HDMI not working on Probook 450 G2

[Thepearl]

Just purchased several 450 G2's. None will connect to our TV via HDMI. All of the Dell's we have work with no problem on the same TV. Intel 10.18.10.3995 driver is installed.  Tried clone and extended via windows. Cannot detect the TV. Any help will be appreciated!

Press fn+f4 to alternate the computer screen image between 4 display states:

● PC screen only: View the screen image on the computer only.

● Duplicate: View the screen image simultaneously on both the computer and external

device.

● Extend: View the screen image extended across both the computer and external device.

● Second screen only: View the screen image on the external device only.

Each time you press fn+f4, the display state changes.

NOTE: For best results, especially if you choose the "Extend" option, adjust the screen resolution of

the external device, as follows. Select Start > Control Panel > Appearance and Personalization.

Under Display, select Adjust screen resolution.

To configure HDMI audio, first connect an audio or video device, such as a high-definition TV, to the

HDMI port on your computer. Then configure the default audio playback device as follows:

1. Right-click the Speakers icon in the notification area, at the far right of the taskbar, and then click

Playback devices.

2. On the Playback tab, click either Digital Output or Digital Output Device (HDMI).

3. Click Set Default, and then click OK.

To return audio to the computer speakers, follow these steps:

1. Right-click the Speakers icon in the notification area, at the far right of the taskbar, and then click

Playback devices.

2. On the Playback tab, click Speakers.

3. Click Set Default, and then click OK.

REO,

We had previously tried the steps you noted but to no avail (receive 'No signal' message on TV).  We are able to connect the HDMI to a Dell Laptop and to a Lenovo laptop and successfully view the image from each of those laptops on the TV monitor.  Thank you for your reply but still looking for an answer for using the HDMI successfully with the HP ProBook 450 G2 laptops.
