The lads over at TFT central obtained a few road-maps, AU Optronics is working on four new HDR-monitors. All panels have advanced Edge Backlight Unit dimming and are based on VA-technology. 

AUO will offer various HDR display options. The edge backlight options will come in flat 32" (2560 x 1440) and curved 35" (3440 x 1440) sizes and are based on VA panel technology reports tft central:

They will offer 8 backlight areas and a colour space of DCIP3 >=90%. 400 typical and 600 cd/m2 peak brightness is provided and these panels are forecast to go in to production in Q3 2017. For full-array backlight options we already know about the exciting 27" flat panel (panel part now confirmed as M270QAN02.2), with an IPS-type AHVA panel, 3840 x 2160 resolution, 384-zone backlight, HDR support, 600 - 1000 cd/m2 brightness, 144Hz refresh rate etc as featured in the forthcoming Asus ROG Swift PG27UQ.

The panel for that screen is due to go in to production in July 2017 so the Q3 expected release date for the monitor might well be possible. We will see. AUO are also now working on a 32" HDR IPS-type AHVA panel, with similar features. A 3840 x 2160 ultra HD resolution, 384-zone backlight, HDR support, DCIP3>=95% and 400 - 800 cd/m2 brightness. This 32" version is expected to go in to production in Q4 2017 so is some way behind the 27" model.

No confirmation on refresh rate of the 32" panel, although we don't believe it will be high refresh rate sadly as it is not listed in their gaming panels, whereas the 27" version is. We have already talked about the 27" 3840 x 2160 res IPS-type panel with 144Hz above, featuring HDR support. Away from HDR for a moment AUO also have a "normal" version of this panel in plan (M270QAN02.3), with the same Ultra HD resolution and 144Hz refresh rate, but with typical panel specs elsewhere. This includes a 350 cd/m2 brightness, 1000:1 contrast ratio, sRGB gamut. That's expected to go in to production in Q3 2017. Of other note is a new 27" curved panel in plan (M270DTR01.0), which is based on TN Film technology. This will offer a 2560 x 1440 resolution but in this curved screen format (1800R), along with a 165Hz refresh rate, 400 cd/m2 brightness, 1000:1 contrast ratio. It's due to go in to production in April 2017. There's also another 27" curved panel planned, this time in VA technology and with a 1920 x 1080 resolution @ 165Hz refresh rate (M270HVR01.0). That is due to go in to production in July 2017.
