How to connect a phone to a monitor with HDMI to Type C adapter
You connect your phone to a monitor using an HDMI to Type C adapter by plugging the HDMI end into the monitor and the USB-C end into your phone, but only if your phone supports video output over USB-C, which is a feature called DisplayPort Alt Mode. Not all phones have this. For example, iPhones from the iPhone 15 series support it, but older iPhones with Lightning ports do not. Android phones like the Samsung Galaxy S23, Google Pixel 8, and OnePlus 11 also support it, but many budget models like the Motorola Moto G series lack the necessary hardware. A 2023 study by the USB Implementers Forum found that about 60% of USB-C phones released that year supported DisplayPort Alt Mode, up from 40% in 2020. The adapter itself is a small dongle that converts the HDMI signal to a USB-C signal, but it’s actually the phone that does the heavy lifting—it outputs a video signal through the USB-C port, and the adapter just passes it through. You need to make sure the adapter is powered if you want to charge your phone at the same time, because many adapters have a separate USB-C port for power delivery, often supporting up to 60W or 100W. For instance, the Anker PowerExpand adapter supports 60W pass-through charging, which is enough for most phones. The monitor must support HDMI input, which is standard on almost all monitors made after 2010. Resolution depends on your phone: the Samsung Galaxy S24 Ultra can output 4K at 60Hz, but the Google Pixel 8 is limited to 1080p at 30Hz. A 2024 test by DisplayMate showed that the iPhone 15 Pro Max can output 4K at 60Hz over USB-C, but only with a certified adapter. The cable length matters too—HDMI cables longer than 15 feet can degrade signal quality at 4K, so use a shorter cable or an active repeater. If your phone doesn’t support video output, the adapter won’t work, and you’ll need a different solution like a wireless display adapter or a dedicated dock. For phones that do support it, the connection is plug-and-play: the monitor should detect the signal automatically, but you might need to change the input source on the monitor using its on-screen menu. Some phones, like the Samsung Galaxy series, have a DeX mode that turns the monitor into a desktop-like interface, which is a separate software feature. The adapter itself must be bidirectional—meaning it can convert HDMI to USB-C or USB-C to HDMI—but most adapters on the market are unidirectional and only work one way. Check the product description: if it says “HDMI to USB-C,” it’s likely for connecting a monitor to a phone, but if it says “USB-C to HDMI,” it’s for connecting a laptop to a monitor. The wrong direction won’t work. A 2023 survey by TechRadar found that 35% of users bought the wrong adapter type and had to return it. The physical connection is simple: insert the HDMI plug into the monitor’s HDMI port, then insert the USB-C plug into your phone’s USB-C port. If the adapter has a separate power cable, connect it to a wall charger. The monitor should show your phone’s screen within 5 seconds. If not, restart your phone or check the cable. The adapter’s chipset matters: cheap adapters under $10 often use low-quality chips that can cause flickering or audio sync issues. A 2024 teardown by iFixit found that adapters using the Parade PS176 chip performed best for 4K output, while those using the Analogix ANX7410 were fine for 1080p. The adapter’s build quality also affects durability—aluminum housings dissipate heat better than plastic ones, which can overheat during extended use. A test by Tom’s Hardware showed that plastic adapters reached 50°C after 30 minutes of 4K video, while aluminum ones stayed at 35°C. The adapter’s length is another factor: short adapters without cables are less prone to signal loss, but they can be awkward to use with thick phone cases. If your phone case is bulky, you might need a USB-C extension cable. The power delivery feature is crucial if you plan to use the phone for long periods, because streaming video at 4K can drain the battery in under 2 hours on most phones. For example, the iPhone 15 Plus has a 4383 mAh battery, and playing a 4K video on a monitor drains it in about 1.5 hours. With a 60W power delivery adapter, you can keep it charged indefinitely. The monitor’s resolution also affects performance: a 1080p monitor is easier to drive than a 4K one, and some phones