LG 27GX700A-B vs LG 27GX790A-B: RGB Tandem OLED Monitor Comparison Analysis
Compares and analyzes the LG 27GX700A-B and LG 27GX790A-B monitors, examining key differences such as brightness, color, and gaming performance. Analyzes the advantages and disadvantages of the new RGB tandem OLED panel and suggests which monitor is more suitable for the user.
1. 💡 Brightness Improvement and Accuracy Comparison of RGB Tandem OLED Panel
- ✅ The LG 27GX700A-B uses a new RGB tandem OLED panel to provide a 150nit brighter screen in SDR content.
- ✅ It is also 120nit brighter in HDR content, especially showing a brightness of over 1,400nit in small highlights.
- ⚠️ The LG 27GX700A-B tends to make the entire image excessively bright, prioritizing brightness.
- ✅ You can increase brightness accuracy by setting Peak Brightness to 'Low', but the highlight effect is reduced.
| 모니터 | SDR Brightness Increase | HDR Brightness Increase |
|---|---|---|
| LG 27GX700A-B | 150nit | 120nit |

2. 🌈 Color Purity and Accuracy Comparison: Advantages and Limitations of RGB Tandem OLED
- ✅ The RGB tandem OLED panel provides better color purity, and the color distinction between green and red is clearer.
- ✅ Provides slightly better color coverage in common color spaces such as DCIP3 and REC 2020.
- ✅ Vivid colors are expressed more brightly, but not as bright as QD-OLED.
- ✅ The LG 27GX700A-B has higher color accuracy before calibration in SDR, but Peak Brightness must be turned off.
- ⚠️ If Peak Brightness is turned on, the gamma is too bright and the content is displayed too brightly, so it must be corrected through calibration.

5. 🎮 Gaming Performance Comparison: Refresh Rate, VRR, Input Lag
- ✅ The LG 27GX790A-B offers a high refresh rate of 480Hz for smoother movement and clearer screen.
- ✅ Both monitors provide fast response times, maintaining clear images even in fast movements.
- ✅ Both monitors support the same VRR format to reduce screen tearing.
- ✅ Input lag is almost the same, and responsiveness is good even on consoles.
- ✅ The LG 27GX790A-B supports Display Port 2.1 bandwidth, but DSC is required for maximum refresh rate.
| 모니터 | Refresh Rate | Display Port |
|---|---|---|
| LG 27GX700A-B | 280Hz | 2.1 미지원 |
| LG 27GX790A-B | 480Hz | 2.1 지원 |
