Breaks down after only 4 months

Well. Actually, I was quite satisfied with the adapter. Makes a solid impression. Unfortunately, he has now - after only 4 months - made limp. Say no more. No, it is not on the computer or on the projector, because another adapter works. Very unfortunate. While he was with me, admittedly in continuous use but I've always treated him very carefully. Even with a low-cost model I would have liked a little more longevity.
