Zotac to release Passive DisplayPort/Mini-Displayport to 2 x HDMI Adapter

[Haldi]

So the Problem was the long mDP to DP cable?
Are there any difference in a Dp1.0 and DP1.2 port on the Hardware side? And if yes, are there dp1.1 and dp1.2 cables?

Yep, it was the 3' length on the mDP cable that cause drop-out. Not enough power was being pushed through it to power the adapter apparently.

Port and cable specs are so ambiguous anymore. It's hard to get a straight answer even from the manufacturers themselves. HDMI tends to be the worst offender though.

Just to update, this works perfectly on the Mac Book Pro, though it appears as a mirror screen by default (easy to disable in Display Properties).
Im using it with 2x HDMI to DVI adapters and 2 old Dell DVI monitors. Appears as one big screen on the Mac and onboard LCD works too.

Hello everyone.

I have a doubt about the use of zotac adapters on AMD eyefinity cards: What happend with bezel compensation between the screens plugged to those adapters? AFAIK The zotac adapters simulate one screen using two fisical ones; its that right? So, how you use the bezel compensation in this "virtual" screen created by the adapter?

Many thxs in advance!!

I use projectors so bezels are a non-issue. You are right though as half the bezels would not be able to be corrected.

hi can someone help me here.

i have 2x displays and i would like to use both as individual screens for my macbook pro 15 early 2011 model.
im not sure if the zotac mini display port adapter only mirrors the screens or you can use as individual screens.

thanks for the reply

It spans them for dual screen resolutions and mirrors for single screen. For example, 1920x1080 would mirror the screens while 3840x1080 would span. On spanning resolution it treats the two display span as one wide pseudo-display. Think of it as a cost effective Matrox DH2G box.

What if you connect two of these adapters? Would it be possible to create a 5760x1080 display?

Technically speaking, you could do up to 2x1L 3840x1080 (7680x1080) on the 5870 E6 and up to 4x1L 3840x1080 (15360x1080) on the 6970 DCII and 7970 DCII.

Only if the displays are 1440x1080. 5760/4=1440. You're symmetrically spanning two symmetrical spans by mixing these adapters and Eyefinity.

Thx a lot for the illustrated answer (+rep)! Now i understand the functionality.
It's a pity that the two outputs can't be used to adress two monitors separately.

I was planning to change my config from two rigs (6870E6 Monitors: 3x1/1/1 + 5770 Monitors: 3x1) to one rig (3/3/1/1), but this won't be possible with these adaptors except I can live with some sort of cutback.

I have done exactly as Brad shows, albeit with 4 units... I have made a 4x2 screen array (2x2 eyefinity group) and can confirm that these units work very well under Eyefinity.

I wanted to call some attention to another notable difference between this and a DH2G...the signal power. Just as Brad had issue with a standard 3' cable...I had issues getting these going as well.

I had to feed (quality 22AWG) 25' DVI cables...that worked perfectly in UXGA res off of every passive or active adapter I had. These Zotacs wouldn't even THINK about it. I had NO interest in replacing 8x25' cables. I had to buy the venerable Monoprice equalizers in order to get them to get the signal that far. At ~$30 each, 8 of them (and short HDMI jumpers) ended up being an extra $250ish that I was NOT happy about.

Granted, if you have short cable runs, this likely isn't a problem, but if your runs are long like mine, the deal might not be much better than a DH2G, which in my experience has powered DVI outputs and can deal with 25' cables fine, as well as the flexibility of the management software. Each Zotac (with the required equalizers/adapters) cost me ~$100ish, which is within the range of what DH2G can be picked up for on eBay (~$120ish).

Now I have a garbled mess of adapters:

Mini-Dp--------->Zotac--------->HDMI Jumper--------->Equalizer---------->HDMI-DVI Adapter----------->DVI Cable
.......................................--------->HDMI Jumper--------->Equalizer---------->HDMI-DVI Adapter----------->DVI Cable

When the DH2G would eliminate most all of that (granted, for HDMI instead of DVI, another adapter might be needed):

Mini-Dp--------->DH2G----------->DVI Cable
.......................................----------->DVI Cable


Moral of the story....if you have long cables, this *might* not be the droids you're looking for.
