That's great. Apple sold millions of those tiny 12in monitors, but at the same time did not write into the monitor control panel how to access them on a Mac II video cards. In fact many of them came for "free" with a purchase of a Performa 400 and 425 (Mac LC/LCIIs). They were not free, it was part of the price as a package deal. They were optional on the IIgs and IIc's.
What kind of video card is it? the 8Bit card "High Resolution Display Monitor Card" or the 24bit video card? That high resolution card does 640X480 at 256 colors nicely, but its a fixed resolution. The 24bit video card has more resolution options and the one best for the IIfx. (It's best for any Mac II...) The others (like the LCs, IIci, IIsi and so on) the resolution depends on how much VRAM is put in and in the case of the IIci/si you can put in video card in them as well and they would run better. Their resolutions start at the 512X384 level for that tiny 12in monitor and goes up from there, again depending n how much VRAM is in the system.
Good luck.
BTW - somewhere on this forum is my attempt at recapping my IIfx. It was surprisingly simple as I only replaced that 1 leaky cap I found on the board though I thought it was 3 caps. Having Tantalum Caps already in them, that IIfx is going to last longer than most Macs! I bought black Tantalum Caps to match the others. It was a bit pricey but god does the board look good!
My mistake, it's 2 of those leaky caps on the right side of the board. Now I remember, my daughter recapped this board as I was in the hospital from a bad effect of the medications I was taking then but I was going to do it though she did it for me. The thread is here:
