“Is this monitor capable to do 4K @60 fps + HDR 10 over Diaplay port 1.2 this monitor supports ? I saw a user review mentioning he was able to get this but, I am surprised given that over DP it is only 1.2 and we need DP 1.3 for HDR over DP in this moni”

Actually it could also be a hardware implementation of HDR over DP port. I read somewhere in one of the sites. Well it is true that HDR extensions were specified in version 1.4 of the DisplayPort standard, but as far as what devices support, it depends on what you mean by "DP 1.2" since version numbers apply to the DisplayPort Standard (a PDF document) not to actual hardware. There is no technical meaning to "this device supports DisplayPort 1.2", it's just a casual shorthand people use. Usually what people (and manufacturers) mean when they say "DP 1.2 port" is just that it supports up to HBR2 speed. It may or may not also support the HDR extensions as defined in version 1.4 of the DP standard, depending on how new the controller is. But even if it does, some manufacturers will still label this as a "DP 1.2" port, because it is normally used to just indicate the maximum speed of the port. So there are monitors with "DP 1.2" ports that support HDR (i.e. LG 32UD99). Basically from a technical perspective, the question "do DP 1.2 monitors support HDR" has no answer since there is no technical definition of what a "DP 1.2 monitor" is. The only real question one can ask is "do monitors that are labeled as 'DP 1.2' by the manufacturer support HDR?" the answer is "yes, it's possible".
Sorry, there was a problem. Please try again later.This monitor's displayPort version is actually DisplayPort 1.2 with version 1.4 extensions (Like HDR and HDCP 2.2). It's not software based HDR.As said in the Wikipedia page. HDR extensions were defined in version 1.4 of the DisplayPort standard. Some displays support these HDR extensions, but may only implement HBR2 transmission mode if the extra bandwidth of HBR3 is unnecessary (for example, on 4K 60 Hz HDR displays). Since there is no definition of what constitutes a "DisplayPort 1.4" device, some manufacturers may choose to label these as "DP 1.2" devices despite their support for DP 1.4 HDR extensions.[51] As a result, DisplayPort "version numbers" should not be used as an indicator of HDR support. https://en.wikipedia.org/wiki/DisplayPort
Sorry, there was a problem. Please try again later.Yes, it does support HDR over the DP input. This is because it is a software-based implementation of HDR and thus is not based on the implementation in the later DisplayPort specs. That said, at this price point, high quality or even acceptable quality HDR should not be an expectation (no matter the brand), and in my experience it's barely noticeable. I keep it turned off.
