By Terence Curren
LCD Reference-Grade Monitor
JVC
$4,695
DV Score:
Pros:
Great color rendition. Rich blacks. Clever use of extra space for data display. Rotary knobs for fine-tuning adjustments. Reasonable price.
Cons:
Standard-definition video still not as good as a CRT.
Bottom Line:
If you need to purchase a reference-grade monitor today, this would be it. If not, wait for NAB to see what new technologies arrive.

CRT is dead! For many of us that's a tough pill to swallow, but it's true. So where do we go from here? Plasma, LCD, or the upcoming OLED and SED technologies are the answers. I've been checking out every professional option that has debuted in the last two years, so I jumped at the chance to review the new JVC DT-V24L1D LCD monitor.
LCD: a little background
Problems with LCD technology in the professional video space have included lower resolution, lower contrast ratios, visible lag on motion, reduced viewing angles, substandard color matching, and washed-out blacks. While most of these issues have been resolved in all but the cheapest of LCDs, color matching and richness in blacks have remained elusive in any LCD under $10,000.
Products like the eCinema DCM23 and Cine-tal CineMage were the closest we could get to the look of a reference-grade CRT-until 2005, when Panasonic introduced its first low-cost professional LCD monitor, the BT-LH1700. While good enough for field reference work, the Panasonic wasn't good enough to perform as a true color-correction bay like its higher-priced brethren.
At the 2006 DV Expo West in Los Angeles, I got my first peek at JVC's entry into this arena. I was impressed that JVC was delivering a true 1920 x 1200-pixel display as opposed to Panasonic's meager 1280 x 768. Unlike lower resolutions, which can conceal problems, 1920 x 1200 allows you to see every pixel in the HD signal.
Setup options
The DT-V24L1D comes with an adjustable stand, while its baby brother, the DTV20L1D, can be rack-mounted with an optional kit. In addition to the standard looping composite, component, and sync inputs, there are RCA audio inputs to feed the built-in speakers, and a DVI input that's handy for lower-end editing systems. The two auto-sensing SD/HD-SDI inputs have a switched SDI out for additional monitoring.
Right out of the box the monitor was nearly perfectly set up for NTSC work. Since I was working with a loaner monitor, I couldn't be sure that this would be the case with a shipping model. Nevertheless, the DT-V24L1D offers plenty of latitude and sufficient controls to adjust the image to match any standard reference situation.
Setup is aided further by the ability to monitor each of the color channels independently. In one of my favorite features, JVC has added a set of rotary knobs on the front of the monitor for adjusting the most common functions. Personally, I've grown tired of fighting through menus with a few cursor controls to tweak LCD monitors.

Performance
Once dialed in, I was amazed by the picture quality on this monitor. For the purpose of comparison, I borrowed an eCinema DCM23 monitor and placed it side by side with a Sony BVM-D 24-inch HD CRT and the DT-V24L1D. No matter how hard I tried, I couldn't get the eCinema's blacks anywhere near the JVC LCD's and the Sony CRT's richness. I found this very surprising, considering the price difference between the units.
The off-axis viewing on the DT-V24L1D also was much greater than the eCinema monitor. JVC claims a 176-degree viewing angle in all directions, which may very well be true. Of course, the CRT blew both of the LCD monitors out of the water in off-axis viewing.
Color rendition on all three monitors was very close-and barring my personal bias for CRTs, I could use any of the three to accurately color-correct a show. In reality, most consumers will be watching content on some version of flat screen technology within a few years, so getting used to a flat panel for correction now isn't such a bad idea.
When viewing a 1920 x 1080 signal on a 1920 x 1200 screen, you're left with 120 extra horizontal lines. Other manufacturers just letterbox the 1080 HD picture. JVC decided to use the extra lines to display various relevant
data. You can choose whether you want this data strip on the top or the bottom of the screen. In this area you can view your embedded audio on bar meters, embedded timecode readout, signal format, color temperature setting of the monitor, CRC errors, where sync is coming from, and which input you are looking at. Of course, you can turn the data display off if you'd rather just have black in those 120 horizontal lines.
All of my testing to this point was done in the HD world. Next, I tackled the other big challenge for LCD monitors-standard-definition video. SD is an area where CRTs always have held a clear advantage. Historically, SD scaled up to play on an HD LCD monitor has looked terrible.
The eCinema does a fair job of smoothing an SD signal out, at the cost of severe softening of the picture. I really expected the JVC to perform worse. So I was pleasantly surprised when it did a better job than the eCinema-not as good as the Sony CRT, but the best I've seen on an HD LCD so far. one problem is that up-res'd SD doesn't really fill the screen, because JVC chose not to scale all the way up to 1080.
Another feature you may find useful is the Area Marker function. Using this overlay mode, you can set up outlines for various aspect ratios and safe areas-very helpful in the new multi-format delivery world.
Conclusion
As it stands right now, the DTV24L1D is the best reference monitoring deal on the market. Compared to the other options, you get a great picture at a reasonable price. You won't have the larger installed base of color lookup tables (CLUTs) that are available for the higher-end monitors, but I think these will be available soon enough.
If I wasn't waiting to see Sony's new monitors at NAB, I would be purchasing the DT-V24L1D to replace my aging CRTs. This year's new product season promises to be an interesting one.
