LACIE 324i LCD DISPLAY

For too long there have been few LCD displays available that fully support a digital photographic color managed workflow. Now LaCie has added another, their 324i with desirable specifications in a P-IPS 10-bit 24 inch LCD display. The screen image should be sharp and detailed too with a 1920x1200 pixel resolution. Most important of course is its color range that is specified at 98% of Adobe RGB. But these days with ultra-lite and flimsy un-adjustable home-office LCD displays in the box stores, the LaCie 324i has a solid, full-featured stand and supports portrait orientation. Like any good, current LCD display the LaCie has a wide range of input connector options like Display Port, DVI and HDMI.

Other important advantages include the display’s support for on-board calibration adjustment, and as La  Cie has done in the past, professional options include a hood made and designed for the display as well as La Cie’s own Blue Eye calibration and profiling software and colorimeter. Unlike some professional LCD displays, the LaCie displays are not limited to their own software and colorimeter, either X-Rite, DataColor or ColorEyes Display Pro will work effectively if a buyer already has them. But with such a wide color gamut the La Cie will need a current type-2 colorimeter that can accurately read a wide color range.

I don’t plan to test and do a full report on this new La Cie 324i LCD display, but I have tested and found La Cie displays are exceptional, and bought one for my own use five or six years ago and it is still providing fine performance. My only reason for just doing this brief report is the La Cie is on the high side of the price range at $1249. A very complete description and all specification for the 324i is on the La Cie web site at: http://www.lacie.com/us/products/product.htm?pid=11570

DREAM

That the one piece of equipment I dream of is an ideal LCD display should not be a surprise. It is what I have been most concerned with of late. And it is also what I look at most to see my photographic images.

However what I dream of is not some exotic, superior new level of device performance at all, but one that is inexpensive and is based on already existing technologies that could be put into a very affordable LCD display. In other words I am dreaming about something that would work well for anyone using a computer to do digital photography editing and processing.

Why such a display is not on the market presently is in part because customers have not demanded it, mostly because they are not that aware of what they need, nor are they aware of what the contemporary industry could produce. Another reason is that the graphics computing aspect of the technology industry is a mix of unrelated items, much of which is controlled by sometimes different, alien and contrary items. LCD displays are not made by companies that make computers. They are made by companies whose largest market is the home television and similar kinds of display devices that have no dependence on computers to function. So LCD displays for computers are just slightly modified TV displays, and what works best for computer users is very likely unknown to the scientists and engineers who create the LCD displays.

So, exactly what do I have in mind? It would be an LCD display like many now seen in stores that sell computers. It wold be the largest size that sells at competitive, affordable prices with a 22 inch diagonal in HD format with a 1920 by 1050 resolution. It would be different in some very important senses, first that the maximum white luminance brightness would be half of the usual 250-300 CD/M2 that is currently popular. This would be accomplished by reducing the brightness of the backlight. The backlight source would be white LED lamps, because they are efficient, uses less energy and remain consistent for a longer period of time. The color gamut would be slightly greater than 90% of the size of the Adobe RGB (1998) color profile, a feature that is not uncommon today and has been offered in a lower-cost affordable brand of LCD displays recently.

What would be most different is that there would only be one control with two settings, a bright setting that would provide a white luminance of 120.0 to 140.0 CD/m2 and would be intended for normal office/home computing use. The second setting would be a lower brightness with a white luminance of 90.0 CD/m2 for digital photography image editing and processing. At this setting the standard parameters for computer video would be applied of color temperature of 6500K and a gamma of 2.2. But in addition the display would be factory calibrated and profiled to achieve a neutral gray, and both the calibration file and profile would be fed to the computer through the DDC channel of the DVI interface connection.

In other words this LCD display would do well both for most home/office computing and by simply click of a switch to the “photo” setting would provide a consistent, reliable adjusted, calibrated and profiled parameter for color managed digital photography editing and processing.

I believe with an LED backlight lowered to half of the present LCD display level using the LED source the “photo” setting calibration and profile would remain sufficiently stable and within a range that would be effective for all serious digital photography needs for an extended use period. The display would be “self” adjusted, calibrated and profiled to be effective in a color managed image computing environment without requiring any user adjustment, sensor testing and profiling, or any additional expense.

I would particularly like to see Apple Computer make such an auto profiled LCD display available for both Apple computers and PC Windows computers as well, it could be another Apple sales success. But more important, combined with the Apple Mac Mini it would be an ideal digital photography computer setup many users could both afford and enjoy the best digital photography editing and processing experience.

I GOT LUCKY!


No my sex-life has not improved. I haven’t been looking for a new squeeze. But I have been looking for an inexpensive LCD display that will work for digital photographers. Actually I discovered it among numerous models LG Electronics has listed on its web site awhile ago. But a request to LGE for a loan to review it for Shutterbug was denied because it is a 2008 model that is not being offered in the 2009 product lineup.

The model is a L227WTG, a wide screen 22 inch, wide gamut, with 1680X1050 pixel resolution using a (TN,IPS) panel, with a 2MS response time, and a pixel pitch of 0.282, with a recommended price of $360. I have seen this model LGE advertised by a number of on-line vendors like NewEgg, Amazon and Tiger Direct usually under the price listed by LGE. The other day I saw a price of $219 plus shipping and I could not resist, although I have no need for another display. It was delivered a couple of days ago.

