LG OLED 65G16LA Lab test: almost perfect images


LG’s first 65-inch OLED EVO TV, the 65G16LA pushes the limits of display technology even further with a new panel, but also a latest generation processor and the latest version of the famous WebOS system. We were able to test it in our Lab.


As efficient as it is, OLED technology is often criticized for its low peak in brightness. A defect that LG is working to correct with its new EVO range, which benefits from a panel that is theoretically brighter than previous generations. Having already tested the LG OLED 55G16LA which sets the bar very high, this time we focused on its 65-inch big brother.


A television that shares the same attributes, starting with the design. OLED has the advantage of offering extremely fine “form-factors”, and the manufacturer does not deprive itself of it with the LG OLED 65G16LA. The 4 Cinema Screen frame is reduced to its simplest form, and the effect is striking once the device is hung on the wall thanks to the wall bracket. This takes advantage of a space in the chassis of the LG OLED 65G16LA so as to press the latter against the wall. Other side of the coin: the feet are only available as an option.


Like the LG OLED 55G16LA, the LG OLED 65G16LA lacks nothing in terms of connectivity. The four HDMI inputs are all version 2.1 (and two ARC compatible), opening the door to 4K content at 120 frames per second and VRR, ALLM, Nvidia G-Sync, AMD Freesync Premium functions for video games. The TV also has three USB ports on the side, optical digital audio out, headphone out, Ethernet port, CI + port, and antenna connectors. Everything is completed by wireless connections with Wifi ac on the one hand (but still no Wifi 6), and Bluetooth 5.0 on the other.


The LG OLED 65G16LA is powered by the latest version of the WebOS operating system. This is accompanied by many new features, starting with a radical change of the interface. The home screen, which groups the personalized content recommended at the top of the page, displays the applications in a banner. However, unlike previous iterations of WebOS, it is no longer overlaid on the image to navigate the interface while continuing to watch a program. A dashboard for the home is also appearing. In particular, it gives direct access to the TV inputs, but also to the settings. These then occupy a part of the screen so as to visualize the modifications on the image.


LG is also not giving up on the Magic Remote, which is the lifelong companion of its WebOS system. As a reminder, all you have to do is point it at the screen and move it like a magic wand to animate the cursor on the screen. Operation is very intuitive once you get used to it. Especially since the shape of the remote control evolves for a better grip.


Finally, to consolidate its premium positioning, the LG OLED 65G16LA offers all the current features. Whether it’s the Google Assistant and Amazon Alexa voice assistants or Google Cast and AirPlay 2 for streaming content from a mobile device, there’s nothing missing.


Before going into the actual tests, remember that the LG OLED 65G16LA has a new generation Alpha 9 processor. More efficient, it is in particular in charge of analyzing the images in order to improve them thanks to artificial intelligence. However, our tests are carried out by deactivating the various modes and effects, so as to put all televisions on an equal footing.



The contrast of a screen is its ability to display very dark and very bright images. We speak of contrast ratio (the ratio of light intensity between the whitest point and the blackest point).
* OLED screens display no light in the dark, so no contrast ratio is calculable.

While the LG OLED 55G16LA displays a brightness of 164 cd / m2 in the center of the panel, the LG OLED 65G16LA must be content with 131 cd / m2. This nevertheless represents a significant gain compared to the previous generation models that we tested. Unsurprisingly, the blacks are perfect, the OLED panel completely turning off the pixels. No light leakage is to be deplored and the LG OLED 65G16LA displays an exceptional contrast ratio.



This is the measure of gradients. Each level of gray should neither be too light nor too dark.

The progressiveness of the LG OLED 65G16LA is evaluated in two stages. First with a reading of the level of light emitted as a function of the control level of the panel, that is to say the comparison of the gamma curves: that of the video signal at the input on one side, and that at the output of the TV on the other. The latter must restore the source with as little alteration as possible, which visually translates into two curves as parallel as possible. There is nevertheless a slight shift at the bottom of the curve. Nothing really annoying when using the LG OLED 65G16LA, but enough to lose a few points.

Secondly, we carry out progressivity measurements under five observation angles. It is a question here of simulating the various points of observation of the televiewer. The OLED EVO panel of the LG OLED 65G16LA allows it to display a uniform level of brightness in the axis and in the angles.



Be able to watch the screen regardless of the viewer’s position (keep the same image quality from the front as from the sides) * OLED screens have no backlight, so there will be no leaks light in the dark

During the directivity test, we evaluate the drift in color as a function of the observation point. The scan is carried out on several points with different observation positions. This test, which makes perfect sense with LED televisions, has little interest on an OLED panel. Indeed, the self-emissive pixels are off when they should display black. Whatever the viewing angle, the blacks are therefore perfect, at 0 cd / m2.

We measure the fidelity of the color. The higher the score, the closer the colors are to reality

We often say that OLED has the advantage of displaying extremely rich and faithful colors. And it is not the LG OLED 65G16LA that will make us say the opposite. Proof with the DCI-P3 reference triangle below. The TV goes much further, especially in the greens and blues. Add to that a practically non-existent colorimetric drift and you have one of the most successful televisions on this precise point.

An image of the same quality, color, luminance over the entire surface of the panel

Finally, the LG OLED 55G16LA also obtained excellent results in our uniformity tests. With a larger panel (65 inches against 55 inches), the LG OLED 65G16LA therefore had a lot to do. However, the TV does even better, with a difference in luminance uniformity of only 6% (10% for the LG OLED 55G16LA). A negligible value which allows him to obtain a score of 10/10 during this test. The brightness is at its maximum with 142 cd / m2 in several areas of the panel, while the minimum of 134 cd / m2 is reached near the upper right corner. Clearly, the LG OLED 65G16LA displays uniform brightness.

However, the difference in chroma uniformity is a little more marked with a delta U’V ‘of 0.0066 against 0.0036 for the 55 inch. The LG OLED 65G16LA therefore does a little worse than its little brother during this last test. But not enough to spoil the pleasure of the viewer.
