Film lovers can see the film as the directors intended.\u00a0Filmmaker Mode \u2122 is a new TV mode that respects the author’s intent.\u00a0It broadcasts the filmmaker’s cinematic vision to the TV with automatic picture and processor adjustments and delivers true fidelity.\u00a0In the proposed review of LG 55UN6900 TV 4K HDR, as a representative of the series, we will get acquainted with the characteristics and functionality of the new product.<\/p>\n

LG UN6900 review<\/h2>\n

Design<\/h3>\n

The appearance of the LG UN6900 is very simple and looks a bit cheap.\u00a0It is very similar to the\u00a0LG UN7300\u00a0, but it seems to be made of slightly cheaper materials.\u00a0The stand does not support the TV very well, it fluctuates quite a lot.\u00a0No cable management options.\u00a0The legs on the UN6900 are set at opposite ends of the TV, so you’ll need a large table for large diagonals unless you hang the TV on the wall.<\/p>\n

The bezels are slightly thicker than most higher end models, so they are slightly more noticeable when watching TV.\u00a0And the UN6900 TVs themselves are thicker than more expensive models.\u00a0In particular, this is due to the use of direct type LED backlighting (\u00a0Direct LED\u00a0).\u00a0Overall, the build quality is satisfactory.\u00a0There are some flexing on the rear panel though.<\/p>\n

<\/a><\/p>\n

Image quality<\/h3>\n

Like most\u00a0IPS\u00a0TVs\u00a0, the UN6900 has a disappointing contrast ratio.\u00a0The maximum value does not exceed 1000: 1. This makes shades of black appear gray.\u00a0And of course, this is especially noticeable in a dark room.\u00a0There is no local backlight dimming function that could improve contrast.<\/p>\n

Peak brightness when viewing standard SDR content does not exceed 200 nits.\u00a0Unfortunately, this TV cannot be very bright in HDR mode either.\u00a0Peak brightness hovers around 300 nits.\u00a0In Vivid mode, it increases slightly.\u00a0But still, small highlights in some scenes do not stand out as much as they should.\u00a0Plus there is a noticeable change in brightness when displaying different content.<\/p>\n

The uniformity of gray is not bad.\u00a0But still there is a “mud” effect on the screen and it will be noticeable in sports broadcasts.\u00a0In addition, the corners of the screen are slightly darker than the main body.\u00a0The uniformity of black is not good.\u00a0Blurring is noticeable all over the screen, which can be distracting in dark scenes.\u00a0Viewing angles are typical for IPS.\u00a0LG promises that color accuracy will remain unchanged up to 60-degree angles.<\/p>\n

Scaling or upscaling to 4K resolution is implemented using a 4-core processor.\u00a0At the same time, content with a lower resolution looks fine on the LG UN6900 screen, as if it were native.\u00a0As with previous models such as\u00a0LG UK6300\u00a0, the\u00a0RGBW\u00a0structure\u00a0with an additional white pixel is used, while the total number remains unchanged.<\/p>\n

\"LG<\/a><\/p>\n

This TV does not have a wide color gamut, but at the same time the color gamut is not bad – about 80% in the DCI-P3 color space.\u00a0EOTF does not follow the PQ curve properly and almost all scenes are displayed brighter than they should be, including in game mode.\u00a0But with the level of chromaticity a little worse.\u00a0Colors are not as bright as pure white, and they cannot display dark saturated hues due to low contrast ratios.<\/p>\n

Processing of moving objects<\/h3>\n

LG UN6900 has excellent response time.\u00a0Its value does not exceed 14 ms.\u00a0There is a slight blur in some transitions, which may be noticeable in dark scenes.\u00a0Backlight flickering results in noticeable outlines of moving objects (ghosting).\u00a0Unfortunately, the backlight is modulated at 100\/120 Hz even at maximum brightness.\u00a0But on the other hand, it helps to improve the clarity of movement compared to a TV without a PWM backlight.<\/p>\n

The UN6900 TV has an additional motion interpolation function that can be used to increase the frame rate up to 50\/60 frames per second.\u00a0This can improve the appearance of movement on the screen.\u00a0But it also leads to what is known as the Soap Opera Effect, and may bother some people.\u00a0There are no additional “float” on the TV.<\/p>\n

There is ALLM mode – automatic transition to game mode when the console is connected.\u00a0In this case, the minimum possible input lag for an input signal 1080p @ 50 Hz is no more than 12 ms.\u00a0Note also that the TV complies with the HGiG guidelines.<\/p>\n

Sound<\/h3>\n

The 20W UN6900 audio system has a decent frequency response.\u00a0But Low Frequency Extension (LFE) is bad, so the bass has no kick \/ rumble.\u00a0However, the mids are more even, giving relatively clear dialogue.\u00a0The TV is loud enough for small spaces.\u00a0But it is clear that the level of distortion at high volume is high.<\/p>\n

So, of course, it’s worth getting a separate soundbar at a minimum.\u00a0This will give much more effect when watching movies, especially with dynamic action.\u00a0Thankfully, LG has a decent assortment of soundbars out there.\u00a0Take the\u00a0LG SL6Y soundbar\u00a0.<\/p>\n

Smart TV<\/h3>\n

Like all\u00a02020 LG\u00a0models\u00a0, the UN6900 uses an interface on the\u00a0webOS 5.0\u00a0operating system\u00a0.\u00a0The viewer gets access to\u00a0Apple TV\u00a0apps\u00a0, Disney +,\u00a0Netflix\u00a0and LG\u00a0channels\u00a0.\u00a0There is a choice of the latest movies, TV shows, documentaries and sports broadcasts, all in one place.\u00a0True, the Disney + subscription is not pre-installed.\u00a0But every new subscriber is eligible for a one-week trial.<\/p>\n

Like all the latest LG TVs, there are ads on the home screen and content store.\u00a0These ads cannot be turned off and there is also no way to opt out of the proposed content.\u00a0The LG Content Store has one of the widest selection of apps available.\u00a0UN6900 only includes a basic remote control and is not compatible with LG Magic Remote.\u00a0The basic remote works well, but there is no voice control and requires line-of-sight to the TV.<\/p>\n

\"LG<\/a><\/p>\n

Connections<\/h3>\n

LG UN6900 TV supports Wi-Fi 802.11ac wireless communication.\u00a0There are three HDMI and two USB ports – one on the back, the rest on the side.\u00a0One of HDMI supports ARC Audio Reverse Channel.\u00a0It can transmit DTS 5.1 and Dolby Digital 5.1 audio.\u00a0The antenna jack, LAN port and optical digital audio output are also on the back, where is the composite video input.<\/p>\n

Conclusion<\/h3>\n

This inexpensive LG UN6900 TV has good picture quality, which is well suited for sports. Plus, it has the fastest game mode.\u00a0When it comes to movies and TV shows, there are screens with even higher contrast, but they also cost a lot more money.\u00a0So, overall, the 55UN6900 TV will be a good buy when it hits the stands.<\/p>\n","protected":false},"excerpt":{"rendered":"
