Slim and elegant design
For an LED-backlit LCD TV, the Q70A is incredibly thin, just an inch deep at its widest edge (bottom). It looks elegant and simple, with a barely an inch wide flat black plastic frame that extends around the edge of the screen. The bottom edge is a bit wider, but still less than half an inch thick, with a small metal rectangle protruding in the lower right corner with a multifunction power/entry/volume button underneath. The TV is placed on a relatively narrow square black plastic stand (you can also mount it to the wall).
The power cable port is located on the back of the TV, slightly to the left of the center. All other connections are located near the right edge of the screen, facing the right. It includes four HDMI ports, two USB ports, an optical audio out, an Ethernet port, an antenna/cable connector, and a 3.5mm EX-Link port for integration into RS-232 control systems.
The new Samsung Eco Remote is similarly simple and elegant. It is a thin rectangular black plastic stick with rounded sides. Feel comfortable in the hand. The design is similar to the remote control included with Amazon Fire TV devices, with a prominent circular navigation panel surrounded by a pinhole microphone, with voice assistant and power buttons above and volume and channel below. The remote also features dedicated service buttons for Amazon Prime Video, Netflix, and Samsung’s own free live TV service TV Plus (similar to Pluto TV).
The USB-C port on the bottom can charge the remote control’s built-in battery, but you don’t have to use it. Turn the remote control over, and you will see a shiny rectangle on its back. This is the solar cell for the remote control, which allows you to recharge it simply by leaving it in the sunlight. It’s a unique and eco-friendly feature, eliminating the need for batteries (plus the hassle of plugging in a remote from time to time).
Samsung Smart TV Features
Like LG, Samsung uses its own smart TV system, Samsung Tizen OS, rather than a third-party system like Android TV, Fire TV, or Roku TV. This means that the Q70A is a bit lighter in third-party applications than those TVs, but it still covers most of the basics, and has a solid set of built-in features. You can access Amazon Prime Video, Apple TV, Disney+, HBO Max, Netflix and YouTube, along with dozens of other apps and video streaming services, including streaming and playing games from your computer using Steam Link. However, Twitch is not available.
Samsung’s Smart TV platform has a lot of tricks of its own as well. It includes a web browser, an Ambient mode that cycles between artwork and images at low brightness to save power, and a Multi View mode that can display multiple sources on the same screen. It also supports screen mirroring from mobile devices and computers with Miracast / WiDi and from iOS devices and Mac devices with Apple AirPlay. Stream directly from and control your PC or Mac with Easy Connection for Windows 10 and Remote Desktop on macOS, access Microsoft 365 cloud services, and even use compatible Samsung phones as a PC with Samsung DeX. However, it is not compatible with Google Cast so you will need to use a third-party Android app to mirror the screen of your non-Samsung Android phone.
Finally, Samsung brings a lot of voice assistant support on the Q70A. You can set the TV to work with Amazon Alexa, Google Assistant, or Samsung’s Bixby. Once you have selected your preferred voice assistant, you can use it through the TV by pressing and holding the microphone button on the remote control and talking to it.
For all these features, Samsung’s Smart TV platform is arrogant and awkward. It tries to automate as much as possible, and will attempt to configure whatever new source you connect to (a tedious and unnecessary process that requires waiting for the TV to record it, unless you hit the back button on the remote to cancel it). You can’t simply jump into the input menu or the settings menu either; You need to swipe all the way left after pressing the home button, and diving into individual image settings requires navigating up via the quick access bar that pops up. The TV tries to set everything up for you and make what it thinks are the modes and settings you’re most likely to want to access readily available, but the result is a cluttered interface that doesn’t offer straightforward ways to make many adjustments at once.
Q70A Picture Quality
Samsung Q70A TV is a 4K TV with a native refresh rate of 120Hz. It supports High Dynamic Range (HDR) content in HDR10, HDR10+, and Mixed Record Gamma (HLG). It does not support Dolby Vision.
See how we test TVs
We test TVs with a Klein K-80 colorimeter, Murideo SIX-G signal generator and Portrait Displays’ Calman software using a methodology based on Imaging Science Foundation calibration techniques. The Q70A is not a particularly bright TV, especially with an SDR signal. In movie image mode out of the box, we measured a peak brightness of 244.307cd/m2, with a black level of 0.039cd/m2, for a contrast ratio of 6264:1. The HDR signal produces a significantly brighter image, with a peak brightness of 559.106 cd/m^2, but a higher black level of 0.062cd/m2 to go with it, with a 9018:1 contrast ratio. The Q70A’s backlight doesn’t use a dimmable matrix, so there’s no noticeable difference between full screen and 18% fields in peak brightness.
