7 Secret Tech Upgrades That Will Make Your 5-Year-Old TV Feel Brand New

Nothing ages a TV faster than its built-in smart software, and nothing fixes it faster than this. The Roku Streaming Stick 4K plugs into a spare HDMI port and instantly replaces your clunky old menu with a fast, clean interface that loads apps in seconds and supports 4K, HDR10+ and Dolby Vision.

The long-range Wi-Fi receiver helps with rooms far from the router, and the voice remote can power your TV on and off and control volume, so it becomes your main remote. For around forty dollars it is the single biggest feel-new change you can make.

Bias lighting is the cheapest trick that makes a screen look more expensive. The Govee Envisual strip sticks to the back of a 55 to 65 inch TV and casts a soft glow behind it, which reduces eye strain in a dark room and makes blacks on the panel look deeper and more contrasty.

A small camera reads the colors on screen and matches the lighting in real time, so explosions and sunsets spill out around the frame. App and voice control let you dial in brightness or switch to plain warm white for everyday viewing.

Flat-panel TVs have terrible speakers, and a five-year-old set is no exception. This 120W Wohome 2.1 system pairs a 34 inch bar with a dedicated 5.5 inch subwoofer, so voices come through clearly and movie scenes finally have some weight underneath them.

It connects by HDMI, optical, AUX, USB or Bluetooth, so it works with practically any TV, and built-in DSP modes let you boost dialogue or bass to taste. For around a hundred dollars it is the most dramatic single change you can make to how your TV sounds.

Older TVs often shipped with only two or three HDMI inputs, and once a streaming stick, console and soundbar move in you run out fast. This compact Amazon Basics switch turns one input into three, passing 4K at 30Hz and 1080p without any loss of quality.

It auto-switches to whichever device you just turned on, so there is no fiddling with the TV menu to change sources. At around fifteen dollars it solves the constant cable-swapping dance for the price of a sandwich.

Add a streaming stick, a soundbar and a switch and suddenly your coffee table is buried under remotes. This GE universal remote consolidates up to four devices into one familiar clicker, with auto-scan setup and pre-programmed codes for thousands of TVs, soundbars and streaming players.

A master volume button keeps audio control on whatever device runs your sound, and the layout is simple enough that anyone in the house can use it. It is the cheapest way to clean up the clutter that all these upgrades create.

If your TV lives far from the router, buffering and dropped 4K streams make even a new set feel broken. The TP-Link RE315 plugs into an outlet near the TV and rebroadcasts your Wi-Fi on both bands, with coverage up to 1600 square feet and support for up to 32 devices.

An Ethernet port lets you hard-wire the TV or streaming stick for the steadiest possible connection, and EasyMesh support means it cooperates nicely with compatible routers. Around thirty dollars buys the smooth, buffer-free streaming a five-year-old TV deserves.

Tired old HDMI cables can quietly throttle picture and sound, and a cheap one will not pass the high bandwidth that modern consoles and 4K HDR sources push. This certified UGREEN HDMI 2.1 cable handles the full 48Gbps, with 4K at up to 120Hz, eARC for lossless audio to a soundbar, and Dolby Vision and dynamic HDR.

If your TV supports higher refresh rates, this is the inexpensive link that actually lets you use them, and the braided build holds up to repeated plugging. At about thirteen dollars it is cheap insurance that your other upgrades reach the screen intact.
