Main trade-off
LG UltraGear 27-inch QHD 240Hz
A 240Hz setting does not make games render at 240 frames per second.
Head-to-head
LG 27GR83Q vs 27GS95QE: OLED changes dark-room pictures, both keep QHD at 240Hz
The short answer
Choose the 27GR83Q-B for a work-heavy desk where static apps stay open for hours. Choose the 27GS95QE-B when dark-room games and OLED black levels are the main reason to upgrade. Both offer QHD at 240Hz, so the OLED premium is about the picture rather than more pixels or hertz.
Before you choose
The reasoning and the trade-offs
The OLED does not add refresh headroom
Both have a 4.17 ms interval at 240Hz.
What this is based on
1000 ÷ 240 = 4.17 ms. This shared interval does not mean equal pixel response or input lag.

About this comparison
Compare LG 27GR83Q-B and 27GS95QE-B for work-heavy desks and evening games. Both are QHD 240Hz, so panel use matters more than the headline.

What matters in practice
The differences that matter
The OLED does not add refresh headroom
Both have a 4.17 ms interval at 240Hz.
How we reached this conclusion
1000 ÷ 240 = 4.17 ms. This shared interval does not mean equal pixel response or input lag.
No extra native workspace is included
Both screens contain 3,686,400 physical pixels.
How we reached this conclusion
2560 × 1440 is identical. Different scaling or application settings, not the panel technology, change how much content fits.
The same number in the HDR badge means different things
DisplayHDR 400 and DisplayHDR True Black 400 are different certification labels, so comparing the number 400 alone loses the important distinction.
How we reached this conclusion
LG lists DisplayHDR 400 for the IPS model and DisplayHDR True Black 400 for the OLED model. No brightness or contrast measurement is inferred from this label comparison.
Choice A
LG, 27GR83Q-B
UltraGear 27-inch QHD 240Hz
A 240Hz IPS monitor keeps the familiar 27-inch QHD layout while giving high-frame-rate games more room to run. HDMI 2.1 makes the input specification worth checking against your graphics card.
- Best matched use
- Fast QHD games on the same screen used for work
Checked facts
- 27-inch 2560 by 1440 IPS panel at 240Hz
- HDMI 2.1 and DisplayPort inputs
- 95 percent DCI-P3 coverage and a height-adjustable pivoting stand
Choice B
LG, 27GS95QE-B
UltraGear 27-inch OLED Gaming Monitor
LG fits OLED contrast and a 240Hz QHD signal into a familiar 27-inch flat gaming monitor.
- Best matched use
- Fast 1440p gaming in a standard desk size
Checked facts
- 26.5-inch 2560 by 1440 OLED panel
- 240Hz refresh rate and 0.03ms gray-to-gray response claim
- Supports DisplayPort 1.4 and two HDMI 2.1 inputs

What changes the fit

|---|---|---|---|
| Native resolution | 2560 × 1440 | 2560 × 1440 | The OLED model does not add native detail. |
| Refresh ceiling | 240Hz | 240Hz | Both have the same maximum refresh interval. |
| Panel design | IPS LCD | OLED | Self-emissive pixels change black-level behavior and care considerations. |
| Size class | 27 inches | 27 inches | This is not a move to a larger workspace. |
| HDR tier | DisplayHDR 400 | DisplayHDR True Black 400 | These are different certification categories, not two identical HDR labels. |
| Workload fit | Static desktop work and gaming | Varied games and media | Long-lived fixed elements deserve special consideration with OLED. |
What you give up
Every choice has a cost
If you choose LG UltraGear 27-inch QHD 240Hz
- USB ports serve peripherals, not USB-C video or laptop charging.
If you choose LG UltraGear 27-inch OLED Gaming Monitor
- Sustained bright desktop pages can look dimmer than they do on a strong LCD.
What matters in practice
How to make the call
Start with the hours outside gaming
A monitor bought for games may spend far more time showing spreadsheets, browser tabs and fixed toolbars. The 27GR83Q-B is the simpler starting point for that workload. The 27GS95QE-B is more compelling when games and media dominate and you are comfortable following the OLED care guidance.
The OLED premium buys a different picture
Both monitors stop at QHD and 240Hz. The OLED's case comes from self-emissive pixels and its approach to dark content, not from a larger desktop or higher refresh ceiling. In a room and game where those picture differences matter, that can be worth paying for.
Do not reduce this to the advertised response-time number
Manufacturer response figures use specific conditions and settings. They are not directly equivalent to measured total latency or a complete motion-clarity test. Keep the recommendation tied to workload and panel design unless independent model-specific measurements are added.
What this comparison cannot tell you
- No burn-in lifespan, measured brightness or response-time advantage is quantified.
- The workload recommendation is a cautious fit judgment, not a prediction that an individual OLED will fail.
