Vizio PX75-G1 P-Series Quantum X LCD Ultra HDTV Review Settings


Unit-to-unit sample variations, the viewing environment, and the source might render these recommendations less than optimum. They are only provided as a potentially useful starting place. Note that the usefulness of the Color Tuner settings provided here may not produce the best possible result on another sample.

For settings such as Backlight, Brightness, and Çontrast, we strongly recommend that you find the optimum basic video settings for your sample by using one of the many available HD/SDR setup discs, such as the Disney "WOW" or the Spears and Munsil High Definition Benchmark (a Spears and Munsil disc for Ultra HD/HDR has just been released as of this writing)). These will help you set the basic controls correctly, though are not designed for color calibration. Experimenting with the color calibration controls in the user menus will do no harm; the changes may be easily reset. But adjusting these by eye is unlikely to produce an accurate result and is no substitute for a full color calibration. The latter is best left to a trained and properly equipped technician such as those certified by the Imaging Science Foundation (ISF) or THX. Some minor subsequent adjustments to the non-Color Tuner controls may produce the best visual results on specific source material. Those alterations in our situation are reflected in the settings shown below.

I have a 65" vizio M series from 2018 and I love everything about the TV except the stupid menus.

It's mind-boggling that menus on my 386 computer from 1989 are snappier than menus on my 2018 smart TV.

Thanks Tom for review. I'm waiting on the new soon to be released Quantum X at 85" screen size. Vizio is supposed to have improved it's processing chip and interface. If the reviews bare out the improvements, and its price at $3,000 or less then it would be the deal of the year for a premium 4k.

I purchased and mounted this TV in December and I'm mystified by some odd discrepancies in the review. Strangely, the picture of the remote is entirely different from the remote that I have! My remote is surprisingly heavy, with it's main body made of satin-finished aluminum that matches the aluminum trim on the TV. The remote's keypad has a seamless black rubber surface with raised buttons. It's very attractive with a solid luxurious feel to it with a really clever spring loaded drawer for its batteries that pushes in and then springs out from the slender bottom of the remote.
The other thing about my set that seems at odds with the reviewer's experience is the responsiveness of the set's user interface. My set is hard-wired to the house's gigabit ethernet network and the interface responds smoothly and quickly to the remote's input, in my limited experience. I have not tried Vizio's app control, yet. Accessing Hulu, Netflix and Amazon Prime is nearly instantaneous and definitely comparable to my FireCube and Roku Ultra boxes.
And the picture? With some of the better 4K HDR content, the picture is eerily three dimensional as if the image we're seeing is really on the other side of the world's cleanest pane of glass.
But I have to admit, playing Mariokart on the Nintendo Switch console on this TV has made me nauseous from motion sickness more than a few times. Now how many TVs can do that?? Most importantly for me, rapidly panning images on this TV do not lose resolution and pixellate, which has been the primary reason preventing me from giving up my Kuro plasma panel. And surprisingly, the Vizio's black level performance is superb. Must be from all those hundreds of local dimming zones.
Thanks for the great review of a great TV! I hope lotsa people buy and enjoy this outstanding TV as much as I have.

I wish to make clear that the discrepancies I reported are in no way the fault of the reviewer. Ten to one, it's all attributable to the Chinese manufacturer making incremental changes within the manufacturing cycle of a product. It happens quite often, actually.

Overall, it appears to offer a compelling value proposition in the 75-inch Ultra HDTV category.

Its ability to handle various HDR formats without the need for tone mapping is a noteworthy feature, especially considering its affordable price. - move closet

The Vizio's optical digital output can pass lossy multichannel soundtracks in bitstream format to an external AVR or soundbar.
