HP 400 G6 Mini with 4k 60Hz display

[cracksalad]

I want to connect a 4k display at 60 Hz with my HP 400 G6 Mini. HDMI on the PC is version 1.4 (as far as I know) and thereby not able to do this. DisplayPort should be 1.4 (?) and be able to output 4k at 60Hz. My Monitor needs to be connected via HDMI version 2.0 (since it is the only free port). So I ordered a DisplayPort 1.4 to HDMI 2.0 cable and it works as expected with another PC with a dedicated graphics card. But it does not work with the HP 400 G6 Mini. There is another DisplayPort port as a FlexIO port and this does not work either. What am I doing wrong here?

Just to note: I tried to connect the monitor via DisplayPort (on both sides) and it works. The problem is that this is not a permanent solution for me.

Your machine has

• (2) USB 2.0 Type-A ports (rear)
• (2) USB 3.2 Gen 1 Type-A ports (rear) 5 Gbps signaling rate
• (1) USB 3.2 Gen 1 Type-A ports (front) 5 Gbps signaling rate
• (1) USB 3.2 Gen 2 Type-A port (front) 10 Gbps signaling rate
• (1) USB 3.2 Gen 2 Type-C port (front) 10 Gbps signaling rate
• (1) RJ-45 (network) connector (rear)
• (1) HDMI 1.4 input connector (rear)
• (1) DisplayPort connector (rear)

Well, the middle man (cable) is the problem. What is your DP to HDMI 2.0 cable. You have to try a different one.

Regards.

Thanks for your quick reply!

As I said, on another PC the cable works fine. The cable I got is a "Good Connections DP14-HDMI3". You can find it for example on this site: https://www.reichelt.com/de/en/displayport-1-4-to-hdmi-2-0-a-connector-3-m-black-gc-dp14-hdmi3-p2542...

The description explicitly mentions keywords like DisplayPort 1.4, HDMI 2.0, 4k at 60Hz etc.

I am wondering if the DisplayPort on my HP 400 G6 Mini is a 1.2 one and I should have got something like the Club 3D cable: https://www.club-3d.com/en/detail/2365/displayport_1.2_cable_to_hdmi_2.0_uhd_4k60hz_active_adapter_m...

@banhiencan you confirm that the DisplayPort version is 1.4?

I got the cable from Club 3D now and it works. So I guess the HP 400 G6 datasheet is wrong and the version of the DisplayPort port is 1.2 and not 1.4. This holds by the way for both the built-in port as well as the Flex Port 1 DisplayPort as far as I can tell.

Of course I can not tell for sure if the datasheet is wrong but I have testet already three different cables with two different PCs. It would be nice if HP would confirm this or explain me what I am doing wrong.

By the way I have tested the latest BIOS (version 02.10.10 Rev.A) and version 02.10.10 Rev.A as well as the latest Intel graphics driver from the HP website and the latest from the Intel website (which is actually newer).
