- No. Although this is not theoretically impossible, it is practically impossible at the moment, as there are no adapters (at the time of writing) from DVI or HDMI to DisplayPort that are capable of 120 Hz. DVI/HDMI to DisplayPort adapters are uncommon and unreliable even for standard 60 Hz video.
+ Yes. An
HDMI to DisplayPort active adapter is required. Please note this is
NOT the same as a
DisplayPort to HDMI adapter. Standard DisplayPort to HDMI adapters are for connecting DisplayPort sources to HDMI displays, not for connecting to DisplayPort displays.
- Please note that the inexpensive DisplayPort to HDMI and DisplayPort to DVI adapters and cables that can be commonly found will only function from a DisplayPort source to a DVI/HDMI display. They cannot be used to connect a DVI/HDMI source to a DisplayPort display. A much more expensive converter device is required for this, and I do not know of any that support >60 Hz video.
+ I have tested this adapter to work up to a maximum of 1920 × 1080 @ 120 Hz:

+ HDMI 1.4 or above is sufficient. HDMI 2.0 support is not required.
+
+ I tested this adapter with an AOC G2460PF and a ViewSonic XG2401, using a Radeon RX 480 and a GeForce GTX 1080. Please note that active adapters tend to be unreliable, and I cannot guarantee the adapter will work on any system.

+ For DVI outputs, there are no DVI to DisplayPort adapters capable of 120+ Hz.
- 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.

- 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 outputs. 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.
+ 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 outputs, or want to set up multiple monitors but don't have enough DVI ports. 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 has a maximum of 60 Hz at 1080p. A
Dual-Link DVI connection is required for 1080p 120+ Hz.
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.
- 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.

- 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.

+ However, at 144 Hz I did experience loss of signal when turning the monitor off and then on again, or putting the computer to sleep and waking it up again. I did not experience any issues when running at 1080p 120 Hz instead though.

+ As always, active adapters tend to be very finicky and I cannot guarantee that the adapter will behave the same on your system. My testing was done with an AOC G2460PF and a Radeon RX 480 and GeForce GTX 1080.
