Types of the VGA to HDMI Thunderbolt

A VGA to HDMI Thunderbolt cable is a type of video adapter. It connects a device with a VGA output, such as an older computer or laptop, to an HDMI monitor or TV. The Thunderbolt connection provides a way to do this when the Thunderbolt port is available. It converts the analog VGA signal to digital HDMI, allowing users to display video content on a high-definition screen. Commonly, these cables also include an audio adapter to transmit sound because VGA only carries video. It becomes beneficial for extending presentations, watching movies, or gaming on a larger HDMI-compatible display.

Understandably, most buyers will go for this kind of adapter when trying to connect an aging PC to a recently purchased 4K flat screen. The adapters do function well, but it must be noted that there are two popular types to be precise.

• Active VGA to HDMI Adapter: Ideally, this kind of adapter will have to be connected to a power source, like a USB port. Nothing serious, though—most people connect it to a spare USB port on the PC, which is no hassle at all. The adapters come with an instruction manual that informs users where to connect the USB power cable. These adapters are coveted because they convert the VGA signal, which is analog, to HDMI. They also have the extra feature of being able to output sound. Since the VGA is connected to an old PC that only supports analog signals, the sound cannot be transmitted through HDMI unless it is somehow embedded into the cable, which is hardly the case. So, the user will have to connect a 3.5mm audio cable from the PC to the HDMI monitor or TV. The problem with this scenario is that there are no inputs for the 3.5mm cable on the TV or monitor, so one will have to use a separate 3.5mm audio cable and connect it to a hifi system that will then play the sound. The music sound would, of course, be much better than any TV sound, so many people do prefer this connection.
• Passive VGA to HDMI Adapter: These adapters do not require a separate power supply. They are much easier to set up because they do not require connecting a USB power cable to a power source. The connection is straightforward, requiring only the cables with no connecting wires. However, it must be clear that passive adapters can only convert the VGA signal to HD1080p at the maximum and cannot embed audio into the HDMI cable. So, like in the previous scenario, the 3.5-mm audio cable must connect to the TV or monitor, which is obviously impossible in most cases. In that case, the audio will go to the TV or monitor, and the PC will then become the primary audio source. The sound coming out of the TV or monitor will be of much lower quality than that coming out of the PC. Essentially, the cable should only be purchased if it is really urgently necessary to have the PC image on a bigger screen. However, the PC does have an HDMI out, and it can, of course, be connected directly to the TV, but then no further connections can be made.

VGA to HDMI Thunderbolt Q&A

Q1. Can a Thunderbolt cable be used to connect a Thunderbolt laptop to a VGA display?

A1. Yes, if the Thunderbolt laptop has a VGA port, a Thunderbolt cable can connect them directly. If the Thunderbolt laptop only has a VGA, Thunderbolt to VGA cable can connect them. If the Thunderbolt laptop only has a USB port, a Thunderbolt to USB adapter can be used to connect them.

Q2. Does a Thunderbolt to VGA adapter work with VGA devices?

A2. Yes, a Thunderbolt to VGA adapter can be used to connect a Thunderbolt device to a VGA device like a monitor or projector. However, VGA is an analog signal and will not support the same resolutions and refresh rates as digital signals like HDMI or DisplayPort. The video quality may be lower, and features like audio and device controls cannot be transmitted through a VGA connection.

Q3. What are the limitations of using a Thunderbolt to VGA adapter?

A3. Some limitations are listed: 1. Audio support – VGA cables do not carry audio signals, so separate cables are needed to connect to speakers or sound systems. 2. Resolution and refresh rate – Since VGA is an analog interface, it cannot achieve the same high resolutions and refresh rates as digital connections like HDMI or DisplayPort. 3. Device controls – Features like turning devices on and off with the cable, muting audio, or selecting different inputs are not supported by VGA. 4. Lack of copy protection – Analog interfaces like VGA do not support copy protection standards like HDCP, so viewing encrypted content may have limitations.

Q4. Does a VGA cable work with an HDMI port?

A4. No, a VGA cable cannot be connected directly to an HDMI port. Since both cables use different connections, they do not work together. To connect a device with only VGA output to a device that only has an HDMI input, the VGA signal needs to be converted to HDMI using a converter. If trying to connect a VGA cable from a computer to an HDMI TV, for example, the TV will not display anything because the TV's HDMI input does not accept the VGA signal from the TV. A conversion box would be required to change the signal from VGA to HDMI.

Q5. Does a Thunderbolt to VGA adapter support dual displays?

A5. It depends on the adapter and the computer being used. Some Thunderbolt to VGA adapters allow connecting two VGA monitors from one Thunderbolt port on the computer using a dual VGA output adapter. However, the computer must support extended desktop mode for multiple displays, and the graphics card needs to be capable of outputting two separate video signals at the same time. Compatibility will vary based on the type of Thunderbolt port (Thunderbolt 1, 2, 3, or 4) and the operating system (Windows or MacOS). It's best to check the specifications of the adapter and computer to see if dual display connections are supported.
