Keywords: monitors speed mac II Message-ID: <4811@okstate.UUCP> Date: 19 Jul 89 02:21:37 GMT Organization: Oklahoma State Univ., Stillwater Lines: 45 The original post went something like this: >Does the size of a MacII monitor influence the speed of the machine? >(In other words, will a be slower than >a ?) As a related question, does >running multiple monitors degrade the MacII's performance? I only got three responses so I won't bother to summarize. The responders were: Kenneth K.F. Lui claris!wet!tempest@ames.arc.nasa.gov Don Gillies gillies@a.cs.uiuc.edu Steve Burdick sburdick@cup.portal.com Draw your own conclusions. Responses follow. ----- Start of Responses ----- Ken writes: >If the hardware itself doesn't slow down the Mac II, then the >extra pixels that it has to refresh, and take care of, and so on, >will degrade performance. If the hardware is designed correctly, >I don't think it should degrade a system's performance as a >whole, but when larger displays are concerned, and there aren't >any graphics co-processors or co-processors in general to keep >track of screen pixels, there will be system performance >dropoffs. ----- Don writes: >only the Macplus is slowed down by the display. The MacSE and higher >all have dual-ported video ram, and custom circuitry to refresh the >display (the Mac+ display is refreshed by generating CPU interrupts). ----- Steve writes: >I don't have much to offer except the observation that Versaterm4.0 >requires vastly more memory as you increase screen size and colors. >(That's memory assigned under multifinder). ----- End of Responses ----- Well, that's all.
