Refresh Rate and HDMI 1.4b
Now that we’ve covered the basics of HDMI 1.4b, let’s talk about refresh rate and how it relates to this standard. Refresh rate, measured in Hertz (Hz), refers to the number of times a display updates the image on the screen per second. A higher refresh rate generally results in smoother and more responsive visuals.
HDMI 1.4b supports a maximum refresh rate of 120Hz at a resolution of 1080p (1920×1080 pixels). However, this doesn’t necessarily mean that it can’t support higher refresh rates at lower resolutions. In fact, some devices may be able to support 165Hz at a lower resolution, such as 720p (1280×720 pixels).
Does HDMI 1.4b Support 165Hz?
So, does HDMI 1.4b support 165Hz? The answer is a bit complicated. While HDMI 1.4b doesn’t officially support 165Hz at a resolution of 1080p or higher, some devices may be able to achieve this refresh rate at lower resolutions.
In general, it’s unlikely that a device with an HDMI 1.4b port will be able to support 165Hz at a resolution of 1080p or higher. However, if you’re looking to use a lower resolution, such as 720p, you may be able to achieve a higher refresh rate.
It’s also worth noting that some devices may use a technology called “overclocking” to achieve higher refresh rates than the official specification. Overclocking involves increasing the clock speed of the device’s graphics processing unit (GPU) to achieve higher performance. However, this can also increase the risk of overheating, instability, and other issues.

- HDMI 2.0: Released in 2013, HDMI 2.0 offers several key improvements over HDMI 1.4b, including increased bandwidth and support for higher refresh rates. HDMI 2.0 can support up to 240Hz at a resolution of 1080p, and up to 144Hz at a resolution of 1440p (2560×1440 pixels).
- DisplayPort 1.4: DisplayPort is a digital video interface standard that’s similar to HDMI. DisplayPort 1.4, released in 2016, offers several key improvements over HDMI 1.4b, including increased bandwidth and support for higher refresh rates. DisplayPort 1.4 can support up to 240Hz at a resolution of 1080p, and up to 144Hz at a resolution of 1440p.
Conclusion
In conclusion, while HDMI 1.4b doesn’t officially support 165Hz at a resolution of 1080p or higher, some devices may be able to achieve this refresh rate at lower resolutions. However, if you’re looking for a display technology that can support higher refresh rates, you may want to consider alternatives to HDMI 1.4b, such as HDMI 2.0 or DisplayPort 1.4.
When shopping for a display or device, be sure to check the specifications to ensure that it meets your needs. Look for devices that support higher refresh rates, and consider the type of content you’ll be viewing. If you’re a gamer or video editor, you may want to prioritize devices with higher refresh rates and faster response times.
