The TV detects that something is connected to the HDMI input? Have you checked the Win+P combination?

chacek0 · Answer

Win+P does nothing

I see it on TV

I set the power management mode in the nvidia control panel to maximum performance and updated the motherboard bios.
There is little progress because with only the display port connected, the image shows up for a moment, I attach a video.

In my opinion, it's on the PC that you need to double check that the Display Port isn't stuck.
You can see that it works during system boot, but when the system starts reading drivers and their setting, Display Port is disabled.
Have you set up Dual Monitor under Windows?

@goralpm The computer doesn't detect the second screen so I can't set up a dual monitor. And where can you check if DP is not stopped because I haven't seen it in any settings?

What kind of computer is it, its list? What graphics card? Do you have Nvidia, AMD or Intel drivers installed for the graphics or does it run on Windows drivers?

@nomudrek PC Specification: i5-9600k processor GTX 1660 super oc 6gb ASRock b365m pro 4 motherboard Ram: 12GB Viper Windows 10 Pro I have the latest nvidia drivers installed. No, it doesn't work with windows drivers either.

It remains to replace the cable with another one in the store because it seems that this one is unsuitable for use in this combination. This cable doesn't have HDCP pin connected and therefore TV or monitor can't display the image, please go to the store and ask them to check if this cable works and have them check another cable model right away to make sure it's ok.

@nomudrek Can you recommend a cable that will work? Preferably 5 meters.

nomudrek · Answer

I do not know which cable can work because I did not need to connect in this way, but reading a lot of topics with the same problem. The distance of 5 meters is already a challenge for sending the image because HDMI becomes sensitive to various interferences, the HDMI standard writes about the cable length of 15m, but the forum was full of topics about problems with shorter cables. I also have a computer with a GTX 1060 card connected via HDMI cable where the 5m cable caused problems when displaying in 4K. In this case, it remains to buy a special DisplayPort to HDMI converter adapter, which should solve the problem.
