crt monitor image distortion
i have huge 21 inch crt monitor which i found yesterday in the trash
i plugged it in now. it works but the image has some distortions
the color that should be black is bright gray and all other colors are like addition to it. the image looks very bright and with bright gray tint. setting brightness and contrast to minimum does not help much
there are some kinda scratch lines across the display. the lines form a shape of a 'lightning' with horizontal lines and diagonal that connect them. the density of lines is higher when i switch to higher resolution
the image size is severely affected by the brightness of what is displayed. it grows larger about 1 cm on each side when i open a window with white background
other than that the monitor works ok in all resolutions from the bios screen and up to 1600x1200
what can be the problem ?
