hi, i have a hp laptop 1220sa that has vga and hdmi ports
it is amd based 6620g series graphics
there is no signal to external screen , via any port, the screen does get a signal as the power light is not flashing
monitor has been tested multiple cables tested and they work fine
drivers are being issue ? if i uninstall the amd driver which then returns it to the basic graphics driver the picture appears on the monitor ! however it says you must restart the pc for the basic driver to be fully installed , after rebooting the picture again does not appear on the external monitor
toggled - screens = yes
bios updated = yes
latest drivers = yes
cables tested = yes
monitor = tested yes (samsung syncmaster)
tested with win 10 = yes (same results)
is this chip failure?
thanks for any input

@kammy6000 Is this your product? HP Pavilion g6-1220sa Notebook PC, To verify: click here (there's no netbook with that model name, hence needed to confirm) that out of the way, I suggest you update to the latest graphics card drivers using the HP website: click here for updates (since you've not mentioned if you used the HP support assistant or the HP website, I suggest using the link for updates)
If you think this is a hardware (chip) failure, I suggest we perform a hardware test using the below steps: (It's outside windows, so drivers/windows are no used)
Install the latest version of the HP Hardware diagnostics (UEFI) on your device using this link: Click here for details (if not, done yet)
- Hold the power button for at least five seconds to turn off the computer.
- Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
- On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.
- Click Extensive Test.
- Click Run once, or Loop until error.
- While the test is running, the time remaining and test result for each component display on the screen.
If a component fails a test, write down the failure ID (24-digit code) for when you respond back to us.
