Sony pvm calibration

Posted: Tue Oct 16, pm. Despite the rapid advances in display technology, the perfect blacks you get from new LED and Plasma sets by now and the falling prices for giant displays, old display technology remains interesting and tempting, when it comes to retrogaming. Over the past months I've extensively tested two especially interesting candidates, which certainly represent the absolute pinnacle in picture quality for playing low-res videogames.

The BVMF1 is a 20 inch model. The BVM series features expandable inputs by adding additional input boards. Most 2nd hand displays came with a SDI board with 3 digital inputs and one additional analogue component input. The monitor itself does not contain any control elements.

Instead you use an external controller board which is connected to the monitor with a RS cable. The controller board allows full control of up to a dozen chained displays. Very fancy When shopping for a 20F1 make sure to get a control unit with it. The BVMF1 has full digital controls including full geometry and convergence controls using built-in test patterns.

The only machines I've encountered with such extensive controls were 9" CRT beamers many, many years ago. The internal storage system allows different settings on 99 "channels" and you can assign any input you like to any channel. It will accept and display p, p, i and i. A sync cleaner like the Sync Strike will help in these cases. Composite and S-Video inputs are only available through expansion boards. Some of the boards are NTSC-only, while others are multi-system-enabled. Remains the most important question of them all: how does the quality stack up?

First of all, convergence and geometry are perfect once tweaked through the internal menu system. Colors and contrast are spot-on, just the blacks can't reach the performance of today's LED and Plasma displays.

With p material you get perfectly spaced scanlines, but you'll have a very hard time to see something like a shadow mask of aperture grill. If you take a look at the close up shots below, you'll see how fine the mask actually is. When playing my head was about 70cm 2 ft from the screen and I couldn't see anything mask-related. Needless to say that the BVM is of course lag-free with all input signals. It's form perfectly flat side faces makes it easily rotateable for shoot'em ups and it's flexibility with the ability to add as many input modules as you like well, four or so make it one of it's kind.

The V was Pioneer's third and last plasma presentation display. It was made available around and was available until or Early V units still have the old Pioneer logo on front, while the later ones had the new one unfortunately just a sticker.

S-Video and composite ports are available as well. Those are downscaled to VGA then before fed into the panel. To connect a 15khz or 31khz component source, you have to add a color transcoder. For the test run I used a Burosch Con-1 converter, since it does 15khz and 31khz without the need to swap any cables. Note that no other external deinterlacers, scalers or video processors have been used with the PDP during this test run.

The PDP's controls are very rudimentary. You get a contrast and brightness control, phase and clock setting for RGB signals as well as horizontal and vertical centering controls. That's it.Page of 40 Go. Page 16 - Adjusting the Height of the Monitor wit Quick Links. Download this manual. Before operating the unit, please read this manual thoroughly. Table of Contents.

The Sony CRT is at the end of its useful life. True bit bit per each subpixel x3 panel, which means full color, and no banding or dithering. The DreamColor requires a very specific signal feeding it and he covers the why and how of it:.

The BVMs I've worked on have always been calibrated using some sort of external probe. PVMs usually have an internal Auto calibration mode, which is usually very effective but rely on the pluge in Color Bars for the user to set the brightness by eye. Sometimes, much brighter. What a great monitor. Take note of those 'Hour 1' reactions. They're very much like what I've been reading around the various forums when people move to the DreamColor from the PVMs they're thinking of replacing.

Some Basic Tips On Setting Up Sony’s PVM-1741 and PVM-2541 OLED Monitors

At the end of this article I'll be coming back to this phenomenon since I have some strong opinions on this…. CRTs are dead or dying. Production ended two years ago. Replacement tubes are hard to come by and expensive to swap out.

So given the demise of the trusted CRT, what's a colorist or anyone interested in properly displaying the visual 'creative intent' of their clients to do?

Shadow detail is where flat panels of all types and most projectors tend to fail. This flattening hides from the colorist flaws they may wish to suppress or detail they may wish to pull out. In my view, I want to replace the CRT with a flat panel that, after color grading on the panel for days on end — I can watch the CRT and not be surprised by detail I never saw.

The most important specs that any PVM- replacement must exhibit:. Is it a surprise then that an HP DreamColor, which matches all the above criteria, is on everyone's list of panels they'd love to evaluate in their room?

