A Must-Have Accessory!
Reviewed in the United States on June 16, 2019
This device is absolutely amazing and, more reliable, and better suited to my needs than the other WARRKY USB-C to HDMI (female) adaptor that I had purchased weeks earlier! This is the PERFECT accessory for ANYONE with a Samsung S9 (and presumably S9+, S10, and S10+) phone, such as myself, particularly with Samsung’s DeX desktop application. However, ANY cellphone (or other devices) with HDMI capabilities on their USB-C port will appreciate the plug-and-play capabilities this will provide with ANY HDTV or monitor with an available HDMI port. I still use the other WARRKY adaptor with the female HDMI connection with HDTV’s (such as my parent’s) where I don’t have good access to an open HDMI port on the back of their TV, borrowing the HDMI cable from an existing device (DVD player, set top box, etc.). However, it appears that this single-cable solution is a more reliable and elegant solution than the 2-cable solution (adaptor + HDMI cable) for those with an open HDMI port on their HDTV or other hi-def monitor. Screen mirroring is great in that it does not add anything in terms of cell data usage but provides a far better viewing experience than does a relatively-small phone or tablet screen. And for those of us with access to Samsung Dex (via our newer Samsung phones), DeX provides a true 16x9 viewing experience, eliminating the “black bars” around the displayed image due to discrepancies between your monitor’s aspect ration (typically 16x9) and cellphone (18.5x9 in my case) - again, without incurring additional cell providers’ “hotspot data.” In conclusion, I consider this to be a “must-have” accessory for compatible cellphone users, particularly for those who don’t have (or wish to pay for) reliable access to home Internet service providers.
Update: CLEAN YOUR USB-C PORT! This thing started getting flakey on me several weeks ago (intermittent HDMI connectivity, screen suddenly going blank/ black, etc.) and, because it's summertime here in the northern hemisphere, I was assuming the adapter and/or phone was overheating. Nope! It was due to crud building up inside the phone's USB port that was compromising the connection by not allowing the HDMI adapter cable to fully seat into the phone port. The remedy: With your phone OFF, use a tiny, NON-CONDUCTIVE object such as a wooden or plastic toothpick (what I used) and run several laps around the base of your phone's "male" portion of the USB connector until you have created a nice little "dust bunny" that you can then lift out of the connector region. I would NOT recommend using isopropyl alcohol to do any further cleaning (as I did) unless you are extremely comfortable with doing so and understand the ramifications (at minimum, setting off the moisture sensor). Some compressed air following the aforementioned procedure is probably a better option. I hope this helps someone else out there as well!
