So..here is the thing..I reallyreallyreally hope you can try to help me on this one

My laptop is Sager with gtx 670m and Intel HD 4000 gpu, today i just bought a new tv which is LG29MT45D....when i tried to connect it to connect my notebook to the lcd it says no signal on the screen...

No big deal i think..maybe the problem with the HDMI cable...but nope...I borrowed one of my roommate laptop which is asus with intel hd3000 gpu and it works fine with my lcd...He just plug it and it was instantly displayed on my lcd...so no problem on the lcd hdmi port and the hdmi cable

So i tried to test it again on my laptop..after 3 hours i just gave up..here is the little bit of thing that i collected from the past 3 hour...

NB: my software is windows 7 64 bit ultimate version

1. My laptop can recognize the television just fine...it is even connected to my laptop according to my display setting
2. My native resolution between the notebook and the tv is already the same..i checked it thrice
3. i already upgraded my intel HD4000 driver to the latest patch..so i think no problem there
4. My laptop can configure the display just fine...it's just the television didnt receive any signal hence the no signal ..i think..
5. I have done number 1-4 in several ways i even rebooted several times to no avail

Is there anybody out there that can help me? even a little hint of what truly happened to my laptop will put smile on my face XD
