The XV28 is Acer’s first monitor with HDMI 2.1 support, based around a 28-inch UHD panel with a maximum refresh rate of 144Hz and AMD FreeSync. Compared to HDMI 2.0’s 18Gbps bandwidth capacity you’ll find on most monitors, 2.1 offers a much-improved 48Gbps. This massive increase in bandwidth is what allows the monitor to display games in 4K with a 120Hz refresh rate – you won’t be able to hit the monitor’s full 144Hz capability in UHD, however, but this is just a limitation of the HDMI technology.
This monitor will also be perfect for the PS5 and Xbox Series X which are capable of running some titles at 120fps in UHD resolution. Even with the best graphics cards in your PC, however, you’ll find it impossible to run some titles like Cyberpunk 2077 at 4K with such a high frame rate.
