Despite the low price, it is a finely crafted materials and high quality. It allowed me to connect a former 1280x1024 screen with only a DVI input on a Raspberry only with an HDMI output. Since the adapter is of the "Integrated DVI" (DVI-I) with digital and analog signals and that my screen has a DVI-D digital input, I have 4 small tear C1 pin> C4 and introducing "in force" because the Adapter C5 blade is wider on a DVI-I as a DVI-D. No worries it's all very easy ... It's the price to pay at the stupidity of the "standards" that evolve incoherent! But with use, everything works perfectly.
