The LG LH5700 is a budget 1080p TV. It has slightly below average picture quality when viewed from in front, but performs better than most other TVs when viewed at an angle. It handles motion very well due to the low response time. It also has low input lag and the smart features and apps work well.
The TV features a basic design, very similar to other budget LG TVs such as the UH6100. This isn't a bad thing, as it will look alright in any room. The borders and stand are made of plastic, which is quite shiny but collects fingerprints. The back has a textured finish.
The back of the TV is also quite simple. It won't turn heads but doesn't look bad. It has a textured finish, similar to the LG UH6100. If wall mounted, some of the inputs will be difficult to access.
The LG LH5700 has a below average picture quality. When viewed in a dark room, the blacks do not look really deep due to the low native contrast ratio and the lack of local dimming. The gray and black uniformity are both average. Peak brightness is not so good and here once again the lack of local dimming can't help to make small highlights brighter. The color gamut, gradient and upscaling performance are good enough for normal content with nothing bad to notice. Finally, where the LH5700 is really good is in the viewing angle, where it easily surpasses a big majority of other budget TVs.
The peak brightness performance is not really good. Situated just above the 200 cd/m² range, it will be okay for a dark room, but will certainly not be enough to fight the glare of bright lights or from a window during the day. Since this TV does not have a local dimming feature, the brightness remains the same no matter what is shown on screen.
This TV does not support HDR.
The LH5700 has poor gray uniformity. It uses a direct lit backlight and suffers from the same problem often seen in similar TVs where you tend to see darker and brighter spots where the LEDs of the backlight are situated. In that case, it is not as bad as we have seen before with other budget LG TVs, like in the case of the LH5750, but it is far from perfect. Dirty screen effect will be present in certain type of content, like in sport or in video games with uniform color background, but since the majority of the dark and uneven zones are located more on the outskirts of the screen, the dirty screen effect will be minimal.
The viewing angle is good for this LG TV. At 30 degree, it is superior to VA panel TVs but does not surpass the best IPS TVs out there or the LG OLED TVs. Colors remain the same even at a wide angle and the contrast ratio starts to go down when viewed from a very sharp angle. This will be a good choice for people with a wide seating area.
The black uniformity is below average for the LH5700. Clouding is present on almost all the screen just leaving the 4 corners dark. That being said, it is nothing unusual for an IPS TV and this one is far from the worst. When watching normal video content, the clouding is not really noticeable and should not cause a real problem here.
Similar to other LG TVs, the LH5700 has a 20 points calibration system which works well to reduce errors in the white balance. Unlike the white balance calibration, the color space calibration is less useful and is not really responsive. After calibration, the colors remain a bit off with a dE of 0.33, but for most people this is a very good result. You can find our calibration settings here.
The LH5700 has a poor color volume which is only suitable for Rec. 709 content. It can't produce very saturated colors, especially at low luminosity levels.
The LG LH5700 has some pretty strong long-lasting image retention. In our test, the retention lasted until the 8 minutes of recovery, which is a bit long when compare to other IPS TV. This is not a very good score for people looking to use their TVs as a PC monitor, since the retained image might be visible when changing content or input.
Motion blur performance is very good, due to the low response time. For fast paced content this is a good result. Movies from a blu-ray player or DVDs appear smooth. Those sensitive to judder may notice it when watching movies from another source though. Those who like the soap opera effect may be disappointed by the lack of motion interpolation features.
The LG LH5700 can play 24p content without judder without any special settings needed, so movies playing from DVDs, Blu-rays, USB drives and from streaming apps all play smoothly without any judder. Unfortunately, movies playing from 60p or 60i sources like cable/satellite/set-up boxes do present judder and there is nothing that can be done in the setting the fix this. For most people this is not noticeable. Note that TV shows are not affected by this.
Input lag is below average, which is good. It provides a similar result regardless of the picture settings. The LH5700 is a 1080p TV and so does not support any higher resolutions. It does support chroma subsampling at the native resolution for those looking to use it as a PC monitor.
Input lag is good on the LG LH5700 TV. With an average of 33ms even when on calibrated settings, this TV will be good for the average gamer. For those looking to use this TV as a computer monitor will also be pleased, at only 32.4ms of input lag when the PC input icon is selected it is also very good.
The LH5700 has a native 1080p @ 60Hz panel, and so cannot display any higher resolutions or refresh rates. It does support chroma 4:4:4, which is enabled by changing the input icon to 'PC Monitor'.
Poor sound performance. Frequency response is not good, with issues present at loud volumes. Can't get very loud, even when compared to other TVs. Even a budget soundbar is an improvement over the inbuilt speakers.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
Poor performance overall. Frequency response is sub-par, especially at moderate to high volumes where compression and pumping will be present. Additionally, maximum loudness and low-end cutoff are also poor, even for a TV.
Average harmonic distortion performance. The overall amount of harmonic distortion at 75 is relatively low. The rise in distortion at 85 and maximum volume isn't too much either. However, achieving this is not too difficult since the TV doesn't get very loud and doesn't produce much bass either.
The LG LH5700 comes with the same WebOS 3.0 used in the majority of LG TVs and you can expect the same performance and ease to use. Unlike the higher end LG models, this implemented version of WebOS 3.0 lacks the on screen pointer and it is married with a basic remote. Besides this difference, the app ecosystem remains almost the same and includes all the big streaming apps like Amazon Video, Netflix, hulu, YouTube and you can expect apps to be well maintained and to be up to date. You can also access your own videos and photos stored on an USB drive. Like the LG LH5750, this TV has only 2 HDMI and this could present some problems for people that have a wide variety of devices that use these specific ports. You can fix this issue by getting a HDMI switch.
Includes a basic remote, similar to other LG TVs such as the LH5750. It is fairly simple to use.
We tested the 43" (43LH5700). For the most part, we expect our review to be valid for the 49" (49LH5700).
If someone comes across a different type of panel or if their LG LH5700 doesn't correspond to our review, let us know and we will update the review.
The LG LH5700 is a budget 1080p TV in quite a competitive market. When viewed from in front or in a dark room it has below average picture quality. As such it doesn't really stand out from the competition, but may be a good choice for those with wider seating and on a budget. Keep this in mind when viewing our recommendations below.
