    Output raw RGB color from HDMI port


    Hi,


    I am using windows 10 with Lenovo thinkpad.


    I want to output display image without any calibration exactly same data value on VRAM on my machine.

    I captured a black pixel on the displayed image which was output from a HDMI port of my machine by an external device and I saw the data value. The value was R:G:B = 0x10:0x10:0x10.

    However the actual data in my machine was R:G:B = 0x00:0x00:0x00, I confirmed by "Paint" Application.


    I thought this is a result of gamma calibration by my machine or Windows 10.


    How can I disable any calibration?

    Do I need special ICC profile which can be set by below window?

    By the way, I already had disabled "Night light settings".


    I appreciate any help. Thank you.


    Best regards,

    Tsunokawa

    HDMI port , is it input/output/both?

    Hi Ken

    On 99.99% of PC's and laptops the HDMI Port(s) are output only, there are some really high-end laptops that also have HDMI input, but they are very rare indeed . .

    Force Display Output via HDMI Port

    Windows 10 Question: The goal is to display two screens (same video screen) from the computer to two projectors for a presentation using Power Point Slides. Attaching to one projector works fine, but when I attach a HDMI splitter to hook up the second
    projector, the computer no longer detects the display and will use the HDMI port as an output.



    Thus, can you force a video output from the HDMI port using Windows 10.
