Design
GX: Gallery design
With a thickness of only 2 centimeters, the GX is very suitable for mounting on the wall. LG calls this design the Gallery design. With the included wall mount, you can hang the TV tightly against the wall. The thin bezel around the screen also contributes to this neat design. With LG's gallery mode, you can show photos on the TV. The TV hangs on your wall like a painting. Note: a stand isn't included with this TV.
CX: Thin screen with wide stand
With over 4.5 centimeters, the CX is slightly thicker than the GX. This TV stands on a wide brushed metal stand, which protrudes slightly at the front. The stand is slightly larger at the back, so the television stands firmly. You can also hide your cables in this stand. This way, you won't see a tangle of different cables at the back of the TV. The screen itself is very thin, sticking out above the slightly thicker plastic back.
Size
GX: available in large sizes
The GX is available in 3 different sizes. The smallest size of the GX is 55 inches, or 140 centimeters. The middle size is 65 inches, which is equivalent to 165 centimeters. The 77 inches, or 195 centimeters, is the largest size of this TV. So you can be sure that you get a larger television for your home with the GX. The stylish design also comes into its own in these sizes. This way, you have a real eye-catcher on the wall.
CX: available in a smaller size
The CX is available in the same sizes as the GX, but this OLED television is also available in a 48-inch size. This size is useful for smaller rooms or if you want to use the television for gaming. With HDMI 2.1 support, you can benefit from the Variable Refresh Rate (VRR), for example. This automatically adjusts the refresh rate of the image to the game you're playing. This way, your gaming experience is extra smooth.
Conclusion
The LG GX and CX OLED televisions offer roughly the same image quality and viewing experience. The difference is mainly in the design and the available sizes. Are you looking for a stylish and thin TV for on the wall? If so, the GX is a good choice thanks to its sleek design and the included wall mount. Do you prefer a high-quality television to use as a gaming TV or for in a smaller room? We recommend the CX.
