It may be the resolution of your devices. Or it may be whether your cable is built for 4K or not. ##### 4K ADAPTERS ARE POWERED  To adequately deliver 4K content to your screen, our DisplayPort adapters require power. Therefore, they must be plugged directly into a source with adequate power. If you are using a laptop, ensure that it is on line power and not on battery power. These adapters draw nearly a full watt of power when active. They do not share power. If you use a 4k adapter, the cable cannot be an active cable. ##### CABLE SIZE & LENGTH MATTERS Our 4K adapters are usually rated for a patching cable of 2 meters or less in length. We have confirmed 15 foot Premium Certified HDMI cables work. We have also noted that cheaper cables start to have issues over 2 meters. In addition, the gauge (AWG), or diameter of your cable wires makes a difference. Use of micro 32 AWG or smaller will cause failures. Use at least 28 AWG wire for best results. ##### NO ADDED HARDWARE 4K adapters are meant for a source to display connection via a single cable. Connection to switches, distribution amps and extenders can introduce interoperability issues. They also cannot be patched to a wall plate or similar coupler on a panel. It must be a direct device. Follow these few recommendations and you're chances of a great 4K meeting are meant "to be!" :-) Topics: [HDMI](https://blog.libertycable.com/topic/hdmi), [4K](https://blog.libertycable.com/topic/4k), [DisplayPort](https://blog.libertycable.com/topic/displayport), [Adapter Ring](https://blog.libertycable.com/topic/adapter-ring), [hdmi adapter ring](https://blog.libertycable.com/topic/hdmi-adapter-ring) -
