The 40-43” size is slowly losing the focus of manufacturers. Manufacturers and buyers are focusing on larger TVs, but even though you will not find the most premium models among these sizes, there are still some good TVs to choose from.
We've tested 21 TVs in 2017 and 2018 that are available in a 40-42-43" size and below are our recommendations for the best ones to buy in 2018.
The best 43 inch 4k TV is the Vizio E Series 2018 (E43-F1). It is a good 4K UHD TV with decent picture quality that can display deep blacks in dark rooms due to the excellent native contrast ratio. It also has some more advanced features to improve picture quality like local dimming, aimed at improving blacks. The Vizio E Series 2018 has a very low input lag and a very fast response time, which is great for gamers.
Unfortunately, the image quality degrades when viewed at an angle and the Vizio E43-F1 does not include a motion interpolation feature to please those who like the soap opera effect.
Overall, it is a good 43 inch TV that will keep you happy.
If you watch a lot of TV shows, get the Samsung UN40NU7100 instead of the Vizio E Series 2018 E43-F1. You will not have features like local dimming, but the Samsung is a decent 4k LED TV with decent picture quality and deep blacks. It is a great option for those who enjoy TV shows as it has good reflection handling and a low input lag, which is good for gamers.
If you find that the Vizio E Series 2018 E43-F1 has poor viewing angles and you want a 40-43” TV that you can view from the side, then we recommend the Sony KD43X720E. It has decent viewing angles and is an entry level 4k TV with low input lag that will please gamers. The IPS panel does not allow it to produce deep blacks and thus the picture quality in a dark room is mediocre. You will be getting the most of this TV if you place it in a brighter room where you can also accommodate wider seating arrangements.
If you find that the Vizio E Series 2018 E43-F1 does not have a conventional smart feature platform, then get the TCL 5 Series 43S517. You might experience more uniformity issues with the TCL 43S517 than with the E43-F1 and dark scenes on the Vizio look more uniform with less clouding.
On the upside, the TCL S517 has the Roku smart features platform and is great for gaming as it has a very low input lag. HDR content will also look better on the S517 due to the wide color gamut. This TV has a high native contrast ratio that makes blacks look deep in a dark room just like more expensive models such as the TCL R617, which is not available in a 40-43” size.
Overall, the TCL S517 is a great 43 inch TV that offers many of the options found in larger models for a fraction of the price.
If you want a cheaper alternative than the TCL 43S517 but are not willing to compromise in picture quality, then get the TCL 43S405. You will not get the more advanced motion interpolation features or the same brightness as the S517. On the upside, the TCL S403 is great for gaming as it has very low input lag, it displays deep blacks in dark rooms due to the great native contrast ratio and has low motion blur that keeps fast content clear. Unfortunately, it has become hard to find.
If you want an even cheaper alternative than the TCL 43S405, then get the TCL 40S305, which is quite similar. It is a basic 1080p TV with minimal settings and no HDR support and it cannot get very bright. On the positive side, blacks are deep and are reproduced well, and the TV uses the Roku interface that provides it with excellent smart features.
Our recommendations above are what we think are currently the best 40-43 inch televisions to buy for most people in each price range. We factor in the price (a cheaper TV wins over a pricier one if the difference isn't worth it), feedback from our visitors and availability (no TVs that are difficult to find or almost out of stock everywhere).
