The main difference between the AOC Agon PRO AG276QZD2 and the LG 27GS95QE-B lies in the screen technology and certain technical features.

- The AOC AG276QZD2 uses a 26.7-inch QD-OLED panel with WQHD resolution (2560 x 1440 pixels) and a very high refresh rate of 240 Hz, offering extremely fast response times (0.03 ms GtG) and infinite contrast thanks to OLED technology. It is VESA DisplayHDR True Black 400 certified, with wide colour space coverage (DCI-P3 99%, Adobe RGB 98%) and features Adaptive Sync to eliminate image tearing. It also has an integrated USB hub, speakers and several video connections (DisplayPort 1.4, HDMI 2.0 x2).

- The LG 27GS95QE-B, although not detailed in the results provided, is known to be a 27-inch OLED monitor too, but with 4K UHD resolution (3840 x 2160 pixels) and a refresh rate of 160 Hz. It offers very high image quality with a higher resolution, but a lower refresh rate than the AOC. It is also gaming-oriented with OLED characteristics, but with a stronger focus on 4K resolution than on extreme frequency.

In short, AOC favours a very high refresh rate (240 Hz) in QHD for competitive gaming with excellent responsivenessLG, on the other hand, relies on 4K UHD resolution with a more moderate refresh rate (160 Hz), offering a more detailed but less fluid image for very fast games. The choice will therefore depend on the priority between extreme fluidity and maximum resolution.
