So here we have the NANO90. For a few years, LG has split their lineupinto three series. The OLED series like the CX and GX, then theirhigh-end LCDs which are now called the NANO series, and then their regular LCD TVs. As a result, this NANO90 is kind of an uppermid-range TV as it also sits below their OLED offerings.  we’ll put it to the test,and see if it’s the next TV you should buy! Hi, I’m Daniel from RTINGS.com where WEHELP PEOPLE FIND THE BEST PRODUCTS FOR THEIR NEEDS Make sure you subscribe to our channelfor the latest videos, or check out our website for the full review! In this video, we’ll start by looking atthe design and inputs of the NANO90, then we’ll move on to our test results for thepicture quality. We’ll also take a look at motion handling,input lag and sound. 

 We bought the seventy five inch model to test,but it is also available in a range of sizes from fifty five inches up to eighty six inches. We expect these other sizes to have very similarpicture quality. As always though, if you buy this TV and yourexperience doesn’t match this review, let us know in the comments down below! The design of the TV is good, and pretty typicalof most LG LCDs. It has a wide set stand which requires a largetable, unlike the previous model SM9000. This means you can place a soundbar betweenthe legs though. There’s a single button for controls underthe LG logo at the front of the set. You can use it to turn the TV on or off, changeinputs, volume, or channels. Moving around to the side of the TV, It hasa pretty typically thickness, at a bit less than two inches. The back is made of a smooth plastic, whichis fine and looks simple. Overall the build quality of this TV feelsonly decent. We don’t expect anyone to have problemsdue to the build, but it definitely doesn’t feel premium. The inputs are located behind the left-sideof the TV. They are directed out and down the side ofthe TV, so don’t protrude any more if you choose to mount it.

 The connections themselves are no surprise,with four HDMI ports, three USBs, an optical output and a tuner. There’s also a composite in port, and theadapter for this is included in the box. Now we’ll move on to the picture quality. We’ll be comparing to currently availableTVs but competing models may change as new TVs are released throughout the year. For an updated comparison with new modelsas we buy and test them, see the review page on our website which is linked below. First up is contrast ratio. The contrast ratio is the ratio between thebrightest white and the darkest black that a TV can produce and is generally consideredone of the most important aspects of picture quality. TV’s with a high contrast ratio appear tohave more detail in dark scenes, without those details getting lost in the gray. As with most LG LED TVs, the NANO90 uses anIPS panel. While these panels are much better for viewingangles than VA panels, which we’ll talk about more later, they tend to be much worsefor contrast, giving you poorer overall black levels and uniformity. This TV is about typical for most IPS panels. If you watch TV in the dark, then blacks willappear gray. If you’ve got some lights in your room,it isn’t a problem though. The NANO90 also has local dimming to improvethe contrast. Unfortunately, it is a bit disappointing. It does help to raise the contrast a bit onour checkerboard pattern, but in moving content the zone transitions are quite slow and noticeable,and dark scene details get crushed. Many dark details still look gray too, becauseof limitations to the IPS panel and the zone size. Now on to gray uniformity. Our gray uniformity test checks for issueswith the panel where different pixels are all supposed to display the same color, butmay not.

 This can result in distracting areas knownas the dirty screen effect, which is noticeable when watching sports or playing games. The gray uniformity on this TV is okay. The edges of the screen are visibly darkerand there’s some noticeable dirty screen effect in the center, which could be distractingwhile watching sports. So now for the viewing angles. Wide viewing angles are important if you watchwith a large group of people or have wide seating in a large room, as they allow theimage to remain accurate regardless of where you’re positioned. This TV is decent, and about typical of mostIPS type panels. The brightness does drop significantly atan angle, but most people shouldn’t have any problem watching sport with a group offriends. If your TV is in a bright room with lots oflighting, then good reflection handling is important to cut the amount of glare you seeon the screen during dark scenes. The NANO90 has great reflection handling,with a semi-gloss finish. This helps to somewhat diffuse reflectionsacross the screen and reduce their intensity. There may still be some reflections noticeablein very bright rooms, though overall it should be good enough for most situations. Also important for a bright room is the abilityto raise the brightness of the TV, to counteract glare. We measured this TV with local dimming setto medium, which is what we recommend for most people. This local dimming setting allows the TV toboost the brightness of smaller areas, like our 10% window test pattern. Unfortunately, we found this doesn’t reallytranslate to real scenes, and on our real scene test pattern we measured less than threehundred nits. This is a bit disappointing but might stillbe fine for most people due to the great reflection handling we looked at earlier. If you plan to watch HDR content, then theability to produce brighter regions of the image is important to produce impactful highlightdetail. This is one of the most noticeable reasonswhy some TVs seem to really ‘pop’ with HDR content while others don’t. This TV does support HDR, but it can’t reallyget bright enough with HDR content to really help make highlights pop. 

