My Initial Thoughts

VIZIO D65x-G4 Review: My Initial Thoughts

VIZIO is one of the most prominent 4K TV manufacturers, known for producing high-quality, budget-friendly televisions. Furthermore, in 2016, this TV brand introduced its D-Series with about 25 unique models which had excellent features and different sizes to choose from.

A model in this D-Series is the VIZIO D65x-G4. This television is a 4K TV that comes with great features, including an impressive contract ratio, low input lag, and an in-built Chromecast.

However, this TV lacks some important features that could turn off potential buyers. What are these features that I am talking about?

Read on to find out!

D65x-G4 Design, Dimension, and Weight Review

For a TV that won’t break the bank, the VIZIO D65x-G4 sure has a decent design. To give more details, this television features a plastic chassis with a smooth matte-black finish.

Additionally, the TV has not-too-thick, not-too-slim plastic bezels that surround its display screen. Also, these bezels feature the same matte-black finish as the chassis of the television.

As expected, there is a “VIZIO” logo neatly placed at the center of the bottom bezels. This logo gives the television a rather appealing look when viewed from the front.

That said, the VIZIO D65x-G4 comes with a pair of “V” shaped legs. Although these legs are also made of plastic, they are very sturdy and support the TV very well.

However, the legs are widely spread across the edges of the television. Thus, if not wall-mounted, you will need a fairly large desk or surface to place the VIZIO D65x-G4.

Turning the VIZIO D65x-G4 over to the back, you will discover a matte-black plastic panel. The ports for this television are distributed on this plastic panel.

To give more details, some ports are side-facing on the TV’s back, while some are down-facing. However, there is no space provided for cable management on the back of the television.

Also, the back of the TV is somewhat thick. As a result, the TV will look kind of awkward if mounted on the wall.

On a positive note, unlike most 65-inch TV, the VIZIO D65x-G4 isn’t particularly heavy. In fact, one person can carry and assemble the TV.

To give more details, this TV weighs 17400 g and measures 1457.2 x 73.4 x 833.1 mm. When compared with the Samsung UN65RU7100FXZA, the VIZIO D65x-G4 weighs less.

Specifically, the Samsung UN65RU7100FXZA weighs a massive 24992 g and measures 1457 x 58.4 x 838 mm.

In conclusion, the VIZIO D65x-G4 features a decent design for an affordable 4K TV. Also, despite featuring a thick back panel, this TV weighs less than most competing TVs.

Therefore, it is ideal to rate the VIZIO D65x-G4 an eight out of ten in this design review section.

D65x-G4 Display Features Review

VIZIO D65x-G4 Display Features Review

For the display, the VIZIO D65x-G4 comes with a 65-inch LED display. As expected, this display features a 4K UHD (3840 x 2160) resolution.

In modern-day televisions, 4K resolutions are becoming increasingly popular.
This is because 4K resolution allows displays to deliver colorful and accurate picture quality. 

Besides, a 4K resolution display like the VIZIO D65x-G4’s display is about 4x better, sharper, and more colorful than a typical HD resolution display.

Impressively, the VIZIO D65x-G4’s 65-inch display comes with an impressive contrast ratio. To be more specific, the display features a contrast ratio of 5,392:1.

You must be probably wondering what contrast ratio is. Let me briefly explain.

The contrast ratio of a display is the difference between the highest and lowest luminance of the display. Basically, it is the ratio between the brightest white and the darkest black that the display can produce.

In addition to that, a high contrast ratio means the display can produce deep black. Thankfully, since the VIZIO D65x-G4’s display features a high contrast ratio – so, it should be able to produce deep blacks.

Therefore, movies with a significant number of dark scenes will be a joy to watch on the VIZIO D65x-G4.

However, despite its impressive contrast ratio, this television’s display doesn’t support local dimming. For clarity, Local dimming is a technique that LED/LCD displays use to improve their contrast ratio by dimming backlight zones.

This technique makes blacks appear deeper than they normally are. Thus, improving the overall picture quality of the display.

On a positive note, the VIZIO D65x-G4’s display supports HDR (High Dynamic Range). To be more specific, this display supports several HDR formats, including HDR10 and HLG (Hybrid Log-Gamma).

Let me quickly define HDR in a few words. When viewing HDR-supported content, HDR is a picture technology that allows a display to enhance picture quality and contrast.

Moreover, HDR-supported content is mostly found on streaming apps like Netflix, Disney+, and HULU.

However, despite supporting HDR, the VIZIO D65x-G4’s display has poor brightness. To be more specific, this display has a maximum brightness of just 211 nits.

As a result, the VIZIO D65x-G4 isn’t ideal for use in well-lit areas. You are better off viewing the TV in a moderately lit or dim room.

On a bright note, the VIZIO D65x-G4’s display features a semi-gloss coating that protects it from reflections. However, this semi-gloss coating can only prevent reflections effectively in moderately-lit rooms.

Thus, when using this TV in a well-lit room or under direct sunlight, reflections might cause a big problem.

Moving on, the VIZIO D65x-G4’s display comes with very poor viewing angles. Therefore, color accuracy and picture quality will reduce when viewing the television from the sides.

