Weird 360 slim hdmi problem

Hello all,

Having a very strange issue with my 360 slim.

I have recently added a 4 x 2 hdmi matrix box which successfully receives output from a 360e and an xbox one and outputs it to both monitors (1 x Samsung, 1 x Iiyama)

If I plug the hdmi cable from the slim straight into both monitors I can get a picture from my older monitor (Samsung) which until recently was the one I always had the slim plugged into. The newer Iiyama displays nothing though something is getting through
as the monitor wakes up.

If I plug the hdmi cable from the slim into the hdmi matrix it refuses to display anything on either monitor.

I have tried clearing the cache on the slim which hasn't helped.

Any ideas? Is this possibly first symptoms of a wider problem developing with the slim?

Thanks in advance for any ideas / suggestions.

Tim.

:)

 

No More Video Output to Monitor

Hi.

I'm going to try and be as detailed as possible with this one. About to pull hair out.

----------------------------------------------------

Materials On-Hand:

Xbox 360 Slim (The Culprit)

Xbox 360 Pro with HDMI Output (Alternate Test Subject)

Laptop Computer with HDMI Output (Alternate Test Subject)

HDMI-HDMI Cable (Works Fine)

HDMI-DVI Cable (Works Fine)

Dell 2408WFP Monitor (Has DVI Port, HDMI Port, Composite Video Port)

Dell 2208WFPt Monitor (Has DVI Port)

40" Sony LCD TV (1080P Capable)

60" Sony LCD TV (1080P Capable)

----------------------------------------------------

History:

- For the past 7 months, I've had my Xbox 360 Slim connected to my Dell 2408WFP Monitor with an HDMI-HDMI Cable. No issues.

- A couple of weeks ago, I lent my xbox to a friend a couple doors away. He has a Dell 2208WFPt monitor, which does not have an HDMI Input. I gave him an HDMI-DVI cable to use, and it worked on the monitor with no issues.

- When I got my xbox back, it refuses to output a video signal to my Dell 2408WFP Monitor via HDMI-HDMI or HDMI-DVI. Nothing I do can get it to output to my monitor (which it was working fine with for the 7 months prior to me hooking it up via HDMI-DVI to
the Dell 2208WFPt).

----------------------------------------------------

Configurations Tested:

Xbox 360 Slim + HDMI-HDMI Cable + Dell 2408WFP Monitor = NO Video/Audio

Xbox 360 Slim + HDMI-DVI Cable + Dell 2408WFP Monitor =
NO Video/Audio

Laptop Computer + HDMI-HDMI Cable + Dell 2408WFP Monitor = Video GOOD (Proves that 2408WFP HDMI Port and HDMI-HDMI cable both work)

Laptop Computer + HDMI-DVI Cable + Dell 2408WFP Monitor =
Video GOOD (Proves that 2408WFP DVI Port and HDMI-DVI Cable both work)

Xbox 360 Pro (Borrowed from Friend) + HDMI-HDMI Cable + Dell 2408WFP Monitor =
Video/Audio GOOD

Xbox 360 Pro (Borrowed from Friend) + HDMI-DVI Cable + Dell 2408WFP Monitor =
Video/Audio GOOD

Xbox 360 Slim + HDMI-DVI Cable + Dell 2208WFPt Monitor =
Video GOOD (Proves that Xbox 360 Slim still outputs DVI Signal OK)

Xbox 360 Slim + HDMI-HDMI Cable + 40" Sony LCD TV =
Video/Audio GOOD (Proves that Xbox 360 Slim still outputs HDMI Signal OK)

Xbox 360 Slim + HDMI-HDMI Cable + 60" Sony LCD TV = Video/Audio GOOD

----------------------------------------------------

Troubleshooting Options Attempted:

Factory-Reset Dell 2408WFP Monitor

Turning Display Discovery Off

Turning Display Discovery On

Attempting to Reset Display Settings with Right-Trigger + "Y" Button upon Boot

Hooking Xbox 360 Slim up to Dell 2208WFPt monitor, setting a lower resolution, and hot-swapping to Dell 2408WFP monitor (Both HDMI-HDMI and HDMI-DVI Cables)

"Blindly" Navigating Menus while hooked up to Dell 2408 WFP monitor (HDMI-HDMI and HDMI-DVI) to modify Display Discovery settings and selected resolutions

Hot-Swapping between Xbox 360 Pro (Borrowed from Friend) and
Xbox 360 Slim

Hot-Swapping between Laptop Computer and
Xbox 360 Slim (HDMI-HDMI and HDMI-DVI cables)

----------------------------------------------------

With all of the above, my Dell 2408WFP Monitor immediately goes into Power-Save Mode when the
Xbox 360 Slim is hooked up to it. The monitor works with another xbox, a laptop, and via multiple cables. Therefore I know that the ports are good, the cables are good, and the monitor is good.... but it refuses
to display anything from my particular Xbox 360 Slim. Ever since being hooked up to the Dell 2208WFPt monitor via HDMI-DVI, it simply will not work with the Dell 2408WFP Monitor. I cannot think of any other options.
The Xbox 360 Slim works fine on any other display I try it on. Another Xbox works fine on the Dell 2408WFP Monitor with both the HDMI-HDMI and HDMI-DVI cables. As a reminder, the
Xbox 360 Slim worked just fine with the Dell 2408WFP monitor for 7 months via the HDMI-HDMI cable.

I appreciate any assistance that can be provided. I don't know what else to do. It's very mysterious. Thanks.

 

No More Video Output to Monitor

Already tried that (was listed in my original post). The HDMI-HDMI and HDMI-DVI cables both work, and my HDMI-HDMI cable is the same one that was used for the past 7 months when I wasn't having this problem.

I believe this may be a software issue within the Xbox 360 Slim.

 

Hey mate, it's really hard to say, but if you've plugged the 360 into other TV/Monitors and it works, I would say it's the monitors, HDMI matrix or the cables your are using that are on the way out.

There is of course the possibility that the console display settings are only optimal for the one monitor and not the other and I would suggest playing around with the consoles settings to see if you can get a picture to display that way:
