The LG UM6900 is one of the most affordable LG TVs of the year. While it will especially please gamers and those who are looking to spend little money on a new TV, fans of brilliant picture quality will have a hard time with it. Find out more about the TVs advantages and disadvantages and why it does not offer true 4K resolution.
Design and material quality of the LG UM6900
Design and material wise, the LG UM6900 is on the cheaper end compared to other models. It strongly resembles the LG UM7300, however, it feels more plasticky and slightly cheaper. Also, the stand feel somewhat cheap and will make the TV wobble slightly, however, this won’t cause any major issues. If you decide to wall-mount it, you shouldn’t have any problems. Additionally, there is no option for cable management.
Under par picture quality
There is one striking feature that sets the LG UM6900 apart from other 4K TVs – the resolution. There is a distinct reason as to why it’s price tag is so affordable: The LG UM6900 does not offer true 4K. It uses a panel with RGBW structure resulting in fewer pixels than panels with RGB structure. Consequently, fewer pixels result in a lower resolution, meaning the image isn’t as crisp as real 4K TVs. If you’re not crazy about picture quality and only need a TV that offers a better image than Full HD TVs, the LG UM6900 is the way to go. However, if you want true 4K resolution and can spend a little more money, check out the LG UM7300, the TCL S425, or the Samsung RU7100.
Still, the built-in IPS panel delivers some great advantages. The viewing angle is very wide and the image remains accurate at an angle. Also, the brightness is high enough to perform well in brighter environments. As for darker environments, you will notice that darker colors have a slight grey tint and blacks aren’t as uniform as on VA panels. If your living room or bedroom is usually not well lit, we recommend you the Samsung RU7100 as mentioned above. Unfortunately, the contrast ratio isn’t wide enough to display HDR content impressively. HDR10+ and Dolby Vision are not supported. If that is a must for you, the Hisense H8F might be interesting.
Please note that the 60 and 70 inch models have a VA panel instead of an IPS panel. Consequently, the blacks are much more uniform and the contrast ratio is slightly wider. Unfortunately, the viewing angle is more limited.
Motion handling and gaming
Motion handling on the UM6900 is decent. It has a very good Response Time of around 6 ms, which enables the display of fast moving content without motion blur, which is great. The backlight unfortunately flickers at 120 Hz, which is also the case with the LG UM7300. Thankfully, the TV is capable of removing stutter and judder from most sources, which is great for watching movies and TV.
As for gaming, the LG UM6900 is a great affordable choice. The input lag is very low at about 10 ms with 1080p @ 60 Hz and 10 ms at 4K @ 60 Hz. Unlike other affordable TVs, the UM6900 thankfully switches into Game Mode automatically, which enables these low input lag values. This feature is called Auto Low Latency Mode. It is also great for PC gaming and for use as a PC monitor overall. VRR and HDMI 2.1 are not supported, which is to be expected in this price range.
Decent sound quality
Overall, the sound quality of the LG UM6900 is decent. If you are a normal user and like to watch a movie occasionally, you won’t find many reasons to complain. Dialogues are played back clearly and it can get loud enough for most rooms. If you are enthusiastic about great sound, however, the use of a dedicated speaker system or soundbar is recommended.
Smart TV features of the LG UM6900
As with most TVs that use LG webOS 4.5, the Smart Interface on the LG UM6900 works great. You will benefit from a great selection of apps as well as ease of use. Unfortunately, the TV comes with the basic LG remote, which cannot be upgraded. If you like the LG Magic Remote, the LG UM7300 is a better choice, however, if this does not concern you, the UM6900 is great. Most popular apps such as Netflix, Amazon Prime Video or Hulu come pre-installed. Unfortunately, Voice Control is not supported at all.
Different panels with different sizes
Please note that the different size variants of the LG UM6900 come with different panels. This may cause confusion to potential buyers. Generally, IPS panels are more recommended for bright rooms, while VA panels are better suited for dark environments. Be careful when choosing the right screen size for you.