Speaking of color accuracy, when viewed directly from the center, the VIZIO D65x-G4’s display produces some pretty accurate colors. To top that up, this television’s display comes with an impressive response time of 12.1 milliseconds.

Therefore, fast-motion content like sports will be pleasant to watch on the VIZIO D65x-G4. Lest I forget, response time is the amount of time it takes a display to fully transition from one color to another.

To add icing to the cake, the VIZIO D65x-G4’s display also has a low input lag of 23.9 ms. Input lag is the time taken for a device’s display to respond to signal inputs.

Additionally, the lower the input lag a display has, the better. You may be wondering what exactly is the benefit of a display having a low input lag?

The primary benefit of a low input lag is that it improves the gaming experience when using the display to play games. To be more specific, since most game consoles use wireless gamepads, the display will take just a few milliseconds to register an input from the gamepad.

Thus, improving the overall gaming experience. With all that being said, it is okay to say the VIZIO D65x-G4 is an ideal television for gamers.

All things considered, I will rate the VIZIO D65x-G4 an eight out of ten in this display review section.

D65x-G4 Sound Features Review

The VIZIO D65x-G4 wouldn’t win any award or even be considered when it comes to the sound department. To be more specific, this TV comes with a pair of 8-Watts speakers that produce somewhat mediocre sounds.

Also, due to the fact that this television lacks a subwoofer, bass is totally absent on the TV. Therefore, watching bass-heavy movies on the VIZIO D65x-G4 isn’t a good idea.

On a positive note, the TV comes with DTS Studio Sound II technology that helps improve its speakers’ mediocre sound output. Specifically, this sound technology enhances a speaker’s performance by creating a cinematic sound effect.

Also, this sound technology allows the VIZIO D65x-G4’s speakers to produce crisp and clear dialogue. Just to be clear, dialogue is the conversation between two or more characters in a movie or TV show.

Moving on, despite producing clear dialogue, distortion will be an issue with the VIZIO D65x-G4. To give more details, the distortion that the VIZIO D65x-G4’s speakers produce is much.

Specifically, if the volume of the TV is over 70%, distortion will be significant. However, distortion will reduce if the television’s volume is at a moderate level, specifically below 50%.

For clarity, distortion in this context is simply the deformation in an audio signal’s output. In other words, distortion alters the sound production of a speaker, causing it to produce less-appealing sound.

In conclusion, dialogue might be clear on the VIZIO D65x-G4, but overall sound output is somewhat poor. Thus, I recommend connecting a soundbar to this television to get a much better sound output.

After thorough consideration, I will rate the VIZIO D65x-G4 a seven out of ten in this sound review section.

D65x-G4 Ports and Connectivity Features Review

VIZIO D65x-G4 Ports And Connectivity Features Review

Ports on the VIZIO D65x-G4 are divided into two segments on the television’s back panel. Specifically, some ports are down-facing, while some are right-facing.

However, the amount of ports on this television is minimal. To give more details, this television has only two HDMI ports, none of which support ARC (Audio Return Channel).  

To make matters even worse, this TV doesn’t feature a single USB port. On a positive note, the television comes with a composite video input with L/R audio.

In addition to its composite video input, the TV also feature an Ethernet port for wired internet connectivity. For wireless internet connectivity, the VIZIO D65x-G4 comes with 802.11ac Dual Band WIFI.

However, the television lacks Bluetooth.

Moving on to the remote, the VIZIO D65x-G4 comes with a basic XRT136 remote control. This remote is made of plastic and has a sleek black finish.

Furthermore, this remote features quite a number of dedicated buttons for quick access to streaming apps. A few streaming apps that have dedicated buttons on this remote include Netflix, Vudu, and Numo.

It also includes Amazon Prime Video, Crackle, and IheartRadio. Above these dedicated buttons are the input button and power button.

The navigation button on this remote is placed a little above the center. Below this navigation button is the volume and channel rockers.

Impressively, this remote control also comes with a full number pad. Also, there is a “VIZIO” logo finely printed on the bottom of the remote.

All things considered, in this port and connectivity review section, I believe the VIZIO D65x-G4 doesn’t deserve a rating of more than seven out of ten.

D65x-G4 Smart Features Review

Just like any other VIZIO smart TV, the VIZIO D65x-G4 comes with the VIZIO SmartCast operating system. This operating system features an interface that consists of a settings menu, a full app menu, and a quick app menu.

Additionally, this operating system’s interface is user-friendly, simple, and straightforward. This simple interface, however, is affected by stutter and lag.

To give more details, the interface is slow to respond to input, and the animations are a bit choppy. Notwithstanding, the interface is fully functional and does not crash, although navigation will be a struggle.

Moving on, the SmartCast operating system features a few pre-installed major streaming apps like Netflix and YouTube. However, the operating system’s app store has a limited number of apps. 

Thankfully, the television comes with an in-built Chromecast that offers the majority of the streaming apps available. However, to use the in-built Chromecast, users have to “cast” the content from the streaming app from their smart device to the television. 

In summary, the VIZIO D65x-G4’s SmartCast OS isn’t particularly impressive, but it is efficient. Besides, the television features an in-built Chromecast to support this operating system.

With all these in mind, I will rate the VIZIO D65x-G4 an eight out of ten in this smart features review section.
