בחום על חיבור DVI בלבד:

Input Type: DVI, DVI, DVI. We insist that when you buy a new LCD monitor, you buy a model with DVI capability. Even if you don't want to buy a DVI-capable video card right now, it is still a wise decision to get a DVI-compatible LCD. When DVI first appeared in the industry, there were a few issues with the quality of the connectors and thus, sometimes viewing a signal over a DVI connector would give you a worse signal than over a 15-pin D-Sub connector. However, in the last 3 or 4 years, most of those problems have been fixed, and virtually every new video card is more than capable of producing a clean digital signal. None of the LCDs that we review today (except the Samsung 910V) are limited to only analog connectors, but be aware that they exist.

כלומר זה לא רק שגעון שלי :-), מסכים דיגיטליים צריכים לעבוד עם חיבור דיגיטלי,
אם לוקחים בחשבון שיש מתאם לחיבור אנלוגי לא צריך להיות ספק או חשש.
