content: I need some recommendation on display port to DVI adapter. My computer used to have display port out and my monitors only have DVI. I bought some adapter and they worked but didn't allow the calibration sofware to communicate to the monitors for hardware calibration. I returned them and got some different ones and they worked fine. After that I upgrade to another video card which has DVI out so I put the adapter away. Now I am going to upgrade still to another video card and this new one only has display ports. But I couldn't find the adapters anywhere. So I want to buy a couple but how do I know that they would surely work. I hate to buy and return. Not good for me and not good for the store and driving cost up for all of us.

content: I'm using old HDMI to DVI adapter which was in the box with old nvidia GPU. Works good.I also tried these Chinese cables with HDMI on one side and DVI on the other, but it appears that some wires are missing inside the cable. As a result, it can't detect sleep mode, and the display shows a "Check display cable" error instead of entering sleep mode. It works in normal mode, but it's unusable for me because I need sleep mode - I don't want my display to stay powered on 24/7 when I'm not using it.So, I suggest to use adapters instead of cables.Technically, HDMI is just a newer version of DVI, so such an adapter doesn't require any electronics and power supply and there are no issues with video modes - but it's important that all necessary wires are connected.Regarding display port, I don't have experience with it, but you can try to find some display port->hdmi adapters on aliexpress.

content: Any old adapter should do, just make sure it converts in the direction you want it to. I don't know if they are typically bi-directional.

content: There are two basic types of these adapters, passive and active. The passive type depends on the source being able to send DVI signals over the display port and acts only to map the DVI output connector to the appropriate pins on the display port. I think this type would likely allow the kind of communication between display and computer that you need. The other type of adapter is active. The computer sends display port encoded video, and adapter decodes this and generates the DVI video signal for the display. I think this type would be more likely to block the communication.

content: normally you have to check if the DVI is analog or digital, the flat bar pin with 4 surrounding pins passive or active is somewhat confusing and again they are called single link or dual linkmany monitors accept both, some not, you may need the good one(s)
