Information about a new monitor in Acer’s popular Predator gaming series of screens has appeared on taobao.com. The Acer Predator X34 S is a 34″ ultrawide display with a curved 1900R IPS panel. It offers a 3440 x 1440 resolution combined with a 200Hz refresh rate (a first in this size screen) and an advertised 0.5ms G2G fastest response time. Variable refresh rates are supported through a Native G-sync hardware module as far as we can tell and we expect the 200Hz to therefore be an overclock of probably the current native 144Hz LG.Display Nano IPS panel used in some other ultrawide models. Made possible to such a level thanks to the hardware G-sync module.

Spec wise the curved 1900R 34″ ultrawide Nano IPS panel offers a 3440 x 1440 resolution, 1ms G2G response time (0.5ms G2G fastest response time), 1000:1 contrast ratio, 400 cd/m2 brightness (550 cd/m2 peak), 178/178 viewing angles, 1.07b colour depth and 98% DCI-P3 wide colour gamut. The use of the term “Nano IPS” for the panel implies it will be using an LG.Display IPS technology panel.

The screen carries the VESA Display HDR400 certification according to the spec page on taobao but does also quote a 550 cd/m2 peak brightness in the spec. Combined with the wide colour gamut of 98% DCI-P3 and 10-bit colour depth support you’d have thought this might mean Acer could apply for the better DisplayHDR 500 certification. Although that level, unlike HDR 400, requires some form of local dimming as well, so perhaps that implies that local dimming is not featured here. If so, that leaves it like many other HDR400 certified screens, offering no real dynamic range improvements or benefits for HDR content.

The spec page on taobao also mentioned a factory calibration with dE <2 the target. The connectivity part of the taobao page we believe to be wrong and actually probably from another model in their range. The table lists 2x DisplayPort 1.4, 2x HDMI 2.0, 1x USB type-C, 3x additional USB 3.0 ports and an audio output. If this is truly a Native G-sync hardware screen then that will be way beyond the connectivity options of the G-sync module in its current form, and we are not aware of any newer modules being produced yet. We would expect instead a single DisplayPort 1.4 connection, 1x HDMI 2.0 and a couple of USB ports provided along with an audio out on this model.

2x 7W speakers are integrated in to the screen and the stand provides tilt, height and swivel adjustments.

Release is apparently expected in December 2020 although no word on availability or pricing in regions like the US or UK. More information and official details when we get it, because of the muddled specs on the taobao website, some of the above may be subject to corrections.
