SimplyAV™ - About Us

The Dongler® is the first true universal HDMI® dongle adapter ring holder. The Dongler’s innovative and patent pending design easily and securely connects various mobile devices to projectors, video walls, TV’s & monitors.
We are leading developers with HDMI and DisplayPort technologies. Our cable and interconnect technologies are sold worldwide under several different well-known international brands in the AV, ProAV, DataCom, and Security industries.

Prior to The Dongler®, no other ring type solutions supported the latest 4K technologies.  So, with the help and recommendations from leading AV industry professionals in the USA and Europe… The Dongler® was born.

We developed The Dongler® to be a true universal HDMI dongle adapter ring holder. No matter the brand or type of pigtail dongle or adapter, all can be quickly and securely attached to The Dongler®.


Our industry leading dongles support the latest 4K HDMI, DisplayPort and USB standards. Our dongles support HDMI v2.0b with 4k@60 4:4:4 18Gbps plus HDR; DisplayPort 1.4 supporting 4K/8K up to 32GBPS (input); and USB Type C 4K.

The quality of our dongles is unmatched in the industry. We feature aircraft aluminum housing for better heat dissipation that is necessary for any true 4K content. We tested so many brands of dongles and adapters and found that most of them only supported up to 9Gbps…which isn’t even 1080p and so far away from the 4K@60 4:4:4 18Gbps that is becoming the standard today. 

We are so confident that you will love your Dongler that we are now offering a Limited Lifetime Warranty on The Dongler® adapter ring and Dongler Harnesses.
The Dongler® is built to last and support your AV connections for many years to come.  We thank you for your interest in The Dongler® and please check back often as we have more development and new items supporting The Dongler® coming out soon.
