SAMSUNG S27E591C Monitor - HDMI to DisplayPort Signal Transmission Issues

Hello Dear Forum Members,

The problem I am struggling with is seemingly simple, but while browsing the forum I did not find a clear solution.

I have a SAMSUNG S27E591C monitor that has HDMI, DisplayPort and VGA sockets on the back panel. I connected the computer via HDMI and it's cool (HDMI -> HDMI), but when I connect the PS4 with the HDMI output to the monitor via DisplayPort (using an adapter as in the photo below), the monitor does not detect the signal. The case becomes so much more interesting that when I connect the other way around, i.e. from the DisplayPort computer to the monitor via HDMI, it all works.

Is it some kind of one-way transmission that the signal from DisplayPort to HDMI goes without a problem, but vice versa there is a conflict?

What cable or adapter should I use for the first option to work is from HDMI (computer or PS4 output) to DisplayPort (monitor input).



Thanks in advance for your help and suggestions,

best regards

What exactly do you want to achieve? Isn't it easier to buy a DP cable and connect it to a PC and PS4 to HDMI?

Hi,

Thanks for your interest in the topic!

Well, answering your question, the computer in which I have a DP connector is my business equipment, which as a rule stays in the office, this time I only took it for tests to check everything before I write anything on the forum.

Home equipment is a computer with HDMI output and PS4 also HDMI, the monitor has 1xHDMI and 1xDP, hence the query and not the other. If it were as you write, there would be no problem, you are absolutely right here.

And the PC connection via HDMI cable to the DP adapter and monitor also gives no signal? Also, do not forget to select the signal source on the monitor.

Unfortunately, yes, connecting the computer with the HDMI output to the monitor using an HDMI adapter -> DP also does not give any signals (the same when connecting a PS4).

The monitor automatically searches for the signal by jumping on every possible connector.

I'm afraid of the theory that the DP in the monitor is banged, in total the monitor has 4 bellows, so I rather exclude this possibility, but who knows.

Is there any proven way to test the DP in a monitor other than connecting it to another device with a DP -> DP cable?

The most reliable cable would be HDMI-DP.

You leave me no choice, tomorrow I will jump to MM and buy yes. If it works, it's cool if I don't give it back

Don't get me wrong - in my opinion such an adapter should work bidirectionally. DP is backwards compatible with HDMI DVI and even VGA, if the latter is so sure that I would not be implemented (adding an analog), the rest should work.
Such a cable suggests because it seems to be the surest solution and you have to check it somehow. The cable or adapter itself is a passive and completely transparent device. There is no way to configure either a PC or a monitor. As you wrote yourself - possibly DP input in the monitor but also unlikely. So what remains of the logical solutions? Let me know when it comes out.

Thanks for a more in-depth analysis, I'm not really up to date with all these connectors, cables and technologies myself. It's hard to keep up once you are out of circulation. I will buy a cable and test it, you can always give it back and if it works, the problem will be solved.

I will let you know how it turned out, hopefully in the right direction

When you look around on the Internet, there are two types of cables:
HDMI is DisplayPort
DisplayPort to HDMI
They are not bi-directional cables which is strange but they are. Proven in fact.

The same buddy funak is with the adapters, it probably works the other way around. I had such a case myself with Dell and only another grommet worked.

Hi everyone involved in the topic,

Well, today I took the DP cable from work -> DP, connected my business computer to the monitor and breathed a breath. DisplayPort in the monitor is functional and working properly.

I also bought a second DP -> HDMI cable in MM, the description on the back of the package (below) shows that it is a cable that works with DP -> HDMI. However, there were no others in MM, I took it for tests. Unfortunately, it turned out that the cable did not fulfill its purpose. Well, from HDMI to DP it does not work the other way around.




@irondick just so happens that I have a Dell computer and it is this one that is trying to connect to the HDMI minitor to DP. Will you tell me what worked for you?

Dell Grommet literally.

Do you have any photo or link though?

I don't, but I went to x-com and asked exactly what I wanted in the right direction. That's all.

Thanks for the information. Tomorrow I will do the same, I will go to X-com and buy it myself :)

I will let you know if it worked !!

best regards

Today I called X-Com in Wrocław and unfortunately they currently do not have either a DP -> HDMI cable or any adapter.

If you came across something specific, please let me know.

Not true. Only one of the DP variants can actually work as HDMI with a passive via. This port will be labeled ++ (Dual Mode) for the computer side.
Active vias, in particular the one from the photo in the first post (I have the same one), only work one way - the computer over DP to the display with HDMI.

Are you able to give a specific cable model (manufacturer) or a store where you will surely get something that works from HDMI (PS4 or Laptop) to DP (Monitor) ?!

Maybe it's easier for HDMI swich, for example:

Hi,

Wow, I did not know about the existence of such an option, I will read, look and decide :)

Another possibility arose. I was already afraid that I would have to switch cables endlessly or until the HDMI port in the monitor would fall :)

Thank you very much!

It is certainly not as convenient as a converter, but it is better than rearranging cables. Moreover, it seems to me at least that it is a "more reasonable" expense. And you will also hook up the satellite TV tuner to the 3rd input and you will not get up from the monitor at all

Hello, I dig up the topic after a few years, but maybe someone will need this information, so that sending the image from HDMI to DP works, we need an adapter with additional power supply from USB. I found such an option in x-com (unfortunately I can't add a link, but it is a Gembrid product). Adds a photo if the link expires in the future, so that you know more or less what to look for.
