A Bit More on the Topic About Active DisplayPort to DVI Adapters

March 21st, 2011 · 4 Comments · General 3D News


Here is an interesting find that I’ve stumbled upon today, an Active DisplayPort to DVI adapter from Sapphire. The interesting thing here is that the adapter is Active, but does not have an additional USB power cable, but if you are paying enough attention you should note that this adapter is providing just a Single Link DVI output. The adapter is originally intended to be used with AMD/ATI video cards fro providing video connection to more common monitors that are not using DisplayPort if you want to built a multi-monitor configuration based on AMD’s EyeFinity technology. This adapter however is not something that will work with a 3D Full HD monitor if your desktop or laptop has only DisplayPort output with the reason being that the output is not the Dual-Link DVI that is required to be able to push 1920×1080 video at 120Hz to the monitor. So you should be paying attention when choosing a DisplayPort to DVI adapter for use with a 3D monitor, you should look for an Active DisplayPort or mini DisplayPort to Dual-Link DVI adapter in order to make things work with high-resolution stereo 3D…

    I ran into this problem this weekend. I just got a AMD Radeon HD 6970. I wanted to check out Eyefinity but couldn’t use more than two monitors. I looked for an active display adapter at Bestbuy but they had no idea what I was talking about. I was about to order the Sapphire adapter today, but now I am weary because eventually I would like to hook up to 3, 3D monitors. I currently have an Acer GD235HZ that I use with my 480GTX with 3D Vision. I know that it isn’t compatible with the AMD 3d, but I am hoping new the Acer GN245HQ would be.

    I guess my real question is, What monitors can I get that would support 3D Vision, AMD’s HD3d with Eyefinity and I could play PS3 Games on.

    Dallas, you are asking for the impossible as AMD HD3D technology is not yet supported with the multi-monitor setups that the Eyefinity technology offers (at least not with active shutter glasses solutions), it is either one or the other, but not both together. If you want 3 monitors in a 3D setup then you would need to go for a 3D Vision Surround solution…

    Other than that any 3D-capable monitor with HDMI 1.4 and Dual-Link DVI supporting stereo 3D such as the upcoming Acer GN245HQ or Acer HN274H would do. These are 3D Vision Ready 120Hz monitors that should also work with AMD HD3D and with PS3 over the HDMI 1.4 interface.

    As for the Sapphire adapter, do have in mind that this is a DisplayPort adapter and not mini DisplayPort, so you should also check if your AMD/ATI-based video card uses the normal size or the smaller mini DisplayPort connectors should you decide to built an Eyefinity setup. If it is with mini DP, then you will need mini DisplayPort to DVI adapter…

    To be clear about this (and no one at Best Buy knows) to run 3 monitors in Eyevision you NEED an active, 2-way, miniDisplay Port to DVI adapter. If it doesn’t have a USB cable, it WILL NOT run 3 monitors off one card.

    If you don’t need 3 monitors the active adapter may (may) work.

    I have an ATI 5570 card (and a couple 5770s). On the 5570, I have 3 monitors: one on DVI; one on the active 2 way Sapphire miniGP to DVI; and one on the analogue D-sub 15 port.

    I also note that the graphics on the MiniGP adapter is limited in resolution from the ATI software.

    This is NOT optimal. I have another computer with dual 5770 GPUs for 3 monitors, and even then it stumbles.

    To compare I have a setup with 2 NVidia GTS 450s running 3 monitors with good performance.

    Have fun….

    Hi there, I am so glad I have stumbled across this I have been looking for ages about 3d with ati as LG have been very unhelpful.

    I have the lgw2363d monitor and a sapphire 6970.

    Am I right in thinking that all I need is a display port to dvi-d adapter, the iz3d drivers and some active shutter glasses and I will have a 3d system?

    I really hope this is so as I do not want to go with nvidia.

    Also, I have been told that any 3d shutter glasses will work with my setup and iz3d driver. Is this true?
