Atomos released one of the more interesting products at NAB 2016 with there range of 1500nit field recorders. These are great for not only field recording, but the new high nit screens they hold. They can be used as general HDR grading displays to get people started on the path to learning how to grade in the HDR world.
Check out the video.. They are worth a look and a great affirdable starting point for HDR.