The next morning I had it unpacked, and installed on one of my systems in about 15 minutes. I turned the system on along with the new LGE display, and went for my second espresso of the day while it warmed up. After answering a couple of e-mails, I went back to my lab and proceeded to adjust, calibrate and profile this new LCD display using ColorEyes Display Pro and a DataColor Spyder3 colorimeter. With the ColorEyes application on-screen the first item is monitor setting, selecting what kind of display you are connected to, so I tried the top selection for DVI-DDC displays, and after waiting just a bit the software confirmed that the connection had ben made and there is support for DVI-DDC that allows screen adjustments made via ColorEyes as part of the process of calibration and profiling. (I didn’t have to deal with manually adjusting screen contrast and brightness controls the software did that to the 90.0 CD/m2 aim point I selected in the CEDP software application, along with the selection of L* Gamma, and a color temperature of D65. With all my aim points selected, I clicked on the Profile button and sat back while ColorEyes did its work; almost half an hour and this was on my fastest computer.

But it seemed worth it. Once the calibration and profiling was done I re-started the computer and checked to be sure the new profile was now set as the boot default. With a largely blank medium grays desktop the gray was neutral and even across the screen, at least as even as any display I use with CCFL tube backlight. Then I launched Photoshop and opened my standard personal print test image. There was nothing in the display image reproduction I could find any fault with, but this display has its own look. That may be in part due to the fact it has a much shinier screen surface than I am used to, but nothing like the glass mirror finish of the new Apple iMacs and 24” Cinema display. I wasn’t concerned at this point as every new display I test takes getting used to perceptually. So I set about color correcting and adjusting Raw camera files from a recent shoot. I soon felt fairly comfortable with this new display, and after finishing a good number of files I did some color managed prints to see if both color and density matched what was displayed on-screen. Not bad at all. A little varied but learning how to anticipate results with a strange new display takes more than a handful of processed images. I expect to have it zeroed in after a couple more days living with the L227WGT, and I also expect I will like this display even though I am not a fan of wide format sizes and screen proportions. But that’s all there will be in the future as new 3:4 aspect ratio displays are being discontinued at a rapid rate.

The 3rd day with this new LGE display, and many more images color corrected and adjusted with increasing accuracy and ease. So I decided I should be sure of this experience and move the display to my least powerful Mac Mini computer, and re-calibrating and profiling the display. That proved to be just as accurate. And I will take advantage of my use including e-mail and writing at the lower display resolution, 1680X1050 with a 22” provide larger font display, versus a 20” with 1600x1200 pixels. As I have said before I like the older 20” displays and their high resolution, for the sharpness and its advantage doing retouching.

The bottom line is that this L227WGT display provides the essential attributes of a large color gamut, most of Adobe RGB, DVI-DDC support for more beneficial adjustment to achieve a brightness match to photo inkjet paper white, about 90.0 CD/m2 white luminance, as well as accurate calibration and profiling. This performance supports screen to print matching in both color and print density. However, even though the screen appearance is as good as more costly LCD displays, the affordable price is achieved in part by very light weight construction and limited adjustment capability, particularly this display cannot be raised or lowered, as well as only two connection inputs, a digital DVI interface and an analog D-sub connector for older computers.

How many of these LGE L227WGT displays remain in stock and available for purchase is unknown, but it is limited number and will not be increased by LGE as this model has not been continued in 2009. So, if you want a very affordable display that is an effective solution to avoiding prints that are too dark, get on the Internet and make your search for an advantageous price.

LCD DISPLAY BEST BUY

I was at least subliminally aware of LG Electronics between 2 and 3 year ago when I searched through their LCD Display offerings and decided to purchase one of their Flatron L2000C 20 inch displays. At that time in America LG Electronics was a barely known brand name, but has gotten more cache in the last year or so, but mostly for cell phones and TV’s, and little awareness in the LCD display market for computers. Since I purchased my 20 inch LGE display I have acquired two more different brands and tested and reported on several more, including LaCie and Eizo, both of which are familiar brands only in the niche pro-graphics market.

When I am asked for recommendations of LCD displays (a frequent occurrence), I usually include the LGE L2000C as my experience with it using it daily for well over two years now has been good, and the performance so close to that of two to three times as expensive more highly touted brands that I’d buy and use nothing else but the LGE were I to begin again and know what I know now. Yes, the most expensive professional displays do have a larger color gamut, but it is neither that big a difference or that significant an advantage that it is a must have attribute, especially at such a much higher price.

But why am I now singing the praises of the LGE Flatron L2000Cp, my display’s current model designation? First of all I got a Consumer Electronics Show news release about a new line of LGE LCD displays that were announced. Then I got an Apple Computer news item in my in-box announcing that an agreement was signed between LGE and Apple amounting to Apple’s payment (in advance) some $500 million dollars to secure an ongoing supply of LGE LCD display products. Interesting news because it confirms to some extent a long standing rumor as to the source manufacturer of Apple’s displays. Anyway, my interest was piqued so I got in touch the LGE’s PR agency, and the ensuing exchange revealed another bit of information I found interesting and answered why LGE L2000Cp displays are sold by so few of the typical sources for LCD displays. LGE does not consider the Flatron L2000C model a consumer product, but a business product that they usually expect to sell directly in large lots. And by the way LGE is the second largest manufacturer of LCD displays. How can that be you might ask, and the answer is that LGE has been an OEM supplier and they manufacture LCD displays sold under many brand names.

So, the one source I purchased from and I have pointed others to because they have been one of the few with LGE Flatron L2000Cp 20 inch displays in stock rather consistently, is Amazon.com, I just checked Amazon’s web site again. And the site indicated availability, and a list price of $732.26 with Amazon’s price of $402.48. Now that is really a best buy. And, Oh! The new LG displays announced at CES are not intended to replace the Flatron L2000Cp, they’re consumer models.
