Most manufacturers offer enhanced refresh rates on televisions. Instead of 50 or 60Hz field rates as broadcasters deliver, the television increase the refresh rates to 100, 120 or even up to 600Hz. The aim is to provide smoother images although whether it makes a big difference is a matter for some debate.
Samsung LED TV's typically have a refresh rate of 120 hertz. The refresh rate is considered a important factor of quality in high end electronic televisions.
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)
A High refresh rate (Applicable to mostly CRT monitors as they actually draw your pc screen per X frames per second (refresh rate Hertz)
Refresh Rate
Hertz symbolized as Hz, describes the refresh rate of TVs.
Any displayed image with a resolution or refresh rate greater than 480i is classified as high definition.
No matter the brand, you will want something with a high refresh rate. You will want to find something with a rate of 8ms or below. If you want something really nice, a 2-4 ms refresh rate is very good.
Vsync, or vertical synchronization, is a graphics technology that synchronizes the frame rate of a video game or application with the refresh rate of a monitor to prevent screen tearing. Screen tearing occurs when the graphics card outputs frames at a rate that doesn't align with the monitor's refresh rate, leading to visual artifacts. By enabling Vsync, the system ensures that frames are only displayed when the monitor is ready to refresh, providing a smoother visual experience. However, this can sometimes introduce input lag or reduce frame rates if the graphics card cannot maintain the monitor's 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.
75 Hz
They are essentially the same except that 3D monitor is capable of a a very high refresh rate. The high refresh rate displays alternating images for the left or right eye, with the help of shutter glasses, rapid enough for the brain to recognize it as a stereoscopic image.
Both the monitor and the video card's performance are tested by the refresh rate.
