HP 14-cb172wm HDMI

[jto85]

I have  14-cb172wm and a 14-dq1043ct laptops,  both out of warranty.  The 14-dq1043ct works with 4 monitors/TV's that I have tried;  Samsung 525D, Sharp LC-46D92U, Sceptre E22 and an older LG TV mounted on a class room wall.  While the 14-dq recognizes and works with all, the 14-cb172wm will recognize only the Sharp and Septre, not the Samsung or LG. 

Both computers run the latest Windows 10 Home edition with all updates.  I have swapped HDMI cables and also used the same cable with both laptops with no apparent difference.  Any suggestions would be appreciated.

Thank you for the reply. Unfortunately, the Samsung monitor is still dot recognized, I don't currently have access to the LG TV.  The Samsung has never been recognized by this laptop, and I only tried the LG this past month.

The Product Number is 9VK98UA#ABA.

Hello Praveenbv,

My issue is not to improve the performance of a monitor, but to be able to detect the connection to the Samsung and LG external monitors over the HDMI port.  I have not tried a system restore.

@jto85,

Uninstall the graphics driver from the device manager and install the latest drivers and BIOS from the links below.

Link to update the BIOS.

Also, update the graphics driver using this link.

You can try updating the drivers on your PC using an HP support assistant.

Hello Praveenbv

I tried the links you provided but got a warning of possible tampered files.

I again ran HP support Assist and drivers and BIOS are reported up to date,

I checked BIOS and display driver versions and have:

 BIOS version F.19, by Insyde

 UHD Graphics 600, version 27.20.100.9664, date 6/1/21 ( this is the same version

used on my HP 14-dq1043cl that works with all HDMI connected monitors.

Praveenbv,

Just checked Windows 10 update and downloaded Intel Display driver 30.0.1.1191, dated 12/3/21. It didn't show up on HP Assist.

It didn't fix the problem of detecting the Samsung monitor.
