Do you see anything on the TV when you plug in the HDMI cable or is it blank as well?
If you can see your desktop you should be able to set the output to Clone by right clicking on the desktop, click Graphic Properties, click Output To, click Clone or Extend displays, and then click the laptop display + TV option.
unfortunately no.As my the last sentence in my original reply discussed the tv is not displaying an image from my laptop. I need a means of ensuring that when I plug in the hdmi cable my laptop's screen doesn't go blank.
Some possible solutions:
- Windows* key + P. You may need to press them a few times to cycle through the options.
- Restore Intel® HD Graphics Defaults <Ctrl><Alt>F8.
that worked unfortunately my graphics card doesn't seem to support a resolution the tv can display.
Its a rather old hd tv so might be 480p. can i set a custom resolution for it?
You can try the CustomModeApp at C:\Windows\System32\
Bear in mind that setting up custom resolutions may or may not work depending on the resolutions and refresh rates supported by the display.
