It may be that the monitor in question can only display at that resolution. The name �Apple Display Monitor� is not one that I recognise � can you check to find out the exact name of the monitor, and if possible also the family number? This begins with an M followed by four numbers, eg M1212 is the number for the Macintosh Color Monitor, which incidentally can only work at 640x480.
If the monitor is a single-frequency model, then you will only have the one resolution available. If you want to use different resolutions you will need to get a multi-frequency monitor. Virtually any multi-frequency monitor will work, but if you want to use the 7100�s built-in video port you will need an adaptor if the monitor is a standard PC one. A couple of clarifications � the 7100 can have one or two video ports provided as standard. One is built-in to the motherboard and has relatively low performance and resolution. The second is provided on a card which is plugged into a special slot. This card provides higher performance and resolutions. The card is not present on all systems (it was an option when they were new), although most do have it. If the 7100 has been fitted with a CPU upgrade this fits in the same slot, but some upgrades allowed for a pass-through device which enabled the fitment of both the CPU upgrade and the video card, although this was somewhat of a bodge. Secondly, the standard video ports on the 7100 have 9 pins (in two rows). The standard PC SVGA connector which is fitted to all PC CRT monitors has 15 pins in three rows. There are many sources of adaptors which convert between the two, although things are slightly complicated (aren�t they always) by the fact that the way in which the plug is wired tells the computer what resolutions the display will support. The better adaptors have little switches on them which allow you to set the adaptor up to tell the system which resolutions are available on the monitor. Adaptors without switches generally are set to a fixed setting which may or may not be appropriate for the requirements of a particular Mac/Display combination. Sorry the above is a bit involved, but that, unfortunately, is the way it is!

I have a 7200/90 with an Apple Display Monitor, with only one resolution, 640 x 480, 67HZ. There is no choice. I recently downloaded Sigma Chess but cannot play it on this monitor for it requires a higher resolution 800 x 600. Is it possible to increase the resolution preferrably with some software. 2. My modem is connected to the serial port. How can I add more devices without discoennecting the modem? Is it possible to create usb support.
