So, about the Hisense 43R6G TV: while it does support HDR (High Dynamic Range), it doesn't have Dolby Vision.

According to the manufacturer's product description, the TV is equipped with HDR10 to enhance your viewing experience. This tech improves contrast and color, giving your movies and shows a more vibrant and lifelike look compared to standard definition.

The TV runs on the Roku OS platform, which is great because you get a ton of streaming options with an easy-to-use interface. Many people found the Roku interface to be straightforward, and it's especially handy for accessing HDR content.

Just a heads up though—if having Dolby Vision is a big deal for you, you might want to look at some other TVs.

But if you're good with HDR10, this TV is a decent pick, especially considering all the streaming capabilities it offers. Just make sure the shows or movies you want to watch are available in HDR on your streaming services—then you can really get the most out of it!

The sound quality on the Hisense 43R6G TV seems to be a bit of a mixed experience. The manufacturer mentions that it has DTS Studio Sound technology, which aims to provide a more immersive audio vibe. However, like many TVs with built-in speakers, it might not hit the mark for everyone, particularly if you're really into sound quality or enjoy richer audio.

From what we've gathered, the sound should be fine for everyday watching. But, if you're planning to watch a lot of movies or listen to music, some folks have noted it might lack that full depth and bass. This isn't unusual with flat-screen TVs since their design often limits the size of the speakers.

If you're thinking about improving the sound, adding a soundbar or an external speaker system could really make a difference. Many have found that this setup gives a much fuller and better sound quality, and the TV does have the outputs you need to easily connect extra audio gear.

In the end, if simple sound is all you need, the Hisense 43R6G's built-in speakers should work just fine.

But for a juicier audio experience, especially if you're into movies or gaming, getting some external speakers could be a game-changer. Just keep in mind, the room setup and where you place everything can also affect how the sound turns out.

The Hisense 43-Inch R6 Series 4K UHD Smart Roku TV, or the 43R6G, has some solid picture quality features that are worth mentioning. The TV uses the Roku interface, which is pretty intuitive and lets you access lots of streaming channels without much hassle.

In terms of picture quality, this TV does a good job delivering vibrant colors and decent contrast because of its 4K resolution and HDR support. The manufacturer mentions that it supports Dolby Vision HDR, which means you'll get more colorful and detailed images in both dark and bright scenes.

However, from what we found, the peak brightness might not reach the same levels as some more expensive models, so it might not be ideal for really sunny rooms. It truly shines in rooms with moderate to low lighting where you can appreciate the color and contrast better.

The sound from its built-in speakers, aided by DTS Studio Sound, is okay for normal use. But if you're a fan of booming sound, especially during action movies or games, you might want to think about adding a soundbar. It seems that some folks have suggested this based on their experience.

Just so you know, this TV doesn't have every high-end feature you'd expect in premium models, like a 120Hz refresh rate or local dimming. But for a reasonably priced 4K smart TV, it's reliable and gets the job done.

It even has a Game Mode that helps reduce input lag, which is great if you're into gaming.

So, if you're after a budget-friendly TV that still packs in some solid 4K capabilities and smart features, the Hisense 43-Inch R6 Series might be a good fit. According to our research, it's an excellent value for the price, providing a straightforward and enjoyable viewing experience without all the extra cost.
