Samsung NP300E5C Laptop & LE 328541 TV HDMI: No Signal Issue, Settings & Efficient Cable

I have already looked through all the possible posts in this topic, I have already done a lot of changes in settings etc. etc., but unfortunately I did not find a solution.
After connecting with an efficient cable (checked with a friend - works) my HDMI laptop I can choose the TV's HDMI source for TV (it connects), but I do not have a picture, only the "no signal" message. Once a connection was established immediately, a few months ago it suddenly fell and I have no idea what I can do to restore it.

Samsung NP300E5C laptop, Windows 10, Intel (R) graphics card, HD Graphics 3000
TV Samsung LE 328541

Please help.

Usually laptops need to be switched to work with a different monitor than the built-in LCD.
That is probably also in your case.

If there is no picture from this other source of HDMI on the TV, it means that it is damaged.

The problem is that the fn + f4 combination does not work at all
Works Windows + P, I choose mirroring, cloning, all options tested and nothing

Chromecast works connected via HDMi, so this option is off

Strange, because the attached picture comes from the English manual of your laptop
However, in fact, in the Polish instruction with WIN8 and above it is actually like you say - I'm sorry.



Check the connection from another source to the TV.
Check that the cable is good and that it "touches well" - move the plug and press it down.

Chromecast works.
The cable is ok, my pal works, I pressed many times

It is established that the HDMI connector on the TV is working, so the cable also stays connected to another TV and check how it behaves.

And here is the problem, because it also does not work

Do it this way:
- switch key combination on LCD + HDMI
- go to the screen settings in Windows
- check if your laptop detects there is a second HDMI monitor

Detects, because in the graphic options I get "send to" and "digital TV" but nothing else happens.
I only have an audio signal when I connect the cable and nothing
The sound disappears in the computer and "no signal" appears on the TV screen - there is no picture or sound

Well, it's probably a visit to Samsung service

Shit ... I was afraid of that

For everyone who is tired like a friend. The problem was similar. The television showed no signal, and Windows (10) showed the connected additional display. It helped me (Lenovo g510 + Philips 32 ...) to refresh in the settings of the graphics card (Intel) from 59 to 60.

I had such a problem and helped translate the HDMI cable to the appropriate socket, i.e. MHL / DVI

Because I also have a similar problem with a smart TV every day, as a result of repeated attempts I came across like this. I turn on the TV set a moment before the computer and the devices are fully synchronized. Any disconnection of the HDMI / DVI signal will result in a lack of communication. I picked it up as a property of a TV set that does not have a DSUB connector. I haven't tested yet whether it behaves identically on other connectors.
