Problem detail:

Im facing a weird situation when im using my system. ive conected a second monitor in extended desktop mode, without any noticeable warning my resolution turns into 1024x768 in both Screens, and when i try to get the resolution back is a fight because it allow me to change the resolution again to 1366x768 in Laptop Monitor, but when i try to set AOC monitor in 1366x768 both goes into 1024x768 and vice versa, finally they work again but only in 1360x768 ,even when switching to 1360x768 it changes back to 1024x768, but is very annoying face this problem every day arround 2 o 4 times daily :(.

Here https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU I found the CRU program. It's free and it gives you the opportunity to change the resolution of all monitors you have with no headaches...
