Identify the Ports on Your Old Device
Flip the device around and look at its back panel. DVD players, VCRs, and older game consoles typically have one of three output types: composite video (a single yellow RCA jack plus red and white audio jacks), component video (five jacks, three for video in red, green, and blue plus two for audio), or coaxial RF (a round threaded connector that cables screw onto). Some older cable boxes and satellite receivers add S-Video, which is a small round multi-pin connector. Write down or photograph what you see before shopping for anything.
Identify the Inputs on Your New TV
New TVs sold in the last several years drop most legacy inputs in favor of HDMI. Count the HDMI ports on the back and side of your TV, since many sets have two to four. A few budget TVs include a single composite input labeled AV or a 3.5mm multi-purpose jack with a bundled breakout cable, but that is increasingly rare. If your TV has no matching input for your old device, a converter is the only option short of replacing the device.
Composite or Component to HDMI
A composite-to-HDMI converter takes the yellow, red, and white RCA plugs from your DVD player or VCR and converts them to a single HDMI output. The Warrky WARRKY-AV-H02 is priced at $13.89, carries a 4.4-star rating across 2,000 reviews, and has 2 HDMI outputs, so it handles both a small display and a receiver simultaneously. Component-to-HDMI converters work similarly but accept the five-cable setup and produce a slightly sharper picture since component carries a better signal than composite. These converter boxes typically require a USB power cable for the converter itself, so make sure a USB port or standard adapter is nearby.
Coaxial RF to HDMI
Older cable boxes, antennas, and VCRs often output via a coaxial RF cable that screws into a round port. Your new TV may still have one coaxial input, usually labeled ANT or RF IN, so try that first. If yours does not, or if you want the video on an HDMI input, you need an RF modulator or a converter that accepts coaxial in and outputs HDMI. The Antronix CMC2002H-A is a straightforward coaxial splitter rated 4.5 stars across 558 reviews at $5.95, useful when you are routing an antenna signal to two rooms rather than converting formats. For actual format conversion from RF to HDMI, look for a box specifically labeled RF to HDMI.
When You Have More Devices Than HDMI Ports
If you have a DVD player, a game console, and a streaming box but your TV only has two HDMI ports, an HDMI splitter is not what you need. You need an HDMI switch, which lets multiple sources share one input. If you do want to send one source to multiple displays at the same time, that is when a splitter applies. The Orei UHDS-104 is one of the most popular options in this category, rated 4.4 stars across 5,400 reviews and priced at $33.95, with 4 HDMI ports and 4,000 units bought in the last month. It handles up to 4K and is a practical pick if you want to duplicate a signal to several screens.
Audio Considerations
Many converter boxes pass stereo audio through the HDMI output automatically, so you do not need a separate audio cable. However, some budget composite-to-HDMI boxes strip multichannel audio to stereo, which matters if your old DVD player outputs Dolby 5.1 via a digital optical or coaxial audio output. In that case, run the video through the converter and the audio separately from the device's optical out to your soundbar or receiver. If your soundbar has limited inputs, a Toslink optical splitter lets you share one optical source between two devices, so both get the signal without unplugging anything.
Common mistakes to avoid
- Buying an HDMI splitter when you need an HDMI switch. A splitter copies one source to many screens. A switch selects among many sources for one screen. These are not interchangeable.
- Plugging a composite-to-HDMI adapter into the wrong direction. These converters are one-way. Composite in, HDMI out. You cannot use the same box to go HDMI to composite.
- Skipping the power cable. Most composite-to-HDMI converters need USB power to operate. Plugging them in but forgetting the power supply produces a black screen.
- Confusing component video with composite video. Component uses five cables (three for video, two for audio) and produces a much cleaner picture. Composite uses three cables (yellow, red, white). They need different converters.
- Assuming the TV's coaxial port accepts cable box output at full quality. The RF coaxial input on modern TVs is for antennas only. A cable box connected via coaxial will produce a standard-definition picture at channel 3 or 4, not a quality HD signal.
- Using a cheap passive adapter instead of an active converter. A passive HDMI-to-RCA plug with no electronics inside does not work. Proper video conversion requires active circuitry inside the converter box.
Frequently asked questions
Can I connect a VCR to a new TV that has no composite input?
Yes, with a composite-to-HDMI converter. You plug the yellow, red, and white RCA cables from the VCR into the converter, then run an HDMI cable from the converter to any HDMI port on your TV. You will also need to power the converter with a USB cable. The picture quality will be limited by the VCR's original output, not the converter.
Will connecting an old device through a converter reduce picture quality?
The converter will not degrade quality below what the old device is already producing. A DVD player outputs 480p at best, and that is what you will see on screen regardless of how good the converter is. A good converter simply passes the signal cleanly without adding noise or color errors. The picture may look soft on a large 4K panel because the source itself is standard definition.
Do I need a powered HDMI splitter or will a passive one work?
For most home setups with two screens, an active powered splitter is the safer choice. Passive splitters divide the signal electrically and can cause handshake failures or dim pictures, particularly at 4K. Active splitters amplify and re-clock the signal so each output gets a full-strength copy. The difference in price is usually $10 to $20 and is generally worth it.
My old game console has component output. Can I use it on a new TV?
If your TV has no component input, you need a component-to-HDMI converter. These are widely available for $15 to $30. The component signal carries much better color and resolution than composite, so older consoles that support 480p or 1080i via component will look noticeably sharper than they would through a composite connection.
