Why is there lines on my laptop screen

Various issues, including obsolete graphics card drivers, incorrect cable video connections to faulty ribbon cables can result in Horizontal Lines On Laptop Screen. To decide whether the software or hardware is an issue, you can enter Bios settings. But after bios, if you are still facing this issue then the problem should be with the software.

The first reason that could cause this issue on your best laptop for sketchup maybe because of the Video cable is not connected properly; this could be causing horizontal or vertical lines on your laptop screen.

You can also try reconnecting the video cable to the monitor, then check if the horizontal or vertical lines disappear. Once it has been decided that the horizontal or vertical lines on your Laptop Screen are software related, an obsolete graphics card driver is likely to be the cause.

Basically, you will start seeing the results on both screens and if you see the clear or normal display, then the problem is not the laptop screen, but it is your graphic card , a bad LCD connection, or a bad connecting cable.

Have you checked your laptop monitor out? Was there any problem or not? Or did you see the same bad results with vertical lines on the laptop screen as well as the monitor?

The thing is, your laptop screen receives signals from the motherboard with the help of a cable. But if the connection between these two is not good or solid, or the cable itself is of bad quality, having issues of breakage or anything else, your laptop will definitely start showing distorted images on the screen. To correct it, check and plug the cable in if it is not plugged in, in a good way to find out if this solves the issue. This connection from the motherboard to the LCD of your laptop can basically be found under the keyboard of your laptop.

There is no hesitation in finding it out. Also check whether the cable has any breakage or not, and if it has, you should buy a new cable.

You can also wiggle to the cable while the laptop is running to find out if it causes any screen flickering or distorting issues. Another thing you can do by yourself is to update the drivers of your laptop video card to check out if this solves the issue. Sometimes, we have old drivers on our laptops that might not be compatible with the new software running on the operating system.

To check out whether your laptop display screen really needed to be replaced, try applying gentle pressure on the upper panel of the display. If it shows colorful lines or spots, believe me, you are going to have a real problem. Therefore, you should replace it immediately. Reconnect and turn the computer back on. Look for the lines at boot up: if you see lines before Windows loads, the problem is either with the video card, the video connection cable -- whether HDMI or VGA -- or the monitor itself.

If the lines only appear in Windows, the problem is a Windows setting -- most likely the refresh rate.
