When connecting a PC to a monitor, are there any significant performance penalties when using the various types of monitor cables? e.g. Should I expect different performance between the following:
I know that the pure DVI cable is better because the computer doesn't have to translate the signal from analog to digital. But is that really of concern nowadays? | ||||

I can't see there being a performance hit as the converter is just modifying the signal coming out of the computer, and the signal processing is done in real-time. In a previous job dealing with real-time 3D graphics we made extensive use of extension cables and splitters and never noticed any performance issues (lag, reduced frame rate etc.). | ||||

No, this doesn't matter. The output of your graphic cards is always digital and is converted to plain old analogue vga by a "dumb" converter which has no influence to the rest of your pc. There's one thing to keep in mind: When using DVI-D to DVI-D on a HDCP (High-bandwidth Digital Content Protection) enabled monitor there may be an impact to the performance. You'll need an HDCP-enabled display to playback blu-ray etc., theres some encryption being applied to your output. | |||
