Framebuffers acclimated in claimed and home accretion generally had sets of authentic "modes" beneath which the framebuffer could operate. These modes would automatically reconfigure the accouterments to achievement altered resolutions, blush depths, anamnesis layouts and brace amount timings.
In the apple of Unix machines and operating systems, such conveniences were usually eschewed in favor of anon manipulating the accouterments settings. This abetment was far added adjustable in that any resolution, blush abyss and brace amount was accessible – bound alone by the anamnesis accessible to the framebuffer.
An adverse side-effect of this adjustment was that the affectation accessory could be apprenticed above its capabilities. In some cases this resulted in accouterments accident to the display.3 Added commonly, it artlessly produced broken and abstract output. Modern CRT monitors fix this botheration through the addition of "smart" aegis circuitry. When the affectation approach is changed, the adviser attempts to access a arresting lock on the fresh brace frequency. If the adviser is clumsy to access a arresting lock, or if the arresting is alfresco the ambit of its architecture limitations, the adviser will avoid the framebuffer arresting and possibly present the user with an absurdity message.
LCD monitors tend to accommodate agnate aegis circuitry, but for altered reasons. Since the LCD charge digitally sample the affectation arresting (thereby battling an electron beam), any arresting that is out of ambit cannot be physically displayed on the monitor
