- Subject: Submission - Color Monitor Review
- Date: Fri, 17 Apr 1992 14:49:01 GMT

-
-
- The following review of large color monitors may be of some interest. I visually evaluated a number of 16"-21" Multisync monitors for the Quadra.
- ---------------
-
- What I did on my Spring Break....
-
- (A wholly biased survey on Large Screen Monitors for the Mac)
-
-
- Background:
- -------------
-
- I was looking for a large (19-21") multisync monitor for my new Quadra 700.
- After an initial look at the offerings in the traditional Mac World - I
- decided that I would get a CAD-grade Multisync monitor directly from a
- monitor manufacturer. I have worked with monitors on an OEM basis for many
- years and am comfortable with the technology. I also know that the is
- generally a way to get higher quality at the best prices.
-
-
- Advantages:
- The big advantage of a multisync is that I will be able to run it either
- at 1152x870 in 8-bit mode or 832x624 in 24-bit mode from my Quadra. I can
- also move the monitor to another system someday should I be so inclined.
- Microprocessor controls are also nice - allowing adjustment of picture size,
- distortion correction, etc.
-
- Disadvantage:
- Most of these OEM's deal with the PC world (Although they are becoming Mac
- aware quickly) Many cannot supply a MAC cable. All use BNC inputs - so any
- Mac 21" cable should work. I plan to make my own by changing the 15 pin
- connector on a VGA cable. Note that many PC-oriented moinitors say that
- they will display 1280x1024, but they have a maximum horizontal scan rate of
- 64KHz. The Mac wants 68.7KHz for 1152x870.
-
-
-
- I went to the CEBIT show in Hannover, Germany during spring break and spent
- a day evaluating monitors. These were European models - but almost all are
- available in the U.S. Note that these may have been hand selected units for
- display - but I saw several units of most brands. Many units were displayed
- by users, not manufacturers. Also - be forewarned that German distributors
- have very high quality standards and will not tolerate a great deal of
- variation among units, thus they may not get as many duds as we do here.
-
-
- A general observation: There is a great deal of variation among units that
- would seem to be similar. Particularly - Trinitron monitors which use the
- same tube can vary significantly in quality. The best Trinitron monitors
- are among the best available - but for a better price - standard tube units
- provide almost as good quality. The worst Trinitron units were definitely
- worse than the best Shadow Mask Tube units.
-
- This can actually be explained in a rational manner. The market for
- standard tube CAD monitors is large, large enough to show some notable
- economy of scale. Unlike the mass market for 14" units though - they are
- used by professionals who are quite critical. As a result - there are
- excellent units available. My overall recommendations follow my comments on
- individual units. If you make it to the end, I'll tell you what I bought.
-
-
-
-
- My Comments:
-
- Apple 21" Color
- ---------------
-
- 1152x870 resolution only. Flat/Square Tube. .26DP
-
- I only noticed Apple itself using this monitor. Many were quite good but
- several had serious convergence problems (color fringing). Some were out of
- focus. No Multisync and mucho expensive. (My educational price ~$3k).
-
-
- Apple 16" Color
- ----------------
-
- 832x624 resolution only. Trinitron Tube. .25DP
-
- Very bright. Good Colors. Not the sharpest trinitron - but OK. Very large
- for a 16" screen. (16" tubes seem to vary quite a bit in size - the
- Trinitrons are quite large). ADB Ports. Quite a nice unit - but not enough
- resolution for me. (My educational price $1040).
-
-
- NEC Multisync 5FG, 6FG
- ----------------------------
- 640x480 -> 1280x1024 Flat/Square Tube. .28DP
- resolution including all Mac Modes
-
- These are the flattest units I have ever seen - but it may be an illusion
- caused by the bezel. They can display all the way to the bezel edge for a
- large viewing area. Colors are quite good and brightness is good - but not
- as good as the Apple 16". I saw over 20 of each of these. I found all of
- the 17" units (5FG) to be critically sharp, but almost all of the 21" units
- (6FG) have some misconvergence or lack of sharp focus. The 5FG is an
- excellect choice if you want to run 1152x870 mode on a smaller screen.
-
- Nanou Flexscan T560 (Eido? in Europe)
- ---------------------
- 640x480 -> 1280x1024 16" Trinitron Tube. .25DP
- resolution including all Mac Modes (Maybe 1600x1280 as well)
-
- This guy is spectacular. The Sony 16" tube with perfect display quality. I
- only saw the manufacturer's units - but I saw 10 of them. These work on PC,
- Mac, Sun, SGI, etc. The bad news... The price. About $1800 mail order in
- the U.S.
-
-
- Nanou Flexscan T660 (Eido? in Europe)
- ---------------------
- 640x480 -> 1280x1024 20" Trinitron Tube. .30DP
- resolution including all Mac Modes (Maybe 1600x1280 as well)
-
- As good as the T560. Spectacular 20" Trinitron. About $2800 Mail order.
