SER6 Pro - New - Displayport Not Working?

MarioViva

Hi, I have a SER6 MAX 7735HS and I also experimenting an unusual issue with DP 1.4 cable (but my monitor supports only 1.2 version).
In the last week with DP connection I have some randomly orizzontal flickering on the top part of the Monitor.
In fact I'm using an HDMI connection (with that I don't have problems).
Can someone explain me what I should do to resolve this problem?

I have received my active DP1.4-HDMI2.0 cable and it worked. I don't know if there is a active DP-cable for monitors...

Just wanted to post this.  I just ran into the same problem.  The problem is the display-port technology has changed.
the old adapters are not backwards compatible.  The fix is getting CalDigit DisplayPort 2.0 to HDMI 2.1.
that's the one i got and it works :)

+1 to DisplayPort 1.4 being necessary.  I have several working 1.2 -> HDMI/DVI cables that won't work with this device, however an inexpensive Active DP 1.4 -> HDMI enabled the port with a very old 4:3 DVI-D at 1600x1200.  Pretty much the most bizarre use case possible (unless you're building a dual monitor MAME rig and you don't want to tie up any front ports).  The specific adapter I used was "IVANKY Active DisplayPort to HDMI Adapter, 4K@60Hz Unidirectional DP to HDMI Adapter" (B086QQT48Y on Amazon).

There is so much incorrect information on this thread regarding this issue.

The problem here is that the Displayport on these mini pcs (as well as other brands like Minisforum) may not support Dual mode/DP++ on them due to cost/corner cutting by the mfgr.
Dual mode is required to use a PASSIVE cable/adapter to get an HDMI signal. Without Dual mode support, you need to use an ACTIVE cable/adapter for it to work.
It's as simple as that.
USB-C ports work because the USB-C -> HDMI cables/adapters are all ACTIVE ones.
Not stating whether an adapter/cable is passive or active (by either a person or a vendor of said cable) is irresponsible, as it's a crucial detail to functionality and feature set. You should not buy any cable which doesn't state which kind it is or listen to anybody that doesn't specify it.
This has nothing to do with old DP versions or old technologies, it's simply the pc mfgr not supporting a certification.
