Designed with the ability to support two video heads per channel, the ADDERView 4 PRO Dual Link DVI-I Video & Peripheral Switch from Adder allows users to control up to four computer systems and share peripherals between them using a single display, keyboard, and mouse. Dual-Link DVI-I support enables both digital and analog display compatibility at resolutions including 2560 x 1600 for medical imaging, 2048 x 1080 for 2K film post-production, or a maximum of 2560 x 1920. This version of the AV4PRO-DVI provides two total Dual Link DVI-I connectors per channel, allowing multiple video streams from each computer to be switched to two video monitors.

In addition to straight switching, the KVM, speakers, and two separate USB devices attached to AV4PRO-DVI units can either be switched in unison, as normal, or you can mix your peripherals between any of the systems to suit your current tasks. For example, you could be creating emails on one system, listening to a soundtrack from another, sending documents to a printer from a third, and performing a separate task with another USB peripheral on the fourth. The front panel on the AV4PRO-DVI helps make it easy to identify and control which peripherals should connect to each system. Additionally, USB True Emulation technology helps ensure the full characteristics of the connected keyboard and mouse are fully utilized on each system, including extra function keys, wheels, buttons, and controls that are commonly found on modern keyboards and mice.

The ADDERView 4 PRO Dual Link DVI-I Video & Peripheral Switch is well-suited for those working in architecture, graphic design, post-production, animation, banking, command & control, medical, and audio/visual industries. Supported operating systems include Windows, Mac, DOS, Linux, UNIX, BSD, Sun, NetWare, and more. Included is a 20W power adapter, a power cord, and four self-adhesive rubber feet.

General Features

Dual-Link DVI-I with Extended Profile DDC EDID
The AdderView 4 PRO features full Dual Link DVI-I video, delivering resolutions at 60 Hz. As the AdderView features DVI-I, you can also use a choice of digital or analog sources. The extended DDC EDID profile helps ensure that the switched graphics card is optimized to work with your screen, and the Dual-Link DVI-I capabilities further enable users to work at resolutions including 2K (2048 x 1080) for film post-production or WQXGA (2560 x 1600) for detailed medical imaging.
True Emulation USB 2.0 Technology
The AV4PRO-DVI features Adder's USB True Emulation technology. Emulated USB provides a rapid, reliable switching action and makes keyboard-hotkey and mouse switching possible. It also allows the use of extra function keys, wheels, buttons, and controls that are commonly found on modern keyboards and mice. Users in architecture, graphic design, post-production, animation, and more often need to use specialized interface devices, such as graphics tablets, 3D explorers, joysticks, and so on. The AV4PRO-DVI makes all this possible using Adder's True Emulation technology.
Independent Simultaneous Device Selection
Flexibility is key to the AdderView 4 PRO. The switch enables you to use the KVMA console to work on one computer whilst your USB peripherals are connected to other computers and your speakers are playing music from yet another. You can, of course, still switch all connected devices to any one of the connected computers as with any other KVM switch.
Channel Selection Options
The AdderView 4 PRO can be switched using selectable keyboard hotkeys, 3-button mice, or the front panel controls. Optionally, you can also use the RC4 remote switch to make your selection. These switching options allow you to reassign connected devices to any of the connected computers.
Broad USB 2.0 High Speed Device Support
A vast range of USB devices can be connected to the AdderView. From non-standard human interface devices to printers and scanners, this presents great flexibility. For example, you could be scanning a set of documents onto one computer whilst working on another and printing from yet another, all at the same time. The USB 2.0 switching action has been carefully engineered to ensure computer reliability when connecting and disconnecting USB devices.
Options Port for Control, Synchronization, and Upgrades
An 'Options' port enables the AV4PRO-DVI to be remotely switched using simple ASCII codes. When the channel is switched, the same ASCII codes are echoed to the 'Options' port and so, by linking 'Options' ports, two or more units can be switched in synchrony. The port enables a 4-button switch unit (RC4) to be used with the AdderView PRO. The same port can also be used to upgrade the firmware.
USB Remote Wakeup
USB Remote Wakeup feature is fully supported. Any connected computer can go into sleep mode and be awakened (when its channel is selected) as soon as you press a key or move the mouse. The computer and peripherals must support the USB Remote Wakeup feature.

Feels luxury, I approve
Size: King, Style: Warm
I have purchased high end comforters/duvet inserts and this one is somehow my favorite. It's so thick and fluffy. I was going to do the double duvet insert method to create an extra lush bed situation, but honestly it's not needed at all with this comforter! It poofs up wonderfully inside my duvet cover (king duvet, king insert) and it's like heaven. It's very cozy yet airy, and it moves well during the night and does not fee too heavy despite its weight. This thing is definitely on the warm end and probably won't be suitable for Florida summers, but depending on how you set the AC at night it could be fine! The comforter is weighty, it feels like quality, and has a soft fabric. I wouldn't use it without a duvet cover, that's more of an aesthetic choice but I like keeping it clean. The white is very white. Honestly, I will be getting another one simply because I'm so impressed. Definitely no need to drop $300+ dollars elsewhere.

Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.

Buy this instead of the ‘brand name’ one
Size: Twin, Style: Warm
Tl:DR: Buy it, it’s super cheap, better than the one I paid 2x the price for and soft as it can get, and it really is a ‘Winter comforter’. This review is going to sound like I got paid off for it but I actually didn’t. I bought another comforter prior to this one, paid close to double of this one and that the ‘on sale’ price, and it is trash compared to this Amazon basics one. Both claim to be thick warm comforters but I can literally stack two of the other brand and maybe they’d be almost as thick as the Amazon one. I only bought this one because the other ‘winter’ one I bought was so thin and flimsy I figured adding another ‘cheapie’ one might make me not freeze to death. As soon as I arrived I noticed that this Amazon one was WAY thicker, nicer looking, softer and warmer than the old one. Just to try it out I stacked both of them together to see if I wouldn't freeze to death like I was doing with the old ‘expensive’ one: five minutes in and I was sweating. That’s all it took, I immediately removed the duvet cover from the old one, switched it to the Amazon one and threw the old one somewhere where I couldn’t see the money I had wasted, and yes the Amazon was warmer and softer even WITHOUT the duvet cover. I’m probably going to get the light version for when fall hits and I don’t quite need the heavy one yet. Buy it you won’t regret it and hey it’s Amazon brand so if you don’t like it they’ll take care of you, but I HIGHLY doubt you won’t love this thing.

Great mid-weight comforter
Size: King, Style: Light
Great comforter, especially for the price. I put it in the dryer for a bit when I first got it and it became nice and fluffy. Perfect mid-weight duvet.
