I have a Sony Vaio VGN-2950 with a HDMI connection and a Samsung 24A350H external monitor with an HDMI input.

If I connect the laptop to the Samsung via a VGA connection, it works fine. However, it won’t work when using HDMI; the screen stays blank.

Any ideas how I can get it to work with HDMI?

  • Are you sure the cable's good? – evamvid Apr 6 '14 at 0:27
  • Resolution needs to be "good" maybe? – rogerdpack Dec 6 '17 at 17:48

As long as you have your display drivers installed properly, you should see the option "Output To ->" when you right click on your desktop and look under display or properties. If HDMI is connected, You should see the option Output To - TV.

I had the same problem. I also have a Sony Vaio laptop and a TV connected using HDMI, it used to work fine, but one day it did not. The VGA cable still worked fine.

Here is my solution:

  • Reboot PC.
  • Go to BIOS, by pressing F2 or whichever key is correct for your computer.
  • Within the BIOS settings, disable Intel Visualization Technology.
  • Reboot computer.

And it should work. If there is no such option, go to BIOS and restore the original BIOS settings from the BIOS menu.

  • I think you mean Intel Virtualization Technology... which has nothing to do with display output. There is no such thing as Intel Visualization Technology. – Cliff Armstrong Jun 19 '18 at 2:38

You might need to check whether your graphic card driver services are working or not, having them disabled might not detect connection to external device.

  • Just for those who down voted, I had similar issue with HDMI not working from my laptop to my TV, for some reason NVIDIA GPU driver service was not started, when I started it, the TV showed the output! – MusuNaji Jan 3 '18 at 17:04
