I have a Mac Screen that doest have any ports, instead having only a thunderbolt 1 cable coming out of the back. i have a non-apple pc that doest have a thunderbolt. i do not want to spend $70 on a good adaptor. Help?
Presumably, this is the Apple 27" Thunderbolt Display (the only Apple-branded display 'with Thunderbolt 1 cable coming out of the back').
Unfortunately, that display will not work with anything other than a Thunderbolt connection.
Fortunately, these are not made anymore, so you may be able to find a buyer that has more cash than displays and you can have fewer displays and more cash.
