Hi. I bough one HP Pavilion 23xi one year ago and I was very impressed with the image quality. So I bought one recently, but I noticed a difference between them: when viewed from above or side, this latest one has light leaks and a not-so-uniform display of colors, which get washed out more quickly when viewed from other angles. This does not happen with the first one, and it's independant of operating system (tried on Windows 8.1 64bit and OSX Yosemite.
Is it a build quality or firmware issue?
Firmware of monitor 1: RIM111 / 2013
Firmware of monitor 2: RIM232 / 2014
Also the OSD is different between monitors - how can I update firmware RIM111 to RIM232 ?
Thank you.
