Most LCD monitors have a default refresh rate of 60 Hz. Older monitors also have limited resolution. Please check your display settings and ensure you're not using a refresh rate higher than 60, or a resolution higher than what it supports. If either one is the case, you're lucky the LCD still works.

If the lines present in the menu when displayed this indicates device mounting troubles. Possibly loose in socket. If you change aspect of displayed image do the lines move, if they do, its an electronics problem, if they are constant, and nothing is displayed in the lines. Tighten device in socket, or seek professional service.

its problem with the display cable (not the one you connect to your pc)
open the lcd display and look for a cable that is attached to the front glass display. check whether it is dameged.. it cannot be replaced
you need to replace the whole display that would be better. and cost effective

Visually, there is very little difference to the eye of the average consumer between 720p and 1080. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern.your tv is display format is 720p and blu ray is 1080p. what happen is it will be scaled into 720p. old tv set format is 480p 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another. 1080p, on the other hand, represents 1,080 horizontal lines displayed sequentially. This means all lines are displayed during the same pass. 1080p is the highest quality HD display format. 480p represents 720 pixels displayed across the screen horizontally and 480 pixels down the screen vertically. This arrangement yields 480 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.
