, stutter-free gaming with variable refresh rate (VRR) technology. A compatible graphics card is required.
AI Upscaling
AI Upscaling sharpens textures and edges of lower resolution content, making it easier to spot targets in complex environments. The technology analyzes the source signal to improve visual clarity, so no GPU upgrade is needed.
AI Scene Optimization
AI Scene Optimization adjusts brightness, contrast, and color temperature in real-time by detecting what's on screen, enhancing visibility in poorly-lit interiors and reducing overexposure in bright outdoor areas. It also helps to optimize preset modes such as Office, Animation, Movie, Game, and Sports to optimize the display.
AI Sound Enhancement
AI Sound separates voices from effects and background so footsteps and dialogue stay clear, with leveled peaks for a more balanced mix.
Amped Up Gaming Audio
The built-in 7W stereo speaker system is designed to deliver rich audio. The 4-pole headphone jack combines stereo audio and mic input, delivering crisp sound and clear game-play comms through a single connection.

I’m obsessed with this monitor!

[This review was collected as part of a promotion.] I’ve been using the EVO GX9 5K2K OLED Gaming Monitor for about a week now and I’ve honestly been loving it. The picture quality looks amazing, games feel super immersive, and the ultra wide screen has been great for both gaming and everyday use.

[This review was collected as part of a promotion.] In my first few days of using this monitor, I have been nothing but impressed so far. I game a lot and also consume media content and the OLED panel and size is truly immersive. This monitor is the sweet point of not being overwhelming big, but still looking massive. I could not recommend this product anymore! Review submitted as part of a program that provides a purchase discount.
