I keep getting 'check signal cable; on Samsung tv when connecting macbook using HDMI cable

I had the same problem with an older laptop. The solution was to firstly, use the white HDMI adaptor that came with laptop and connect a male to male HDMI cable to the HDMI socket on the back of my Samsung and/or my Philips monitor. However, I have two HDMI cables and it only seems to work with one but not the other.

I discovered there are different types of DVI cable and you can see everything here http://www.datapro.net/techinfo/dvi_info.html

If you have the wrong type of cable, it will not work. Mine is a DVI-D dual link and it works a treat.

Hope it helps.

same problema with me... 😟

OK, OK, I think I've solved it. Once again, I'm no techie but I hate not solving a problem, so I dug deeper,learned Korean last night and found thid solution - it's free and takes one minute.

As I thought originally, the problem stems from the Samsung expecting a TV signal in the HDMI port so you have to tell it it's a computer signal.

Go from the Mac HDMI socket to the Monitor HDMI socket with an HDMI cable.

Go to the Samsung input/source button on the remote and on that screen select tools.

Select 'edit name'

Scroll down to PC and press enter. It should now read HDMI - PC

Under apple 'system prefs - displays, select your monitor pref - mine is 1080p

and... BINGO, it should work.

If it works for you guys, I accept gifts of beer and public praise with no problem.

hi, would love to send you a couple of six pack portuguese beer.... unfourtunatly it didn't solve in my case. still get the one flash light blue blink when i connect the cable to bmp, put nothing more happends.... 😟 already ordered a vga adpator as that is the one i use with my previous macbook, tha black edition one, and it works perfect... anymore solutions?

On a Samsung TV (No matter what port the HDMI is connected to) the computer display will always appear on HDMI 1/DVI.

Hi Guys !

If you are using the Samsung TV with Apple TV then just press the "Menu" button from Samsung Remote, then go to Input, then choose the HDMI cable and select that and restart your Samsung TV. It will work prefectely.

But If you are using any other TV like LG, Sony or Philips TV with Apple TV then you need to go to the settings and then mark HDMI as default. And I'm sure It will work for you, if you will follow these steps correctely..Thanks !

That worked perfectly for me. Mid-2012 Macbook Pro, Rocketfish adapter. Except I had to select PC-DVI, as there was no PC-HDMI.
