No, your TV is a commercial-type monitor, so it has no tuner in it. Bummer!
The set has component and PC-connectors, but does not have HDMI inputs. You will need a tuner that provides component (red, blue and green) connections.
eBay is full of good HDTV digital tuners, however you need a true HDTV TUNER, NOT a converter box. Digital ATSC HDTV tuners will output a true HDTV signal: digital converters will NOT.
The Samsung DTB-260f is one of the best HDTV tuners that was made; they are no longer made, but can be found for about $150.00 on ebay:
