external monitor on laptop won't show anything

Hi All,

I bought a new laptop without OS, it's a XMG advanced with i7 4700MQ CPU, an Intel HD grafics 4600 chip and an NVIDIA geforce 765M GTX.
I installed win 8.1 and updated all drivers. The laptop itself works fine. Now I wanted to connect an external Monitor ( HP w2207h) The laptop recognizes that there is an external Monitor and that it is an HP w2207h and tries to extend the desktop to it, but the monitor itself says that there is no input signal via the HDMI input and it goes to sleepmode.

When I connect my old Laptop to it, it is no Problem, the monitor shows the extendes Desktop, so the monitor an all cables are OK. (old Laptop : Win7 core 2 duo CPU geforce 9600M GT )

With the new Laptop I have the same problem, when I try to connect it to my LG TV set via HDMI, the Laptop recognizes the TV and tries to extend the desktop ( I can move the mouse out of the internal display to the TV ) but the TV says there is no input signal.

I have set the Output to 60 Hz and different resolutions and tried to duplicate the display or only use the external one. Nothing helped.

I can't force the Laptop to use the Gforce, he decides which one he wants to use.

A friend bought the same laptop and made the same installation, but when he connects to his external moniotr everything is fine, but I don't know what kind of monitor he has and I have not connected my laptop to his monitor.

Does anyone have any advice? I'm getting a little desperate.

Thanks

Hi,

Try another cable. (Yes, I have read what you said about it.)

Update motherboard bios. Check settings there too.

Have a link to the video driver package you installed?

I had the same problem as well. It took me hours to find the appropriate solution which was to flush the Secure Boot settings in the BIOS. Unfortunately, not all Motherboards have the same options.

Thanks for the quick answers.
Tried a different cable at my TV, didn't work.
And I didn't find any settings regading displays or grafics in the bios.

@ectech
what do you mean by "flush the Secure Boot settings" ? sorry, I am no nativ english speaker and I just dont understand that phrase.

Could you provide me with the exact model you have?

I will attempt to get more detailed instructions.

It is this model ( sorry, didn't find it on the english website)
mySN.de | SCHENKER XMG | Schenker Technologies - XMG A503 ADVANCED Gaming Notebook 39,6cm (15.6") - Topangebot
with all drivers according to their download site ( but I did try to update the intel drivers and the geforce drivers after the display didn't work the first time )
And I installed Win 8.1 .
Now Nvidia is at drivers version 9.18.13.2733
and Intel grafic driver is at 10.18.10.3308


but maybe it would be enought to explain the term "to flush the Secure Boot settings" in a different way, I just dont understand what you mean. update? delete? reset?

And I looked into the BIOS:
ME FE Version 9.0.20.1447
MB Series W35xSTQ_37OST
BIOS 1.03.02
KB/EC Firmware Revision 1.03.01

Maybe that helps .

Thanks

There's your problem right there. Uninstall all video drivers and software.

Download/install the latest video install package for your model.

Ok, I tried that too now and it didn't work.
So now I will pack everything and send it back to the shop.
