The best 240Hz monitor depends on what you are optimizing for. For most PC gamers, the LG UltraGear 27GR83Q-B is the strongest all-rounder because it combines 1440p, an IPS panel, 240Hz and HDMI 2.1. For pure esports at 1080p, the Samsung Odyssey G4 25-inch is the simpler choice. If image quality matters as much as speed, the ASUS ROG Swift OLED PG27AQDM is the premium option.
| Monitor | Best for | Resolution | Panel | Refresh rate |
|---|---|---|---|---|
| LG UltraGear 27GR83Q-B | Best overall | 2560 × 1440 | IPS | 240Hz |
| Samsung Odyssey G4 25″ | Esports / easier GPU load | 1920 × 1080 | IPS | 240Hz |
| ASUS ROG Swift OLED PG27AQDM | Premium image quality | 2560 × 1440 | OLED | 240Hz |
1. LG UltraGear 27GR83Q-B: best 240Hz monitor overall
The LG 27GR83Q-B is the easiest 240Hz monitor to recommend to someone who does more than competitive shooters. LG pairs a 27-inch 2560 × 1440 IPS panel with a 240Hz refresh rate and a claimed 1ms GtG response time.
It also supports both NVIDIA G-SYNC Compatible and AMD FreeSync Premium, and LG includes two HDMI 2.1 ports plus DisplayPort. That makes it unusually flexible if your PC shares the display with a PS5 or Xbox Series X.
LG states that reaching 240Hz requires a graphics card and connection capable of DisplayPort 1.4 or HDMI 2.1.
See LG’s current 27GR83Q-B specifications.
2. Samsung Odyssey G4 25-inch: best for 1080p esports
The Samsung Odyssey G4 G40B keeps the workload lower with a 25-inch 1920 × 1080 IPS panel while still running at 240Hz. Samsung lists a 1ms GtG response-time claim, G-SYNC compatibility and FreeSync Premium.
The lower resolution is not a disadvantage if your main goal is very high frame rates in Valorant, Counter-Strike 2, Overwatch 2 or similar competitive games. It is much easier for a mid-range GPU to sustain 200–240fps at 1080p than at 1440p.
The stand is also better than many budget gaming monitors: Samsung includes height, tilt, swivel and pivot adjustment.
One correction from the old version of this guide: the G4 uses an anti-glare IPS panel; it is not a glossy-screen monitor.
See Samsung’s Odyssey G4 specifications.
3. ASUS ROG Swift OLED PG27AQDM: best premium 240Hz monitor
The ROG Swift OLED PG27AQDM is the image-quality pick. ASUS uses a 26.5-inch 2560 × 1440 OLED panel with a 240Hz refresh rate and a claimed 0.03ms GtG response time.
OLED’s near-instant pixel response and true blacks make motion and dark scenes look substantially cleaner than a typical LCD. ASUS also lists 99% DCI-P3 coverage and an anti-glare surface.
The trade-offs are price and OLED care. Static desktop elements can contribute to burn-in over very long periods, so an OLED monitor makes the most sense for someone who values gaming and media quality enough to accept the extra care.
See ASUS’s PG27AQDM specifications.
What does 240Hz actually mean?
A 240Hz display refreshes the image up to 240 times per second. That means a new refresh every 4.17 milliseconds.
| Refresh rate | Time between refreshes |
|---|---|
| 60Hz | 16.67ms |
| 144Hz | 6.94ms |
| 240Hz | 4.17ms |
The move from 60Hz to 144Hz is much larger than the move from 144Hz to 240Hz. Competitive players can still value the second jump, especially when their PC consistently produces very high frame rates, but it is not equally important for everyone.
Our 75Hz vs 144Hz vs 240Hz comparison goes deeper into the refresh-rate trade-off.
Do you need 240fps for a 240Hz monitor?
No, but the closer your game runs to 240fps, the more benefit you get from the panel’s refresh rate. A 240Hz monitor still works perfectly at lower frame rates, especially with variable refresh rate enabled.
If your GPU normally produces 90–140fps in the games you play, a 144–180Hz monitor may be a better use of the budget. If you routinely reach 200fps or more, 240Hz becomes much easier to justify.
1080p or 1440p at 240Hz?
Choose 1080p when maximum frame rate is the priority. It is easier for the GPU to drive and works particularly well around 24–25 inches.
Choose 1440p when you want better text clarity, more desktop space and sharper games while still retaining 240Hz. The trade-off is the much heavier GPU workload.
IPS, OLED or TN?
- IPS: the safest all-round choice, with good colour, wide viewing angles and fast modern panels.
- OLED: best pixel response and black levels, but more expensive and carries long-term burn-in considerations.
- TN: still used in dedicated esports monitors because of fast motion behaviour, but colour and viewing angles are weaker than IPS or OLED.
What cable do you need for 240Hz?
There is no single answer because it depends on resolution and the monitor’s ports.
For example, Samsung’s 1080p Odyssey G4 can run 240Hz over its supported DisplayPort/HDMI connections, while LG specifies DisplayPort 1.4 or HDMI 2.1 for 1440p at up to 240Hz on the 27GR83Q-B.
So do not buy a cable solely because it says “240Hz.” Check the exact resolution, refresh rate and port version supported by both your graphics card and monitor.
Can PS5 or Xbox Series X use 240Hz?
No. Current PS5 and Xbox Series X/S console output tops out at 120Hz in supported games. A 240Hz monitor can still be a good shared PC/console display, but the console itself will not use all 240 refreshes per second.
If console support matters most, our HDMI 2.1 monitor guide is the more relevant buying guide.
Which 240Hz monitor should you buy?
Choose the LG 27GR83Q-B if you want one fast monitor for gaming, general desktop use and current consoles. Choose the Samsung Odyssey G4 if your priority is 1080p competitive gaming and maximum attainable frame rate. Choose the ASUS PG27AQDM if you want OLED motion clarity and image quality and are comfortable paying more.
