Dell Latitude 830 Display info is hidden!

My Display resolution is 1680x1050 at 60 mhz refresh rate

I've wasted 3 HOURS!!!! of endless searching for display information at support page of dell site, then by < ADMIN NOTE: Service Tag removed per privacy policy >, then in user manual, quick reference manual and service manual and googling FOR:

Display vendor name ?

Horizontal scan range ?

Vertical scan range ?

But absolutely NOTHING comes out!!! :emotion-39:

Obviously dell doesn't want us to know this information and makes our lifes harder by pointing us to informations dell want us to know instead!

AND GIVE ME BACK, MY TIME AS WELL!
