Verdict for X-Plane 12
The LG UltraGear 45GX900A suits simmers who want more of the view out of the side windows, on a 45-inch ultrawide 3440 × 1440 OLED curved at 800R. It asks a lot of your graphics card, and at 83 pixels per inch small instrument text looks soft if you sit close.

Pros & Cons for X-Plane 12
Strengths
- The OLED panel switches each pixel off for true black, so a night approach into a lit-up city shows runway lights and city glow against a genuinely dark sky instead of the grey haze an LCD gives you.
- 240 Hz with variable refresh keeps the horizon smooth and tear-free when you bank hard in a pattern turn, and the 2-year warranty specifically covers the OLED panel.
- 3440 × 1440 is 5 million pixels, far less work than a 4K ultrawide, so a strong current graphics card with plenty of video memory can fill all 45 inches while you still run X-Plane 12's clouds and lighting up high.
Trade-offs
- OLED needs a little care on long flights: a static panel overlay, frozen G1000 screen or a parked map window left on screen for hours is exactly the kind of fixed image to avoid, so let the monitor run its pixel-refresh routines and don't leave the sim paused all day.
- At 83 pixels per inch the image is soft up close — radio frequencies and small switch labels aren't as crisp as on the higher-resolution ultrawides that cost the next step up in price, so you'll zoom the cockpit view or sit back a bit.

Frequently Asked Questions
Is this a good Monitor for X-Plane 12?
Yes — it scores 89.3/100 for X-Plane 12 and suits a simmer who wants the widest possible view from a single screen. It shines on VFR legs and night arrivals, where the 21:9 shape puts scenery in your side windows and the OLED panel gives you properly dark skies. It shows its limits on fine cockpit text, because 83 pixels per inch is soft when you lean in close.
Is it worth the price for X-Plane 12?
For the money you're choosing between a sharper flat screen and this wider, darker, faster one — and in a cockpit, view and contrast usually matter more than pixel density. If you fly mostly VFR or at night, the 45-inch curved OLED gives you something a conventional panel at the same money can't.
What graphics card does it need for X-Plane 12?
Driving 3440 × 1440 in X-Plane 12 is demanding because the sim leans hard on the graphics card, so plan on a strong current card with generous video memory. With a weaker card, drop render scaling below 100% or turn on an upscaling mode and ease back shadows and reflections before you touch texture quality.
Is the LG UltraGear 45GX900A-B 45-Inch WQHD OLED Curved Gaming Monitor, 240Hz compatible with X-Plane 12?
X-Plane 12 runs natively at ultrawide resolutions, so 3440 × 1440 fills the screen with a correct field of view and no stretching or black bars. Set the sim to the monitor's native resolution, enable G-Sync Compatible or FreeSync in your driver, and use X-Plane 12's multi-monitor window settings if you want to pop out a map or instrument panel.
How should I configure this in X-Plane 12?
Run the monitor at 3440 × 1440 and 240 Hz, with G-Sync Compatible or FreeSync switched on so the picture stays smooth when the scenery load changes. If the graphics card is struggling on approach into dense scenery, lower render scaling or enable upscaling first, then trim shadow and reflection detail.
