Has anyone here managed to get the XB360 working using a monitor with a standard (full size) Displayport connection?
My new Dell U2412M monitor has DVI-D(HDMI compatible), VGA and Displayport but no HDMI. The DVI-D works perfectly with a HDMI > DVI-D adapter cable, the VGA works fine but I just can't get the Displayport working with the XB360.
All the information I have found online suggests all you need is a Displayport > HDMI adapter but when using one these the XB360 reacts like it's not connected to a monitor ie. it's not recognising the connection. The monitor recognises the Displayport > HDMI dongle is fitted, although that might just be a physical report. Whilst it indicates there is nothing wrong with the Displayport I don't have any Displayport capable devices to be certain of this 100%.
However, as I know the HDMI cables I've tried are good and the XB360's HDMI output is good that otherwise leaves just two possibilities:-
1). HDMI(F) > Displayport(M) adapter is faulty.
2). There's some form of incompatibility going on with the adapter.
The adapter is meant to have a small conversion chip built in. What I am thinking is that this is not bi-directional. I have found one Amazon seller warning about non-bi-directionality with their adapter but nowhere else.
That also suggests that somewhere somebody should be selling a HDMI > Displayport monitor adapter rather than the Displayport > HDMI monitor one I bought. But no seller I've found is making the distinction whatever they're selling.
Any help/suggestions appreciated.
Try Dell UltraSharp U2312HM. It has better features for IPS. One more thing, Diplayports are not substitutes for HDMI. It can only improve the system but its HDMI cannot be replaced. If it doesn't work, try to buy a <a href="http://www.squidoo.com/best-displayport-monitor">new displayport monitor</a> for the appropriate gadget.
