They brought two laptops with display problems, in both cases there are no problems on external monitors (connection via VGA).
The first laptop: a three-year-old HP Pavillion G6 - bluish, artifacts, and around the letters, for example, the blue aura disappears.

Second laptop: seventeen-inch Lenovo, less than a year old, something that was described as a "gradient" appeared, at times (when the chip is loaded?) there is a distortion in stripes. Matrices have already been changed on it - it didn’t help, the photo is only from the owner:

Where to dig in both cases - cables / video chips? So I understand that since the image does not depend on the opening angle, the plume has nothing to do with it.

The place where the cable is attached to the matrix, I had one like this: no matter how you twist it - nothing, but you press on the corner - the picture changes.

Chip break.
Less likely - a crack in the motherboard.

If problems are not observed when an external monitor is connected, then the chip and the mother are out of business.
Maybe the train has departed or a factory marriage.
Run normally when connecting external monitors - so that the core temperature rises. If everything is OK - dig towards the cable / matrix.
+ Maybe something with food? I had a similar thing with gradients in Uni - it turned out that the power cable just went out and, apparently, it was short somewhere.
