I have tested both monitors on the DVI-I output on the video card and they work when plugged in there, but when I plug into the DVI-D port then the monitors do not show anything, just a red light. I have tested both cables and they both work on the top port, so I am assuming its something with the video card not outputting probably on the DVI-D output port.
I talked to EVGA Support and they said to buy a GTX 570 instead that has dual DVI-I ports and that should work. Does this seem right?


evga is incorrect. Does the monitors work with just 1 plugged into dvi-d? I have mine running on -i and -d on my 670s

I've been following this thread and just received my Crossover today. I purchased the 2720MDP GOLD on Sep 27 from accessorieswhole. The monitor arrived well packed and wrapped in bubble wrap like others have experienced. Mine also has the single HDMI port, and an open hole in place of a second. I don't think it's a huge deal, since I don't need both.

When powering on the monitor makes a humm then a little pop. Hopefully that's nothing to worry about. The pop sounds like it may be the speakers, though I'm not using them, and have nothing plugged into the audio input. I checked the panel close and couldn't find a single dead or stuck pixel. I got the MDP so I could use it on PC as well as a secondary display for my 27" iMac. Today I discovered my monoprice mini display port > hdmi adpator only supports up to 1080p, so I plan to grab a mini display port > regular display port cable and use the DP input for the iMac. My PC is using DVI. The screen looks great, and is definitely comparable to the iMac. For the price it's an awesome deal.

The stock stand wasn't bad at all. It was fairly sturdy. I had ordered a new stand that supported height adjustment and rotating the screen so I swapped that stand on after my initial test.(link)




I used another PC power cable, instead of the included power cable with the adapter.


My ports, with the missing HDMI.


First power on.


First comparison with the iMac.


No dead pixels.


Stand comparison, on the left is the 3M , and right is stock (non-pivot).


The 3M's mounting panel is slimmer than the stock one, so I used the stock back plate and the stock screws. The stand works well, now I can adjust height, tilt, and orientation (landscape/portrait).



3M stand Rotated.


3M stand height aligned to iMac.

I took off the back case and sure enough, the mofset looks to be burned up

I emailed accessorieswhole.. in the meantime have we figured out the cause yet?

Even if she sends me a new board, if I just burn that one up too i'll be very sad =/

what color PCB do you have?

Yo, I'm considering buying one of these but had a few questions first. First, I have a HD 7950, which isn't technically on the compatibility list, but will it still work? I remember reading somewhere that if its not compatible it might turn on, but you probably won't be able to access the BIOS, which would be a deal breaker for me.

Also, is BigClothCraft generally considered to be one of the better sellers on ebay? If not who is.

Lastly, for people who game at 1440p, what has your experience been like? I'm worried about 1. ghosting/input latency and 2. the higher resolution destroying my framerate. Thanks!

Edit: On second thought, from reading through the past few pages I'm seeing a lot of horror stories lol. Is quality decreasing or are the monitors just proving to not be reliable?

I am considering to buy this CROSSOVER 3020MDP can some one give me some feedbacks about this monitor? I did not found any review


Only this video... http://27.1.16.135/video/100423635

Once the MOSFET has burned up your options are pretty limited. You'll have to either replace the whole board, which is the easier of the two, or replace just the mosfet, which requires some tricky soldering.

From my experience so far, it looks like this is just an issue of the American voltage putting additional stress on the MOSFET. After trying a bunch of stuff and doing some reading, you have a couple options for protecting your new MOSFET that seem to have been effective for me. Quick background, my MOSFET also burned up and the backlight failed completely, my eBay seller (Red-cap) sent me a replacement PCB (unfortunately another teal one), which I installed. After about 2 hours of use I started getting flickering again with the new MOSFET so I decided to change stuff around since it was clearly overheating again. Your options are:

1. Install a heatsink on the offending MOSFET. This will help mitigate some of the heat, but usually isn't enough on its own. Newegg has a 10 pack of MOSFET heatsinks that fit nicely and do a decent job.

2. Run the monitor on American voltage through a really good surge protector and UPS that is going to clean/regulate the voltage coming in. (This actually was the first thing that gave me positive results and stopped the flickering even at maximum brightness, though it was with a heatsink installed as well)

3. Obtain and use a voltage converter to run the monitor at its native/intended voltage.

Currently I'm using method 1 and 2 and it seems to have been enough to mitigate the problem (just the heatsink by itself was still giving me flickering). I have ordered a voltage converter and will be adding that to the mix, as people have reported overall lower temperatures in both the monitor and the brick using the native voltage. When choosing a voltage converter make sure you get something that can handle the monitor. At max brightness the monitor uses ~100W, so a 200W one gives you lots of room. The final option of course is to contact your seller on eBay and request the green-colored PCB that doesn't have these issues. Maybe you'll get lucky and get one of those. I think either way though, its probably a good idea to regulate the voltage going in to these monitors since the components seem to be pretty picky.

UPDATE: 200W voltage converter has not yet arrived, but flickering has resumed on the monitor despite the heatsink and surge/UPS. It's gonna remain disconnected until the converter gets here frown.gif

Tehpsyc, sound analysis. I have a green PCB with 3 mosfets (does that mean 3 phases of power? I think so...not an expert though). Still, I have been running it off of that 200W voltage transformer that I mentioned earlier. Corresponding to what you said, I have seen a noticeable drop in temperature on the mosfet surface and the included power brick surface.

Question though, what exactly did you have to tell red-cap for him to send you a replacement PCB?

my 5870 works fine, I assume the newer cards should work too.
