The display refresh rate arms race continues. BOE has announced the first 600 Hertz notebook display. So far, the 480Hz option is the maximum available on some Alienware notebooks.
The refresh rate is a measure of the number of frames shown on the display per second. The higher this is, the lower the time interval (latency) between the images. Games in particular benefit from a smoother display and reduced streaking.
600 Hz further reduces latency
At 600 Hz, the latency would drop to 1.66 ms, which is only one tenth compared to a 60 Hz display with 16.66 ms. However, the absolute latency advantage is decreasing to an ever smaller extent. While the step from 60 Hz to 120 Hz resulted in a saving of around 8.3 ms, the step from 120 Hz to 240 Hz only resulted in a minus of 4.1 ms. A debate as to whether differences are still noticeable with displays with more than 240 Hz is often conducted with no clear insight.
Nevertheless, there are now desktop monitors with 360 Hz, which are primarily aimed at professional gamers with high demands. For notebooks, the industry has already moved to 480 Hz, which is available as an option on the Dell Alienware m17 R5 and Alienware x17 R2 notebooks (see cover image).
