- I looked very hard and long at 20" monitors. The only decent review that I
- found on these monitors is an article in PC/Computing, March 1992, p. 197,
- in an article on "In Search of the Ultimate PC". The author ended up in
- picking the Taxan Ultravision 1095. He would have liked the Nanao T660i
- except that his video card did not fill the screen completely at 1280x1024.
- Despite that, the December 1992 issue of PC/Computing p. 188) gave
- the Nanao T660i its top award for a monitor (".... the T660i is simply
- the best 20" high-resolution monitor available."). The runner-up 20" monitor
- in this issue was the Philips FastRefresh/20 (about which I know nothing).
-
- In December I bought a Gateway 486DX2-66V local bus machine, with
- the ATI Ulra Pro with 2 Megs VRAM and the upgraded RAMDAC, and
- the Nanao T660i.
-
- That combination works great, in all resolutions, and the sceen is filled
- completely at all these resolutions (all 19", which is the maximum viewable
- area on this 20" monitor; the rest is masked off). Here are some synch
- values which I ended up with during the Install process of the Mach 32
- card (all numbers are non-interlaced):
-
- 640x480 96Hz 40MHz option (8bit)
- 640x480 72Hz 32MHz option (more colors???)
- 800x600 75Hz
- 1024x768 81Hz
- 1280x1024 77Hz
-
- Between the adjustments on the video card settings, and the adjustments on
- the monitor, there are probably a number of other frequencies that will also
- give you completely filled screens. There are also pincushion and trapezoid
- adjustments, so the picture is absolutely square, right against the mask edge.
-
- >How important is maximum horizontal and vertical frequencies, as well as
- >bandwidth?
-
- Probably very important, in terms of flicker. But I can't see any flicker
- even when adjusted to a low refresh rate (60Hz, non-interlaced).
-
- I had done some calculations on bandwidth. I figured that you need at least
- 120 MHz at 1280 lines, and 160 MHz at 1600 lines. The bandwidth of the
- T660i is 120 MHz, so it's enough for 1280 lines.
-
- >Can you hook up BNC cables to the ATI Ultra Pro video card on a Gateway?
-
- The ATI Ulta Pro only has the usual D-Sub connector. There are no BNC
- connectors on that card, and the cable that came with the monitor is the
- usual video connector cable. My guess is that this combination probably
- won't deliver 120Mhz to the monitor. I have not seen any comments on the net
- on whether switching to BNC connectors makes a difference. Just for
- information: the T660i also has 5 BNC connectors on the back, in addition to
- the D-Sub connector, and a switch on the front chooses which signal lines
- the monitor should use. Looks like the monitor could be run from two separate
- video cards.
-
- >Any recommendations for mail order firms for monitor? Any to avoid?
-
- Look in Computer Shopper. There are only a handful of places that sell the
- "big" monitors. I bought mine at CAD Warehouse in Ohio (Cleveland area).
- Call 1-800-487-0485. I dealt with David Hoffer, who seemed quite well
- informed and quite straightforward. Ask for a price, first, though. I ordered
- mine in December, and had it 3 days later. Price: $2475 plus $49 for shipping
- (via a trucking company - the box was 100 pounds!), exactly what I was told
- on the phone. This is the second monitor I have bought for CAD Warehouse (the
- other one in August), and I am quite satisfied with the company.
-
-
- >Nanao F750i 21" 0.31mm
-
- This monitor has a bigger screen, but a more conventional tube. This tube
- is not as bright as a trinitron tube (noticeably dimmer, at least judging
- by its smaller brother, the F550i, which has the same kind of "flat" tube).
- The latest price from CAD Warehouse for the F750i is $2090 plus shipping
- (Feb 93, Computer Shopper). The big killer here is that the maximum
- horizontal synch frequency is only 65kHz (compared with 80kHz for the
- T560i and the T660i), which translates to a maximum refresh rate
- at 1280x1076 of only 60 Hz. For a big-size monitor that's a serious handicap,
- because your peripheral vision may be bothered by the flicker. I seriously
- considered this monitor, and then decided that it would do properly
- only 1024x768.
-
- Re screen flatness: the T660i is absolutely flat vertically, but has a
- horizontal curvature. Despite that curvature, the screen appears flat when
- you look at it. Re the horizontal wires: yes, they are there, but in
- most cases they don't show up. When they do show up (white background),
- they are very faint and easy to ignore.
-
- The bottom line? I love my T660i. It does everything right. What else can
- I say. Yes, I really splurged on the T660i. It was a hard decision to
- spend that much money for a monitor. But now I am happy that I did. Windows
- never looked better.
