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.
While the mechanics of a repo involve buying and then reselling securities at a set price and a set time, at its financial essence, a repo is a collateralized loan. Fed repos can be conducted for terms anywhere from one to 65 business days. They are usually overnight, though rarely longer than 14 days.
