Night Light with D6000 dock

[havranek1024]

Hi,
I'm using i-tec 3x 4K Docking Station (CATRIPLE4KDOCKPD). I'm not using it's native HDMI output (which is DP alt-mode), but a passive DP -> HDMI converter. I believe those DP ports are driven by DL-6950 chip.

Regards,
Michał

Hello Michał,
Using a passive adapter means DP++, which means (roughly) HDMI signals over the DP plug.
I am afraid you'd need an active adapter so DisplayPort out is used.
But, before you spend money, could you confirm monitor make and model? I need to check its pixel clock...
Kind regards,
Alban

Sure, my display is Samsung LS24E390HL/EN.
Thanks for help, those technical details are way over my head

As I understand, no software workaround is possible?

Hello Michał,

From DisplayLink, this needs an active adapter for your display.

But, long before Night Mode was added to Windows, F.lux wrote software for most platforms to achieve blue light reduction.
They have added a function for DisplayLink when EnableGammaRamp is not helpful.
It works differently, as software cannot easily replace the hardware block, and therefore has some drawbacks: mouse cursor isn't "filtered" (so I recommend you switch to black mouse cursor), and printscreen will be "filtered" (but there's a key shortcut to enable/disable f.lux layer). You need to remove the EnableGammaRamp registry if you wish to use F.lux, otherwise you will get twice the effect on the DisplayPort display.
https://justgetflux.com/ is where to get F.lux from.

Kind regards,
Alban
