Read PDF with OCR : Different output when using different Operating System

Hi Everyone,

I am using Read PDF with OCR activity(Microsoft OCR) to extract the data from a SCANNED PDF INVOICE.
The outputs are different when extracted using Win 7(1600 900 resolution) and Win10(1920 1080) and the output obtained from windows 10 is quite accurate whereas in Win7 I am getting garbage data.

I would like to know the reason why the difference is occurring and is OCR dependent on Screen resolution.
If yes, what is the ideal screen resolution to obtain quality results.

Please help!

P.S : I cannot share the invoice as it is confidential.
