Buying a New TV

Most people are watching TV at home when they have nothing to do because it is very entertaining. Moreover nowadays you can find plenty of streaming services that offer tons of shows or movies both new and old titles to enjoy. We can break free from our routine by watching any of these shows but, not only the titles or the actors and overall content quality itself, your TV will play a role as well in affecting the overall experience.

When it comes to TV, you can find lots of options out there coming from various brands that we may already recognize to those brands we never heard before. Rather than the brand you may want to choose a new TV based on what you want to achieve with this new equipment such as the image size and the panel type. The larger the panel the more expensive as well the TV will be along with the technology used to create the panel.

TV size is always the bigger the better but it is not ideal as well if you have limited space to mount them. In a larger room and the more people watching the TV, the larger the TV needs to be so everyone can get at least decent detail and the same image quality to those sitting right in the front of the middle of the screen. The longer the distance from the viewer the bigger as well your TV needs to be.

Usually people buy a new TV to upgrade the size or the panel tech so you can shop based on the one we have at home already whether it is too small or the color seems off and the pixel looks too big for your viewing distance. Getting a larger TV is fun, moreover if you are upgrading from HD to 4K panel since the difference will be very visible. The 4K panel has more pixels so they look better even from a closer distance.

In addition, the panel technology matters too. An OLED panel for example is what you will want to have if best image quality is the first consideration. This technology will give you a very deep contrast or infinite contrast because it has its own light than an illuminating panel. The cons are they are also the most expensive and a new model will be twice or cost more than a regular panel at the same size. The choice is all yours so we should shop based on which seems to meet your expectation.

About Sony A90J and LG CX

If you are here then it means an OLED display is what you are aiming to get this time and with companies competing against each other to offer the best, we have plenty to consider and choose from, which most likely to be very similar to each other. You can shop based on the brand, TV size, budget, or panel type, etc. that seems to match with your current need. But, if you want to be convenient, we can just decide to choose from one or two brands.

This way we can quickly decide which TV to buy or which of them will be more promising and among those many manufacturers, Sony and LG are always carrying some of the best our current tech can offer. These brands are very easy to find so you can buy them almost from any electronic store while at the same time having a wide range of options to consider whether it is budget choice or those on the more expensive range, including OLED display.

For those who want an OLED display, Sony A90J and LG CX are two great options to buy today. They are not cheap, for example the 55-inch of A90J is currently $2,700 while the same size for LG CX is about half of its price. This is because LG CX is already two years old today and A90J is still fresh which makes it understandable that it is also the more expensive choice. But, in terms of image quality they are not failing behind each other.

In comparison between the Sony A90J and LG CX, we do think you can go amazing with any of the two but with the same image quality and experience, we also recommend getting the LG CX as long as you can still find the new product today because the biggest challenge of waiting for a good TV to be affordable enough to buy is because it will be difficult to find later as the company release their new series to replace it.

Sony A90J and LG CX Design

From the outside, these TVs are very pretty and the first thing we notice from them is the thin bezel, equal all around the screen and is the same at 0.3 inch or 0.9 cm. The black finish makes these TVs almost look bezel-less when in off condition but even while powered, the bezel is already looking very thin. The overall housing is very good but in comparison the LG CX top area is so thin that it can flex when you put pressure on the panel.

Sony A90J is overall thinner even on the thickest part since LG CX is thick at the bottom of the panel. The build quality of A90J is impressive despite being made mostly out of plastic. As for the stand, we found both to be very stable and there is no worrying wobble as well when you place them on a flat surface, including for LG CX because it only uses a single wide flat stand to support the unit.

Sony A90J and LG CX Panel Type

Now for the most important part, let’s see what Sony A90J and LG CX can offer starting from their panel technology. But, being an OLED display the two are very similar to each other and to many other OLED TVs from other brands. Being able to switch off their light source individually makes these panels achieve a high level of blackness. Even though there are probably differences even among the same series, the two are capable of delivering a very deep contrast for your experience.

Sony A90J and LG CX Image Quality

On the image quality, they are superb but are not exactly the same because we notice that LG CX is just slightly brighter in comparison than A90J which in general is always the weakness of the OLED panel because they can’t get as bright as regular TVs. But, when you activate the gaming mode, Sony is the one that is a bit brighter than LG CX. When it comes to viewing experience, they are the same as well, much better viewing angle and less reflection shown on the surface.

Viewing angle is an important factor when buying a TV because not everyone will watch them alone or with only two to three people in the house. The more the people watching it, the further away they may sit from the center of the TV and poor viewing angle can reduce the experience of other users who are sitting on the left or right side of the sofa because the color looks different from how they should be.

Sony A90J and LG CX for Gaming

Lastly on the gaming performance, both Sony A90J and LG CX are also very similar with a very low input lag. Out of gaming mode, the lag is quite high in Sony at 168.6 ms while on the other hand LG is only at 97 ms. When watching them at the highest resolution and frame rates or 4K 120Hz, the input lag of LG is also lower than Sony at 6.2 ms in which the latter is twice longer. In addition, LG has VRR or variable refresh rate that A90J doesn’t have and this is also very useful for people who want to game on their TV just to make sure it will be smoother.

Sony A90J vs LG CX

Both TVs are great options based on what you are aiming to have whether it is the budget or the image quality. If image quality is the most important then both Sony A90J and LG CX are two promising options to consider. They have almost the same image quality with the same level of contrast and similarly wide viewing angle but LG panel is just slightly brighter than Sony. For gaming purposes, LG is also the one with lower input lag in addition it also has VRR for improved experience or smoother gaming performance.