A last-minute job this past weekend seemed perfect for my testing. It was a 5-camera 1-hour comedy show, shot in i… Perfect! The source material had lots of dark audience shots that needed brightening, peak whites that needed managing, the codec was DVCProHD which can often have lots of compression artifacts in the shadows that I need to see and suppressand I can test the various converter boxes to see how they handle feeding an HD-SDI interlaced signal into the RGB-progressive-inputs-only DreamColor.

The panel has 6, hours of usage, which gives me a good example of how the DreamColor will respond after almost two years of regular usage.

The first step is properly calibrating the DreamColor. If I ran the DreamColor at it's full gamut, my colors would be super saturated — forcing me to heavily de-saturate the images. In HD, in SD and on the internet those resulting images would look very de-saturated and no one would ever hire me again! My first reaction was… horrific. The calibration had gone horribly wrong.

After many hours of recalibrating on both the Mac and PC and then enlisting the assistance of HP's very helpful DreamColor product team, it became clear that I had a defective colorimeter. Monday morning, after having rendering out the concert overnight, I powered up the CRT and watched the show… without the DreamColor. There were only two things left to do: Get a properly functioning probe to see if I could get an accurate calibration.

And test out NTSC footage. I'm happy to report, a properly functioning DreamColor calibration probe works wonderfully. The software is easy to use. It runs on both a Mac and PC I tested on both platforms. It also allows for calibrating to custom white points or color temperatures. Calibration does require a USB cable also hooked up between the host computer and the DreamColor this is how the final profiles are uploaded onto the LCD itself.

There is one thing I need to point out that nags at the back of my mind… the calibration only works when hooking up the DreamColor directly to the host computer off the graphics card.Some time ago I wrote a blog post on how to correctly white balance your monitor and how essential this is to a calibrated viewing environment. So how does one determine if their monitor is displaying white that is truly white? It specifies a white point at D65, degrees kelvin.

If this white point is placed correctly, it should ensure that all colors and grayscale within the gamut are accurately reproduced.

If it does not, then there are calibration issues that cannot be resolve through a white balance adjustment alone. As is exemplified in the above graphic, this is represented by a two dimensional chart with coordinates. It turns out however, these targets aren't well suited for today's OLED monitors. The BVM E and F panels are reference grade, facility-level monitors that also perform very well in the field.

The PVM's, with some calibration, are also quite accurate and for many users have proven to be adequate.

When these monitors first became available there was a lot of misinformation swirling around about how to best calibrate them. They were supposedly "perfect" right out of the box. Turns out neither of these were correct. Apparently Sony came to similar conclusions so they are now recommending the following targets for all of their OLED monitors:.

This modification is to address the persistent problem of Metamerism Failure. Flanders Scientific Instruments produced this excellent video explaining it. These Judd modified targets of x. Using the i1 Probe or one of several other spectrophotometers, Automatic White Balance software, and the Judd targets; you can get your OLED monitor reproducing an extremely neutral gray scale.

This will make anyone on the set who is referencing it confident in what they're seeing and will ensure that any color correction data made with it will be useful. Is a calibration using the i1 probe as accurate as one done with a facility level colorimeter? These can be made in Final Cut Pro easily. If they are not in equilibrium, there is chroma contamination in the video.

Abel Cine has a great primer on how to do this process automatically but it can also be done manually, with the following steps. With the calibration cap solid, light-tight black cap firmly on the probe, select the X-Rite i1 from the probe choices in the software.

Hit it and your probe is now calibrated and ready to read. Remove the cap and put the probe in the cradle that allows it to hang flush on the surface of the monitor.

Leaning the monitor slightly back will help gravity hold the probe in place. All of these variables are intrinsically related so affecting one will likely affect the other. Hitting all targets requires a good deal of back and forth adjustment. Using RGB Gains, you will now affect the x and y point.Page of 37 Go.

Cancel Delete.The PVM X is definitely not your average monitor. This model is a genuine issue 4K UHD broadcast display and comes with the specialized specs to make the process work in virtually any studio setting. Thus, for cinema-grade 4K production the X is definitely built to deliver, in terms of onset monitoring and for editing needs as they come along.

On top of all these things the PVM-X is built to be maximally portable, easy to install in any studio setting and offers a broad list of connectivity ports for professional studio needs. The SmartView 4K from Blackmagic being a good example of this great connectivity, only moderately good display qualities.

Thus, with the PVM you get your hands on a very nicely sized true 4K display that delivers the same X pixels which are used in many professional cinema cameras and thus lets you fit the whole video resolution of high-end 4K shooting footage into the screen without resizing. Furthermore, that true 4K resolution is shown on a good-sized 30 inch screen that offers plenty of working room and visibility.

