DVI Tx in Cyclone III

If you are looking for an oscope to look at DVI signals, it won't be cheap. If you are using lower video resolutions, you could get by with a less expensive scope. Take the maximum bandwidth of your signal and multiple it by 2x. Look for scope with this bandwidth. The DVI runs at 10 bits per clock, at a pixel clock of 100 Mhz, the data rate is actual 1GHz. I would prefer at least a 2Ghz scope.
