The 48-49-50 inch sizes in TVs are becoming more uncommon. In 2018, only a few of the TVs we've tested are available in a 48-50 inch size, while the 55-inch size is a lot more popular. However, you can still find some great TVs if you have limited space.
Note: Prices and availability fluctuate a lot at the beginning of the year as last year's models are gradually replaced by newer ones.
The best TV available in a 48-49-50" size is the Sony XBR49X900F. The X900F is a great, well-rounded TV with excellent dark room performance and outstanding motion handling. It has an excellent fast response time and nearly flicker-free backlight. It has great low input lag, which is important for gaming or when used as a PC monitor.
Unfortunately, the X900F has bad viewing angles, and the image degrades rapidly when viewed at an angle. The local dimming feature is decent but can be a bit too aggressive, causing a loss of fine details compared to better local dimming found on high-end TVs like the Sony Z9F.
Overall, it is a great TV that should please most people, regardless of usage.
If the narrow viewing angles of the Sony X900F are a problem for you, then get the LG 49SK8000PUA instead. The SK8000 has much wider viewing angles, great if you have a wide seating arrangement or like to move around while watching TV. Dark room viewing isn't as good as with the X900F since the contrast ratio and local dimming of the SK8000 are worse; however, it is a better choice for gaming, as it has better low input lag and a more advanced black frame insertion feature that can improve the perceived clarity of motion.
If you want a TV to use for gaming and find that the input lag of the Sony XBR49X900F is not satisfactory, then the best gaming TV available in a 48-49-50" size is the Samsung UN49NU8000. You will not get the fast response time or the effective local dimming of the Sony. On the upside, the NU8000 is packed with gaming features like support for AMD FreeSync VRR, low input lag in motion interpolation, and auto low latency mode that automatically switches into game mode when it detects you are playing a game.
If you find the Sony X900F too expensive, the TCL S Series 49S405/S425 is the best 49 inch TV in the budget category. The S405/S425 performs decently in most usages but lacks the more advanced features found on more expensive models. It has a fast response time and an excellent low input lag and it is very responsive, which is great if you plan to use it for gaming or as a PC monitor. At the same time, it can display deep blacks in a dark room even though it does not have a local dimming feature.
Unfortunately, It isn't bright enough for very bright rooms, and it cannot get very bright in HDR so you will not benefit very much in using it in this mode.
Overall, the TCL S Series 49S405/49S425 is a TV that performs decently in most usages.
If you want a good budget TV with wider viewing angles than the TCL 49S517, check out the Sony KD49X720E. The X720E uses an IPS panel and has very good wide viewing angles, great for a wide seating area or if you like to move around the room with the TV on. It doesn't perform well in a dark room, as blacks look gray and it has poor black uniformity. For gaming, it delivers similar overall performance to the TCL S517, with excellent low input lag and a fast response time.
