Revainrating 1 out of 5

Works as a last resort, but with significant limitations

I purchased two different HDMI to DisplayPort adapters from two different Revain vendors and encountered the same issue with both, and my subsequent conversations with the Vendors led to the conclusion that the problem I describe below is largely specific to this type of adapter in general, and not just these particular ones. So the same rating applies to both adapters. These adapters can come in handy in a pinch when you absolutely have to power a DisplayPort device and everything you have has an HDMI output - perhaps when you're using a laptop to give a presentation. on the big screen - but anyone expecting them to be the perfect long-term replacement for the standard HDMI-to-HDMI connection will be disappointed. HDMI to DisplayPort conversion is simply the remapping of one type of high-definition digital video connector to another. No, that is not so. Apparently, special built-in processing is required to convert the signal. Note #1 should be that all of these adapters I've found on Revain are explicitly described as *not* bi-directional (meaning they can only HDMI to DisplayPort, not DisplayPort to HDMI), which I feel is atypical for adapters . Note #2 was that these adapters appear to require a separate power supply as they typically have built in short drop cables to draw power from a nearby USB port. In my experience, this is also atypical for adapters. (Interestingly, during my product research, the opposite type of adapter (DisplayPort to HDMI) turned out to be *simple*, although I haven't tried it, so can't say for sure.) Hint #3 was when I stuck the adapter first into his graphics card, even without a monitor connected, the system recognized it as a normal display. Defining the cable/adapter as a discrete device was also a first for me, and it was an indication that this adapter is performing some sort of complex built-in emulation of an HDMI display while the computer sees it as such. But that's not the case. until I connected the monitor to the adapter, I realized that the product is not suitable for me. It seemed to work at first, but when the system tried to go into sleep mode and put the monitors to sleep, the monitor connected to the adapter would turn on and off every few seconds. Clearly a non-working arrangement. I contacted both sellers about this issue and after weeks of exchanging emails suggesting the problem could be anything from my computer to my graphics card to my monitor, I finally got a response from one of the sellers who would have cleared things up if only they had said so in the beginning. Because the adapters contain a converter chip, they basically don't supply enough current to power the connected monitor. - Economy mode. It doesn't make much sense to me, but it confirms what I've experienced. (Which is odd, especially since the adapter is already getting extra power from the USB port. Why isn't that enough?) Every configuration isn't necessarily guaranteed to cause the same problem I've been experiencing, which seems pretty serious due to the limitations of the Adapter designs so this should have been clearly stated in the product description. I have forwarded this review to both sellers, but due to a customer service oversight, downgrading a two star rating to one star, received no response from either. If this limitation were noted in the description, I would understand. The adapters would most likely not suit my needs and I would not buy them. I should probably return both, but I have a habit of clinging to random A/V adapters that can come in handy in some situations. My final decision was to ditch those adapters altogether and buy another monitor that supports HDMI natively, and the adapters are now included in the box. Luckily I found a new monitor with the features I wanted at a good price. This may not be an option for everyone, especially those who buy these adapters and believe they will allow them to reuse their existing display without having to buy a new one. Product descriptions are missing important information, which is misleading. And the moral of the story is that if you're trying to use the HDMI output, you'd best forget the adapters and plug it into a device that natively supports HDMI.
