hello friends i have this problem with my monitor its an hp pavilion mx75, recently it has started to concave the entire screen, all applications run normally except the screen is concaved it will do so and correct itself or it will remain like that even if i turn of the monitor and turn it back on, i have tried degaussing it, also in case it was a virus i ran combofix and also scanned it with my a/v program microsoft essentials also ran super spyware and malwarebytes and hijack this in case it was something i had downloaded, all searches came back with no infections, i also updated my drivers using uniblue driver scanner and all drivers have been updated, now my question what could be causing this and is there a way to check if all settings are correct as far as my monitor status to make sure i did not accidentally move them, this is an old computer but still very dependable as far as what i use it for, here is a complete info on my system according to belarc advisor, thanks.

update: i went ahead and took the initiative and scanned my pc using eset online scanner, and it detected 3 infections all of them were called adware trojan dealio toolbar applications they were able to successfully get deleted using the eset software now the concaving has seemed to slow down a bit, but not sure if this could have caused this problem, any suggestions, any help would greatly be appreciated, thanks in advance.

Sounds like it is a CRT (picture tube) type monitor, in which case it has a fault in its east-west correction circuitry, and would need repair.
