LG UltraGear vs ASUS ROG Swift: Best 1440p 240Hz Monitor
For years, PC gamers had to make a brutal choice: buy an IPS panel for beautiful colors, or a TN panel for blistering fast 240Hz speeds. Today, that compromise is dead. Welcome to the golden era of OLED Gaming Monitors.
OLED technology has completely revolutionized the desk setup. Because OLED panels don’t use a backlight, each individual pixel generates its own light. When a pixel turns off, you get infinite contrast and true, absolute blacks. Combine this with a near-instantaneous 0.03ms response time, and you get the ultimate competitive advantage.
Currently, the 27-inch 1440p 240Hz market is the absolute “sweet spot” for high-end gaming, allowing your GPU to easily push maximum frame rates. The space is dominated by two legendary titans: the LG UltraGear OLED and the ASUS ROG Swift OLED. Interestingly, both displays use the exact same panel manufactured by LG Display, but they process the image completely differently. Here is our definitive breakdown of which monitor deserves a spot on your desk.
1. Spec Check: LG UltraGear vs ASUS ROG Swift
If they both use the same internal OLED glass, what justifies the price difference? It all comes down to connectivity, cooling, and calibration.
| Feature | LG UltraGear 27″ | ASUS ROG Swift 27″ |
|---|---|---|
| Resolution & Refresh | 2560 x 1440 @ 240Hz | 2560 x 1440 @ 240Hz |
| Response Time | 0.03ms (GtG) | 0.03ms (GtG) |
| HDMI Version | HDMI 2.1 (Full Console VRR) | HDMI 2.0 (Limits Consoles) |
| Brightness/Cooling | Standard Chassis | Custom Heatsink (Higher Brightness) |
| Extra Features | Includes Physical Remote Control | Aggressive ROG Aesthetic & Lighting |
2. The Open Secret: The Same LG Panel
Here is the biggest secret in the monitor industry: ASUS does not manufacture their own OLED panels. In fact, both the ASUS ROG Swift and the LG UltraGear use the exact same WOLED panel manufactured by LG Display.
However, what a brand does with that glass changes everything. LG took their panel and built a brilliant “all-rounder” multimedia monitor with perfect console compatibility. ASUS took that exact same panel, ripped the frame off, strapped a massive custom heatsink to the back of it, and cranked the voltage to achieve brighter highlights for pure PC gamers.
3. Deep Dive: ASUS ROG Swift OLED

If you play strictly on a high-end Windows PC using a DisplayPort cable, the ASUS ROG Swift (PG27AQDM) is arguably the most breathtaking 27-inch monitor ever created. Because ASUS installed a custom, fanless heatsink directly behind the OLED panel, the monitor dissipates heat much faster than the LG model.
This thermal advantage allows ASUS to aggressively push the voltage higher. The result? The ROG Swift is noticeably brighter than the LG UltraGear, particularly when playing HDR games or watching HDR movies. The highlights are blinding, and the colors pop with aggressive saturation. It is a visual masterpiece.
✓ What We Love
- Custom heatsink allows for significantly higher peak HDR brightness
- Superior text clarity compared to early OLED models
- Aggressive “gamer” aesthetic with RGB ROG logo projection
- Excellent out-of-the-box color calibration
✕ Keep in Mind
- Only features HDMI 2.0 (Not ideal for PS5 / Xbox Series X 120Hz modes)
- Noticeably more expensive than the LG variant
4. Deep Dive: LG UltraGear OLED

If you are someone who plays PC games during the day, but hooks up a PlayStation 5 or Xbox Series X to your desk at night, the LG UltraGear OLED (27GS95QE) is the undisputed champion. Why? Because LG included full-bandwidth HDMI 2.1 ports.
This allows current-gen consoles to downsample 4K signals into a flawless 1440p image while maintaining 120Hz speeds and Variable Refresh Rate (VRR). Additionally, the LG monitor includes a physical remote control in the box, allowing you to instantly switch inputs or adjust volume without reaching under the monitor to fumble with an annoying joystick.
✓ What We Love
- HDMI 2.1 makes this the ultimate PC / Console hybrid monitor
- Included physical remote control is an absolute game-changer
- Hardware-level calibration provides highly accurate studio colors
- Often cheaper than the ASUS equivalent
✕ Keep in Mind
- Auto-Dimming features (ABL) can make desktop browsing slightly dark
- Lacks the peak HDR brightness of the ASUS model
5. Mandatory Desk Upgrade: Monitor Arms
Ergotron LX Premium Monitor Arm
Both the LG and ASUS monitors suffer from the exact same design flaw: their factory stands are massive. The wide, V-shaped legs on these monitors will eat up almost a foot of your desk depth, completely ruining your mouse-pad space for low-sensitivity FPS gaming.
If you are investing in a flagship OLED, you need a flagship mount. The Ergotron LX is the industry gold standard. It uses patented constant-force spring technology to hold your expensive OLED perfectly still, allowing you to push the monitor back against the wall to reclaim your entire desk surface.
Buy Ergotron LX MountIf budget is no object and you want the absolute brightest, punchiest HDR experience in a well-lit room, the ASUS ROG Swift PG27AQDM is the clear winner due to its custom cooling heatsink.
However, if you play in a dimmer room, want to save a few hundred dollars, and need HDMI 2.1 ports to plug in your PlayStation 5 or Xbox Series X, the LG UltraGear OLED is the smartest overall purchase for a hybrid gamer.
Frequently Asked Questions (FAQ)
Will an OLED gaming monitor get burn-in?
Modern OLED gaming monitors have aggressive burn-in protection features, such as pixel cleaning cycles, subtle screen moving algorithms, and logo dimming. While burn-in is theoretically possible if you leave static UI elements (like a Windows taskbar) on the screen for thousands of hours, companies like ASUS and LG now offer robust multi-year burn-in warranties to give gamers absolute peace of mind.
Is 1440p 240Hz better than 4K 144Hz?
For competitive gamers (playing Valorant, Apex Legends, or Call of Duty), 1440p at 240Hz is vastly superior. It provides the perfect “sweet spot” of visual clarity while delivering a massive framerate advantage. 4K monitors demand too much GPU horsepower to consistently reach high frame rates in modern titles.
Do I need HDMI 2.1 for a 1440p 240Hz monitor?
If you play exclusively on PC, no. You will use the DisplayPort 1.4 connection with DSC (Display Stream Compression) to achieve the full 240Hz. However, if you plan to hook up a PlayStation 5 or Xbox Series X to the monitor, having HDMI 2.1 (like on the LG UltraGear) is crucial to unlock Variable Refresh Rate (VRR) and 120Hz console modes seamlessly.
