Preparing images for screen
When preparing images for screen, it is important to test images on all the major browsers and make sure images don’t take up too much bandwidth.
It is important to note that DiDA eportfolios should be designed to be viewed at a screen resolution of 1280 x 1024 pixels (resolution of a standard computer screen).
However, the screen resolution of a specific project may alter depending on the output format specified in the SPB eg when designing for an iPod Touch, your graphic should be 480 x 320 pixels. It is important to maximise the screen resolution of the graphic you are creating in relation to the output specified.
The refresh rate for CRT refers to the number of times the screen is redrawn each second. This number is measured in hertz (Hz). A typical rate for a CRT monitor is 60, 75 or 80 Hz, but some monitors support a much higher rate. A higher refresh rate reduces screen flicker and eyestrain. You can alter the refresh rate for CRT by changing the settings in the monitor's control panel. This should be set to the maximum refresh rate possible.
