Laptop only detects TV via HDMI when the TV is off

0

I have an Acer Aspire 5951G laptop with an NVIDIA GeForce GT 555M graphics card and 64-bit Windows 7.

I am pretty sure that none of the components (HDMI-cable, graphics card, TV) are malfunctioning. However, my laptop only detects the LG TV whenever the TV is turned off.

I have tried rebooting the computer while connected to the TV when the TV is on but no luck.

Have you tried updating the video driver? Uninstalling the video driver and reinstalling it? Running Windows Updates? etc. – New-To-IT – 2014-12-16T14:05:53.817

Yup, I did all the things you mentioned. But my computer still only detects the TV when it is off. – Kwok Ping Lau – 2014-12-17T03:39:31.440

I got it all worked out. Apparently the issue is from the TV. Because I am using the TV from a hotel, so the HDMI is actually deactivated by the hotel.

By simply unplugging the phone line at the back, I can switch to the HDMI channel I want.

Thanks for all the help
