Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in "hertz." (Hz)
For example, a TV with a refresh rate 60Hz, reconstructs the image you're seeing 60 times every second. Basically, the higher the refresh rate on a tv, the representation of motion will be smoother, and the image will flicker less.
Probably because the screen's refresh rate is too low. See the maker's website or user guide for instructions on increasing the monitor's refresh rate.
Refresh Rate.
Lines are visible when taking a picture of a computer screen because of the refresh rate of the screen and the shutter speed of the camera. The refresh rate of the screen and the shutter speed of the camera may not be synchronized, causing the lines to appear in the photo.
By shaky I assume you mean the monitor is flickering, you can fix this by raising the refresh rate on your monitor. Ideally the native resolution and refresh rate work best, most often this is the highest refresh rate supported by your monitor, and the largest resoltuion supported by your monitor. Try changing refresh rate to 60 Hertz first, if it continues flickering, then keep raising the refresh rate until the flickering stops. (Don't forget to click apply after changfing the refresh rate to ensure the refresh rate is changed)
i think dear it's by..refresh rate of crt..the screen refresh by vertical direction..so light pen can update it's possition..in every..refresh of crt'..but in lcd this is oppisite
Refresh Rate
It's best to have a high refresh rate. The higher it is, the better it is for your eyes. When speaking of computer games, most games today have the option of enabling "Vertical Sync" or "V-Sync". This makes the game follow the screen's refresh rate. This can be a bad thing if your computer isn't fast enough to keep up with the screen's rate.
the screen will go wacky
That is cause by the speed of the camera recording and the refresh rate of the monitor or TV screen.
A High refresh rate (Applicable to mostly CRT monitors as they actually draw your pc screen per X frames per second (refresh rate Hertz)
you might need a new screen or change the power options
The number of times in one second that an electronic beam can fill the screen with lines from top to bottom is known as the refresh rate. This value is typically measured in Hertz (Hz) and indicates how many times per second the image on the screen is refreshed. Common refresh rates for electronic displays range from 60Hz to 240Hz.
