Today we have the chance to have a look at the Samsung SyncMaster CA750 LED 27" wide screen LCD with a 1920x1080 @ 60Hz.  It supports a wireless USB connections, USB 3.0, USB 2.0, Ethernet and HDMI. It comes with a dual hinge base that allows it to sit nice and low or tall enough to sit above your laptop screen for some great dual-screen possibilities.  The biggest features of this 27" display is not the resolution - at 1080p, it doesn't have the tightest pixel density at all - in fact some 15" laptop screens have the same resolution on a panel that is 12" smaller.  The biggest feature is the wireless display technology.  Samsung has combined this wireless screen technology with their "Central Station" which turns this into a pretty robust wireless docking station.

The Wireless Display (WiDi) technology is probably one of the biggest selling points of this $500 LCD, and if you're not familiar with this Intel piece of technology, make sure you check it out over here to see how it all works.  We'll find out later if there is enough bandwidth to really make it work well.


First Impressions:

When I first opened the package, I was almost overwhelmed at the size of this LCD.  I'm used to a 19" LCD so the move up to something this much bigger took a while to get used to.  I had to clear out some extra space on my desk so I could take a look at everything that came with it.  Included in the box is the external power brick for the display, as well as various manuals, quick install guides, a VGA cable and the wireless dongle for use with your laptop or desktop PC.  As a bonus, Samsung also threw in a nice little cloth for cleaning your screen.  The finish is glossy so you're going to need the cloth on both the front and back if you want to keep it looking spiffy.



Closer Look:

According to the specifications and features, this is no ordinary monitor.  As we take a look around the base of the unit, you'll probably agree.  Their are no connections on the panel portion of the LCD itself as all of the connections happen in the base.  This is not a first for Samsung as we saw the UN55C9000 Ultra-thin 3D HDTV do the same thing.  The idea is pretty slick for sure and it allows for the cable connections to be kept low on your desk and helps tame the cable clutter that can happen - especially if you plug cables into every port on this display.  If you filled every port (2x USB 3.0, 1x HDMI, 1x Headphone, 2x USB 2.0, 1x VGA, 1x Ethernet, 1x USB 3.0 uplink + power) you'd have quite a lot of clutter.  Having the ports pretty much level with the top of your desk will greatly help.

It's interesting that their is no DVI-D connection on this screen.  It only supports the older 15-pin VGA connection as well as an HDMI connection.  It is of course HDCP compliant so you can plug in your favorite HDMI-enabled Blu-Ray player without issues.  The VGA connection ensures that it will work with a wired connection from older computers.  I guess, the big features is still the wireless USB dongle that allows you to keep everything connected without plugging a single thing into your laptop.  It is a great idea - if it works as advertised.

On the last page, we'll cover testing as well as share our final thoughts as we wrap up the review.


Performance - Text:

While I'm certainly a gamer, the truth is that the majority of my use and is text and internet browsing.  I love large screen size of the C27A750X as it allows me to put two web pages on screen side-by-side (Windows 7 is great for this).  I was very pleased with the overall text quality.  The resolution on this 27" unit is fairly typical 1920x1080 but the large dot-pitch can make some small text appear a bit fussy.  The truth is that even with a screen this size, you will often site the same distance away from it as you would a 24" unit so while things are larger, the coarser dot pitch makes some things not quite as clear as on a 24" or 22" 1080p display.


Performance - Video:

I didn't have much time to watch movies, but I did make sure to watch some movies on the C27A750X.  Both VGA and HDMI connections performed very well and I noticed no issues with the screen for watching movies.  The large 27" screen size is great for watching movies at your desk and if you've hooked your PC up through the VGA or wireless connection you can use the HDMI for use on your Blu-Ray player, Xbox 360 or PS3.

We used a monitor test to check out color uniformity and color banding.  Overall, the monitor performs quite well in these areas.  There is slight banding on some tests and the grey gradient test, but I've yet to see a monitor personally that can pass this without any banding at all.

