HP Pavilion mx50 monitor bezel removal

I’m hoping that someone can help me with this problem. I have the above mentioned monitor that the power plug has gotten shoved inside the monitor case and I’m having a problem getting the casing apart to fix. I have removed the two bottom screws, but there doesn’t seem to be any screws towards the top of the monitor (???).
So, this is my problem, can you help please?
