.. I need to get a monitor, not necessarily ofr an Amiga, and so far the contenders are Nec's multisync or one of the Sony KVxx series (probably a 13"). I would appreciate hearing from people as to which they consider the "best". News is not particularly reliable at our site so please reply by email and I will summarize the replies I get. If anyone has alternatives to these monitors in the same sort of price range I would be interested in that too. One concern I have about the multisync is that (according to a NEC rep. I talked to at siggraph) the rgb signals must be in the range 0-0.7v - standard rgb is 0-1.0v it seems to me so is this a problem? thanks in advance, john *** REPLACE THIS LINE WITH YOUR MESSAGE *** -- {watmath,seismo,uw-beaver}!ubc-vision!fornax!sfulccr!chapman or ...!ubc-vision!sfucmpt!chapman

Actually .7 volts is standard for analog RBG and 1 volt is standard for composite video. Actually composite has about .7 volts of video and .3 volts sync, but let's not argue about that. Most monitors are able to cope with a fair range of voltages via their brightness controls. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

The Sony KV13XBR is a very nice monitor for the Amiga. It is an NTSC format, rather than multisync type of monitor. The Sony has the advantage of Being an RGB analog monitor in addition to a TV set with a remote control, thus enabling you to watch Max Headroom when you need a break from programming (grin). You might try BTE electronics (see ad in Computer Shopper, for instance) for a source of Sony monitors. The KV13XBR monitor will not work with your EGA card. You'll have to make up your own cable to connect to the Amiga with either the Sony or the NEC multisync. The connectors you need vary according to monitor. I'd consider asking if the dealer can make the cable for you, thus saving some bother. The NEC Multisync is not a bad monitor. I've had experiences with 8 of them so far. The oldest NEC (in my office) has been running 8 hrs. weekdays for the last year. There is a wide variation in quality on the NEC multisyncs, though. You never can be sure what you'll get. The best NEC multisync I've seen comes very close to the Sony CPD-1302 (which by the way, is the best multisync monitor that we have encountered in the 13-14 inch class). The CPD-1302 will set you back $750, which is outside the range you specified. The worst NEC we got came with a tilted yoke; another came with a very out-of-focus picture. I was able to adjust both to acceptable perfomance- an annoyance to have to do that on a brand new monitor, however. The NEC also requires quite a bit of fiddling with the position knobs as it switches between modes, especially CGA --> EGA480. Sony and Taxan multisyncs have more sophisticated auto positioning circuits. I have to say one thing about the CPD-1302. It uses typically inscrutible oriental design. Like many Sony products, there is an amazing amount of electronic stuff inside. It looks like there are enough components to build three normal monitors! The NEC multisync does its job with fewer components. The NEC also switches electronically, and has no clanky-sounding relay when it changes sync modes. I suppose that simply becuase it has more parts, the Sony CPD-1302 would be more likely to fail, although our experience hasn't borne that out. We were able to get the shop manual for the CPD-1302 from Sony, but it did take two trys-- the first manual we received was for a NEC Spinwriter that is sold with a Sony label on it!!! (It has a similar part number to the monitor's manual.) NEC hasn't dug a shop manual up for us yet. I have not seen the insides of a KV13XBR, but the performance of other Sony products suggests that it would be alright. The NEC multisync has an anode voltage of ~40 KV for the screen. The Sony uses around 30 KV (forget the exact value at the moment). NEC claims that the high anode is an advantage, but that doesn't seem true. Our experience is that higher anode voltages do increase brightness, but also tend to increase pincushioning and degrade focusability of the beam.
