Windows 10: Connecting external monitor to laptop via hdmi with almost dead intel gpu

My laptop internal gpu intel 630 is almost dead only works on Microsoft basic display driver, if i install the intel drivers artifacts starts appearing so i was thinking to buy external monitor for around $200 & connect it via hdmi to dedicated gpu but i’m not sure if that will work without installing intel drivers?

'No signal' on external monitor when connected to laptop via HDMI

Hi,

I've just updated my laptop from Windows 7 to Windows 10. When I plug my laptop into my LG 4K TV or an external monitor using an HDMI cable there's a "No signal" message on the monitor/TV. Prior to updating to Windows 10 I used to be able to plug it in via HDMI to the TV and it would automatically display correctly.

Here's my laptop details:

Windows version: Windows 10 Home 64 bit, version 1909
Model of laptop: HP Pavilion dv6 Notebook PC
Processor: Intel Core i3 CPU, 2.53 Ghz
Memory: 8GB ram
Graphics drivers: Intel HD Graphics and AMD Mobility Radeon HD 5000 series


I've tried the following suggestions to no avail. I've tried:

-two different HDMI cables.
-changing the order in which the cables are plugged into the laptop/TV, as well as after a restart.
-connecting to an external monitor as well as the TV.
-updating both the display adapters (both are up to date).
-rolling back the display adapters.
-using the windows key + p command to toggle between 'duplicate' and 'extend' screen arrangements
-using the 'detect' button for multiple displays in the display settings (pressing this does nothing)

I've noticed when it is connected, under both the display settings and the intel graphics control panel, there is only a single display listed (that of the the laptop). There is no second display listed under the 'multiple displays' panel. Also, when I plus the cable into the laptop from the TV, the TV will bring up an 'HDMI 3' selection box (when clicking on it, however, 'no signal' results).

Does anyone have any other ideas how to get the laptop to display on my TV via HDMI?

Thanks very much for the help

Someone helped me resolve this. For me, the following worked. Uninstall the AMD catalyst software. Download the crimson beta version from here: https://www.amd.com/en/support/graph...radeon-hd-5830. Restart after installation. Then press window key + p and chang it to 'duplicate' and it should display correctly.

 

Manage external monitor with GeForce GPU instead of Intel GPU

I bought a new external touch monitor for my laptop.

It works fine (display and touch). However, the image is a bit pixelated. I noticed that Windows is managing both laptop monitor and external monitor with the built-in Intel GPU instead of the GeForce one. I am OK with this configuration for the laptop GPU, as i barely use any graphically heavy operation, and it's better for battery life. However, for the external monitor, i need to compensate the pixelated image, so i want to manage it via GeForce GPU. Also, the laptop is always plugged in to an AC adapter power source while using the external monitor.
