How sharp is the image on your PC monitor? If you haven't tweaked the default settings, you're probably not getting the best picture possible. And different functions call for different settings. If you're a graphic designer, video editor, or someone who likes to watch DVDs, here are some calibrating tips to get the sharpest image on your screen.

Every now and then we may pop off a message and immediately regret it. Whether you misspelled your manager’s name or have second thoughts about the angry rant you just sent to your spouse, there is a solution if you act fast!

Gmail accounts allow you to Undo send, which means you can stop the message you just sent from going to the recipient. All Gmail accounts have this feature, but you can choose the setting for how long the recall period will be.

To set the time frame, go to the gear icon as above and scroll to Undo send. Click the drop-down menu to set the cancellation period, which can be in the range from 5-30 seconds. If you have not set this time period manually, the default is 5 seconds. After you set the cancellation period on a computer, it should sync to your Gmail app as on your mobile device as well.

Once you have your cancellation period set, you will have that amount of time to stop your message from going out. To use this feature, just look at the bottom of your screen after you have hit the send button. A pop-up button will appear saying Undo. Click the button and the email will not be sent, allowing you to edit or delete the message.
