Last week I wrote about not being able to get my VGA to Component cable on my DVD player working with my new LCD monitor. Alright. There’s many different types of VGA connectors. Makes sense. mmm. The LCD has a DVI-I port which is compatible with DVI-D and DVI-A cables. Bought a new DVI-I cable cuz I thought it was gonna work this time around. Whadyu know? It’s not. WTF dude. Seriously.
Before I end this short post, I want to summarize my findings below.
LCD or CRT Computer Monitors are…
NOT compatible with signals coming from an analog output because it only has digital video inputs. Even if the cables fit right-in the ports, it ain’t gonna happen with your DVD player or other devices unless there is some form of a digital signal passing from that external device to your LCD.
Examples of cables that output analog signals: Component (RGB), DVI-I/DVI-A, VGA
Examples of cables that output digital signals: DVI-D, VGA
TV Tuners cards (computer add-ons or stand-alone devices) can take analog broadcasts and push it to your LCD as digital.
DVD Player —(Analog)–> TV Tuner —(Digital)–> LCD
So if you plan on using TV Tuners to watch tv/cable or dvds on your LCD or CRT computer monitors, remember that even though the signal between the tuner and your monitor is digital, it is coming from an analog source and so the digital image can’t be better than it’s source. DVDs can be played in digital high definition ONLY if you hook your computer directly to your monitor and play the movie through your computer.
