Samsung has just released two monitors with 4K (UHD) resolution and support for AMD FreeSync technology. They are called Samsung U24E590D and Samsung U28E590D and they are the first 4K monitors to support AMD FreeSync synchronization technology, also called adaptive sync.
The U24E590D has a PLS panel with a brightness of 300 cd/m2 and a 4ms response time (GtG). The U28E590, however, has a response time of 1ms and a 370 cd/m2 brightness spec. PLS panels are Samsung’s version of the popular IPS panels and they offer similar traits to them too, such as the superior viewing angles and excellent color quality. Both monitors have two HDMI inputs: one 2.0 port (MHL) and one 1.4 port, along with a DisplayPort 1.2 connector each.
Both monitors are flicker-free (PWM-free), compatible with both Mac, Windows and all other system that can be connected via HDMI or DisplayPort and 100% support for sRGB color space. The displays are also VESA-compatible, meaning that they can be mounted on a wall.
The monitors are very budget minded, so you will get great value for the money. The 24-inch model will be sold for around $399 when it is released on the 26th of July and and the 28-inch model is available already now and costs around $599. These monitors are very promising 4K monitors for 2015.
