Pioneer Elite PRO-950HD Plasma Calibration

Pioneer Elite PRO-950HD Plasma Calibration
I have calibrated several Pioneer Elite plasmas of late but I wanted to write about this one because it’s the first 720p model I’ve worked with. Besides resolution, the spec sheet reads identical to the 1080p models, the PRO-110 and 150. It employs the same screen filter and coating which contribute to its outstanding black-level performance. It also includes the same menu structure and high-quality video processing of its higher-resolution brethren. At 42 inches, this TV is perfect for smaller rooms. It has plenty of light output so it can be enjoyed in a wide variety of lighting conditions.

The calibration procedure was identical to the PRO-150FD (click here for my article) so I won’t reiterate it here. My main purpose with this article is to talk about the superb performance numbers I achieved. While other calibrators have stated they couldn’t measure black levels on these panels, I had not encountered this phenomenon. I could always measure at least .001 fl. This panel however would not register a black level reading. Even after raising brightness from the default (Pluge patterns did not show below-black until this was done), I could not measure the black level on any pattern. I check these numbers with a full-field 0 IRE and an ANSI contrast checkerboard. No part of the screen registered a reading. My instruments therefore returned an infinite on/off and ANSI contrast ratio! Gamma was still a solid 2.2. I viewed the Pluge patterns in low to mid-level room light. Patterns were generated by an Accupel HDG-3000.

Performance in other areas was identical to the 1080p models. Color primaries were slightly oversaturated and decoding was error-free. Edge enhancement was easily defeated by reducing the sharpness control. I did encounter one interesting thing that I had not dealt with before. My client occasionally connects a computer to one of the TVs HDMI inputs to view photos. When connecting this way, there is no control over pixel clock or phase. The result is the TV displays a different portion of the computer’s desktop. To view the slideshow, my client has to drag the pictures off the top of the computer’s screen so they are visible on the TV. I can only speculate that this is a product of HDCP. The only workaround is to use the VGA port on the TV. This allows adjustment so you can sync the computer and the TV. It depends on what outputs are available on your computer.

In summary, I was most impressed with this TV. At a 42-inch screen size, 720p was a more than sufficient resolution for high-quality imaging. DVDs and high-def cable looked excellent as did the photos from a computer. At an MSRP of $2700, I consider this an excellent value in plasma TVs. Given that the cheapest 1080p model (the 50-inch PRO-110FD) has an MSRP of $6000, you’re only giving up a little screen size for a huge savings.

Panasonic TH-42PH9UK Pro Plasma Calibration

The plasma market is dominated by just 2 manufacturers, Panasonic and Pioneer. I have already covered the Kuro 5010FD and the Panasonic PZ700U. The third TV vying for alpha status in this hot segment is the professional line of Panasonic plasmas. There are 720p and 1080p models ranging from 37 to 103 inches. Today’s subject is the 42-inch, 720p PH9UK.

The pro-Panasonic models are strictly monitors. There is no internal tuner or speakers. You can buy add-on speakers which bolt to the sides of the panel for about $600. You’ll also need to add a pedestal stand or a wall-mount bracket. Inputs are customizable with 3 slots for “blades” or terminal boards. You can have different combinations of HDMI and analog inputs to suit your particular system. The newest models, the PF10 series, come with a dual HDMI board that accepts 24p signals. This particular PH9 had a single HDMI input and a component input, both of which I calibrated.

Each input has its own memory for all settings which is very nice. There are a complete set of controls in the user menu for grayscale and gamma. In addition you can adjust image size and position for each scan rate independently. Upon setting up my pattern generator, the first thing I noticed was the extremely stable black levels. There was no visible change in the pluge patterns as I moved through different APL patterns. The DC restoration was every bit the equal of a Pioneer Kuro. Color primaries were slightly oversaturated but the decoding was spot on at factory defaults. Rec 709 colorspace was used for all scan rates. Grayscale was fair at the warm color temp setting. Once the white balance controls were adjusted, tracking was within 100k of D65 from 20-100 IRE. There are only red and blue controls for high and low but they were sufficient to achieve a nearly perfect grayscale. The newer models have a full set of RGB cuts and gains. There is a gamma control which has 4 settings. Default is 2.2 but to actually achieve a 2.2 gamma, I had to set it on 2.4. The gamma curve was absolutely perfect at all scan rates on both component and HDMI. I was able to set contrast fairly high without any color shift. This gave me a bright, punchy image upon completion of my work.

The end result was a reference-quality image for both HD and SD. These panels are used professionally as mastering monitors for a good reason. The video processing on this panel is excellent. It did quite well with the motion tests on Avia Pro. Upconversion of SD material was very good. Since this panel is actually 1366x768, all material is scaled including 720p content. It will accept 1080i signals. I can’t help but recommend this and all pro-Panasonic panels as the value leader. A 50-inch PF10UK can be had for under $2500, accepts 1080p/24 and is a rugged, well-built TV. The 720p panels are even cheaper with the 50-inch coming in at under $1500. You can’t go wrong with any panel from either Panasonic or Pioneer. But you’re looking for the most display for the money and you don’t need speakers or a tuner, the pro-Panasonics can’t be beat.