This is an acceptable but unimpressive performance for an LED-backlit LCD TV; Brightness levels are comparable to generally dimmer OLEDs like the excellent LG C1, but without offering the completely corresponding darker black levels. Meanwhile, Hisense U8G and TCL 6 series LED backlights show much higher brightness levels of 1,763.39cd/m2 and 1,14.9cd/m2 with levels below 0.02cd/m2 in black, for contrast ratios that It is larger than the size of the Q70A.
The Q70A performs better with color performance, but still isn’t impressive with its range. The above graph shows color levels with the SDR signal compared to the Rec.709 broadcast standards, and with the HDR signal compared to the DCI-P3 digital cinema standard. Either way, TV shows balance colors out of the box in movie picture mode. All primary and secondary colors correspond to where they should be, with no significant deviation in any particular direction. Although it doesn’t match Rec.709, it does exactly standard color levels, it comes very close. HDR performance compared to DCI-P3 is also well balanced, but the green color is not completely saturated, so the full color space is not covered. The Hisense U8G and TCL 6-Series both cover a much larger area than the DCI-P3 color space, despite Hisense’s magenta deviation in our tests.
BBC second planet earth It looks very good on the Q70A, although its limited contrast can compromise some shadow detail. Even with a slightly saturated green, the planets look lush and vibrant on TV, and the water and dark blue color of the trees are vibrant and natural. Soft textures such as fur and bark are sharp and detailed in sunlight, but tend to soften and become slightly muddy in dark shade.
Red in Deadpool’s costume in the opening scenes of dead list It looks saturated and balanced, not slightly tinted purple under overcast lighting. The flames of a smoldering lab battle are also bright and colorful, but again the details in the shadows are softened with the TV’s mediocre contrast.
Unsurprisingly, this is the case with the highly contrasting party scenes in The great Gatsby. Details like the cuts and features of the black suits are very hard to see, but they haven’t been completely eliminated; We’ve definitely seen details that are a shade more cluttered on cheap TVs. White tends to look good despite the modest luminous palette, and skin tones look natural and saturated.
Q70A gaming performance
For gaming, the Q70A features Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) with AMD FreeSync Premium, along with a new Samsung trick built into Game Mode. Upon entering Game Mode, a screen will appear at the bottom of the screen indicating the frame rate of the connected device and whether any modes such as VRR or HDR are enabled, with shortcuts to go to Game Mode settings buried in TV menus. If a compatible PC is connected, you can also set the image to 21:9 and 32:9 aspect ratios, with letterbox formatting.
These are all useful features, but the input lag is the really impressive part of the Q70A’s gaming performance. We test input lag using the HDFury Diva HDMI Matrix, and outside of game mode, the TV shows an average input lag of 66.2ms. However, switching to gaming mode brings this lag down to 2.3ms. That’s the gaming screen area, and the lowest input lag we’ve seen in a TV is in half (the LG C1 has an input lag of 4.7ms). It makes the Q70A one of the best gaming TVs that you can easily buy.
good for players
The Samsung Q70A is a solid TV with some notable aspects but the picture quality is rather mediocre. It’s packed with very useful Smart TV features, even if Samsung’s UI design is a bit snooty, and its gaming performance is the best we’ve seen. TV colors are strong and balanced, even if they don’t reach the full digital cinema color space. Contrast is its weakest point, with modest performance that can soften shadow detail, on a screen that doesn’t shine like its competitors. That caveat, along with the lack of Dolby Vision, makes the Q70A pricey at $1,100 for a 55-incher.
If you want the absolute best gaming performance on a TV, give the Q70A a look. Other than that, the Hisense U8G and TCL 6-Series both cost much less and offer much higher contrast with wider colors. And if you want to splurge and get more gaming features (specifically Nvidia G-Sync plus AMD FreeSync), consider the LG C1, which still has excellent input lag even if it’s double the Q70A, and offers nearly perfect color Out of the box with superior OLED contrast levels.
Samsung’s Q70A line of TVs doesn’t have the most impressive contrast we’ve seen, but it’s by far the fastest in terms of input lag, making it ideal for gamers.
