Try a vga cable for exterior monitor to see if the problem shows on it. If the exterior monitor shows ok than I guess you have a laptop screen going bad. If the problem shows on both monitors try system restore to an earlier date. Start -- type -- system restore -- should come up on the list. ------ Another way is -- Press the power button to turn on your computer and immediately start tapping the F8 key -- using the arrow keys select -- Last Known Good Configuration. Press the Enter key. I just giving you a few things to check. Maybe someone will give a better answer. I have an exterior monitor that went bad for the bottom 3/4 inch. I don't like repair shops. Just to check cost me $40.00 and no fix. ---------- VGA Connection is a blue socket on the side of your laptop unless your laptop has hdmi connection.
Thanks for your reply. I tried the exterior monitor and the problem was not present. Only on my laptop monitor. Possibly as you say, the laptop monitor could be going bad. Grrrr! Anyway thanks for your input
My notebook mostly stays connected to an exterior monitor. If you go into the control panel -- at the bottom -- You will probably have an Icon -- Windows Mobility Center -- Open it and click -- Disconnect Display. This will give you different screen choices. I only keep my Exterior monitor Display. If your computer resets and turns both screens on you will need to open Power Options in the Control Panel and make some changes. That's what I had to do to stop the computer from resetting and turning both screens back on. My eyes are not the best, so I like a big screen and the mouse. Do a Google search for laptop backlight.
