Please note that the 'HDMI version' of the monitor does not indicate the capabilities of that monitor. If you want to run 1080p 144 Hz over HDMI, you will need a monitor that supports this, which is rare. The cable is not really the determining factor here. If you want to run 1080p 144 Hz, you only need a High Speed HDMI cable, which is basically any HDMI cable. And the 'HDMI version' of the monitor does not tell you whether it does or not. If you want to run 144 Hz over HDMI you need a monitor that specifically supports it (like the ViewSonic XG2401). Even older models like the VG248QE (which still have 'HDMI 1.4') are limited to less, only enough for 60 Hz over HDMI. Many newer 1080p 144 Hz monitors with HDMI 1.4 only support 9.0 Gbit/s, only enough for 120 Hz over HDMI. Individual products may have limits below that. It does not mean every HDMI 1.4 monitor supports that bandwidth. However, that is only the maximum allowed by the standard. The maximum refresh rate available to you will depend mainly on the HDMI speeds supported by the monitor, which could be anything.Īnd don't be fooled by version numbers in this area many people will tell you 'as long as the monitor has HDMI 1.4, it should support 1080p 144 Hz', because the maximum bandwidth of HDMI 1.4 is 10.2 Gbit/s, which is enough for 1080p 144 Hz. If you want to run 1080p 144 Hz, you only need a High Speed HDMI cable, which is basically any HDMI cable.īut the cable is not really the important part. Any cables currently claiming to be an Ultra High Speed HDMI cable are fake. The certification procedures for this level are not finished yet, so these certifications are not being issued at this time. Ultra High Speed HDMI Cable - This certification level will certify cable for speeds of at least 48.0 Gbit/s, which is enough for 4K 180 Hz or 8K 50 Hz.Longer cables are less likely to meet this specification, so if you want a 10+ meter cable, make sure you get one that actually has a Premium High Speed certification. Most shorter HDMI cables (5 meters in length) will meet this specification (even if they are not formally certified). This means it will support formats at least up to 1080p 240 Hz, 1440p 144 Hz, or 4K 60 Hz. Premium High Speed HDMI Cable - Rated for speeds of at least 18.0 Gbit/s.Pretty much any HDMI meets this standard at least. This means it will support formats at least up to 1080p 144 Hz, 1440p 85 Hz, or 4K 30 Hz. High Speed HDMI Cable - Rated for speeds of at least 10.2 Gbit/s.This means it will support formats at least up to 720p 60 Hz or 1080p 30 Hz.

Standard Speed HDMI Cable - Rated for speeds of at least 2.2275 Gbit/s.The official certification categories are as follows:
