Lines: 46 Xref: watmath net.video:959 net.micro:9349 Summary: Although I missed the beginning of this discussion, there are some points raised in this article which are of interest to me. I have been considering getting a monitor (without tuner) as a TV set and using the tuner to a VCR (other?). The implications are not all that clear to me.

I recently saw a NEC hi-res monitor (don't remember the model), sans tuner, with RGB, NTSC and VTR(?) inputs for $425. After watching some local TV on that for a while, I was very disappointed in the picture on the high-dollar Mitsubishi TV's. I don't know what they were using for a TV tuner. Would one get as good a picture using a VCR tuner to supply the input ? (The next pt in this referenced article seems to hint "no"). > We won't even discuss colour under VCR's here.

How much does a fine TV/tuner amplifier cost ? I would appreciate any help here. -fitz lef@nlm-vax
