How to Check HDMI Port on Laptop?

There are several ways on how to check HDMI port on laptop and it all involves taking a look at the specsheet.

The specsheet of a laptop can not only tell you the version of the HDMI port, but can also detail its supported specifications.

You can access the specsheet of your laptop by heading over to the manufacturer’s website or by having a look at the manual provided with it.

If you do not have the manual and cannot access the specsheet online, then trial and error is the only way to test.

In the following text, I will talk in detail about how to check what kind of HDMI port you have on your laptop.

Understanding the Versions and Specs HDMI

Before you try to understand what HDMI port you have on your laptop, it is worth understanding the different HDMI port version that exist today.

HDMI is an ever evolving interface. As the demand of resolution and refresh rate increases for monitors and screens, so does the demand for newer and more robust HDMI standard.

Hence, the different HDMI versions are particularly differentiated by the maximum resolution and refresh rate they can carry.

For instance, the most common HDMI version, HDMI 1.4, found on laptops and PCs, can only show upto 4K resolution at 30Hz refresh rate.

If you want to connect to a 4K monitor and have 60Hz refresh rate, you will at least need an HDMI 2.0 port. The following table explains this further:

How to Check HDMI Port on Laptop?

There are few things that you want to check.

  1. HDMI Port Version
  2. Whether it is Input or Output
  3. Type of HDMI Port (Form Factor)

The most important of these consideration is generally knowing the HDMI port version.

How to Check HDMI Port Version on Laptop?

You can check the HDMI port version on your laptop through two methods:

  1. Reading the Specsheet
  2. Trial and Error

1. Checking HDMI Port Version Through Laptop’s Specsheet

By accessing the technical specsheet on the manufacturer’s official website or through the manual provided, you can definitively figure out what version of HDMI port your laptop has.

For instance, you can clearly see that ASUS TUF Gaming F15 has an HDMI 2.0b port according to its specsheet. Hence it can support an external display with upto 4K@60Hz.

Sometimes the specsheet does not tell you the HDMI port version but instead only list the specs the HDMI port supports.

Take for instance, the following MSI GL66 Pulse Gaming laptop. The specsheet for this laptop does not tell you what version the HDMI port conforms to.

Instead it tells you that the port supports 4K @ 60Hz. From this we can infer that it has an HDMI 2.0 port.

2. Checking HDMI Port Version Through Trial and Error

Another method on how to check the HDMI port version on your laptop is through trial and error.

You will need to have a 4K monitor in order to test your HDMI port out.

Plug in your monitor to the HDMI port on your laptop. Make sure you are using an HDMI 2.0 cable (Premium High Speed HDMI cable at least).

If the monitor runs at 4K@60Hz, then you have an HDMI 2.0 port. If it runs at 4K@30Hz, then you have an HDMI 1.4 port.

Similarly to test if you have an HDMI 2.1 port, you will need to have at least a 4K monitor with a refresh rate higher than 60Hz, i.e 100Hz, 120Hz, 144Hz etc.

Again, to check if you have an HDMI 2.0 or an HDMI 2.1 port, you will need to use Premium High Speed or Ultra High Speed HDMI cable.

How to Check if HDMI is Input or Output on Laptop?

Laptop is a source device just like a desktop, gaming console, Blu-Ray player or a Set-top Box is.

Hence, it SENDS audio/video signals to the display device such as the monitors, TVs or projectors.

As such, the HDMI port on a laptop is almost always an HDMI OUTPUT port, unless otherwise specified in the specsheet.

Since laptops have an HDMI output port, the laptop’s display cannot be used as an external monitor.

People often assume that they can connect multimedia devices like a gaming console, set-top box to a laptop’s HDMI port and play them on the laptop’s screen, however, that is simply not possible.

Display devices have HDMI input ports. Laptops only have an HDMI output port.

The majority of the laptops have the Standard Type-A HDMI port.

However, if you have an ultra portable laptop then you may have a mini or micro HDMI port. This is actually quite rare and unless you have a very old ultrabook, then chances are you have the Standard HDMI Type-A port on your laptop.

Final Words

In this short guide, I talked about how you can check HDMI port on laptop. The short and simple way to check is through the specsheet.

However, you will need to know the jargon involved in order to understand what the specs in the datasheet mean.
