Acer Essential Monitor 21.5" EK221QE3BI FHD VA Panel/ VGA+HDMI/100Hz

The refresh rate is 100 Hz

Thanks to the high refresh rate of 100 Hz and the Visual Response Boost technology, which provides a response time of 1 ms, during the game the frames will smoothly change each other with almost no blur effect.

VRB technology makes it possible to reduce the MPRT (Moving Picture Response Time) response time to 1 ms. This is achieved by quickly turning off the backlight or empty black inserts between frames (they are also called "blinking"). This effect is less noticeable when changing colors quickly.

Radeon FreeSync makes it possible to forget about obstacles, delays, distortions and "breaks" of the image that prevent you from fully immersing yourself in the game world. Modern technologies guarantee perfect playback even at high frame rates.

Ultra-Low Blue Light technology

BlueLightShield technology reduces exposure to potentially harmful blue light by adjusting color hue and brightness. You can easily find and select four different filter options on the screen via the OSD menu to find the best fit for the job.

Flicker-Less technology

Flicker-Less technology eliminates screen flickering, ensuring stable power supply to the display. This minimizes the incidence of eye strain and other potentially dangerous eye ailments when you are involved in long, drawn-out gaming sessions.
