A nice image?
Don’t forget to try out the zoom 1:1 pixel mode to obtain a complete image when using this TV with a PC.
As for colors, are they deserving of the LB2R name ?
The answer is unfortunately, no! We really appreciated the color fidelity on the 32LB2R, however, on the LF65, LG chose not to carry out a factory pre-calibration. The consequences aren’t too surprising with murky grays, greens and cyan.
LG knew how to seduce us with its former 1R line and then the 2R in simple HD. Today, the Korean manufacturer presents its Full HD model equipped with an S-IPS panel and Wide Gamut backlighting. This is a first for this brand that has managed to evolved with the times by including 2 HDMI version 1.2 inputs which are 1080p and 24Hz compatible. In terms of contrast and brightness, they are rather normal, however, there is no 100Hz mode. Only the XD Engine III helps with image processing. Let’s just hope it does as well as previous models for video noise control. Finally, the new LF65 integrates a new digital TV tuner which didn’t exist on previous LB2Rs.
What can we use this TV for?
In starting tests with a digital TV source we can quickly see this brand’s mastery in terms of video noise control. Indeed, backgrounds are displayed without any grain and the XD Engine IIIIn terms of image uniformity, our test model suffered from a slight vertical banding effect. makes miracles. Nevertheless, we did start to perceive a lack of contrast. Moving on to HD sources with a Playstation 3 with a 1080p signal in 24Hz, black has a little more depth, however, it wasn’t enough. We also noticed breaks in fluidity in animated sequences, which is troubling for a television from the latest generation. Connected to a PC via an HDMI input in 60Hz, text is still readable allowing easy office use and web surfing.
Default colors weren’t too true and our sensor picked up a black of 0.8cd/m². With LG, we expected this figure to be at half this level. They announce contrast at 5000:1 and we measured 440:1. The gamut is indeed extended, however, gradation is greatly improved. Rendering of grays is too dark and this prevents the viewer from seeing certain details in dark scenes.
Fine tuning this television
You will not become lost in the OSD if you are familiar with former versions. The essential adjustments are still there and to obtain optimal colors we recommend you go into image mode User1 and then to set parameters to the following:

Translation: Contraste=Contrast, Luminosité=Brightness, Couleur=Color, Netteté=Sharpness, Teinte=Tint.
In this way, black is improved and you can then see much more detail despite contrast dropping below the 400 :1 mark. This is unfortunate, however, thanks to this adjustment blue hues are removed from most other colors. The final result is still not up to par with what this manufacturer is capable of. When you watch this TV in analog or a source connected by SCART, S-Video or even YUV inputs (in 480i or 576i), the Advanced mode becomes unblocked and you can activate the movie option which is useful for satisfactory deinterlacing.
In terms of response time, it’s fast enough not to see traces behind objects in movement. However, we are still behind the Sharp XD1Es in this domain.
-
Good video noise control with SD sources
-
24Hz compatibility
-
1:1 Pixel zoom to avoid overscan
-
Color fidelity could be improved
-
Insufficient contrast
-
Cuts in animation
-
Slight vertical banding

Rather promising on paper, the 42LF65 has a number of weaknesses that were absent on the previous 1R or 2R series. Also, while this Full HD can support the latest HD formats, images skip. This is too unfortunate.