Furthermore, the color specs of the PVM X are nothing to laugh at. Finally, what really puts a cherry on top for the PVM X is the simple fact that this is a very versatile and mobile monitor despite its large screen sized. Built with a hardy design and with easy transportation in mind, the X can quickly be moved to any studio or mobile set shooting environment and set up in no time. There is little that can be called bad about the PVM-X This is a performance piece of hardware and one of the finer 4K broadcast monitors on the market today.

We can say however that ultra HD broadcast monitors are still a very new technology and even better models among the very few generally available on sale are still in their earlier implementations and thus might not be quite as good or as affordable as models slightly down the road will be.

By it is virtually certain that 4K UHD will be the widely accepted broadcast standard worldwide and 4K workflow displays will be as common and well developed as their HD counterparts still are right now.

Thus, you can view the PVM-X as an early iteration of a de facto future technology. And like almost all early models, it is genuinely very expensive, even by its own professional standards and some of the specs it features will almost certainly modernize further with newer models in the next couple years.

As we explained above, the PVM-X offers a very robust package of broadcasting and workflow technology in 4K. However, it is not as good a piece of technology as 4K broadcast monitors will become within the next year or two and thus, if you want to save a lot of money while still getting the benefits of 4K broadcast monitoring technology, you might choose the somewhat inferior and much smaller but still highly versatile Blackmagic SmartView 4K. Weight: The highlights of the PVM-X start with the visuals it offers.

While all broadcast monitors need to come with a decent display quality, not all of them go out of their necessary way to deliver something with decent quality. In this regar the PVM-X stands out. Couple this with the true 4K display resolution and the X is quite golden. Its broad range of connectivity specs and its extremely flexible input make use under varied conditions practical. You could definitely find an even light broadcast monitor in the form of the Blackmagic SmartView 4K but the X offers a solid mix of both worlds: the ideal size for really effective monitoring of visuals but portability at the same time.

On the other hand, for other types of video, the monitor is more than capable of handling multiple 4K formats. All of these can be managed from just a single HMDI cable. The monitor can also handle HD display modes of x and of course x These other machines offer a much broader and more flexible range of visual specs for editing and post-production of 4K video.

Finally, it offers triple DisplayPort connectivity for 4K at 60 frames per second. This includes a single DisplayPort 1. This would have been a very useful feature, particularly in mobile sets.

This is another feature which would have really made the X even more outstanding. To quickly summarize the less than ideal features of the PVM-X This monitor is hig up on the price scale and in exchange for that it offers connectivity that isn't quite as good as that offered by certain other more affordable broadcast monitors, particularly the Blackmagic Smartview 4K, which costs several time less than the X Thus, much of the price here seems to cover the PVM's size including display size and its display features for onset monitoring.

However, neither of these are absolutely spectacular, although they're definitely of professional caliber. The PVM-X offers a fantastic package as a 4K broadcast monitor, but if you're looking to do onset monitoring and studio broadcast work professionally but on a budget, cheaper alternatives of excellent quality exist.

Manufacture Sony. Specs Weight: Not so Great To quickly summarize the less than ideal features of the PVM-X This monitor is hig up on the price scale and in exchange for that it offers connectivity that isn't quite as good as that offered by certain other more affordable broadcast monitors, particularly the Blackmagic Smartview 4K, which costs several time less than the XIt's simple.

It's fast. But it does require a professional display to be fully successful.

In Part 6 of this series we performed a series of pre-calibration steps. That step ensured our digital image pipeline is accurate. Here in Part 7 we move to the actual calibration, ensuring our display is accurate. And we do it without using LUTs. Generally speaking, the type of calibration we perform a 2-Point Grayscale Calibration is super simple. We are merely calibrating the white point of the display using two test patches: Pure white or near pure white and near pure black.

IF your display tracks accurately then adjusting those two patches will bring your display into alignment. In this workflow it is essential that you run the CalMAN series of post-calibration test patches. These will give you the feedback you need to understand if this 2-point calibration is sufficient for your display.

Calibrating Sony PVM-A250

The first time we calibrate we use the Rec. As a colorist, the A is too small for my daily needs. But if I practiced my craft on-set — and needed a reference display on a small mobile DIT cart, this display is certainly up to that task.

This particular display is a good example of calibrating a display a year into its life. If, instead, it had been seeing duty hours per year then we can expect it to suffer from the same aging problems of all displays.
