As mentioned earlier there are two HDMI 2. You will have to buy the glasses separately but at least you have a choice. That's not a bad thing because we really like Firefox, it's well designed, open-sourced and easy Panasonic Viera TX-50DX750B TV use. The home screen is nice and simple with three default decks — Live TV, Apps and Devices - but you can personalise it by pinning your regularly used devices and apps to it.

You can also easily unpin them should you change your mind later. The platform also includes a search tool, allowing you to easily locate content from a variety of video services, websites and any external devices you may have connected. Panasonic Viera TX-50DX750B TV all the main video streaming services such as Netflix, Amazon and YouTube, which will provide you with additional sources of Ultra HD 4K content.


You can read a more detailed review of the Firefox Smart TV platform here. Advice like that shows a basic misunderstanding of how TV standards work and how video is actually delivered Panasonic Viera TX-50DX750B TV your display. Whilst it is true that the standards are changing, the majority of your viewing content will continue to use the Rec.


So you should have at least one setting that accurately reproduces these standards, although depending on your viewing environment, you could have two - one for daytime viewing and Panasonic Viera TX-50DX750B TV for night time viewing. The daytime setting would obviously be brighter to offset any ambient light but don't set your TV too bright in the evening or it can be fatiguing and even uncomfortable to watch. This is especially true now that modern TVs are capable of delivering greater inherent brightness because brighter doesn't necessarily mean better.

As always we setup the DX in its best out-of-the-box settings, using our night time target of nits for the overall brightness of the TV and selecting the options that are closest to the industry standards of D65 and Rec. As you can see in the graph above the DX actually delivered a fairly accurate picture out-of-the-box, although there was a deficit of red and a slight excess of green and blue. This gave whites a slight cyan push and resulted in some just noticeable errors in the brighter part of the image, although it was minor.

There Panasonic Viera TX-50DX750B TV also a slight excess of blue at 10IRE, which gave shadow details just above black a blue tinge. The gamma curve was tracking around our target of 2. The colour performance of the DX was also very good and in fact any errors were directly related to the cyan push, rather than inherent issues with the Rec.


If you look at the graph above, you can see that white is skewed toward cyan and that in turn is dragging all the other colours in that direction as well. Once we calibrate the greyscale, those errors will largely disappear. Overall Panasonic Viera TX-50DX750B TV is a decent out-of-the-box performance and with the available calibration controls it should be easy to get a reference performance in terms of greyscale and colour gamut.

Panasonic TXDXB (DX) Review

The DX was capable of delivering an accurate image, even before calibration. Picture Settings - Calibrated The DX includes an extensive and highly effective set of calibration controls that include a two- and a ten-point white balance control for adjusting the greyscale, a parametric control for fine-tuning the gamma and a Colour Management System CMS for correcting any issues with the colour gamut. We initially used the two-point white balance control to bring up red, which immediately resulted Panasonic Viera TX-50DX750B TV a near perfect greyscale performance.

We then used the ten-point to fine tune the greyscale to a reference performance with all three primary colours tracking in line with each other and the errors now all below one. The gamma was also tracking better and we could have fine tuned it further using the parametric control. After calibrating the greyscale using the white balance control, the colour temperature for white was now measuring at its target of D As result the cyan push was gone Panasonic Viera TX-50DX750B TV all the colours were measuring more accurately than before.

The new Panasonic Viera TX-50DX750B TV resolution formats are using a higher video bit-depth, a wider colour gamut based on Rec. To reflect these changes we are now measuring the out-of-the-box performance of brands against these new standards, to see what kind of performance an owner can expect from their new TV. The actual luminance begins to roll of at around 60IRE but using test patterns we could see that the Panasonic was mapping content mastered at 10,nits to the panels nits capability without clipping, which is Panasonic Viera TX-50DX750B TV. In terms of Rec.

If you turn on the Adaptive Backlight Control local dimmingthe black level immediately drops to 0. It also delivered an ANSI contrast ratio of 3, There was a little bit of dirty screen effect and occasional bright Panasonic Viera TX-50DX750B TV but overall with normal viewing material the backlight performance was very good. At night in a dark room you could see some backlight issues but those were rare and easily mitigated with some bias lighting. There were more instances of brighter edges with HDR content and black bars on letterboxed films but since the DX only has a peak brightness of nits, it isn't as apparent as on brighter TVs like the Samsung KS Local Dimming and Viewing Angles The Adaptive Backlight Control local dimming on the DX was a little disappointing, especially compared to the sophisticated system employed by Samsung, and even in the low mode we saw artefacts that were quite obvious at times.
