In August 2016, the Xbox One S was one of the first gaming consoles capable of 4K streaming, but not 4K gaming. In November of the same year, the PlayStation 4 Pro launched with 4K gaming and streaming features. Soon after the announcement of the Xbox One X a year later, finding the cheapest 120Hz 4K TV at the time meant coughing up plenty of cash.

Which is the Cheapest 120Hz 4K TV

Although the display technology has been in play for decades, it seeped into the mainstream back in 2010 when the popular video-sharing platform, YouTube, allowed users to access Ultra High Definition content. Consequently, you did not have to depend on dedicated equipment to take advantage of the high resolution. Eventually, the prices of 4K TVs began to fall drastically as the technology continued to mature because more manufacturers wanted to produce options for the growing market.

Currently, budget TV options capable of 120Hz and 4K are pretty common. Of course, these products are higher priced than counterparts offering a resolution of 1080p. However, the recommendations below will help you get excellent quality while not breaking the bank.

As for the downsides, local dimming on the LG 55NANO85UNA is pretty weak. Consequently, black uniformity suffers, making it difficult for the panel to balance the backlight and dark areas. Consequently, watching movies in dark rooms is not this TV's strong suit.

Key Specifications

This model features gaming features like Auto Low Latency Mode, low input lag, Game Mode Pro and two HDMI 2.1 ports. However, there is a performance gap when you connect next-gen games consoles like PS5 or Xbox Series X. Unfortunately, the TV fails to take advantage of the 120Hz refresh rate with Variable Refresh Rate since HDR does not work under these circumstances. Consequently, it gets pretty blurry with a lot of ghosting when gaming or hooking it up to your PC like a monitor.

Key Specifications

  • Ports: 1 digital audio output, 1 earphone output, RCA video and audio input, 1 RF antenna, 1 USB 2.0 and 1 USB 3.0, 2 HDMI 2.0 and 2 HDMI 2.1 ports.
  • Display Technology: LCD panel with ULED proprietary technology.
  • Peak Brightness: 1500 nits.


  • High peak brightness.
  • Dolby Vision HDR.
  • You get a low input lag of fewer than 20 milliseconds in the game mode.
  • It offers an impressive viewing angle of 178 degrees.
  • Full array local dimming zones totaling 132.Cons


  • Narrow viewing angles.
  • It is not ideal for console or PC gaming at 4K with a 120Hz refresh rate.

The TCL 6 Series 55R635 has plenty of features that make customers rave about its impressive picture quality at a bargain. This panel combines a mini LED backlight and Quantum Dot technology to create a blend that ensures you see a minimal halo effect when bright objects interact with the inky black background. In addition, the independently controlled zones ensure a high contrast ratio close to what OLED TVs offer.

Whether you want to put your TV on a wall with a standard VESA mount of 300mm x300mm or let it sit on a stand, it will look pretty futuristic. The legs help you with cable management, although you will need thin wires if you want to use all the ports simultaneously. Plus, the shiny finish on the chassis looks sleek with slim bezels that pull your attention to the smart TV.

Admittedly, this TV does not feature any HDMI 2.1 ports since attaining the 4k resolution limits you to a 60Hz refresh rate while 120 Hz gives you 1440p. Consequently, it may not be ideal for PC gaming or next-gen consoles rated for the refresh rate and resolution. Nevertheless, it features the THX-certified game mode making it excellent for gaming.

Key Specifications

  • Ports: 1 USB port, 3.5 mm jack, AV input, TOSLINK connection, an Ethernet jack and 4 HDMI ports.
  • Display Technology: a QLED panel with mini LED backlights.
  • Peak Brightness: About 1000 nits in HDR and 700 for SDR.


  • Despite lacking a single HDMI 2.0 port, the TV supports Auto-Low Latency Mode, Variable Refresh Rate and a reduced input lag of 21.5 milliseconds.
  • It has Roku TV for access to streaming services like Prime Video.
  • Excellent remote.


  • It lacks HDMI 2.1 ports.
  • You can spot some color banding when you are close to the TV.
  • The sound is not particularly loud.

Although this is the smallest TV on our list, the 43-inch screen size in the Sony X85J, the 4k UHD resolution and 120Hz refresh rate makes it an ideal choice for sports enthusiasts, movie buffs and gamers. In addition, this smart TV has Motionflow XR and Triluminos Pro technologies for smoothing motion and reproducing a wide color gamut for your viewing pleasure. Furthermore, the 4K X-Reality Pro is excellent at upscaling HD content to bring out vivid details and textures.

This panel's contrast is exceptional despite the lack of local dimming zones. Hence, the bright sections leak into the blacks while the grayscale lacks proper definition between different shades. In addition, the viewing angles are pretty poor, so you do not have free range on where to sit when enjoying media content on the smart TV.

4K upscalling works brilliantly.

Should You Prioritize 4K Resolution at 120Hz for a TV?

Although 120hz 4K TVs represent the current top tier in consuming media at home, there are other features to consider before buying one. In addition, whether you plan on playing games or streaming video content, your choice should fit your use and offer versatility. Plus, you need it to be bright enough for your living room or bedroom, regardless of the usual lighting conditions.

Buying 120Hz 4K TVs will ensure you can consume what the future of entertainment offers. Moreover, you can take advantage of these specs through some modern games and streaming services with a new TV so that you do not need an upgrade soon. But, of course, since most modern TVs are pretty pricey, you can rely on quality budget models for future-proofing.

Display technologies are crucial to figuring out whether you'll get wide viewing angles, deep blacks and sufficient brightness on your panel. OLED tech is at the echelon of picture quality, but their price tags are often prohibitive. Fortunately, many manufacturers are going around the cost issue by combining LCD panels with either mini LEDs or other technologies.

Hence, you can get an affordable TV that is surprisingly close to the image richness of OLEDs. After all, when you are chilling in your power recliner at the side and getting a warm massage, you should not have to move to see the images better. Plus, we can advise you on where to position your TV for the ultimate viewing pleasure.

Finally, it is advisable to comb through reviews when shopping for a TV, as user feedback can help you determine your option's suitability. Whether gaming, cinema or using the panel as a PC monitor, some choices may be better at some things and poor at others. So, unless you can stretch deep into your pocket for an OLED, take time to understand what you are in for before the purchase.
