Can I enable HDR on an unsupported display by force?

I'm currently using the latest available Windows 10 version (x64). I have a Gigabyte GTX 750 Ti Windforce 2GB planted in my rig.

So basically what I am attempting to find on the internet, Can I enable HDR on an unsupported display?

I tried searching a lot and I couldn't find any answer to the question.

So that's why I'm asking it at this forum, is it possible? Is it a simple key to change in the registry of Windows?
Or do I have to trick Windows into thinking my display is HDR capable by changing the EDID of my display?

If I have to edit the EDID of my monitor, or some registry keys, how would I do this?

@NiallJones would you like to explain why such thing isn't possible? I actually don't really understand why we wouldn't be able to do it. – Maarten – 2019-08-22T13:13:20.113

2HDR is a hardware capability. Faking it might be possible but won’t help. – Daniel B – 2019-08-22T13:17:59.657

1@Maarten: very much simplfying it's like whether you can get coloured picture on a monochrome display with best software and graphics card – Máté Juhász – 2019-08-22T13:28:12.680

In short, it's impossible to enable HDR on a non-HDR monitor. Here's why: HDR is created by having a very high contrast ratio. For example, the contrast ratio on the iPhone Xr - which is HDR capable is around 1:1400. On your typical LCD monitor, it's around 1:600 or 1:800. The reason you can't enable HDR on your monitor is because the backlight can't produce enough light, and/or the liquid crystals in your display can't block out enough light to create good enough contrast. This is why HDR content looks so good on OLED displays, which can have contrast ratios of upwards of 1,000,000. The display on the iPhone 11 Pro for example, has a contrast ratio of 1:2,000,000.

Hope this helps :)

Yes it is possible to turn on HDR by the registry. But turning on a feature is all it will do if the hardware cannot provide the output and show the enhanced image. Seen it activated, but do not know the exact settings to adjust by regedit. Will locate and edit my answer in the near future with the details. Also saw info on this subject at Howtogeek. From what I observed, a Turned on HDR did not help any on Bill's PC due to a mid range older monitor. The card put out a good signal, and he was not using the DVI port. The monitor simply could not handle the enhanced video signal that was produced. All the items on MS's list are really needed for a true HDR experience. This page might help with some of the background on exactly what HDR is: https://www.datapro.net/techinfo/hdr_video_info.html I've used it for teaching a small group of High School Gamers. (Really wish people would post answers to the questions as posted, then explain why or why not..)
