StarTech.com USB 3.0 to Dual HDMI Adapter, USB to 2x HDMI Monitor Converter for Windows, TAA (no support for macOS/ChromeOS/Linux)

This USB 3.0 to HDMI adapter let me successfully use my Dell Inspiron 15 3530 (plastic chassis model capped at 1080p) at 2k and 4k. I believe this adapter works given that it uses its own external graphics driver ("Connected to Trigger 6 External Graphics") and therefore not reliant on the PC's limitations.To give some background, it was apparent that this Dell 3530 was limited to 1080p from some hardware limitations and its typical display ports based on the official tech specs below:-USB 3.2 Gen 1 Type-C port (for computers shipped with a plastic chassis)-HDMI 1.4 (Maximum resolution supported over HDMI is 1920x1080 @60Hz. No 4K/2K output)Before this adapter, 1080p via native HDMI was both grainy and stretched. Not good for productivity or the eyes. Given that HDMI was capped at 1080p and the USB-C port did not include DisplayPort Alt Mode 1.4, my options were to buy a new laptop, settle for an inferior display at 1080p, or find a workaround solution.From some online searches, a potential workaround solution was in the form of a USB 3.0 to HDMI adapter which led me to this product. While using an older USB-A port seemed counterintuitive at first, this was a successful solution. Although it took a minute, installation was plug and play, and my PC detected both 2k ultra-wide and 4k wide displays tested without the need to download or update any drivers.The dual monitor feature also works well, though I had to first connect my 2k monitor to the 4k display slot to maintain its ultra-wide fidelity, then connect my 4k TV to the 1k display slot (displaying at 1k). The 1k was slightly over scanned while using dual displays, though this is hardly an inconvenience overall when my main intent is to use my PC with a single ultra-wide monitor.The resolution displayed is crisp and smooth. The adapter itself is lightweight plastic and appears well-built, though time will tell on its long-term reliability.Hardware used and tested:PC: Dell Inspiron 15 3530 (max 1920x1080 at 60Hz)Display adapter (this product): StarTech USB 3.0 to Dual HDMI Adapter, USB to 2x HDMI Monitor Converter2k display: Samsung Ultra-Wide HD LS34C650TANXGO monitor (3440x1440 at 50hz)4k display: Samsung 55" UN55MU6290 TV (3840x2160 at 30hz)

Plug and play USB to extended dual monitors plus laptop screen. I am blown away. I was about to buy a Lenovo dock for $100+ in order to extend my desktop screen to two extra monitors but THIS is what I needed. No drivers to download, no hassle, connected automatically and then I changed the display from duplicate all three monitors to extend. Works perfectly as expected.* Second day of use update: I unplugged the usb side of the dongle with the hdmi cords still plugged in on the other side. I worked on my laptop for a bit then came back and plugged in the usb side of the dongle and it didn't work. It only worked until I unplugged everything from the dongle and then one by one put the usb side in first then I heard the usb connection sound, then plugged in the hdmi cords and it worked. It seems to be a little finiky but still 5 stars! More to come.

Worked great! I had previously tried two other brands that did not work with my computer. One would flicker the monitors and the other would not even bring up the second of dual monitors. I am going to buy a second one just to have as a backup. I will recommend to friends.

I’m not very hardware savvy so I was a little skeptical about the hdmi to usb connection being able to receive signals from both monitors at once, but it does! Just had to plug in the usb first, wait a minute for the driver to setup, THEN plug in both monitors, and it works perfectly!

It was too slow to stream you tube to my TV while running a second monitor at 1080HD. It could be my laptop is not fast enough. I will try it on a faster system.

Shortly after the return period ended on my brand new laptop I discovered that even though it was a new model, it did NOT have usb thunderbolt capability, just usb 3.0. Meaning my laptop docking station and extended displays did not work. I really wanted 2 monitors though, so after a whole bunch of research I found this product.IT WORKED!!!!!!!!That's all I care about. I am EXTREMELY pleased.I do have windows 11 and it does work fine, fyi.

use for work- works great!

Definitely works as intended. Slight pain to get functioning if you need to update your drivers, but it’s worth it’s money.
