2407WFP HDTV problems
I purchased a 2407WFP widescreen LCD last month (end of August), and was able to successfully hook it up to my Time Warner (New York) HD cable box using an HDMI-DVI cable. The connection worked perfectly, and when the monitor was switched to the DVI input, the cable box detected the HDCP support and display an HD picture. For some reason yesterday this connection simply ceased to work. The cable box is no longer detecting the HDCP or the supported resoluction of the monitor (so the cable box is defaulting to full 1080i). When I try to switch the monitor to the DVI input I get the following message:
Out of signal range.
Can not display this video mode,
Change computer display input to 1920x1200 @ 60Hz
And my cable box now indicates that it's trying to send a 1080i signal. So it seems to me that the monitor is no longer sending the proper information to my cable box to tell it which resolutions it supports and that it supports HDCP. I've tried this with three different HD cable boxes (that all work with my larger TV), so I've pretty much ruled that out as the culprit.
Anyone have any idea what could be going on here?

Well, I think that's my problem - the box is attempting to display full 1080i, which the monitor won't support. Prior to this problem, however, I believe the box was detecting the resolutions supported by my monitor and down scaling the 1080i. Either that or the monitor was doing it. Either way, I was able to display all HD channels (both 1080i and 720p) via the DVI port. I have the A02 revision, BTW. I spoke to Dell for about 90 minutes yesterday, and they seemed pretty stumped (in fact I still don't think the tech support guy really had any idea what I was talking about). They're sending me a new monitor, which should hopefully fix the problem.Isn't the 2407WPD supposed to display all HD signals via the DVI port? That's one of the main reasons I purchased it.all the facts

My replacement monitor showed up today, and sure enough it's an A03. However, I'm still encountering the exact same problems. Has anyone else experienced anything like this?all the facts

As far as seeing the signal then not, HDCP is buggy on different setups, no matter what it is.
"I was able to display all HD channels (both 1080i and 720p) via the DVI port" I don't see why it won't do it now, but HDCP?
Cable box compatibility with 2407 A03?? Did you call your cable company and ask about monitors and is the cable company blocking certain devices, just a thought. I think HD cable boxes block certain recorders, but not the case here.
I don't have HD cable; I’ve seen mixed results here for no apparent reason. Recheck all connections and source recognition options in OSD. Not exactly what you wanted to hear, but trying.
Anyone else, HD New York Time Warner Cable thru DVI?
The chip in the 2407 won't do 1080P. Should or might do 1080I thru component and down res 1080P to 720P.

- Yes, I live in NY and have Time Warner cable's HD box. When connecting via DVI-D I get an out of range error from the 2407WFP and a no HDCP message from the cable box. I am able to run 1080i via component, but we will get back to that. If I was running dual displays and unplug the DVI cable from the cable box, the cable box error message goes away, so there may be two seperate issues here.
1) I've been told that the DVI-D port was meant for computers and has problems with cable boxes and such. I am using an A03 version, I believe, made on June '06.
2) Time Warner Cable may not have this montior in their HDCP logs
I was also told that due to a poor deinterlacer you will actually get a better picture on 720p then 1080i for component. Not that 720p is better than 1080i, but that for this monitor only the 1080i over component has problems. I hope this helps.

I’m actually surprised you were ever able to see 1080i over DVI on the Dell 2407WFP. What revision do you have?
On my A02 I was never able to get it to accept 1080i HD digital video signal over DVI or VGA (only over the Component inputs). For DVI and VGA I always got black screen with “out of range” message.
I was also unable to display a proper 720p image on the Dell 2407WFP over DVI or VGA. When feeding 720p over DVI the image is distorted (psychedelic colours), whereas over VGA it is off-centre (shifted to the left by about 1/3 of the screen).
