Things to look for in a budget 4K 120Hz TV

If you aren’t too well versed in terms of TVs, it’s easy to get overwhelmed by the simple amount of information you have at your disposal. There are too many specifications you’ll need to pay attention to, and buying the wrong TV might end up being a costly mistake. With that in mind, let’s take a look at a few things you should pay attention to when shopping.

Panel size

Arguably the most important thing to look out for when you’re getting a new TV is how big it is. While bigger is oftentimes better, there are two things to keep in mind here. First, make sure you can actually fit the TV in your designated space. This is easy to get wrong, so make sure you know the dimensions you can work with. Next up, don’t get an extremely large TV if you’re sitting close to it. The light from your TV may damage your eyesight, which you really don’t want.

Again, yes, bigger is oftentimes better, but it’s a matter of figuring out what’s the biggest you can get, without risking eyesight damage, and of course, you should be able to fit it. Then, another consideration here is the fact that a bigger TV is usually going to be more expensive, so keep that in mind, too.

Panel type

The panel type is what determines just what kind of image quality you’ll get from your display. While LED used to be the gold standard up until a few years ago, today you have a lot of better alternatives that oftentimes don’t cost all that much extra. We’re talking about OLED or QLED panels, which should be your go-to, provided your budget allows it.

While we’re talking about the panel type, we should also talk about a few other things like dimming zones and HDR. The dimming zones dictate the backlight and quality, and having more local dimming zones can ensure that you get better uniformity and better contrast. HDR, or high dynamic range, gets you more details in the brightest and darkest parts of the image, and with supported HDR content, this is a massive difference compared to a standard dynamic range. Of course, these are things that often come with higher-end TVs, so be prepared to spend a bit more if that’s your goal.

Refresh rate (and VRR)

Next up, you should take a look at the refresh rate. Yes, all the models we spoke about are 120Hz, and that’s the real refresh rate, but as we mentioned earlier, there is a lot of misleading information in that regard. But more on that in a minute.

One thing you should consider, however, is having a variable refresh rate, especially if you’re getting the TV for gaming. A variable refresh rate means that your TV’s refresh rate will be synchronized with the frames per second your console, or PC, is outputting. When those two numbers are not synchronized, you’re looking at problems like artifacts, screen tearing, and a host of other issues that are absolutely noticeable in games. When they are, however, the TV can decrease and increase the actual refresh rate as it sees fit, and you get zero problems while gaming.

Processor

You’ll notice that most modern TVs put an emphasis on their processor, and there’s one big reason for this – upscaling. At this point, we’re pretty far from all content being recorded in native 4K, which means that even with a 4K TV, some of your content will still be 1080p, or even worse, 720p. This is where the processor comes in because it uses artificial intelligence in order to upscale the content to a 4K resolution.

One thing to note here is that content that has been upscaled to 4K will never look as good as native 4K content. However, with a good processor on your TV, that quality will be good enough, and it will definitely be better than looking at content in 1080p. So, with that in mind, you should try to get a TV with a good processor that does a great job with upscaling.  

Watch out for fake 120Hz refresh rates on 4K TVs

As we mentioned earlier, a lot of manufacturers tend to include terms like TruMotion, Motion Rate, MotionFlow XR, and a host of other similar terms. After those terms, you get numbers like 120, 240, or even 480, and you’re being led to believe that that is the actual refresh rate when it’s not. The actual refresh rate is either 60Hz, or in some cases, 120Hz.

To avoid this kind of misconception, when looking at a TV, always try to research and figure out what the native refresh rate is. There, you won’t find marketing terms, and instead, you’ll be able to see what the actual refresh rate of the TV set you’re getting is. Of course, in some situations, it might not matter as much, but if you’re getting your TV for console gaming, you should definitely go for a 120Hz model.

Final thoughts

When everything is said and done, choosing one of the cheapest 120Hz 4K TVs shouldn’t be all that difficult. Just watch out for the things we mentioned above, and of course, beware of the fake 120Hz refresh rates. Once that’s taken care of, all that’s left for you to do is to pick the TV that fits your needs and budget best, and you should be good to go.
