    Displayport/HDMI Adapter

    HI everyone!

    I have a Thinkpad T420 and recently i bought a Displayport-HDMI Adapter for it so i can i connect it to my TV.

    But it turns out that although the video is connected and clear the audio still plays on laptop instead of TV. And also that the TV shows ''DVI'' connected instead of HDMI which i assume is the problem.

    Please do suggest any solution as quickly as possible.

    Thanks in advance.

  3. The system detects the DisplayPort -> HDMI adapter as HDMI

    The essence of the problem: due to the fact that the HDMI port on my RTX 3060 failed, I had to connect a “DisplayPort -> HDMI” adapter and an HDMI cable from it to the TV. The video is transmitted wonderfully, but the sound is not. I connected it from another device with the same cable to the TV, the sound worked, that is, there are definitely no problems with the cable and the TV. After doing a little research, I found out that for me (as well as for some other users) DisplayPort is defined as HDMI (yes, the cable is really HDMI, but the converter (adapter) is “DisplayPort -> HDMI”), which is why apparently the converter (adapter) doesn't convert DisplayPort audio to HDMI because it already accepts HDMI audio (i.e. there's some kind of conflict).

    So what am I getting at. Is there a way to get the system to recognize my DisplayPort as DisplayPort and not HDMI?

    I want to say right away that I updated all the drivers, rebooted the computer, rebooted the TV, rebooted the cable I bought a displayPort to hdmi adapter which was working perfecty with both audio and video... :)

    Since masterpiece-Microsoft “knows how” to make not only software, but also a website I bought a displayPort to hdmi adapter which was working perfecty with both audio and video... :), you will have to insert a link to a third-party resource with supporting images - imgur.com

    StarTech Announces New DisplayPort to HDMI and Mini DisplayPort to HDMI Adapters

    StarTech.com, a leading manufacturer of hard-to-find connectivity parts, has announced the availability of three new Active 4K-capable Video Adapters, which enable users to stream audio and video from their DisplayPort 1.2 or Mini DisplayPort 1.2-equipped computer to an HDMI-equipped TV, monitor or projector. The new adapters offer active signal conversion, which unlike passive video adapters does not require a multi-mode DisplayPort (DP++) source signal, greatly expanding compatibility options.