Pioneer Plasma 5010FD Calibration

Much has been written in praise of the current line of Pioneer plasmas called Kuro. These TVs are reputed to have contrast ratios and black levels comparable to CRTs. I can say after spending some quality time with a 5010FD that this reputation is well-earned. The 5010 is part of a line that includes 42 and 50-inch 720p panels and 50 and 60-inch 1080p panels. Each variant is available as an Elite model as well. The 5010 is the 50-inch 1080p, non-Elite version. The glass and video processing is the same across all the 1080p sets. The Elite TVs add more adjustments and more precise setup at the factory. They also have a different screen coating to improve contrast and ambient light rejection. They also add $1000 to the retail price!

My subject today is the calibration of a 5010FD. Sources were a satellite tuner and a Denon DVD player, both connected via HDMI. The client had made no adjustments prior to my visit so I was starting with an out-of-the-box TV. There are the usual picture modes but only Movie and User allow access to all adjustments. These are in a sub-menu called Pro Adjust. I started in Movie mode. All enhancements were turned off. I immediately found a lot of interaction between Brightness, Contrast and the 3 Gamma settings. I also discovered differences in grayscale and gamma between Movie and User modes. Staying with User mode, I optimized Brightness and Contrast and achieved the best Gamma with setting 1. After adjusting Color and Tint with my CA6X analyzer, I found the grayscale to be within a whisker of D65 without having adjusted any Gains or Cuts. These controls are available in service but they just weren't necessary in this case. I really took my time to maximize the overall contrast ratio. In the end, I achieved a perfect gamma of 2.2, a grayscale within 150k of D65 and an ANSI contrast ratio of 448:1. Some of the black squares in the pattern read below .005 foot-lamberts, the lower limit of my meter! 100 IRE measured 21.97 fL with a full field and 49.5 fL with a window. This is the highest contrast I've ever measured. This was with a fully-resolved Pluge pattern and nearly perfect color accuracy.

Moving on to the DVD player, I noticed a change in gamma when I copied my new settings to its input. I tried changing to the Movie mode and things greatly improved. Gamma was back at 2.2 and the grayscale was again within 150k of D65. The player was a Denon 1940, an excellent player in the $350 range. A few tweaks to the other controls to dial in the player and my job was done.

All in all, this was a very pleasurable calibration. This TV is extremely well-made and color accuracy is obviously a priority for Pioneer. I still believe it benefits from professional calibration (of course!). There are interactions between most of the controls and without the benefit of instruments and experience, it's easy to become lost. This is truly a high-end video display. Why not set it up for maximum performance? One side note: this is one of the few displays on the market that supports 24p input, displaying the signal at 72 Hz. This makes it a perfect display for hi-def disc players that output 1080p/24. A new Blu-ray player is the perfect match for this excellent TV. Pioneer has really raised the bar with the Kuro line.

Panasonic TH-37PX60U Plasma Calibration

Another Panasonic so soon! I guess calibrations go in phases. For awhile it was Sonys. This plasma panel is a bit older than the 700U I wrote about recently. My client has had it about a year and he was ready to unlock its full potential. This 37" TV is a nice size for those of you who have an entertainment center or AV cabinet. It fits comfortably in or on many different types of furniture. If you want a TV that doesn't draw attention to itself, this panel is an excellent choice.

Since this is a 720p (1024x768 native) display, I set my pattern generator for this resolution. I also set the cable box and upconverting DVD player in the client's system for these resolutions. It is always best to feed a display its native format whenever possible to minimize any video processing done by the set. Color primaries measured a bit oversaturated for green and red and near-perfect for blue, typical of Panasonic plasmas. Interestingly, this client had the color temp set to a warmer than D65 level. Most people are accustomed to a bluish tint on their TVs and set the color temp to normal or even cool. This is the first client I've had who actually had become accustomed to a too-warm white balance. I also noticed a fair amount of noise in the various test patterns I displayed. Unlike the 700U, the sharpness control did not help this condition.

After doing rough settings in the user menu, I entered service to adjust white balance, and black/white levels. This was tricky at first as going into service sets the TV to Vivid mode. I was fortunately able to toggle between user and service to force the TV into Cinema mode. Cinema is the only mode that allows different settings for each input. The other modes have global settings. Once I set the Cinema mode, white balance was easily adjusted to within 100k of D65. Setting black level in service also allowed me a much finer adjustment than the user menu. Exiting service, I immediately noticed a huge reduction in noise. The multi-burst patterns were now very clean and sharp. Obviously, color adjustments on this set have quite an effect on overall noise levels. As with the 700U, the noise reduction controls in user had no visible effect. The only other adjustment required was to reduce the color and tint controls a bit to compensate for the oversaturated green and red primaries. My trusty CA-6X analyzer came through once again to help me align the decoder more accurately than I could using filters. To my knowledge, no other colorimeter has this feature. It allows me to adjust the color and tint controls to align the decoder to the measured primaries rather than the reference. This is far more precise than filters which only work if the primaries are correct and you're calibrating a CRT.

