Final Thoughts


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.
