I'd try the other steps first, ie my previous post and if that does not work, go back to that previous image. Only flash BIOS if that does not work either...

Restoring from system image was one of the first things I tried when this happened... didn't fix. Just deleted drivers in safe mode... same situation. Guess we're running out of options here.

No.... You should still try the bios reset, not flash...

Yeah... tried reset.

Could you please post back exactly what happened when you went through these steps:

I would boot in Safe mode, delete graphics drivers, reboot with no tv or vga connection, let Windows 7 re-install...

What happened when you deleted the drivers (to what screen and resolution did it revert)?
Then you reboot, in Safe mode and install newest drivers, what happened then? (again, what was primary screen to and resolution did it revert)?

I will go through the steps again tomorrow and post in detail what happened. Should I download the latest drivers from nvdia or oem drivers from ASUS?

Ok so here goes... started in safe mode... deleted drivers for NVIDIA G105M and Mobile Intel(R) 4 Series Express Chipset Family... rebooted and display reverted to Default Monitor 800 x 600. Windows automatically installed drivers for Intel(R) 4 Series... restarted to primary display Mobile PC Display 1366 x 768 but no NVIDIA. Rebooted in safe mode... installed latest drivers from NVIDIA... restarted and things were completely messed up... Default Monitor 800 x 600.(guess the latest nvidia drivers are not compatible with this system) I repeated the above procedure this time installing the OEM NVIDIA drivers from the ASUS website... but... back to square one. Everything is working fine again except of course the HDMI output without the VGA attached.

Just a thought:
You've done a lot of work on the laptop side of the equation. I would start working on the TV's settings.

When you connect the TV to the laptop (or any W7 computer) you should get that "beep-boop" sound as Windows discovers new hardware. Most TVs that I am aware of are not plug-and-play devices but they do send a signal on the HDMI cable that computers pick up.

If the TV has more than one HDMI input you could try those. But scroll through all your TV settings to see if there is anything you can play with that controls outputs & inputs or external sources to see if you can get the PC to recognize the TV.

I also recall some issues similar to this one that actually ended up being a bad HDMI cable. Have you explored that possibility?

Yeah... I've tried all the HDMI ports on the TV... even tried another TV. Went through the menu, but didn't see anything relevant.

I don't get the "beep-boop" sound.

I only have one HDMI cable at the moment... perhaps I'll borrow one and see if that's the problem.

Hey dude,

Haven't solved your problem yet?
I was having the same problem. What I did to solve it was installing the latest nvidia hdmi driver for win 7 64 bits (my OS). After that, NVIDIA HDMI Out showed not connected, even though with the hdmi cable connected. So, with the HDMI cable connected to the PC and to the TV, I went to Control Panel -> NVIDIA Control Panel -> Display -> Change Resolution and there I noticed that the HDMI Audio output was disabled. I just enabled it and now everything works fine even with the display duplicated.

Maybe it can help ya..
