If you are shopping around for a new display, you may be looking to compare computer monitors with HDMI vs DVI ports and input connections. The best computer monitors, after all, tend to feature one or both of these port options, in addition to others. Keep reading to learn the differences between the two. If you’re a beginner to all these cable names, check out our guide to monitor ports.
The primary difference between the two connection types is, well, the connections themselves. DVI cables (digital visual interface) are considered the old standard, having existed HDMI cables became commonplace. Of course, both are currently being usurped by even newer connection types, such as USB-C. As for real-world differences, some will be subtle while others stark, such as when you are comparing glossy vs matte computer monitors.
Plus, HDMI and DVI are far apart from Thunderbolt 3, which is primarily used by Apple computers and devices.
Here are more differences between HDMI and DVI Cables
Make sure you know which ports your devices include before making a purchase of any cable, especially if the device is older. Most computer monitors in early 2000 used VGA, and there’s a vast difference between VGA vs HDMI in connectivity.
An obvious difference between the two is size. HDMI 2.0 cables are much more compact than DVI cables, allowing them to be used in a wider variety of gadgets, such as laptops and the like. It is rare to find a DVI port on a modern laptop due to its overall size. Of course, micro versions are available for both DVI and HDMI cables, but they may not offer universal compatibility.
HDMI 2.0 technology is newer and, as such, faster than DVI technology when it comes to digital signals. The latest version of HDMI (2.1) can support a maximum data rate of 42.6 Gbit/sec while DVI has a maximum data rate of 9.9 Gbit/sec. Additionally, this reduced data transfer speed with DVI cables could lower some crucial data metrics, if you are looking to compare the refresh rate vs the response time of a computer monitor.
The decreased data rate available with DVI cables when compared to HDMI 2.0 does mean the former will be hampered when it comes to ultra-high-definition visuals and their maximum resolutions. The maximum specs DVI can support is 3840×2400 at 30 Hz or 2560×1600 at 60 Hz.
One of the primary reasons HDMI caught on is that the technology is designed to deliver both audio and video signals at the same time via a single cable, eliminating the need for a dedicated audio cable. The same cannot be said, however, for DVI cables, as they cannot transport audio signals.
Is DVI to HDMI better than HDMI to HDMI?
Though you can convert DVI to HDMI via an adapter, going HDMI to HDMI will be the better choice when it comes to compatibility with a graphics card, high frame rates, and other metrics.
How do I know which DVI cable to buy?
There are not too many different types of DVI cables, so you should be fine with whatever one you choose for your display device. You should, however, make sure you are but buying a mini DVI for your gaming monitors and the like unless warranted.
Which port type is best for monitors?
This depends on your needs and what you are connecting them to. Some older devices may have VGA ports (video graphics array) for analog signals while others may have the older HDMI 1.4 standard.
STAT: DVI’s digital video transmission format is based on panelLink, a serial format developed by Silicon Image that utilizes a high-speed serial link called transition minimized differential signaling (TMDS). (source)
