Panel quality and backlight features
| Characteristic | UJ65 | UJ75 | Comment |
| Backlight uniformity | 3 | 2 | slighly worse on UJ75 due to slight light bleed around the edges – on UJ65 edges just slightly darker, but not as dark as on previous LG’s direct LED IPS TVs |
| Dirty screen effect (DSE) | 3 | 3 | subtle, not distracting |
| Screen reflections | 3 | 3 | semi-glossy screen in both cases, moderately reduces glare and reflections |
| Viewing angles | 3 | 3 | good, inline with IPS technology (just a bit better on UJ75) |
| Anomalies | 2 | 2 | IPS glow, faint vertical streaks on UJ75 |
| Global/Local dimming | 3 | 3 | no global issues present, local dimming on UJ75 can be completely turned off |
| Average: | 2.83 | 2.66 |
* – grades 1-4, 1 = bad, 2 = average, 3 = good, 4 = excellent

Value UJ65 | UJ65 | Value UJ75 | UJ75 | Comment |
| Motion resolution (Monoscope test, max. 1080) | 250 max. | 1 | 250 max. | 1 | typical result for a 60 Hz LED LCD TV, no blur reduction option |
| Motion resolution (visual) | / | 2 | / | 2 | typical for a 60 Hz IPS LCD panel – loss of details in motion, doubling effect, but no significant deterioration in darker scenes (e.g. traces not becoming very long like on VA LCD panels) |

High Dynamic Range (HDR) and Wider Color Gamut (WCG) in UHD content
| Characteristic |
UJ65 | UJ75 | Comment |
| Details in shadows | 1 | 1 | due to low contrast, details not clearly presented; local dimming on UJ75 can be very distracting (especially with CinemaScope movies) |
| Details in highlights | 1 | 2 | better tone mapping on UJ75 improves picture in this aspect |
| Overall picture dynamics | 1 | 2 | due to higher peak luminance and local dimming, UJ75 is just a bit better |
| WCG – color rendering | 1 | 1 | neither is possible to display significantly more colors compared to Rec.709 |
| 24p UHD playback | 3 | 3 | very good, smooth playback with a small amount of judder (judder reduction available) |
| Banding – HDR | 3 | 3 | not noticeable steps due to 10-bit panels |
| Resolution | 3 | 3 | despite using WRGB panel, sharpness is excellent |
| Average: | 1.85 | 2.14 |
* – grades 1-4, 1 = bad, 2 = average, 3 = good, 4 = excellent
Picture quality – overall
| Overall | UJ65 | UJ75 |
| 1. Factory picture and calibration | 2.30 | 2.30 |
| 2. Panel quality | 2.83 | 2.66 |
| 3. Signal processing | 2.66 | 2.77 |
| 4. UHD, HDR & WCG | 1.85 | 2.14 |
| Total score: | 2.41 | 2.46 |
* – grades 1-4, 1 = bad, 2 = average, 3 = good, 4 = excellent
With the overall scores so close, it is clear that both models are very similar in their performance. HDR performance is also similar, but for those who are interested in the ability to playback both HDR-10 and Dolby Vision, UJ75 is a better choice.

Thank you for your work!
Where can i find the LG TV Line-up 2017 with all the details and specificiations?
Thanks!
Hi – thanks, Johannes. Here is the full lineup: https://www.scribd.com/document/358501237/LG-Lineup-Chart-2017-ENG-2-3
Zdravo Darko,
sta mislis o Lg 49uj634v za 550€ kad ga usporedis sa uj750v za 750€? Je li uj75 toliko bolji, da vredi platiti tu razliku ili koji bi drugi tv u tom rangu preporucio(a da nije android). Znam da si vec spominjao samsunge mu6000+ serije i inace nemam nista protiv ali kad sam u trgovini usporedjivao sliku modela 49mu6172 i uj634v, mi se mnogo vise svidjala slika na lgju. Na samsungu je puno vise “kocila” u brzim scenama na demo filmu. Mozda je to bila samo slucajnost. Gledalo bi se vise, manje serije/filmove preko usb-a i plex aplikacije, i sd/hd kanale, ponekad i ps4. Mozda bih dosla u obzir i 55″ velicina, jer bi se gledalo sa udaljenosti 2.2m-2.8m
Hi Darrko,
I have the same UJ7550 model, but in its 43″ version. The TV came with LG’s Magic Remote, model AN-MR650A. I’m now wondering if this remote can be a universal remote so I could use it also on my STB (from my Cable TV provider). On http://www.lg.com, they say it can be used as a universal remote, but I went through all settings, options and didn’t find a way how to set it up. Could you please help me out?
Thanks and kind regards,
Josip
Lg provides the best model of HD Tv. In this article, you describe the two model but ultra HD Lg Tv is the best t use in the home. And It review is very nice. which is very helpful to me. so, I am using the Apple TV which is working very good. if I have any problem when I go to the website https://applesupportnumber.net/apple-tv-support/ which provides the best support.
