Acer Nitro XV273K Preview: 4K HDR 144Hz FreeSync 2 Gaming Monitor

Update: The Acer Nitro XV273K can run 4K, 144Hz, and HDR simultaneously without any compression. This is achieved by connecting the monitor via two DisplayPort 1.4 cables/ports.

However, this way, the FreeSync range is limited to 48-120Hz at 4K due to the limitations of the bandwidth provided by a single DisplayPort 1.4. You can still use FreeSync with a 48-144Hz range at 1440p though!

Lastly, it’s been confirmed that you cannot simultaneously use response time overdrive and AMD FreeSync, so some minor ghosting is visible at higher frame rates.


At first, gaming at 4K 144Hz was only available to those with deeper pockets who could afford a $2,000 gaming monitor with full-array local dimming (FALD) and G-SYNC HDR.

Take out the expensive FALD and NVIDIA’s G-SYNC, and you get a 4K 144Hz monitor that’s available for half the price of the Acer Predator X27 or the ASUS ROG Swift PG27UQ.

Meet the Acer Nitro XV273K, a 4K 144Hz gaming monitor with DisplayHDR 400, AMD FreeSync, and the Visual Response Boost backlight strobing technology.

Image Quality

The main thing that made the first 4K 144Hz gaming monitors so expensive is the full-array local dimming implementation which is responsible for making each zone of pixels perfectly dim or lit in order to deliver the best picture quality with life-like colors.

These 27-inch FALD monitors have 384 individual zones which in addition to the impeccable display capabilities of 1,000-nit peak brightness, 20,000:1 contrast ratio, and DCI-P3 color gamut make for a flawless HDR viewing experience.

In comparison, the Acer Nitro XV273K 4K 144Hz FreeSync gaming monitor has only a few of these dimming zones (actual number unknown at this time).

Furthermore, its HDR peak brightness is limited to 400-nits while the color gamut covers between 90% and 95% of the DCI-P3 color space. So, you won’t get as amazing picture as you’d with the $2,000 displays, but it will be noticeably better than that of a standard gaming monitor.

The Acer XV273K is most likely based on the same 4K 144Hz IPS panel by AUO with a 4ms response time speed and 178-degree viewing angles.


With the Nitro series monitors, Acer introduces the Visual Response Boost (VRB) technology which by backlight strobing reduces motion blur and trailing of fast-moving objects. This motion blur reduction method, however, cannot function at the same time as AMD FreeSync and HDR.

The Acer Nitro XV273K features the newer AMD FreeSync 2 technology which can bypass certain tone mapping processes to reduce input lag for HDR gaming as well as a variable refresh rate for compatible graphics cards.

Design & Connectivity

The design of the monitor features ultra-thin bezels at the top and at the sides while the bottom bezel is a bit thicker and brushed. The stand may not look appealing but at least it offers a versatile ergonomic support including swivel, tilt, and height adjustments.

Connectivity options include two DisplayPort 1.4 (both ports are required for 4K HDR and 144Hz, a single DisplayPort 1.4 supports 4K HDR up to 120Hz), two HDMI 2.0 (max 60Hz), a headphones jack, and a quad-USB 3.0 hub.

Price & Similar Monitors

The Acer XV273K price amounts to $899 MSRP while the release date is scheduled for Q4 2018/Q1 2019.

NVIDIA users can opt for the Acer XB273K G-SYNC counterpart with the identical specs (excluding the VRB technology) – but it will cost you an extra $400.

    I bet the overdrive worn’t work with Freesync like the XF270HU, I had the new 2018 XF270HU Abmiidprzx (Zero Frame) but Acer refunded me as there was no fix any time soon. I don’t have confidence that they will fix it since they didn’t fix it back in 2015 when apparently they had a firmware update for the XG270HU. I had to use it without freesync to be able to use overdrive. I now have a Nixeus 27 EDG with working overdrive when using freesync, loving the monitor but I really liked the design of the Acer frameless design and stand.

    I really hop these new generation AUO monitors won’t have the Freesync overdrive bug the previous ones had that Acer never patched with a new firmware. I’d love the 2560x1440p 10bit 144hz freesync version if only this had freesync 2 but in that case I wouldn’t be using HDR while gaming only while watching Netflix or other HDR content.
