Review: Vizio 65-inch 4K Ultra HDTV (P652ui-B2), a low-cost 4K solution



This is going to be a busy year when it comes to talking about 4K, as manufacturers continue to push the new TVs into becoming the new living room standard. One of the most popular brands here on the Tech Blog is Vizio as they have been doing their part in making it easier to obtain such an upgrade at more of an affordable price point. This time, we get to take a look at their 65-inch member of the P-Series, the P652ui-B2 4K Ultra HDTV.

There isn’t really much difference compared to the current 1080 models in design. Both frame and stand are similar. The TV itself is about 2.3 inches in depth making it a thicker than some of the other options, so although it will mount just fine on the wall, it looks better on the stand. The screen has a matte finish to it, reducing reflection which is nice, allowing it to look nice both in dark environments as well as sunny.

The TV is LED back-lit and local dimming with 64 active zones for dark blacks and solid detail. The refresh rate is only 120hz but offers 240hz effective—so lovers of the soap opera effect won’t be let down (of course this can be disabled in the menus as usual by turning off Smooth Motion Effect).

We used our typical calibration discs as always, but the Vizio also has its own in the menus which is nice as it really gets you ahead without the need of any external media. You can even save your custom settings to the presets and name it whatever you like. Initially, the picture was off balance and needed a decent amount of tweaking. Once everything was dialed in, the picture looked pretty nice though outside of a few variables.

Watching various scenes from a handful of Blu-ray movies, we found the picture to be pretty solid. The only thing we could complain about was there was a little too much red in certain situations such as skin tones. Beyond that, everything looked great. Both live action scenes and animations led to rich colors and strong detail. Blacks were strong as well.

Streaming media however didn’t always deliver. The app selection on the TV is the same as it has been on other Vizio models with all of the typical options to choose from and we didn’t experience any kind of lag during playback. It supports both WiFi and ethernet for connectivity. At times though, the picture seemed to get a little messy. We don’t know if that was the image processing or if it was a bug that Netflix was experiencing. It wasn’t a consistent issue, but enough of one to know that it would become annoying after some time. The one thing we didn’t do though, was check for a firmware upgrade before going through our initial tests (whoops). Sure enough, one was available and after upgrading, the messiness was noticeably reduced. Vizio apparently may also be working on another firmware update soon, so that is something to look for.

Another quality to note is that after the firmware update, the TV looked a lot better at factory settings (out of the box). It appears they touched on some of the factory settings so that users don’t have to work so hard to calibrate it to a better looking image.

The P652ui-B2 offers support for the new HEVC H.265 compression format, which allows it to support full 4K@60 streaming via sources like Netflix and YouTube as well as media playback of files via the USB input. The new format allows 4K to be streamed at a compressed rate that current connections are capable of handling while providing a mostly lossless experience.

Throwing on a few Xbox One games to test out, the TV delivered wonderful graphics. We had to enable Gaming Mode to help reduce input-lag, but that’s common for all LED TVs, and it accomplished just what it was supposed to. We didn’t experience any noticeable lag while playing online. In fact, it felt like one of the most natural LED TVs we have ever attempted to play a first-person shooter on.

There are a total of 5 HDMI inputs to choose from, but only one of them supports HDMI 2.0 (capable of 4K@60) with HDCP 2.2, where the other 4 are HDMI 1.4 and can only pass 4K@30 (two of which also support HDCP 2.2). There is an optical out for connecting to a soundbar or receiver with 5.1 digital sound as well as an RCA analog. You will also find composite and component inputs, one coax and one USB.

Once again, this is another TV that does not support 3D, so we were unable to perform any testing in this area. Of course, we are notorious for pointing out the failures of today’s “3D” technology any how, so there isn’t really any loss there. Maybe eventually we will have the option of using Microsoft’s upcoming HoloLens (or a similar product) to bring a better world of 3D to TVs in our living rooms. Until then, 3D just isn’t quite there yet. However, if you are a dire fan of today’s 3D, then your hunger will not be tamed with this model.

xrt500_20Before leading to the conclusion, let’s take a look at the remote! We love remotes that feature a full qwerty keyboard on the back, and this one offers just that. The front side of the remote has all of your typical buttons while the keyboard rocks its bad self on the back. The keyboard also lights up making it easier to find the smaller buttons in low light situations. There were no noticeable problems with the remote in terms of having to aim directly at a portion of the TV or anything. There is nothing like a remote that works and cuts out the need of having to buy a wireless keyboard to take up space on your coffee table with.

Our Conclusion

The P652ui-B2 is a formidable 4K solution at a low price. At a price of $1799 or higher (at the time of this review), it performs pretty well and we expect that the price will only fall a little more as we reach towards the end of the year. Prices for 4K are coming down all over, but this model mixes within the range of the 50-inch options of other brands, giving a much larger prize. We decided to give it a 7.5 out of 10 due to the fact that the firmware update covered most of our concerns. Another update would probably being it closer to 8 or 8.5 depending on how well it cleans up the 4K image a little on streaming.

    If you’re planning on using the P as a gaming monitor with an Nvidia 900 series card, you may not get 4k60hz despite both being HDMI 2.0. P-55 and EVGA 970 do NOT get 60hz with 4k.. P-series do NOT support 4:4:4 chroma, and the 900 cards do not support 4:2:2 over the HDMI connection.
