Now days, new monitors have a 60 Hz Refresh Rate that gives you the option to change the Refresh Rate up to 70 Hz, if your monitor is compatible. A high performance monitor can set the Refresh Rate to 120 Hz. If your Monitor Rate is higher, your display is better and very comfortable. If you want to change the Refresh Rate then do that in the Control Panel. Windows selects the best display settings such as Screen Resolution, Refresh Rate and Color. You open the Control Panel and select the Adjust Screen Resolution under the Appearance and Personalization and click on it.
Definition: Repo rate is the rate at which the central bank of a country (Reserve Bank of India in case of India) lends money to commercial banks in the event of any shortfall of funds.
The Fed uses these two types of transactions to offset temporary swings in bank reserves; a repo temporarily adds reserve balances to the banking system, while reverse repos temporarily drains balances from the system. Repos and reverse repos are conducted with primary dealers via auction. In a repo, dealers bid on borrowing money versus various types of general collateral. In a reverse repo, dealers offer interest rates at which they would lend money to the Fed versus the Fed's Treasury general collateral, typically Treasury bills. Among the tools used by the Federal Reserve System to achieve its monetary policy objectives is the temporary addition or subtraction of reserve balances via repurchase and reverse repurchase agreements in the open market.
