Why Smart TVs Get Slow
Expert Take
The 'Smart' software on TVs stops getting updates after 2-3 years. The processors inside are generally weak and underpowered from the factory. As apps like Netflix and YouTube get updated with heavier code, that old processor chokes.
Fire TV Sticks are dedicated computers that bypass your TV's slow brain entirely. By plugging it into HDMI 1 and setting your TV to auto-launch that input, you are effectively giving your screen a brain transplant. The 4K Max is currently the best value upgrade—its 2GB of RAM makes menu navigation instant compared to the laggy interface of a 2019 Sony or Samsung TV.
