Does DVI support 4k?


You must be familiar with the several connections available that connect a computer to any monitor. Today, digital connections rule the world with many options like HDMI, DisplayPort, and many others. Whichever connection you choose, the quality of the output mustn’t be compromised.

Being comparatively older, many still stick to DVI, short for Digital Video Interface. But the question is whether it is compatible with your devices. DVI is better suited if you want to get the most out of your high frame rate on a 1080p monitor.

Quick answer: 4K video cannot be outputted from the DVI port due to the limitation of resolution which is a maximum of 2560 x 1600. To get 4K resolution, you will be need to use HDMI or use the DisplayPort ports. Not all HDMI or DisplayPort can output 4K. Always check the maximum resolution the port can support. Read more

What is DVI?

DVI is a video display interface capable of transmitting digital video to monitors that have resolutions of up to 2560 x 1600. Display devices like projectors and computer screens use DVI connections. The only drawback with DVI is that it transmits only video and not audio signals. This makes it less popular for TVs where HDMI is preferred.

DVI can support both digital and analog signals, and depending on which signals they carry, they can be of three types: DVI-A, DVI-D, and DVI-I. DVI-A supports only analog signals, DVI-D supports only digital signals, and DVI-I supports both.  

DVI and 4K

Most graphics card available today supports DVI, although many other connections have come to replace it effectively. The main factor differentiating DVI from HDMI is that DVI does not support audio. But this issue has a solution in the latest graphics cards where you can use a DVI to HDMI adapter or cable to make audio transmission possible.

Single link DVI only supports a resolution of 1,920×1,200 only, while the resolution value for a dual-link DVI is 2560×1600. Users working with a 1080p 144Hz monitor can consider going for DVI as it offers a refresh rate of 144Hz. This can be very helpful for gamers who prefer frame rates higher than 60 for a better gaming experience.

Unfortunately, DVI does not support 4K resolution. 4K is only possible with connections like HDMI and DisplayPort. Some of the newer standards even support 5K displays. Note that DVI can be adapted to VGA using a passive adapter.

What connections support 4K?

HDMI and DisplayPort are two connections that commonly support 4K resolutions and even 5K for newer devices. Linking your TV to your PC is best done with HDMI as it carries audio too. If the TV has HDMI 1.4, you can have 4K at 30Hz. But if you have a 4K display and a video card, you can achieve even 4K at 60Hz.

While the older DisplayPort 1.2 supports 4K at 60Hz or 1080p resolution at 144Hz, the newest standard DisplayPort 1.3 enables 8K at 60Hz or 4K at 120Hz.  

If what you own is a DVI device and want to connect it to other devices that are not compatible with DVI, a cable or an adapter can come to your aid. More specifically, 4K at 60Hz can be achieved by two dual-link DVI cables. 

Q&A

Is DVI better than HDMI for 4K?

HDMI is the best choice if you are just connecting a gaming console, blu-ray player or streaming device to your TV. DVI is a good choice if you’re looking to get the most out your high frame rate on a 1080p monitor. With the latest graphics cards, gaming at 4K resolution and a 120Hz refresh rate is possible.

Can DVI do 4K 60 Hz?

A single dual-link DVI connection can deliver up to 2560 × 1600 at 60 Hz. Achieving 4K at 60Hz requires two dual-link DVI cables, or DisplayPort 1.2 or HDMI 2.0. So, yes, as you put it, that’s a limitation of DVI.

What is the highest resolution DVI supports?

Can DVI do 1440p?

DVI-D can handle 1440p@120hz, but is dependant on the cable, the connectors and the GPU. 1440p@60hz should be non-issue. HDMI cables that can handle 4k@30hz should be able to handle 1440p@60hz.

Does DisplayPort 1.2 support 4K 60Hz?

Is DVI capable of 1080P?

While DVI doesn’t have as extensive support for ultra-high definition resolutions as DisplayPort and HDMI do, it can handle 1080P gaming just fine. And, even if you want to game on a 1080P 144Hz monitor, all three of these interfaces will work.

Do graphics cards still use DVI?

Since the vast majority of people still use 1080p monitors (Both 60 and 144Hz) DVI is still around. VGA barely just got killed off and DVI may start seeing the same fate soon enough(See the 1080Ti), especially when 1440p+ monitors start becoming the norm.

What does DVI stand for?

DVI stands for “digital visual interface“. DVI cables are most commonly used to transmit video data from older PCs to older monitors (HDMI cables are a more advanced replacement that transmit audio data as well as video, unlike DVI cables).
