Windows 7: Acer Iconia W500 HDMI not working on one TV

Acer Iconia W500 HDMI not working on one TV

Hi all,
Hoping some one can help me with this. I have Acer Iconia W500. It is wokring great in all situation except one. It has one HDMI output. I can connect it to my 24" LCD tv with HDMI cable and works perfect (I can switch between single desktop, clone, extend etc). When I connect to my LG 42" LCD tv using HDMI, the screen goes blank and tv says no signal. When I connect to the TV and start the tablet, I can see starting Windows on both screens. Seems once Windows is loaded, I get no signal on the TV from the tablet. It did work the first time and I was messing with the display setting and I think I accidently turned off backlight on the tablet.

I use logmein.com to remote into my other machines. I tried using logmein to connect to this, it works when the tablet is not connected to this TV, but once it it connected to the tv, I only see a blank screen. I also tried UltraVCN, I get same thing, blank screen.

I need to know if there is any way I can either delete the LG tv profile or something where when I connect the HDMI cable, it will revert back to default setting and the video will show on both tablet and tv like it does when I connect the other TV.

Sorry about long thread, but wanted to make sure I enter all the details of my problem. Below are the system details.
  • 10.1” HD Multi-Touch LED-backlit TFT LCD Display: (1280 x 800) resolution, wide viewing angle

I think your laptop is outputing a resolution that your Tv does not support, try lowing the resolution, or identifying your tv on windows as a second monitor and then choose the correct resolution.

some modern tv sold as 1080p, arent actually 1080p, they can just receive a 1080p signal and they then drop it down to the desired resolution for the input. This works fine for tv's and inputs such as sky or bluray drives as you wont notice the difference. but it can confuse computer signals.
