When it comes to connectivity the CA750 is unparalleled. We can say this without exaggeration because no other monitor in the world offers the wealth of options available here.
First, let’s talk wireless. The CA750 series uses UWB (Ultra Wide Band), on which wireless USB 2.0 is based, to offer plenty of bandwidth (up to 500Mb/s) for video and audio streaming, and more besides. Range is up to three metres, though this may result in reduced quality and Samsung only guarantees flawless transmission at up to 75cm – still more than enough for most scenarios.
Unfortunately, this solution is not quite plug and play, as – unlike DisplayLink devices – no drivers are stored on the dongle and the setup requires a driver to work. Installation of this was painless, if somewhat lengthy. Once everything is set up and you turn the monitor on, it should ‘handshake’ with your PC in less than a minute, after which it never needs to go through this process again.
Detection was seamless on most of our test machines, though on one Optimus-equipped laptop the driver did have some issues, only allowing us to set a maximum resolution of 1,280 x 720. However, we are dealing with a pre-production sample here so Samsung has plenty of time to fix little software niggles like this. Otherwise it all worked perfectly, allowing the desktop to be cloned or extended. Samsung has a very impressive wireless solution on its hands, especially since it passed all our tests with flying colours in both audio and video.
Not only that, but the CA750 truly deserves its billing as a Central Station, since in addition to handling video and audio the wireless system gives you access to the USB hub (though naturally the USB 3.0 ports will only run at USB 2.0 speeds) and a network when connected through the non-Gigabit (100Mb) Ethernet port.
It’s impressive stuff: plugging your laptop into the CA750 is like giving it a docking station and monitor all in one, and it’s completely wires-free! Apart from the power cable, of course.
Of course, if wireless doesn’t take your fancy or you need the extra bandwidth and want USB 3.0, just plug the provided USB 3.0 cable into the matching port at the rear of the monitor’s stand and a computer that supports the new standard. This will give you unlimited access to the CA750’s four-port hub, offering two USB 3.0 outputs on the left and two regular USB 2.0 inputs on the right. USB 3.0 not only allows for three times faster data transfers (as we saw in our testing), but can also halve charging time for devices like mobiles.
Sensibly, Samsung hasn’t included speakers, which would frankly have been a waste of space and money. Rather, there’s a far more useful 3.5mm headphone jack that you can also use to hook up speakers. Audio output from this was a touch noisy over wireless but otherwise flawless.
Also on the base’s left we have an HDMI 1.3 port, while around the rear there’s good old VGA. Out of the box, this means the CA750 can be connected to four different computers (though only two will be able to access the USB hub and Ethernet), while buying additional wireless dongles should mean you can hook up as many PCs as you like – just keep in mind that they all have to share the same screen and limited bandwidth. Likewise, you can connect up to three monitors to a single computer wirelessly or using USB 3.0 cables.
