Re: Official Black-screen thread - We need your help!

I've been following this thread for a while, hoping a fix would be released already... I have a brand new laptop, HDMI port to my external monitor doesn't work. When I reinstall the Intel driver, it works, until I restart or remove the cable and reinsert. Though maybe it was a hardware issue after all, sent the computer in to the manufacturer, they replaced the whole motherboard, did not help.

Are you willing to send your system to us? (Yes/No) No, don't live in the US

What is the make/model of your system? (COMPLETE model name required)

Gigabyte U24F

What is the model of your CPU?

Intel Core i7-4500U

What is the make/model of your failing display(s)?

-Intel HD graphics 4400

-Nvidia Geforce GT 750M

If laptop, is your built-in display failing? (Yes/No)

No

What is your operating system?

Currently Windows 8.1 (although I have tried Windows 8 and Windows 7 as well)

Is it a 64-bit or 32-bit operating system?

64bit

What display driver version do you have installed?

Intel - 10.18.10.3621

Nvidia - 9.18.13.3523

What type of connection are you using? (HDMI, VGA, DP, DVI?)

HDMI

What happens that results in the blackscreen failure?

After installing/reinstalling Intel driver, HDMI outputs perfectly to my monitor (AOC F22). If I sleep, restart, or remove the cable and reinsert, the computer no longer recognizes that there is anything attached to the HDMI port (does not appear on any of the menus - Screen resolution, Nvidia control panel, Intel graphics control panel, etc.) and does not output any picture. VGA output works fine always.

This monitor and cable work perfectly fine with any other computers.

I have tried all the new drivers, as well as older ones, tried going back to Windows 8 and Windows 7 (Windows 7 also had other compatibility issues on this computer).

Sent the computer in to the manufacturer, they replaced the motherboard and I received it today, still no change.

NOTE: it is possible that the HDMI works with other monitors/cables, I have not yet spoken to the manufacturer why they sent the computer back when it still doesn't work, maybe it worked on their monitor?
