The Ultimate 500Hz Gaming Monitor Review: ASUS XG27AQDPG vs. AORUS FO27Q5P
This video compares and analyzes two flagship gaming monitors, the ASUS XG27AQDPG and the GIGABYTE AORUS FO27Q5P. Both products use a QHD 500Hz QD-OLED panel, but differ in AC adapter, DP port version, and daisy chain support. It covers gaming performance, color gamut, HDR, screen uniformity, flicker analysis, and readability in detail, and clearly presents the advantages and disadvantages of each monitor.
1. 🔌 ASUS XG27AQDPG vs. AORUS FO27Q5P: Main Differences Compared
- ✅ ASUS XG27AQDPG: Clean installation with built-in AC adapter, DP 1.4 support
- ✅ AORUS FO27Q5P: Uses DC adapter, daisy chain function with DP 2.1 support
- ✔️ Panel performance is almost identical
| Feature | ASUS XG27AQDPG | AORUS FO27Q5P |
|---|---|---|
| Adapter Type | Built-in AC | External DC |
| DP Port | 1.4 | 2.1 (Full Bandwidth) |
| Daisy Chain | Impossible | Possible |

2. 🎮 Gaming Performance Test: Response Rate, Input Lag, 24.5-inch Mode
- ✅ Response rate and input lag are already at the highest level, so further improvements are minimal
- ✅ Possible improvements: Increased refresh rate or reduced afterimage through BFI technology
- ✅ ASUS: Improved input lag issue when using 24.5-inch mode (0.3ms difference)
- ⚠️ From the 5000 series graphics cards, you must use CRU to set custom resolutions
03:56 - 05:08
3. 🎨 Color Gamut Analysis: DCI-P3, rec.2020, Color Reproduction Rate Comparison
- ✅ 99% satisfaction based on DCI-P3, wider color gamut support based on rec.2020
- ✅ Improved color gamut accuracy in DCI-P3 mode
- ⚠️ Gigabyte: Slight decrease in color reproduction rate in DCI-P3 mode (blue area)
05:10 - 06:45
4. ⚖️ Grayscale and Brightness Test: Color Temperature, Gamma, SDR Brightness
- ✅ ASUS: Basic color temperature is slightly low, but adjustable (6500K)
- ✅ Gamma is well matched at 2.5 in the default setting
- ✅ SDR Brightness: 311cd/m² level
- ✅ SDR brightness change according to uniform brightness setting ON/OFF (up to 525cd/m²)
06:46 - 07:33
5. 🔆 HDR Brightness and Advantages of QD-OLED: Color Volume
- ✅ HDR Brightness: ASUS 950cd/m², Gigabyte 1000cd/m² or higher
- ✅ The advantage of QD-OLED is color volume, not color gamut
07:34 - 08:45
6. 🌈 Color Volume and Accuracy: Gamut Ring, DCI-P3 Mode Utilization
- ✅ Gamut Ring Measurement: Color coverage 97.4%
- ✅ Improved color accuracy in DCI-P3 mode
08:46 - 09:11
7. 🖥️ Screen Uniformity Test
- ✅ Screen uniformity is excellent due to the characteristics of OLED monitors
- ✅ ASUS: Near 1 based on 100% white
09:12 - 13:13
8. 💡 Flicker Analysis and Color Spectrum: Harmful Blue Light Reduction Effect
- ✅ Slight low-frequency flicker occurs, high-frequency flicker is a characteristic of OLED monitors
- ✅ Quantum dot technology shifts blue light wavelength, reducing harmful blue light
- ⚠️ ELMB (BFI) function only works at 240Hz, reducing brightness and increasing flicker
- ⚠️ BFI function is not good for health, so it is not recommended to use
13:14 - 14:48
9. ✨ Coating Comparison: Glossy vs. Non-Glossy, Brightness Improvement
- ✅ Previous LG panels were matte displays, this product is glossy
- ✅ Samsung QD-OLED panel: Glossy coating (Samsung's own products are non-glossy)
- ✅ Brightness improvement: Suitable for gaming at 310cd/m² level
14:49 - 15:22
10. 👓 Readability Comparison: Improved Compared to Previous Model
- ✅ Improved readability compared to previous model, especially noticeable when surfing the Internet
15:23 - 17:58
11. ⚠️ Disadvantages and Additional Information: Black Representation, DP Port Differences, Alt-Tab Delay
- ⚠️ Black appears purple in bright environments
- ✔️ DP Port: ASUS (DP 1.4), Gigabyte (DP 2.1 Full Bandwidth)
- ✔️ DSC technology is used when using DP 1.4, there is no input lag difference, but alt-tab delay exists
- ✔️ Alt-tab delay is reduced when using 5000 series graphics cards