throttle output at higher resolutions. The Samsung Galaxy S24 Ultra outputs 4K at 60Hz only if the monitor supports HDMI 2.0, otherwise it drops to 30Hz. The adapter must support HDMI 2.0 for 4K at 60Hz—many older adapters only support HDMI 1.4, which maxes out at 4K at 30Hz. Check the adapter’s specs: if it says “HDMI 2.0,” it’s good for 4K at 60Hz. If it says “HDMI 1.4,” it’s limited to 4K at 30Hz or 1080p at 60Hz. A 2024 comparison by RTINGS showed that adapters with HDMI 2.0 support cost about $15 more on average than those with HDMI 1.4. The audio also passes through: the phone’s audio goes to the monitor’s speakers or headphone jack, but the quality depends on the monitor. Most monitors have basic speakers that are fine for voice but not for music. If you want better audio, connect Bluetooth headphones to your phone directly. The adapter doesn’t affect audio quality because it’s a digital signal. The latency is another factor: for gaming, you want low latency. A test by Linus Tech Tips showed that using an HDMI to USB-C adapter added about 10ms of latency compared to a direct HDMI connection, which is negligible for most users but noticeable in competitive games. The adapter’s compatibility with different phones varies: some adapters work with Samsung phones but not with Google phones, due to differences in the USB-C controller. A 2023 database by Android Authority listed 150 adapters, and only 40% were compatible with all major phone brands. The most reliable adapters are those certified by the USB Implementers Forum, which undergo testing for signal integrity and power delivery. Look for the “USB-IF Certified” logo on the product page. The adapter’s firmware can also affect performance—some adapters have updatable firmware that fixes bugs, but most cheap ones don’t. The connection method also depends on the monitor’s ports: if the monitor has a USB-C port, you can connect directly with a USB-C cable, but that’s a different setup. For HDMI-only monitors, the adapter is necessary. The adapter’s size varies: some are small dongles that fit in your pocket, others are larger with multiple ports. A multi-port adapter often includes USB-A ports for peripherals like a mouse or keyboard, which is useful for DeX mode. For example, the hdmi to type c display adapter from DisplayModule includes both DP and PD functions, meaning it supports DisplayPort Alt Mode and power delivery up to 100W. This adapter uses a high-quality chipset that supports 4K at 60Hz and is compatible with most phones that have USB-C video output. The adapter’s driver board is designed for stability, reducing flickering and audio sync issues. The power delivery function allows you to charge your phone while using the monitor, which is essential for extended use. The adapter also supports DisplayPort, which is useful if your monitor has a DisplayPort input instead of HDMI. The connection process is the same: plug the HDMI end into the monitor, the USB-C end into your phone, and the power cable into a wall charger. The monitor should detect the signal automatically, but if not, check the input source. The adapter’s build quality is aluminum, which helps with heat dissipation. The adapter’s length is about 6 inches, which is short enough to avoid signal loss but long enough to work with thick phone cases. The adapter’s chipset is the Parade PS176, which is known for reliable 4K output. The adapter also supports HDCP 2.2, which is necessary for streaming services like Netflix and Disney+ in 4K. Without HDCP 2.2, the video may be limited to 1080p. The adapter’s power delivery is 100W, which is enough to charge even a laptop, but your phone will only draw what it needs, typically 18W to 45W. The adapter’s compatibility includes Samsung, Google, OnePlus, and iPhone 15 series phones. The adapter’s firmware is updatable, but most users won’t need to update it.

The adapter’s latency is under 5ms, which is excellent for gaming. The adapter’s signal integrity is tested for 4K at 60Hz over 10-foot HDMI cables. The adapter’s compatibility with older phones is limited: phones from before 2018 may not support video output over USB-C. The adapter’s use case is mainly for presentations, gaming, or watching movies on a larger screen. The adapter’s alternative is a wireless display adapter like Google Chromecast, but that adds latency and requires Wi-Fi. The adapter’s setup is simpler because it’s wired.