-
-
- Hitachi CM2087/CM2187
- -----------------------
- 640x480 -> 1600x1200 20" Spherical Tube .31DP or
- 21" Flat/Square Tube, .31DP
-
- Supports all Mac Modes
-
- These are real live CAD monitors from the old guard. They are designed for
- people to stare at all day long. They are sharp and have reasonable colors.
- For advertising, I would prefer the brighter Trinitron units, but for
- everyday detail work such as DTP or CAD - these are excellent. Logitech
- chose to use the CM2187 for their virtual reality demo. These have all the
- features one would like to have on a non-Trinitron monitor, Invar shadow
- mask, Dynamic Beam Focus, Anti-glare coating, microprocessor controls...
- The CM2087 may be the bargain of the year. It pops up in Computer Shopper
- for less than $2K. (Maybe even $1800). It is a quite good unit. Some
- documentation says that the 20" cant do better than 1280x1024 - but it
- doesn't match with other spect. I think it's just product differentiation.
- The CM2187 adds a slightly larger Flat/Square tube and better anti-glare
- coating - but at a price ($2500 or so). Hitachi monitors are distributed in
- the U.S. by Nissei Sangyo America.
-
-
- Hitachi America
- ------------------
- Hitachi America distributes another line of Hitachi monitors, the Accuvue
- and Superscan series in 20 and 21" units. They seem to use the same tubes
- as the NSA units and are close in quality - but the have a few less features
- and cost about the same. I preferred the NSA units.
-
- can't do any better in this class. Price - about $2800 discount.
-
- Idek MF5321, MF5421
- ----------------------
- 640x480 -> 1600x1280 21" Flat/Square Tube. .26DP
- All Mac Modes
-
- The MF5321 is a .31DP and can only go to 1280x1024.
-
- These are top quality units used by many CAD pros. They are consistantly
- high quality. Very comparable to the Hitachi CM2187. $2400-$2800.
-
- Ikegami CT-20V
- ---------------
- 59-81KHz Hscan 20" Trinitron Tube. .30DP
- Limited scan range - includes 1152x870 only
-
- This unit was as good as the best of the Trinitrons. I was told (but not
- shown) that the CT-20A was a full multiscan unit that was comparable. I was
- warned that there were American units called CT-20 that were not up to the
- same quality standards.
-
-
- Mitsubishi Diamondscan 16L, 20L
- -------------------------------
- These were only mediocre units with traditional tubes. I was unable to
- confirm that their scan rates were adequate for a Mac.
-
- Sony CDP1604
- --------------
- 640x480 -> 1024x768 16" Trinitron Tube. .25DP
-
- A reasonable 16" Trinitron. Low cost (I have seen it for $999).
- Not quite as sharp as I would like - but close. Doesn't do 1152x870 mode.
-
- Sony GVM1936
- -------------
- 640x480 -> 1280x1024 20" Trinitron Tube. .30DP
- resolution including all Mac Modes
-
- I was routinely disappointed by this unit. (note the 1604 is called the
- 1704 in Europe and the 1936 is the 2036). For some reason, this was not as
- sharp as the Nanou, Taxan, or Ikegami. Many jittered as well. I saw a
- number of the Sony units - including those shown by Sony - and none were
- perfect.
-
-
- Taxan UltraVision 1150
- ----------------------
- 640x480 -> 1600x1200 21" Flat/Square Tube. .31DP
-
- This is an excellent unit - with one disability. It is not a true multisync
- - but rather a sort of 'several sync'. It will work in 1152x870 mode or
- 640x480 mode or SVGA mode - but not 16" mode (832x624). Very sharp picture,
- Very good colors, no pincushioning or other distortions. (Note: I only saw
- one.)
-
- Taxan UltraVision 1095LR
- ----------------------
- 640x480 -> 1600x1200 20" Trinitron Tube. .30DP
- All Mac Modes
-
- Spectacular! As good as the Nanou. Great controls with LCD display. You
-
-
-
-
- Summary:
-
- The very best units were the top Trinitrons. They were as sharp as the best
- FST units and somewhat brighter with better colors. The Nanou T660 and the
- Taxan 1095LR stand out as the best. The Ikegami is as good if you can figure
- out what you are getting. The Sony does not measure up.
-
- The Hitachi CM2187 and the Idek MF5421 are the next best in quality. They
- provide slightly larger screens than the Trinitrons, Lower prices, and
- better anti-glare protection. They are also somewhat easier to find due to
- their popularity in the PC CAD market. The Hitachi CM2087 is not quite as
- impressive but it may be the value leader.
-
- The NEC 5FG and the Nanou T560 are the best 16/17" units. The NEC has a big
- price advantage. The 6FG has a big display area - but it does not quite
- match the 4 units above that I like better.
-
- Sony - my favorite for public display use - got a thumbs down for the
- desktop.
-
-
-
- My choice - I ordered the CM2187 from Hitachi. My hope is that purchasing
- can squeeze one out for less than $2400.
