We have tested or reviewed dozens of 24” 144Hz TN models. Pretty much without exception, these all use the same panel or a close variant of it – a panel first released back in 2011. The AOC G2590PX uses a newer panel, with marginally larger 24.5” screen size. We feel this refresh is long overdue and never would have thought the older panel would have seen action for this long. We put this monitor and novel panel through its paces in our usual gauntlet of tests, to see how it stacks up against models using the older panel variant.
The monitor uses a 24.5” 144Hz TN panel from AUO. A slight difference compared to the older panel is that this is native 144Hz rather than 120Hz overclocked to reach 144Hz. The panel supports 8-bit colour via the usual 6-bit + FRC dithering. The specified grey to grey response time is (6-bit + FRC dithering) and has a specified grey to grey response time of 1ms specified response time. As usual, don’t take this figure too seriously. Some of the key ‘talking points’ of the monitor have been highlighted in blue below.
