Graphic card causes display errors/diagonal lines

[TNguy125]

Hello!

I don't know how to describe this problem, but I have issues with my display. I was able to temporarily solve it by disabling the Intel HD Graphics 5500 card on my Acer laptop, but I can't adjust the brightness of my screen anymore and connecting my laptop to my TV via an HDMI cable doesn't work anymore.

I tried updating it, but it is the most recent one.

Please tell me if you need more information! I'm more than happy to provide them for you.

Thank you!

hi, there was an error message when i tried to install the driver

[Amy_C_Intel1]

That driver is the version provided by your computer manufacturer. You should be able to install the version without any errors, but since this is not the case I recommend you to contact Acer support for them to help you installing this driver. https://www.acer.com/ac/en/US/content/support Amy C Intel Customer Support Technician Under Contract to Intel Corporation
