Not refreshing horizontal lines on the lower part of the screen

Have you tried switching the between the integrated onboard GPU (Intel) and the discrete Nvidia GPU controller just to make sure that it isn’t a problem with the controller?

If it happens with both GPUs, try connecting an external monitor to the laptop just to make sure that it isn’t a problem with the motherboard. Even a TV can be used as an external monitor as long as it has a HDMI input and you have a compatible HDMI cable to connect the laptop and the TV together.

If it doesn’t happen on the external monitor, then you may either have a loose display cable connection on the motherboard, a faulty display cable or a faulty LCD panel.

Here’s a link to the service manual for the laptop, taken from this webpage.

Scroll to p.74 to view the necessary pre-requisite steps and then the procedure to remove the display panel.

This will allow you to inspect the display cable connection and if it appears to be OK, then determine whether it is a faulty cable or panel.

It still happens even trying out intel and Nvidia gpu. I tried connecting it to an external display and it doesn't show. Picture is fine and no lines using the external display.

Im also thinking it might be a faulty connection.

Does this mobo support the 7590 display? Im planning to swap it up maybe fix my web cam being below the screen. Make it look good too.

Thanks for your input on this

Hi @buenabee ,

Not sure about the display.

Check what size cable connector socket is on the motherboard.

If it is 40 pin then it won't support a 7590 screen as I think that it has a 30 pin cable connection.

But this is just what I think, not what I know. ;-)
