There may be a problem with the image card itself it may need replaced. Also under the monitor or on the monitor there should be a button or knob that can be turned to adjust picture quality and color.
How an image is formed on the tv screen
An image obtained on the screen is called a display or a screen image. It refers to the visual output that is produced on a screen or monitor through the stimulation of pixels.
A virtual image can be seen on a screen when the light rays from the object converge to form the image on the screen, even though the image is not actually located at that point.
If you can get the image on your computer screen, try using Screen dash. You can then capture the image of your screen then edit the photo, save the image, or image host it.
It is called a real image. Only a real image can be projected onto a screen.

If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
An example of an image that cannot be obtained on a screen is a holographic image, which requires special technology to project a 3D image in space.

Yes, a virtual image can be projected onto a screen by using a converging lens or a concave mirror. This type of image appears to be located behind the mirror or lens, as the light rays do not actually converge at the position of the image. By placing a screen at the location of the virtual image, the image can be displayed.
