i hope someone can give me a hint how to solve this problem:
i am using win 8.1 and lightroom 5.7.
i have a laptop with an amd radeon hd 8800m grafic card. and a second display attatched.
my laptop has a native resolution of 1920 x 1080 px and my second screen can display 2560 x 1440 px.
on my second (big) screen i am having my main window of lightroom and on my laptop monitor i like to display an additional grid-view of my library.
but for some reasons lightroom only recognises 1600 x 900 px of my laptop monitor.
so when i am displaying my library in full screen mode it looks like this (the laptop display on the right):
weired, right? remember: this is not a window. it's full screen.
when im reducing my resolution to 1600 x 900 px everything looks ok but i don't like this solution...
i don't know if its a lightroom problem or a windows problem.
but sure enough it's a problem...
sometimes i managed i trick my computer by reducing the resolution and enlarging it back again. it worked two times but when i do it now it doesn't work anymore...
and the problem doesn't occur, when i am having the main window on my laptop and the additional full screen window on my large monitor. there everything works perfect.
hope anyone can help me!
