Summary: I've found one either needs to switch out to DVI to get the display back, or just power cycle the desktop and monitor. It's happened a few times and it certainly is annoying when you are in the middle of something important.
Pros: QHD resolution is a vast improvement from the 17" SXGA that I've been using for almost a decade. 10-bit RGB color accuracy is excellent. 27" is a perfect size for 1440p, as I find the pixel granularity of 1080p to be bothersome above a 24" format. Matte screen finish is perfect for rooms with ample natural light and/or reflections. Wide viewing angles on this IPS far surpass TN/LCD.
Cons: I've encountered serious issues on occasion when trying to "wake" devices [attached to this monitor] from a sleep state. If the monitor is not turned off before the device connected to it enters a sleep or hibernation state (as my power profile is set to), the monitor will not recognize the signal once the desktop is powered on.
Summary: Don't even try to use the touch controls in a dark room. It's a recipe for failure.
Pros: I picked up two of these monitors during a sale newegg had a while back. I'm not sure it's possible to beat build quality and color quality of these monitors for the price I got them at. I'm a programmer, so I don't necessarily use these monitors for graphic design or photography. I was immediately able to tell the difference, however, when watching movies, playing games, or even simply editing highlighted text. The 2560x1440 resolution, the accurate colors, and the b...
Cons: Plugging in the USB to my computer causes the monitors to emit an somewhat audible high pitched sound when they're asleep. This sound normally wouldn't bother me, but it is burdensome when trying to sleep (they're in close proximity to my bed). My solution was simply to not use the USB ports on these monitors. That's okay though, as I bought these for their display quality rather than USB support.
Pros: Easy on the eyes, high contrast with no bleed through, vivid colors and menu navigation is a snap. The PIP (Picture in Picture) feature is very well done and maximum resolution is achieved with no scaling or distortion. The average user may not benefit from the maximum unless they have a mid to high grade video card.
Cons: The stand is a bit flimsy if you adjust the height of the monitor to the highest setting. The power cable has a wide body which prevented me from using the adjacent plugs on my surge strip. The monitor buttons are not mechanical, so if you accidentally touch them, they will respond.
Summary: * Lack of speakers, description implies that it has onboard speakers however audio is only a pass through.
Pros: * Wonderful picture and quick response time.
Cons: * Was basically DOA for me. Worked great for the first hour and then the picture froze and went black. Even the OSD wasn't possible to bring up. Trying to restart it showed a brief image of some colored vertical lines which then disappeared, faint grey lines then appeared and disappeared until it turned itself off.
