Samsung Central Station SyncMaster C23A750X review: Samsung Central Station SyncMaster C23A750X

Recommended settings and use: We found the Game and Cinema presets were indeed the best choices when viewing games and movies, respectively. As we mentioned above, when viewing photos, there is a slight tinge of green to faces, but this can be resolved with the following settings:

Preset: Custom
Red: 55
Green: 44
Blue: 50

It would be an incredibly tall order to find a monitor that failed at performing general tasks, and indeed when for use of Word or Excel, surfing the Internet, or any other casual endeavor, the C23A750X gets the job done without any problems.

The C23A750X isn't suited to tasks that require very accurate color, given its TN roots. If precise color values are something you require, an IPS monitor like the excellent but much more expensive Dell UltraSharp U2711 is much more appropriate.

Central Station
The C23A750X is obviously more than just a monitor, and in this section we'll describe our experience while using it as a wireless docking station.

We used two laptops and a desktop to test Central Station using the included wireless USB dongle. There's also the option to use a traditional wired USB connection, but that's just not quite as exciting.

After we installed the drivers, the dongle didn't detect the C23A750X until we opened the Hub menu on the monitor and turned on Auto Wireless Detection. In two out of the three installations we conducted, it was also necessary to access our Windows screen resolution control panel and make sure the C23A750X was enabled.

According to Samsung, the USB dongle connection has a 5-foot-radius limit and beyond that things aren't expected to function as smoothly, and will eventually not function at all. We found that we could get about 6 to 7 feet away before severe lag hampered our experience. When we brought the laptops back into the C23A750X's wireless radius, performance suffered for a few seconds as the monitor resynced, before working smoothly again.

We looked at "Green Lantern" footage from WonderCon using QuickTime and noticed a small drop in quality when playing the movie over wireless USB rather than HDMI. This can be seen in the very first scene, as Sinestro, back to the camera, walks toward the Corps. Using wireless, there's obvious pixelization on the small of his back, but through HDMI, no pixelization is evident. When playing Call of Duty: Black Ops wirelessly, there was a definite degradation in visual quality in the game and a noticeable dip in frame rate, but control responsiveness didn't seem to be affected. In static, high-resolution photos, we saw no obvious visual differences between the two connection options.

Keep in mind that we were looking for these inconsistencies and most viewers would not notice the difference. Still, it must be said, at least for video and games, you won't see the exact same visual quality using wireless that you get from HDMI. If for whatever reason you're looking at reference material that requires precise color values, you'll probably want to use HDMI, just to be safe; however, if that's the case, you'll likely want to use something more accurate than a TN-based panel monitor in the first place.

The C23A750X has the option of turning on an accelerated charging rate for its two USB 3.0 ports. Although the ports charged our iPhones faster than USB 2.0, plugging the phones directly into the wall was still the fastest charging option.

We experienced some instability with the Ethernet port and had to make sure our Ethernet cable was pushed as far into the port as possible. Even while it was locked in, if the cable was not deep enough in the port, the network would drop.

The Alienware M17x conundrum
When we tested on the Alienware M17x, we ran into a few problems that we couldn't reproduce on the other two test systems. It should be noted that the M17x was being used as a workstation before the tests and had many programs installed on it, a high number of which launched at start-up.

First off, we were unable to connect the C23A750X to the M17x in clone mode. There was an option for extend mode, but none for clone. Also, with tons of programs running in the background, the M17x occasionally froze when switching from HDMI to the wireless connection, forcing a hard reset of the laptop, before it functioned properly again. After disabling most of those start-up programs, we no longer experienced this.

On one occasion, when we took the laptop out of the C23A750X's 5-foot radius and then reentered it, the screen went black on both devices and we were unable to revive it, again forcing us to restart the computer.

To be clear, when using "cleaner" test systems, which were an Asus G73Jw and a newer M17x, we had no difficulties. The syncing just worked. You can leave the area with your laptop, come back to your desk hours later, and experience the satisfaction of your laptop automatically syncing with Central Station again, without needing to open the laptop or press a single button.

Power consumption
The Samsung SyncMaster C23A750X achieved fair power consumption, with a Default/On power draw of 29.6 watts, compared with the Samsung PX2370's 25.01 watts in the same test. In our Sleep/Standby test, the C23A750X used 2.8 watts and the PX2370 pulled a lower 0.27 watts. Based on our formula, the C23A750X would cost $10.78 per year to run, compared with the PX2370's $7.65 per year.

Service and support
Samsung backs the SyncMaster C23A750X with a three-year parts-and-labor warranty that covers the backlight. It also offers support through a 24-7 toll-free number, as well as 24- to 48-hour turnaround e-mail and Web chat support.

As a traditional display, the C23A750X performs well, with the same vast number of OSD options we've come to expect from Samsung monitors. A few idiosyncratic differences it had with one of our test laptops aside, the C23A750X also works as a wireless docking station.

As good as its functionality is, however, we feel the $450 price is a too high. The monitor itself would probably run about $300, and as novel and useful as the added functionality can be, we doubt it would be worth an extra $150 to most users.

That being said, if you have the money to spend and are a laptop user who is constantly moving around with it, Central Station provides a level of convenience you've likely never experienced, and it will probably be of high value to you.
