I think, this is only slightly off-topic, since it is about a 68040 machine and monitors are generally important for Quadras, too.
I want to use a specific monitor on my NeXT Colour Station (68040). A friend of mine wants to give me a Ikegami 20 inch Trinitron monitor for free, but the heavy piece has to be shipped over a few hundred kilometers, so I want to clear this first. The NeXT monitor specs are: Horizontal Scan Rate: 61 KHz Vertical Scan Rate: 68 Hz Sync-on-green So, the monitor, if not an original NeXT monitor, has to be a multiscan monitor to match the requirements of the NeXT. The monitor I am interested in is the Ikegami CT20HB Rev. G I have the needed 13W3 to BNC adapter. Well, you maybe know these self declared "monitor authorities" like www.monitorworld.com or www.si87.com. I looked on their pages for the technical specifications of the Ikegami display, but I found most confusing information: http://www.monitorworld.com/Monitors/ikegami/ct20hbrevg.html the description of the ikegami display reads there: H Freq/ V Freq: 59.52; 47-65 Khz / 73.68; 54-80 Hz The site says it is fixed frequency!!! But then again they write that the monitor scans horizontally from 47-65 Khz and vertically from 54-80Hz... I found more irritating data about "fixed frequency" monitors on those sites: For example, look at this: http://www.si87.com/MonitorSolutions/sun/gdm20d10.html It is about the Sun 20D10 which specs read: H Freq/ V Freq: 60-82 Khz / 50-150hz But this site states that it is a fixed frequency monitor. False? Same here: http://www.si87.com/MonitorSolutions/sgi/gdm20d11.html#MACcable Can this serve as an explanation: Maybe they also consider a monitor to be of the fixed frequency type if it scans only through the upper area of frequencies. You know, on a PC, the monitor has to be able to handle also very low horizontal frequencies like around 34khz - in the Bios screen or in Dos. So - maybe - a monitor is considered to be of the "fixed frequency" type generally, if it is not PC compatible, even if it is a multi-scan monitor in the small range of higher frequencies. To end with a clear formulated question: Is the Ikegami, which has H Freq/ V Freq: 59.52; 47-65 Khz / 73.68; 54-80 Hz a fixed frequency monitor or a "small range multiscan" display that would work on the NeXT? -Peter -- Quadlist is sponsored by <http://lowendmac.com/> and...
