Club 3D CAC-1010 DisplayPort to DVI Dual-Link DVI-D Active Adapter for Your Monitor/Display - USB A Powered – 2560x1600 Resolution HDCP Supported NOT for Apple Cinema Monitors, Black

Works

+ Works with Korean overclocked monitorsI have a couple of 1440p overclocked monitors (only gone up to 96 hz). They have been consistently hard to use with newer GPUs since they are DVI-only. Basic adapters are single-link and don't work. But these powered dual link adapters work at the overclocked refresh rate. I'm supplying USB power thru a powered USB hub (power only ports).The only quirky thing is the adapters take a few seconds to come up after they receive power / video signal. During that time they cycle thru solid primary colors. The flash of white light sometimes startles me at night when it wakes up to update or backup.(For those unaware, there was a period of time where high quality factory second panels were sold to smaller manufacturers, commonly in Korea. These mfgs would pair the panels with cheap DVI controllers that more-or-less directly wired the signal to the panels. Which meant that you could just set a custom display resolution with higher refresh rate and it would just work up to a point. 96 hz was generally safe, but above that could work with some color calibration. They were also a bargain, price-wise. These kinds of monitors were commonly referred to as Korean overclocked monitors.)

I parted with my Mac tower but couldn't part with my massive display. I got this to attach to my Nvidia Quadro m2000 on a HP Elitedesk 800 g1 tower. Works perfectly.

UPDATE 6/27/23: Seems to get worse over time. Now it syncs up properly less than half of the time, requiring multiple reboots or cable reseatings to get the HDCP to sync up. I can't in good conscience recommend this product. It's a cheap substitute for a modern monitor and overpriced for what you get: an adapter that barely works most days, and adds black flickers when it does.For my older Acer GN246HL, it does what it needs to do: provide a dual link DVI signal for gaming at 144hz. Setup was simple enough and despite a slightly longer screen initialization time, it functions as it should for this purpose.The problems come with its other functionality. While on desktop, especially while watching video, there are occasional full screen blackouts that last maybe 1/4 second. Annoying and somewhat rare, but present nonetheless.The worst issue however is the HDCP. Despite buying the HDCP On version required to watch streaming video services, it works only about 80% of the time and is very finicky/flaky. In order to work at all, the monitor must be on and fully initialized before the computer is turned on, if this is reversed the HDCP will not sync up at all. Even when doing this correctly, it is possible for the HDCP to fail anyway, causing the whole screen to become fuzzy any time HDCP-enabled video is playing on screen. The only way to fix this in my case was to unplug the DVI cable from the adapter for a few seconds, then plug it back in, but I shouldn't have to climb behind my computer whenever this happens. I do have a spare HDMI cable I could switch to for HDCP video, but I shouldn't have to switch between inputs whenever I want to watch something, which is several times per day.What's really frustrating is that despite these issues, this might be the best quality product of its kind available for sale. All the other DP>DVI adapters review much worse, either not working at all or providing only Single Link compatibility, which is worthless for 144hz displays. It's disheartening that this is probably the best of limited options, despite being a buggy and inconsistent product.If I could have afforded to just buy a new 144hz monitor with DisplayPort, I would have done that instead of settling for this thing. I can only recommend it if you're in the same situation: needing an adapter for your older gaming display but without the funds to simply replace it with something newer. But if you have the cash, don't bother with this thing, you're better off with a new monitor instead.

Most important part first:Whenever I have HDCP content such as copyrighted images or video on ANY of my 3 monitors, the monitor using this adapter will become static-y for around 5-10 seconds. After that the monitor will return to normal. You can see what the monitor is displaying through the static, but it is annoying. It seems that the HDCP ON part kicks in after a delay. Otherwise, it works well.I've been using the HDCP ON version of this adapter on one of my side monitors for about 2 months now. I had to research what HDCP was before I bought this to ensure that I bought the right version of this product. I settled on getting HDCP ON because I wasn't quite sure what would happen if I got the wrong one. I found out the monitor gets static-y but you can still tell what's going on if you have to. I don't do a ton of streaming on my computer, but I have found that certain images, videos, or advertisements will make use of HDCP according to when my monitor using this adapter gets static-y. I play a lot of games on this computer and have not had the monitor become static-y with any of those. If you're wondering whether or not you need HDCP for games, it doesn't seem like you do? I haven't seen the monitor get static-y during games. I am not an authority on that though, so do your own research. This adapter has worked well otherwise. If you're planning on using this on your only or your primary monitor for a computer, be aware the screen may get blurry/static-y when viewing HDCP-protect content for a little bit.
