You no longer have to decide between 4K or 144Hz, Acer has announced 2 monitors that are capable of these specifications, one using the Nvidia G-Sync technology and the other AMD Freesync.

Predator XB273K

The new Predator XB273K gaming monitor is for gamers looking for an incredible gaming
experience. It brings games to life in ultra-high definition (3840×2160) immersion and features a
rapid 144Hz refresh rate that provides wonderfully smooth images and tear-free gameplay when
fast-moving objects buzz across the screen. NVIDIA® G-SYNC™ eliminates screen tearing by
adapting to the framerate of the outputting device, resulting in buttery smooth gameplay that
offers an unparalleled gaming experience. The IPS3 display panel features a wide colour gamut of
90% of the DCI-P3 colour space for vibrant colours that pop out and deeper blacks. For enhanced
2 colour vibrancy, VESA Display HDR 400 certification ensures better contrast and colour accuracy so
customers experience AAA games as they were meant to be.

Acer Nitro XV273K Monitor

The Acer Nitro XV273K Monitor is largely the same offing 3840×2160 at a rapid 144Hz refresh rate while minimising tears and stutters using AMD Freesync.

Nitro series monitors will all feature AMD's FreeSync technology, with Acer maintaining their Predator brand for their G-Sync complaint counterparts. The flagship of this new FreeSync lineup is Acer's XV273K, which is a 27-inch DisplayHDR 400 compliant monitor which uses an IPS panel to deliver an ultra-wide colour gamut which supports 90% of the DCI-P3 colour space.

Unfortunately, the G-Sync monitors carry a huge price premium which is likely due to the licencing fees and hardware G-Sync requires. Acer's Predator XB273K will cost €1499 in Europe, whereas the FreeSync Nitro €1049.
