Second monitor not working with HDMI

Hi,

I have a AOC monitor hp Pavillion laptop and while trying to connect to the monitor using a HDMI cord, nothing is displayed. Comes up with a No Signal info. I have tried multiple cords : HDMI - HDMI, HDMI - DVI , HDMI - VGA, nothing works. The monitor is not detected. I have another laptop on Windows 7 and and if I try to connect directly with VGA - VGA, it works, but does not work with HDMI from the same laptop. Basically, it does not work with HDMI at all.

I have updated the latest graphics card, both nVidia and Intel, but no progress. 

If I use the same laptop and connect to my hd tv using the same cord it works, but does not work with my monitor. The monitor model is AOC e2450swh. It has support for HDMI. Even if I try to use a HDMI to VGA cord, still it does not display anything. 

Any suggestions would be really helpful.

Thanks

Hi,

I suggest you to download the latest drivers for chipset and motherboard from the manufacturer’s website and check if the issue persists. If there is no updated drivers available on the computer manufacturer’s website, then download the latest drivers and try installing it in Windows 8 compatibility mode. Compatibility mode runs the program using settings from a previous version of Windows.

Follow these steps to install the drivers in compatibility mode and check if that helps.

a. Download the driver from the manufacturer’s website.

b. Right-click on the driver setup file and click on ‘properties’.

c. Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 8 operating system from the drop down menu and proceed with the installation. Once this is done, restart the computer and check if the issue persists.
