Dell is the first manufacturer to offer a laptop monitor with an ultra-high refresh rate of 480Hz, which reduces motion blur. This display option is now available on the Alienware m17 R5 and x17 R2 laptops.

480Hz displays for Alienware m17 R5 and x17 R2

The Alienware m17 R5 and Alienware x17 R2 are now also available with a 480Hz display, Dell announced.

Motion blur is further reduced

A higher refresh rate should render moving images more smoothly and reduce streaks (ghosts) more than is already the case with 240Hz or 360Hz. The time it takes to display the next image is reduced from 4.2 ms to 2.1 ms compared to 240 Hz and is therefore halved.

However, in absolute terms, the difference is minimal and discussions are likely to follow as to whether this is still noticeable. experts from bluebusterswho experimented with a prototype with 480 Hz years ago, is certain that 480 Hz visibly reduces motion blur.

In any case, the monitors set a new standard for relentless (professional) gamers. Dell is also targeting the latter:

Aspiring e-athletes especially appreciate the benefits of the ultra-high refresh rates of the 480Hz screen.


The 480Hz displays for Dell laptops offer a resolution of 1,920 x 1,080 pixels (Full HD) at 17.3″ and are limited to a response time of 3ms. However, the manufacturer is silent on the type of board (TN, IPS …). Features like AMD FreeSync, Nvidia G-Sync, and advanced Optimus technology are supported for switching from an integrated GPU to a dedicated GPU.

Probably TN panels from AUO

Even if confirmation is still pending, the screens will likely come from manufacturer AUO, which only introduced its first 480Hz panels for laptops and monitors as part of its presentation week in May. These are TN plates whose liquid crystals alternate especially quickly.
