AJA's Hi5-4K Mini-Converter provides a simple monitoring connection from professional 4K devices using 4 SDI outputs to new displays with 4K-capable 1.4a HDMI inputs. Hi5-4K is a single, highly-portable device that allows more affordable monitoring solutions in professional workflows.
The latest generation of 4K monitors utilize the new HDMI 1.4a connection, which allows a full 4K signal to be passed over a single cable. Typical professional 4K workflows use four SDI cables to carry the full resolution image, making it difficult to incorporate the newer monitors. Hi5-4K is an easy-to-use converter that bridges the gap between these two worlds.
Up to 8-channels of embedded audio in the incoming SDI signal are carried through seamlessly into the HDMI 1.4a output, ensuring your audio is always in sync and can be easily played back on the connected monitor.
4K and UltraHD
Typical 4K signals use a resolution of 4096x2160 pixels while UltraHD signals measure 3840x2160. This difference can prevent some monitors from being used either in full 4K workflows or in UltraHD workflows. Hi5-4K can compensate for these resolution differences, allowing UltraHD monitors to be used in 4K productions and vice versa.
Hi5-4K also supports High Frame Rate (HFR) inputs. 4K/UHD signals at 50 or 60 fps can be fed into Hi5-4K and will be output via the 4K HDMI at 25 or 30 fps, allowing viewing of 4K HFR images on standard consumer 4K monitors.
Not every job is a 4K job. When you're not working in 4K, Hi5-4K can still be a useful tool for converting HD-SDI to HDMI. A single HD-SDI signal coming into the Hi5-4K will be sent out as an HD resolution HDMI signal, much like AJA's Hi5-3G Mini-Converter.
