I am starting to see computers with USB C on the host side. The future of one single connector to rule them all will be here soon. Wait a minute, we already had that, it was usb 2.0?!?!
- mac01021 8y agoI never saw anyone hooking up a monitor via USB 2.0
- reaperducer 8y agoI've seen them for sale on Amazon and elsewhere. I always thought they'd be neat to throw in a supplemental kit bag for a second display on the go. I think some of the smaller ones were even bus powered.
- DaiPlusPlus 8y agoThose are USB 3.0-based DisplayLink connectors. Any supposed USB 2.0-based display connectors (I’ve never seen any, I’m just speculating) would have been some VNC-like contraption involving an emulated frame buffer on the host.
- nintendo1889 8y agoI've seen those usb 2.0 display adapters and I never used one but I heard that they had low refresh rates and/or low resolution, due to the 5 volt limits. I personally use a usb 2.0 NIC so that I can be packet capturing on multiple switch/vlan/ingress or egress at the same time.
- bluedino 8y agoThey weren't that great but we had them 15 years ago. VTLink. Dual monitors for laptop users, PC or Mac.
- vel0city 8y agoI've used bus-powered USB 2.0 display adapters in the past, even up to 1920x1080. They're usually a software-based renderer writing to a frame buffer on the USB device. Big updates or lots of USB traffic meant dropped/torn frames, and lots of extra CPU power used to drive it. It worked well for word processing and light web usage, but you wouldn't be watching an HD movie on it.

- acomjean 8y agoBus powered and decent res (not 4k), but very workable for writing code a casual web browsing. I put a comment about my experience with one above.

- acomjean 8y agoI used the usb2.0 to dvi adapter a while back on a an old polycarbonate mac for which I wanted to drive a second monitor. It actually worked really well for that use case (coding/ web browsing). It probably wouldn't work at all for anything stressful. Getting the driver set up was a little challenging compared to the usual no effort required. The website for the product... well frankly not good. https://www.newertech.com/products/viddu2dvia.php https://www.newertech.com/products/viddu2dvia.php
- DaiPlusPlus 8y agoUSB-A/B for USB2.0 lacked the pin-count to provide compatibility with other connector standards by using a passive adaptor (except a few like PS/2). It also lacked the data bandwidth to encapsulate many other connector electrical protocols when using an active adapter except a few like RS-232 and 100mbps Ethernet. It also couldn’t deliver much power either - 500mA at 12V is only 2.5W - enough for a mouse or webcam.
- nintendo1889 8y agoTrue, I just realized that this is for display bandwidth. And also in the future, possibly for inexpensive 40gbps networking/video/gpu
- int_19h 8y agoFor me the true killer feature of USB-C is charging everything. Finally, a single charger for the laptop, the tablet, the phone, the router etc.
