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.
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: 2. OSD controls are touch sensitive and placed in an awkward position (under the bezel)
Pros: Just to begin, be aware this is a wide gamut display and as such, colors will be very saturated vs displays that follow sRGB only. However, this display DOES have an option for sRGB for those that want that.
Summary: For this price you have to expect a professional monitor. And that is what you get. This is my first pro monitor and it is truly an astounding product. You just simply cannot compare it to monitors in the $4-500 price range. It has a wealth of features, adjustments, and settings. A quick glance of the connectors: DVI, Display Port, HDMI, 3x USB 3.0, headphone/audio port.
Pros: Performance, Style/Design, Easy To Use, Features/Settings, Quality
Summary: Il migliore che io abbia mai visto da vicino: i colori sono vivacissimi e regolabili via hardware. L'unico difetto che gli posso trovare è che il menù non è usabilissimo: i bottoni per navigarlo si trovano sotto al bordo dello schermo e bisogna smanettarci un pò prima di farci la mano.
