Dual Monitor Issue

[Tynendir]

Hello,

I had a setup when I'm at home that has worked for over a year. My laptop screen as main display and an old TV as a second monitor. The TV is plugged in via a HDMI cable (only one entrance possible on my laptop).

Recently I tried to download and install one of your drivers via GeForce Experience but the installation failed. I later noticed that my GTX 770M did not appear anymore in the Device Manager. I then proceeded to do a clean install of the GPU drivers, successfuly installing the latest version avalaible for my GTX 770M (361.75).
Now however my second monitor does not work, onyl displaying "No Signal" error. I thought at first that it was the cable (as it was a bit battered) but nothing changed when I replaced it.

When I go the Nvidia Control Panel and on the Set Up Multiple Displays page I can see both my laptop and my TV screen in the Displays tab. However they are under my inbuilt Intel(R) HD Graphics 4600 and I can't how to force use my GPU.

When I go the Surround Physx tab I can see that both my displays are connected to my Intel but there are no options to switch one or both of them to my GPU.


Here are a summary of the fixes I've tried so far:
- Clean install of the GPU drivers.
- Replacing the cable.
- Switching HDMI port on the TV (as I only have one HDMI port on my laptop). And I did make sure that my TV was focused on the right HDMI port.
- Going into the BIOS to find the video setting and forcing my GTX770M to be the dominant card. No such option exist in my BIOS.
- Rebooting many times.


Please note that it used to work.

In the hope that you can help me,

Tynendir

Hi,

Since both display shows in NVIDIA Control panel that means it's being detected with no problem. Press the Windows key + P at the same time and select between Duplicate or Extended display then press Enter and see if you'll get the display back on both screen.

This how to set NVIDIA as the default graphics card.

Thank you for your answer but this did not solve things.
Actually I realized that my TV was not detected properly as it was displayed as "TV" instead of "Samsung". I got it to work through a VGA cable but it's not an optimal solution as the image is pretty ugly compared to what I had with a HDMI cable.
I tried reinstalling both my Intel Graphics and Nvidia drivers and it showed Samsung in the Nvidia Setting. But as soon as I tried to set it up as my secondary display and press apply, the "Samsung" display would untick itself after a view second without showing anything but the "No signal" message on my TV. In the end I had to restore before I reinstalled both of the drivers as it created loads of issues (and thus despite installing the correct drivers from MSI).
I did try to paramater my displays properly (I know about Windows + P).

Thanks,

Tynendir.
