The 40-43” size is slowly losing the focus of manufacturers. Manufacturers and buyers are focusing on larger TVs (see our recommendations for the best 55 inch 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 24 TVs in 2017 and 2018 that are available in these sizes and below are our recommendations for the best 40-43 inch TVs.
Note: Prices and availability fluctuate a lot at the end of the year and especially after Black Friday.
The best 43 inch 4k TV is the Samsung UN43NU7100. Although the NU7100 has just a decent picture quality, the dark room performance is great due to the deep and uniform blacks. It is a very responsive TV with a very low input lag which makes it a good choice for those who want to use it for gaming or as a PC monitor.
Unfortunately, the pixel response time is not very fast and a slightly longer blur trail is obvious behind fast moving objects.
Overall, the Samsung UN43NU7100 a decent entry-level 4k TV that will keep most people happy.
If you want better dark room performance, get the Vizio E43-F1. You will not get the good gray uniformity of the Samsung, but the Vizio E Series 2018 is a good 4k VA TV with deep, uniform blacks, and very good reflection handling. Gamers will appreciate the fast response time and the low input lag, which also means it feels responsive when using it as a computer monitor. Unfortunately, there isn't much advantage to HDR, as it doesn't have a wide color gamut and it can't get very bright in HDR, so small highlights don't stand out as much as they should. Overall, it is a good entry-level 4k TV that should please most people, but it is very hard to find.
If you often use the TV as a PC monitor and find that the viewing angles of the Samsung NU7100 are inadequate, then get the Sony KD43X720E. You will not have the deep blacks of the Samsung since the Sony TV has an IPS panel which makes the image washed out in darker rooms. On the upside, the Sony X720E is a decent entry level 4k TV with a low input lag that you can safely use as a PC monitor or for gaming. It has wide viewing angles that prevent uniformity issues at the edges of the screen when you view the TV from up-close. Lately, it has become hard to find.
If you want a better smart feature platform than the one on our top pick, get the TCL 5 Series 43S517. You might experience more uniformity issues with the TCL 43S517 than with the Samsung NU7100 and dark scenes on the Samsung 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 also looks 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 one of the best 43 inch smart TVs 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 43S405/43S425. You will not get the more advanced motion interpolation feature or the same good brightness as the S517. On the upside, the TCL S403/S425 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/S425, then get the TCL 40S305/S325, 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 has some excellent smart features.
Our recommendations above are what we think are currently the best 40-43 inch TVs 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).