Also important for HDR is the ability to takeadvantage of the wider color spaces that content can be mastered in. This ‘Nano’ TV is advertised to have ‘NanoColor’, which is what LG uses to indicate their higher end wide color gamut TVs. As a result, the very good DCI-P3 performanceis not surprising, at about 90 percent of the color space. This is very similar to the SM9000 from lastyear, and helps to make vivid colors in HDR content stand out. So now onto the motion handling. There’s many aspects to motion performance,so if you want to learn more about motion on TVs then make sure you check out our videoseries up here. We’ll start with the response time. The response time of a TV is the average timeit takes the display to transition from one color to the next. A fast response time results in clearer motion,without too much trailing blur. The NANO90 has a great response time, as youcan see in our moving logo photo. There is persistence blur, but there’s onlya short smear on the left hand side of our logo. This is very good for gamers or watching sports. There’s also some flicker, but it’s notreally visible in this moving logo or in person due to the high frequency. At about nine hundred and sixty hertz, formost people it’s not a problem but it also isn’t flicker free if this is somethingyou’re sensitive to. For those who want the clearest image thoughwhen watching sports or playing games, you can also increase the amount of noticeableflicker with a technique known as black frame insertion or BFI. This is possible with the ‘Motion Pro’setting, and you can see in another photo of our moving logo that it definitely helps. It is possible to flicker at sixty hertz forsixty hertz content, so fast paced games are clear. This setting is not for everyone though dueto this introduced flicker. Also important for gamers is a low input lag. A low input lag reduces the delay betweenan action in-game and when you see it on the screen, allowing for faster reactions andmore immersion. The Nano 9 Series has an excellent low inputlag, at about fifteen milliseconds for sixty hertz signals. At one hundred and twenty hertz it drops significantlylower, down to about five and a half milliseconds. This is close to the minimum theoretical inputlag for 120Hz, which is great to see! This low input lag can also be enabled automaticallywhen starting a game – just leave the ‘Instant Game Response’ setting on the TV on. This is an implementation of the auto lowlatency mode feature introduced in the HDMI 2.1 specification. Speaking of HDMI 2.1, this TV is advertisedto support the higher bandwidth HDMI 2.1 signals on two of it’s HDMI ports – numbered 3and 4. This should allow for using the TV at 4k and120Hz, which is great for PC use or gaming, or maybe a next gen console. There are no HDMI 2.1 devices for us to testthis though, but we’ll pin a comment down below when an HDMI 2.1 graphics card is releasedand we’re able to test this feature. This TV is also advertised to support variablerefresh rates for tear free gaming. We were able to confirm support for the HDMIForum Variable Refresh rate standard via our Xbox One S, but at the moment FreeSync doesn’twork from any of our graphics cards. This is supposed to come in a future firmwareupdate.

 Now onto Smart Features. Like with all LG Smart TV’s, the NANO90uses LG’s WebOS smart interface. It has an easy to use interface, and a wideselection of available apps. Like the NANO85, this TV comes with LG’sMagic Remote which lets you easily scroll through the menus just by pointing the remoteat the TV and moving it around to move the cursor on the screen. And lastly, for the sound. You can use the magic remote to tune the frequencyresponse to your room, and overall it produces a decent result. It is of course limited by the TV’s speakersthough, which lack thump or rumble in the bass. If you care about sound, look for a soundbaror another external sound system. So overall, whether the Nano90 is a good choicefor you will depend on your use. Do you watch movies in the dark, and willbe distracted by the low contrast and local dimming? If so, probably look elsewhere for a VA typepanel like the Sony X900H or Samsung Q80T. If you’ve got a moderately lit room though,and have wide seating then it could be a good choice, and it does have some nice featuresfor gamers. So that’s it! What do you think of the LG NANO90?
