+ DisplayPort does not have different types of cable certifications. There are no cable versions, no certification tiers, and no official bandwidth categories. Although there are multiple versions of the DisplayPort video standard, all versions use the same cable. Every feature of every version of DisplayPort works on any spec-compliant cable.

Please refer to the DisplayPort website

Please note that this does not mean "any DisplayPort cable you buy is as good as any other". It is possible to manufacture a cable that cannot handle higher data rates like 4K 60 Hz. Such a cable would be non-compliant with the DisplayPort specification's cable requirements, but this does not stop the cable from being sold to consumers. Many DisplayPort cables on the market have not been certified by VESA (the creators of the DisplayPort standard), and therefore are not guaranteed to handle the full bandwidth of the latest DisplayPort version. It is advised to purchase cables which are certified by VESA. The official list of certified cables may be found
here (unfortunately it is not a large list).
Since many people seem to be having trouble finding quality DisplayPort cables, here are some recommendations:

- It is not possible to connect VGA output to HDMI input with a passive adapter.
+ It is not possible to connect VGA output to HDMI input with a passive adapter. It is also not possible to create a chain of passive adapters from VGA → DVI → HDMI. VGA to DVI passive adapters do not convert your VGA signals into DVI signals, they do not actually do anything, they just pass the same VGA signal through. They will only work when connected to special DVI + VGA combo ports called DVI-I, which can accept VGA signals in addition to DVI signals. These adapters will not work for connecting to standard DVI-D ports (which only accept DVI signals) or for sending signals through a DVI to HDMI adapter (which also require DVI signals).
+
+ The only purpose of a VGA to DVI passive adapter is to physically change the shape of the port from VGA-shape to DVI-shape, so that it can be connected to a DVI-I port. It does not convert the electrical signals, they are still VGA signals the whole way through.

These HDMI to
Single-Link DVI passive adapters
may work for 120+ Hz if used from a DVI
output (computer/source) to an HDMI
input (display) because it acts as an HDMI connection when used in this configuration, and HDMI 1.3+ can support 1080p 120 Hz as mentioned previously, but this does require the monitor to accept 120+ Hz over HDMI, so it will not work on monitors like the BenQ XL2411Z or ASUS VG248QE, which are limited to 60 Hz on their HDMI ports.
-
Connecting to the display's HDMI input
+ Some 1080p 144 Hz displays, such as the BenQ/Zowie XL2411Z and Acer GN246HL, only have DVI and HDMI inputs, they do not have DisplayPort. Furthermore, the HDMI ports on these monitors are limited to 60 Hz, which means that
Dual-Link DVI
must be used in order to reach 144 Hz on these monitors.
- HDMI 1.3 and 1.4 can support up to 144 Hz at 1080p, but this will not work on all monitors. Some monitors such as the BenQ-Zowie XL2411(Z), the ASUS VG248QE, and the Acer GN246HL will not accept >60 Hz over HDMI even though they have HDMI 1.4a inputs. This is not because "HDMI is limited to 60 Hz" (it isn't), this is just a limitation of these particular products.
+ This can be problematic for people that want to use these monitors with laptops, or with newer graphics cards that don't have native DVI ouptuts. HDMI-to-DVI and DisplayPort-to-DVI passive adapters will
not work, because HDMI and DisplayPort only support passive adapters to
Single-Link DVI, which only supports 1080p 60 Hz. A
Dual-Link DVI connection is required for 1080p 144 Hz.
- On monitors that
do accept >60 Hz over HDMI (such as the ViewSonic XG2401), you can use either a straight HDMI connection, a DVI to HDMI adapter, or a DisplayPort to HDMI Type 2 passive adapter (up to 120 Hz at 1080p). A DisplayPort to HDMI Type 1 passive adapter will be limited to HDMI 1.2 speeds (60 Hz at 1080p).
+ Please also note that many HDMI-to-DVI and DisplayPort-to-DVI passive adapters will be disguised and falsely advertised as "
Dual-Link DVI" adapters, so if you think you've found one, you haven't. HDMI and DisplayPort
do not support passive adapters to
Dual-Link DVI, they are
all Single-Link DVI adapters no matter what they say or what they look like.
-
Connecting to the display's DVI input
-
Single-Link DVI only supports up to 60 Hz at 1080p, so
Dual-Link DVI is required for 120+ Hz. This means inexpensive DisplayPort-to-DVI or HDMI-to-DVI passive adapters / cables cannot be used, because DisplayPort and HDMI only support passive adapters to
Single-Link DVI, not to
Dual-Link.
Almost all DisplayPort-to-DVI and HDMI-to-DVI cables / adapters have fake "Dual-Link" connectors on them, but don't be fooled; they are still Single-Link DVI adapters in disguise. DisplayPort and HDMI do not support passive adapters to Dual-Link DVI; it is physically impossible to create such an adapter due to an insufficient number of pins on the DP and HDMI connectors.
+ If your computer does not have a
native Dual-Link DVI output, then the only other way of getting a
Dual-Link DVI connection is with a DisplayPort to
Dual-Link DVI active adapter, which usually costs around $100 and are generally not very reliable. Also note that not just any DP-to-DVI active adapter will work, it must be a
Dual-Link active adapter. There are active adapters which only support
Single-Link DVI, intended for multi-monitor configurations on some older AMD graphics cards (detailed
here), and these adapters will not work for 1080p 120+ Hz.
- If you are using a monitor that only has DVI and HDMI inputs (no DisplayPort) and also doesn't accept >60 Hz over HDMI (like the BenQ XL2411Z), then you
must use the
Dual-Link DVI input. If your computer does not have a native DVI output to connect to it, you
must use a DisplayPort to
Dual-Link DVI
active adapter.
+ DisplayPort to
Dual-Link DVI active adapters are expensive and unreliable, and should only be used as a last resort if you have no other method of connecting. If you have not purchased your monitor yet I suggest you do not buy the XL2411Z or GN246HL, but instead get a monitor that has DisplayPort input instead. The cost of a DP-to-DL-DVI adapters is greater than the price difference for purchasing a monitor that has a DisplayPort input to begin with.
-
Not just any DisplayPort to DVI active adapter will work. There are plenty of DisplayPort to
Single-Link DVI active adapters, intended for multi-monitor configurations on some older AMD graphics cards (detailed
here). Inexpensive DisplayPort to DVI active adapters are all
Single-Link-only and will not work for 1080p 120+ Hz. True DP to
DL-DVI active adapters are very expensive, and generally quite unreliable. They should only be used as a last resort. If you haven't purchased your monitor yet, don't buy one that only has HDMI and DVI. Look for one that has native DisplayPort input instead.
