Automatic Mode
Automatic mode measures the time taken to display the image, and depending on the various parameters to be specified, finds a more appropriate display mode.
To define automatic mode parameters:

In the
Quality and Performance Settings window, select the
Advanced Parameters tab.
You can specify:
• Upper threshold of image display in milliseconds
• Lower threshold of image display in milliseconds
• Average on number of queries (for example, last 5 images called)
If the average transfer time exceeds the specified thresholds, MEGA chooses:
• improved quality, if the average is low (under lower threshold)
• improved performance, if the average is high (above upper threshold)
