A:Answer Technically, yes (providing your computer outputs via HDMI). The resolution will be lower than you may like, =- however. A 720p television has a resolution of 1280 x 720, so even though the monitor will be big the resolution will be low. Most entry level computer monitors have a resolution of 1920 x 1080.
If this is going to be a secondary monitor (for presentations, etc.) it would work fine.
