Displayport 1.2 specs

DisplayPort 1-1.1a is able to output 144Hz at 1080p, while 1.2-1.2a can output 1440p at 144Hz, 1.3 outputs up to 120Hz at 4K, and 1.4 can output 144Hz at 4K using Display Stream Compression (DSC).

Is DisplayPort 1.2 enough for 4K?

DisplayPort 1.2 has support for only 8 audio channels and delivers 21.6 Gbps bandwidth and 17.28 Gbps data rates. Apart from that, the DisplayPort 1.2 only has support for up to 4K@120Hz resolution, while the DisplayPort 1.4 even supports max resolution up to 8K@60Hz with 10-bit color and HDR.

What is a 1.2 DisplayPort?

Today's most common version (for video wall displays), DisplayPort 1.2, supports video resolutions of up to 3840 x 2160 pixels, at a refresh rate of 60 Hz. The official name for this resolution is by the way UHD, but the term 4K is often used as well.

Is DisplayPort 1.2 enough for 1440p?

Display port 1.2 is the the best all around minimum for 1440p at 144Hz. 1.4 is much better. As for HDMI, the 2.0 version can do 4k at 60Hz and 1440p at 144Hz, as well as 1920x1080 240Hz. I think that is also a good option for you.

Can DisplayPort 1.2 do 165Hz?

Yes, DisplayPort versions 1.2 through 2.0 natively support 165Hz. So DP cables that correspond to these DisplayPort versions will give you 165Hz while the newer versions— that's DP 1.3, 1.4, and 2.0—go as high as 165Hz 4K and 240Hz 5K.

Does DisplayPort 1.2 support 240Hz?

DP 1.2 (a standard from 2010) is enough for even 1080p 240Hz.

Can DP 1.2 do 4K 60Hz?

DisplayPort 1.2: Supports up to 4K at 60Hz, some 1.2a ports may also support AMD's FreeSync. DisplayPort 1.3: Supports up to 4K at 120Hz or 8K at 30Hz. DisplayPort 1.4: Supports up to 8K at 60Hz and HDR.

Can DisplayPort 1.2 do HDR?

Does HDR video work with DisplayPort 1.2 or 1.3? No. HDR video requires greater bandwidth than DisplayPort 1.2 or 1.3 can provide, and requires DisplayPort 1.4 or better.

Is DP better than HDMI?

DisplayPort cables can achieve a higher bandwidth than HDMI cables. If there's a higher bandwidth, the cable transmits more signals at the same time. This mainly has an advantage if you want to connect multiple monitors to your computer.

Can DisplayPort do 144Hz?

For 1080p 144Hz you will need DisplayPort, Dual-Link DVI, or HDMI 1.3 (or higher), while 1440p 144Hz requires either HDMI 2.0 or DisplayPort 1.2.

Is there a difference between DisplayPort 1.2 and 1.4 cables?

DisplayPort 1.2 offers a maximum total bandwidth of 21.6 Gbps over its four lanes and a maximum total data rate of 17.28 Gbps. In comparison, DisplayPort 1.4 has the same four-lane structure but expands the maximum total bandwidth to 32.40 Gbps, and the maximum total data rate to 25.92 Gbps.

Is HDMI enough for 144Hz?

Does HDMI support 144Hz? Yes, depending on the HDMI version, resolution, and bandwidth. All versions of HDMI from HDMI 1.3 onward right through to HDMI 2.1 provide enough raw bandwidth for 144Hz, provided sacrifices are made in color, chroma, compression, or resolution.

Can DisplayPort 1.2 do 1080p 144Hz?

DisplayPort 1.2 can output 1080p and 1440p resolutions at 144Hz, while DisplayPort 1.3 and 1.4 increased bandwidth to manage up to 240Hz at those same resolutions and up to 120Hz at 4K.

What cable do I need to run 165Hz?

You can get 165 Hz using a DisplayPort 1.2 or 1.2a cable, DisplayPort 1.3 cable, DisplayPort 1.4 cable, or DisplayPort 2.0 cable. DisplayPort 1.2 and 1.2a cables will output 1440p (2560 x 1440) at 165 Hz, and support 1080p at 240 Hz.

Can DP 1.2 do 1440p 170Hz?

Displayport 1.2/1.2a supports 17.28 Gbit/s (Data Rate), and 1440p 165Hz requires 16.3Gbit/s. It's enough to achieve 170Hz. However, it will not support 170Hz with HDR on, or even 165Hz. You can achieve 144 Hz with slightly higher timings with HDR on using 1.2.

Can HDMI run 165Hz?

HDMI 2.0 carries combinations like 1440p 165Hz with no issue, and for 1080p, frame rates of 240Hz are no problem. On PC, HDMI is secondary to DisplayPort, which offers significantly more bandwidth, with DP 1.4 not that far from HDMI 2.1 and capable of 4K 120Hz.

Does DisplayPort 1.2 support 3440x1440?

SOLVED: DP 1.2 to HDMI 2.0 3440x1440@60Hz The HDMI ports are still revision 1.4a so they cannot support 60Hz refresh rates at the monitor's native resolution, but DisplayPort will run at 3440x1440 at 60Hz without any issues, including audio support."

Is there a big difference between 144Hz and 165Hz?

The simple answer to that is no, not a big difference. Since 165fps is just 21 frames per second more than 144. That's just a 13% increase. Most people aren't likely to notice those extra frames, but the clincher is that if you're getting a new monitor for gaming, you should know that 165Hz is basically the new 144Hz.

Can DP 1.2 do 240Hz on 1080p?

DisplayPort has been at the forefront of high refresh rate gaming for years, with even DisplayPort 1.2 cables offering up to 240Hz at 1080p resolution and 144Hz at 1440p.

Should I use HDMI or DP for 240Hz?

HDMI tops out at 144Hz uncompressed or 240Hz compressed, while DP 1.4 can hit 360Hz in 1080p. If you're trying to pick a monitor, HDMI is the budget-friendly choice, but if you've got DP you'll have more options if you plan to upgrade to a new graphics card or add an external GPU in the near future.
