Isn’t HDMI limited to 60 Hz?

@@ -4480,7 +4483,7 @@ 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.

- 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 adapter (up to 120 Hz at 1080p). A DisplayPort to HDMI Type 1 adapter will be limited to HDMI 1.0 speeds (60 Hz at 1080p).

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.
