According to MacTracker, the card should have ADC and VGA connectors.
ADC is "Apple Display Connector", which is a proprietary Apple one based
on DVI, but using a different connector shape and including additional
signals (USB and power for the display). You aren't likely to find any
non-Apple displays which plug directly into this.
There were adapters to convert ADC to a standard DVI connector, which
you can probably still get from somewhere. I was able to pick one up at
a local Mac dealer three or four years ago but I haven't seen any since
then. Somewhere like Other World Computing < http://www.yqcomputer.com/
likely to stock them.
If you can locate one of these adapters, the resulting DVI port is
likely to produce a slightly better quality image than VGA (by avoiding
a couple of D/A and A/D conversion stages).
VGA and DVI should be compatible with any current computer monitor you
want to try. Nearly everything I've seen in the last couple of years
supports both of these as inputs.
The maximum resolution of the GeForce2 MX is likely to be 1920x1200, but
I don't know whether that specific card will work at other aspect
ratios, such as 1920x1080 ("Full HD" for a modern TV).
For a combined TV and computer display, the VGA port is likely to be
easier to use - just look for a TV with a VGA input port and associated
audio input for the computer.
Most modern flatscreen TVs use HDMI, and you can get a DVI to HDMI
adapter or cable, but daisy-chaining adapters starts to get messy. You
would still need a separate audio cable, and the TV would have to
support separate audio input with one HDMI port.
An older TV with composite/S-Video/component inputs and no VGA input
will be harder to deal with. Some kind of video converter would be
