27 inch 500Hz OLED monitor for competitive play

This 27 inch OLED panel runs at 2560 x 1440 with a 500Hz refresh rate and a 0.03ms response time. It targets competitive players who need the lowest possible motion blur and input lag. FreeSync Premium Pro provides adaptive sync across the full range. The flat screen covers 99% DCI-P3 and reaches 1000 cd/m2 peak brightness.

Sustained brightness and heat management

OLED pixels emit their own light so no backlight dimming occurs during long sessions. The 1,500,000:1 contrast ratio stays constant because each pixel switches off completely. Peak brightness of 1000 cd/m2 is available for HDR highlights without a time limit. The panel maintains 99% DCI-P3 coverage at all luminance levels.

500Hz refresh rate at 1440p resolution

The single specification that decides fit is the 500Hz refresh rate paired with 2560 x 1440 resolution. Buyers who need 4K detail or a wider ultrawide format will not be served by this panel. Systems that cannot sustain high frame rates at 1440p will not use the full capability. The 0.03ms response time only matters when the GPU delivers frames at that pace.

Questions sur cet article

Does the 500 Hz OLED panel run hot or draw much power during all-day sessions?

The panel is rated at 1000 cd/m2 peak brightness with a 1,500,000:1 contrast ratio, and the OLED design means no LED backlight is present, which typically limits sustained heat output compared to high-brightness LCDs.

Which cables and GPU ports do I need to actually hit 2560 x 1440 at 500 Hz?

You need a graphics card with DisplayPort 1.4 or HDMI 2.1 output and a matching certified cable; the monitor provides two DisplayPort 1.4 and two HDMI 2.1 inputs for that connection.

Will my older GPU that only has HDMI 1.4 and DisplayPort 1.2 still drive this screen at 1440p?

Yes, the monitor will accept the signal, but the 500 Hz refresh rate requires DisplayPort 1.4 or HDMI 2.1 bandwidth; older ports will fall back to lower refresh rates at 2560 x 1440.
