Ultra HD 4K screens are in healthy supply at CES 2014 but super high-resolution monitors, however, are comparatively few and far between. Luckily, picking up the slack, there was Philips' Brilliance 288P Ultra HD 4K monitor. We met up with Philips to check out its latest 28-inch 4K addition that offers PC gamers and users a 3840 x 2160 resolution. Philips also boasted that the Ultra HD set features 10-bit color panel, 2-bits more than most other screens. Fixing the TN panel We were a bit shocked when a Philips PR rep told us the monitor was a TN panel. Classically these fast response time monitors are tuned for lag free gaming, sacrificing good color and viewing angles. The Philips Brilliance 288P isn't hindered by either of these issues. Colors are deep and rich, it's still not the most vibrant color gamut we've ever seen on a 4K display, but it's definitely a step up from the washed out hues usually seen on TN panels. However, we can't say much about the bla...

LG and Samsung don't like to be outdone by one another, so it wasn't only Samsung that debuted a 105-inch curved Ultra HD 4K TV at CES 2014 this week. LG always have the first official press conference of the show on the Monday morning and so it was quick to claim the "world's first" 105-inch tag, which it took full of advantage of in the hours before Samsung made its announcement. So what are these 4K curved displays actually like? And do we really need curved TVs? The first thing is that this screen - model number 105UB9 - is massive and as such is somewhat impractical. There will be those buying 105-inch TVs of course, but LG knows it is a tiny percentage of even early adopters - not least because . As it turns out, it has made a 65-inch version, too, which you can see here: The advantage of curved is in the viewing angle, though we remain to be totally convinced. One thing is clear though, the viewing angles are as wide as you like - the picture is extremely...

Critical software flaw restarts UI when trying to remove a user-installed application A second ugly software bug has reared its head in the Sony Z Ultra Google Play edition . Applications installed from Google Play can't be uninstalled — the process instead causes the entire phone UI to restart. This is the second serious bug found in the software on the Z Ultra, the first being no way to open the "Security" section of the device settings, as found by JR Raphael  at Computerworld .  Both bugs are more than mere inconvenience to the user, and present security as well as usability concerns. This latest bug affects all user-installed apps, and is present regardless of network state. We were unable to test side loaded applications, as access to side loading is currently blocked because we can't get into the security settings. We can't be 100 percent certain we are running the final consumer build of the operating system, though we have questions out to Google a...
