But I don't see much about grayscale viewing - so here goes . . .
I request guidance in regards to 19" SXGA (not widescreen) LCD monitors that would be good for grayscale viewing.
I understand that the best my poor old video card (a PCI ATI Radeon 7500) can put out is 8-bit grayscale, so an 8-bit LCD monitor (256 shades of gray) should be a good match. A 6-bit LCD monitor, which is what I have now, only gives 64 shades of gray - this is insufficient for what I would like to be able to do.
My intention with the new LCD monitor is to view conventional grayscale x-ray images at home for educational purposes. Teaching files and the like.
Not for actual diagnostic work - 10-bit (1024 shades of gray) to 16-bit (65,536 shades of gray) monitors are used for serious grayscale imaging, but they tend to run a little bit higher in price than what I have in mind for a modest home computer setup.
Other than that, the monitor will be used for nothing more demanding than web-surfing, email and word processing. No gaming, no photographic work, no DVD watching - so the monitor can be slower than cold molasses (by gamers standards, anyway). I much prefer the 5:4 aspect ratio of the basic 19" 1280 X 1024 SXGA LCD monitor over a widescreen aspect ratio. The larger pixels of a 19" 1280 X 1024 monitor are also a plus for me - I need glasses to read print well and I tend to view a monitor at a distance of about 21". Glare-resistant screens are a plus - I find the reflections in glossy screens to be distracting.
I have already learned a considerable amount about LCD monitors from this thread. I would greatly appreciate further guidance in regard to my own situation.
Thank you,

For you, the NEC LCD1970NX (avoid the LCD1970VX which is a TN) looks like a good choice. It contains an 8-bit (256 shades per channel) S-IPS panel, albeit a slightly aged one. The LCD itself is of good quality (like all NECs). Street price is $389.99, and this sounds like a good place to order from:
B&H - NEC LCD1970NX
It may use the updated LM190E05 panel from LG Philips LCD. Whatever the case, I am pretty certain it's a true 8-bit panel. Image detail and contrast should be great with an S-IPS panel.
If/when you want to upgrade to 10-bit, I think ATI's 10 series (Xxxxx) graphics cards and NVIDIA's 8 series support 10-bit output. You'll have to decide if it's worth it to invest in a 10-bit setup now or not. If you do, keep in mind 10-bit LCDs are actually 8-bit LCDs with smarter dithering algorithms. There are no true 10-bit LCDs to my knowledge. (Maybe one of those $6000 NECs has it.)
Xtknight,
Thank you for the suggestion.
Before ordering the NEC LCD1970NX, I went ahead and checked out the NEC web site. I found that the information that I need to make a decision - 6-bit vs. 8-bit, glossy vs. reflection resistant - was entirely missing in action from the web site.
Strange.
I then found myself chatting with a gentleman from NEC tech support. He seemed to know his stuff. I don't suppose that I should paste the entire conversation, but let me give you the relevant content:
He stated that "the 1970NX is 6bit+FRC." I repeated the question in a couple of different ways - did they use different panels at different times? - I have seen sales literature suggesting that the 1970NX is 24-bit, 16.7 million colors, could he comment on that? - etc. He indicated that NEC cannot control third party content and that "the 1970NX is 6bit+FRC ."
Fair enough.
For my purposes, he recommended the 1990 line. To add to your data base:
1990FX - 8-bit gamma, 24-bit, 16.7 million colors, 250 cd/m2, 800:1 contrast, 178 degree viewing angle, 18ms typical (14 ms G to G), 3 year warranty. $450-$500 delivered (as per Pricegrabber).
1990FXp - 8-bit, 250 cd/m2, 1500:1 contrast (1500:1 contrast?!), 178 degree viewing angle, 20ms typical (8 ms G to G), 35 Watt, 3 year warranty. $540-$600 delivered (as per Pricegrabber). The "p" denotes PVA panel technology.
1990FXi - 12-bit gamma, 270 cd/m2, 600:1 contrast, 178 degree viewing angle, 18ms, 4 year warranty. $675-$700 delivered (as per Pricegrabber). The "i" denotes IPS panel technology - "the best of the best" as per NEC tech support - (time for me to review your original post about which panel is which). It has all sorts of technology to provide uniformity in regards to the viewer's perception of the backlight and for optimal grayscale. This would be the ONE - if I was going to spend that kind of money on this project. But I would prefer not to.
Glossy vs. reflection-resistant screen?
Both the 1970NX and the 1990 series are considered business-class - all the NEC business-class monitors are non-glossy. The consumer monitors with the glossy finish have "G" in their names.

OK - any suggestions as to another 8-bit 1280 X 1024 19" SXGA LCD monitor that might do 256 shades of gray?
Another manufacturer, perhaps?
I'll do the gum-shoeing if you can steer me in a likely direction.
I was hoping for something in the $300-400 price range. The thought when beginning all this was, "if I am going to get a new LCD monitor anyway, I might as well get one that does good grayscale." Heck, I was just going to get a Dell.
Then I saw your thread.
Looks like reading your thread may cost me some money . . .
Thanks, again
