How to display a conference slogan (red text on a yellow background) full screen on a large monitor?

Let me answer you: It’s very simple. Use WPS office software. The first step is to make an A4 horizontal frame with a yellow background frame, then enter text to turn it into red, and then you can output the document as a picture. When finished, you can also take a screenshot directly. The second one is super simple. Use coreldraw software to do it. Export the picture and it will be done perfectly. If you have software.
