[chariegb]

I need help. Last week I dont have problem connecting my laptop on my lcd through hdmi cable. But last night, my lcd displays "no signal". Can anyone help me how to find solution and how to get the signal. By the way my lcd is an LG 30 series.

Thank you.

Have you manually switched the display from the screen on your laptop to the LCD?

Try installing the latest driver for your video card.
