The processor has no effect on the video output. You need to match PC video outputs with TV video inputs, and audio. If there is no match you either change video cards (or add one) or chage TVs. And USB does not carry video. Round one?

Since there are a gazillion video and audio connections ranging from analog (what you have now) to digital, HDMI. You really need to get familiar with the connection types, then investigate what the PC uses and has available. Look at the video inputs on the TV. Find a video card with the same outputs.
