Frequently Asked Questions (FAQs) - SimplyAV™ & The Dongler® Products
The Dongler® brand adapter dongles are designed to work with most of today’s brands of displays and mobile source devices. If for some reason you cannot get a picture on the display device, we recommend the following: Test your connection with another HDMI cable directly from the Source device to the Display device. If you then get a picture, the issue has to do with either a poor performing HDMI infrastructure cable or an older legacy AVR (audio video receiver) device that the signal is being routed through that does not support newer mobile device sources. This can be experienced with some Microsoft Surface and Apple mobile devices used with legacy systems. Bypassing the AVR will usually solve the problem.
If you are using non-Dongler brand adapters and have encountered no picture, do the above test as well. Be advised that many dongles and adapters even sold today, do not support 4K content. Many cannot support even 1080p notwithstanding their published claims. Also, many dongles and adapters will overheat causing device shutdown and possible damage to device sockets and the HDMI infrastructure cable. Using high quality dongles and adapters such as offered by The Dongler® will eliminate these issues. For DP1.4, MDP1.4, and USB Type-C, the higher bandwidth requires the use of aluminum housing to better handle heat dissipation and eliminate device overheating.
