VIZIO P502ui-B1 Review – Introduced in late 2014, the VIZIO P-Series 4K Ultra HD Full-Array LED Smart TV has great features at a jaw-dropping price - the 50 inch is currently selling at Amazon for just Check Latest Price

But many people steer clear of 4K because of the initial high cost of these sets. Now that Vizio have entered the market with their P-series range of televisions from 50" up to 70", the choice to go 4K is becoming attainable for more and more consumers.

One thing you should be aware of is that this TV does not have 3D built in - so if 3D is an important feature on your shopping list, then, as an alternative take a look at the LG Electronics 49UB8500

VIZIO P502ui-B1 - Design

The design of the Vizio P502ui-B1 is quite basic with a dark silver coloured finish around the screen edge and a thin black bezel around the screen. The corners are very slightly rounded and the base is open and fixed - i.e. there is no swivel in the stand.  

This 50" entry model comes with a table stand or can be wall mounted - whichever suits you best. It has minimalist styling that is discrete and contemporary to look good in any room.  But the central stand has the great advantage that it is not the full width of the TV which means that it will sit quite comfortably on many existing TV units- although you need to make sure that the positioning precludes being knocked from the side (tip: some small blobs of blu-tack or similar, strategically placed under the TV stand can help it to grip the unit and avoid movement from minor knocks).

Vizio have focussed all their efforts and costs on the performance of the P series, leaving the design basic but clean. There is nothing objectionable but nothing outstanding either. In practice, when you are immersed in TV, the design is not the most important factor - especially if you choose to wall mount as many will with this 50 inch flat panel TV.

VIZIO P502ui-B1 - Connections

Vizio have prioritised good connectivity and there is a great range of inputs including 5 HDMI, 2 on the side and 3 on the rear, downward facing.  Of these, 4 are specified 4K @ 30 Hz and 2 of these have HDCP 2.2 support.  The fifth, side HDMI input is 4K @ 60 Hz or 1080P @120Hz with HDCP 2.2 support.

Since HDCP 2.2 is the likely standard for copyright protection between 4K devices, Vizio have provided good support for future devices such as 4K blu-ray.

In addition to the HDMI slots, there is one USB port for photo, music and video (DNLA compliant), analog audio and optical digital outputs plus legacy component video and composite video.

Internet can be connected via built-in wifi which is fast 802.11ac or by ethernet cable.  Personally I prefer to hard wire for streaming as it is less prone to interference - particularly around a lot of electrical equipment.

VIZIO P502ui-B1 - Picture

Vizio has produced a 4K Ultra HD TV sub $1,000 that can future proof your next TV purchase. Although 4K isn't standard yet, it is clear that TV manufacturers are adopting this resolution as the next standard. Just as HD eclipsed the old standard definition, 4K is set to oust HD. 

Vizio's P-series of 4K televisions are exceptional in the market insofar as, with the exception on the 55" model, they have LCD VA panels with full-array LED backlight and 64 Active LED Zones. The benefit of this is much better contrast and deeper black levels to give great picture quality in a 4K TV in this price range where competitor tv displays are only edge-lit LED.

The display finish is semi-matte so this means that you will get less reflection on the screen than with a more glossy screen.

Vizio have made the picture quality paramount in their design of this 4K TV. Upscaling is handled by advanced graphic processing so that you can enjoy your HD programmes in simulated 4K resolution.

One feature that is not included is 3D - as previously mentioned, if this is important to you then this TV will probably not be the right choice.

VIZIO P502ui-B1 - Sound

The sound from the P-series is fairly mediocre with just two 10W speakers.   So you will probably want to add a soundbase or a sound bar if you do not plan to wire the sound through an AV Receiver setup.

Perhaps the most noticeable difference between this Vizio P series of 4K LED televisions and other brands is that it has Full-Array LED backlight with 64 Active LED Zones. The set dynamically adjusts the LED backlight in each individual zone creating deeper, pure black levels and higher contrast – a feature unmatched by other brands at this price level.