Performance - Gaming:

I'm a gamer so I couldn't wait to test out the quality of the 1920x1080 display.  This was hooked up to my ATI Radeon HD 5850 graphics card with all of the eye-candy turned up.  I enjoyed playing Call of Duty: Black Ops on the unit and couldn't get over how great everything looked.  It was so crisp, clear and bright compared to my 19" LCD.   I also played some Call of Duty: Modern Warfare 3 on it through the HDMI connection and again it was a great experience.  There were no hiccups or ghosting issues at all on the display as it comes set with a 2ms grey-to-grey response time.  This should make everything that is connected to the wired interface run great.

I used the headset connection as well as the display will take audio from your HDMI connection and output it through the analog 1/8" jack.  I found that the signal processing in the monitor leaves a bit to be desired as the audio through the headset jack wasn't all that great.



To test out the wireless you will need to put the CD in your machine and install the drivers.  This procedure takes a bit of time to setup properly - but once it's done it's a pretty nifty feature.  In order to make everything as seamless and "wireless" as possible, it's a good idea to have a wireless keyboard and mouse combo hooked up to the monitor.  If you have an extra wired keyboard or mouse, you can use this as well and it will still connect wirelessly to your PC when the screen is connected wirelessly.

The image quality wasn't too bad at all, but for fast-moving video it did become a little pixelated - it wasn't major, but it was noticeable on video so keep that in mind if you are planning on using it primarily as a wireless display for full 1080p video.

As far as distance goes, the video was able to play pretty smoothly at a distance of six feet but when moving out to 8 - 9 feet, it started to lose signal.  The WiDi technology is meant to be used a quite a short range and for this it works very well, but if you try and extend this beyond it's designed range, you'll be disappointed.  Samsung promoted and demo's this unit as a wireless dock for your laptop that is used within a foot or so of the display and this is definitely it's sweet spot and it does work very well for this.

It's pretty remarkable that you can have your printer, external hard drive and media player or phone plugged into your LCD and when you're laptop gets within distance - everything gets connected and works.  It's very surreal the first few times it happens.

USB Connection:

When testing the USB connections, the best way to take advantage of the wireless connection to your PC is to use a wireless keyboard and mouse.  This makes everything run very smooth but the video tends to pixelate.  If the image quality degrades too much it will scale the resolution down to 1280x720p, but it's too bad that it can't run at a full 1080p - and do it smoothly.

If you want to change inputs from wireless to HDMI or VGA (analog), you can do this very simply by controls located on the base of the monitor.  There is a selection pad that allows you to use directional arrows to change from any of these inputs.


Final Thoughts:

The C27A750X 27" LED Backlit Wireless LCD is a very nice monitor for a 27" display.  When connected by HDMI, it is super clear, crisp and will be an attractive addition to any desk workspace.  If you use and enjoy multiple connections - such as the USB 3.0, HDMI and VGA connections it works very well - especially if you're set up with a wireless mouse and keyboard.  I'm not into changing screens between multiple computers, but it was nice for testing for sure.  I know that Zeus would be all about this display as he could hook up his Xbox 360 to it as well as his laptop and main gaming rig.

The price is a bit steep at $600, but I've found it online for as little as $500 - and for that price, it might be a compelling buy for someone that wants a wireless display and a hub to get things done faster without plugging in everything.  For me personally, it has features that I wouldn't use very much, but for a power-user that wants more than their standard monitor has to offer, the C27A750X has a lot more to offer.  For those of you that simply want to connect it to one machine and watch movies or play games on a monitor, it may be more than you need.  Still, it is a very nice setup.

The build quality of the C27A750X is pretty decent for sure.  It seems to be quite solid and should provide years of service.  BCCHardware has tested some displays that have felt very cheap; nothing about the C27A750X is cheap.

The dual-hinge design is quite simple and yet provides a lot of flexibility for height adjustment and this will work well beside another display or above your laptop.  I'm a fan of this design as it looks much more stylish than a simple telescoping stand.


  • Nice big screen
  • Sleek, thin design
  • Great image and video quality when connected by wires


  • A bit expensive at ~$550 for a 1080p display
  • More options than I would use
  • Audio out (Digital HDMI -> Analog Stereo) not great quality
  • No HDMI Cable




I'd like to thank Samsung for sending us this display for us to review.  I will certainly miss it and dread going back to my 19" widescreen LCD.
