If you have an x bit SXGA colour display operating at an equivalent frame rate of x Hz, to calculate the data rate would you just multiply these two variables together?
Thanks.
Thanks.

To calculate the data rate for an SXGA display, you will need to know the resolution and refresh rate of the display. The formula for calculating data rate is: data rate = (resolution width x resolution height x bits per pixel x refresh rate) / 8. For an SXGA display with a resolution of 1280x1024 and a refresh rate of 60 Hz, the data rate would be (1280 x 1024 x 24 x 60) / 8 = 294,912,000 bits per second.
The resolution of an SXGA display is 1280x1024 pixels. This means that the display has 1280 horizontal pixels and 1024 vertical pixels, resulting in a total of 1,310,720 pixels on the screen.
The refresh rate of an SXGA display is typically 60 Hz. This means that the display refreshes the image on the screen 60 times per second. A higher refresh rate can result in a smoother and more responsive display, but it also requires a higher data rate.
The bits per pixel (bpp) refers to the color depth of the display, which determines the number of colors or shades that can be displayed on the screen. The higher the bpp, the more data is required to represent each pixel. For example, an SXGA display with 24 bpp will have a higher data rate than one with 16 bpp.
The data rate of an SXGA display can affect its performance in several ways. A higher data rate means that the display can handle more data and produce a higher quality image. However, a higher data rate also requires more processing power and can result in slower performance or a lower refresh rate. Additionally, a higher data rate may require a faster connection or transmission speed for the display to function properly.