As usual, my client and I checked out some content when I was finished. Discovery HD over a Cablevision feed looked stunning (I really love plasmas for HD!). The color resolution was so much better than before. My client commented that he could really see an increased color palette. There's nothing like lifting the veil of image inaccuracy and seeing what the content creator intended rather than what the television's manufacturer intended. Raiders of the Lost Ark from a Sony upconverting DVD player looked great too. This THX-certified transfer is an excellent reference for any player or display. The clarity of this DVD release is matched by few other titles. Now that we're on the eve of having all our movies in hi-def, it's still gratifying to see standard-def DVD done so well.

Just like the 700U I reported on recently, this TV is a top candidate for calibration. The client and I were very happy with the results. He considered it well worth the price and I considered it well worth my time. A properly calibrated plasma is probably the closest we can get to the venerable CRT in terms of dynamic range, contrast ratio and color saturation. I do suggest viewing plasmas in a light-controlled room. Reflections from lights and windows can be seen on the glass screen. The image is plenty bright enough however, to compete with indirect light sources. As my client had his panel in a cabinet, he solved the problem of light reflection quite nicely.

Another happy customer, thanks for reading!

Panasonic TH50-PZ700U Calibration

I had an opportunity this past week to calibrate this latest Panasonic plasma. The PZ700U is 1080p with 2 HDMI inputs and a slot for an SD memory card to display photos. This display is not only one of the best plasma panels available today, it is also by far the best value. The only brand at this level is the Pioneer Elite line and you'll pay more than double the price for the same screen size.

There are 4 picture modes available, Standard, Vivid, Cinema and Custom. Only the Custom setting allows different settings per input. Selecting the Warm color temp got me within striking distance of D65. One interesting thing I learned concerned video noise reduction. There are 3 controls that address noise reduction and none of them seemed to affect the image at all. I was viewing 1080i multi-burst patterns and even though the 1-pixel pattern was rendered perfectly, I could see just a bit of noise around it. I finally removed the noise by turning up the Sharpness a few clicks from off. In fact, the Sharpness control at full blast didn't introduce any ringing in the image. My conclusion is that Sharpness on this TV affects noise and not edge enhancement. Another factor is the HDSize control. There are 2 options. Number 2 combined with Normal Aspect will give a 1:1 pixel map. The first option introduces about 3% overscan which is in spec but it breaks up the 1 pixel multi-burst. Bottom line, the sharpest and cleanest image comes in the 1:1 pixel mode.

Grayscale tracking showed a Delta C* error of 5-13 before calibration and under 1 after adjustments were made in service. I was also able to improve gamma and black levels by working the sub-brightness adjustment. I noticed when adjusting Brightness in the user menu that there would be a certain point where the gamma curve would change visibly on one side or the other of a particular number. Just below this point was the sweet spot for the final Brightness setting. After exiting service, I loaded a few Blu-Ray titles into the client's PS3 for some real content analysis. The first thing we noticed is there was still some downward room to be had in black levels. I settled on another 3 clicks lower on both the PS3 and the SA8300HD cable box sources. Like the majority of consumer displays, the black levels float somewhat depending on the average light level of the image. The adjustments made in service greatly reduced this tendency. For example; before calibration the darkest Pluge pattern would actually change after a few seconds. The lighter bar would at first be visible then disappear. After calibration, the pattern remained stable. The change in different light output levels also had less of an effect on black level. Even though this set is decent before calibration, this improvement alone is worth doing a full calibration.

The color-related aspects of the picture were excellent all around. Primaries are dead on for blue and slightly over-saturated for red and green. This is not visible in content. A slight lowering of the Color control aligned the decoder fairly well. Using my Progressive Labs CA6X allowed me to adjust the Tint to correct secondary color errors with respect to the measured primaries. This is much more accurate than using filters. Filters are only useful if they match the displays actual primaries and this is quite rare.

In conclusion, I would rate this as one of the finest HDTVs I have calibrated to date. It's the closest in dynamic range and clarity to the legendary Sony XBR960 CRT, my benchmark. Given the amazing price point of this TV (around $2500), there is no better value to be had, period. There is certainly no 50-inch LCD of any decent quality that sells for as little. And I have yet to encounter an LCD that can reproduce the blacks this TV can. I was so impressed with this display that I'll be adding one to my own theater in the coming months.
