FreeSync-over-HDMI: Samsung Launches 1800R Curved FHD Monitors
 

One of the big things to come out of Computex last year was our exclusive preview of a new project by AMD: being able to bring variable refresh rate technology through HDMI rather than via the more traditional method, DisplayPort. At the time, the demo seemed limited to a single monitor using a custom protocol between the standard GPU and a Realtek TCON with custom firmware to enable it. HDMI by default does not support the commands for a variable refresh rate, but the custom protocol additions made it possible with AMD wanting to move the standard in order to do so. At the time we were told that AMD wasn’t looking to produce the monitors needed to drive it, but wanted to open the standard up so any monitor manufacturer. In December, AMD announced that several manufacturers had stepped up to the plate, including Samsung, LG and Acer, with Samsung seeming to commit to more retail models than the others. Today’s announcement is a culmination of that effort.
