 |
|
I was trying to get to a resolution that would allow Nvidia Vision 3D glasses to work by setting up a resolution in Powerstrip for 1920x1080p@96hz while using IFB HDMI input 2. When I tried it I just got a black screen. Since then HDMI input 2 will not work with a PC signal but will accept HDMI from the satellite box, but the colors are pink/green unless I hit 5 on the remote. After settting the PC back to 1080p@59hz, it will work in input 1 but not input 2 at all and input 2 doesn't seem to select the colorspace automatically anymore. So basically input 1 works fine but input 2 won't accept a PC HDMI and has colorspace problems.
Is there something that I can do to remedy this like a reset? Is it possible the 96hz did something?

Dear Jerry:
try press 4 to let card auto detect input color space.

Moome,
Pressing 4 while using HDMI input 2 makes the color green/pink. Also, if I connect a 1080p signal to input 2, the DET light stays dark but it lights if I connect 720p and I get an image.
Pressing 4 while using HDMI input 1 works correctly and the image is good for both 1080p and 720p signals.

what 1080P source you connect to input2? maybe the EDID content is overwrite
do you have pc software can check if input2 edid content is different from input1?

I actually tried PC 1080p@60 into input 2 and only get a blank screen and 'No Signal' message from the G90. Also the 'Det' LED on the moome card does not light up. If I simply move the same signal in HDMI input 1 and hit the select button, the PC 1080p signal comes shows great on that input and the Det. lights up. I suspect if I try PC 720p@60 into input 2, that may work.
What program can I use to have the PC read/write the EDID data on the moome card? I have a monitor on the video card's other output which would allow me to see what I'm doing with the PC while also connected to the projector's HDMI input 2 which currently shows no image on the G90. I know when I look at the multiple monitor setup, the IFB shows as 'NEC'. I need to check if it still says that or anything when the cable is connected to HDMI 2 but not showing an image.

After checking, I do not see any EDID in the nVidia control software when connected to HDMI 2 but I do when connected to HDMI 1. The LED next to the HDMI connector goes from green to yellow. Does this mean something in messed up for the EDID on that port? Can it be restored?

It might mean that port is not working. maybe a bad connection. I hate HDMI, it is not very durable if you remove the connector even just a few times it can break. Had this happen on a few TV's of friends. Trying to re solder the connections is a bitch!

Guys,
is 1920x1080P 96 Hz even in Moome's bandwidth limit ??
doesn't the card have 220 MHz Bandwidth?
above frequency is way over that.
only 1920x1080i 96 Hz might still work
I don't see any mention of 96 Hz working on any resolutions specified in the Specs.

Hi,
This is well possible. The EDID data is usually stored in a non-volatile memory (NVM) chip which communicates with the connected source. Depending on the design it could be a separate chip (usually a serial EEPROM with two-wire-bus, something like this: http://www.gs.ru/soft/si/SS1-15/24c16.pdf) or it could be incorporated into the HDMI receiver chip.
The Moome card acts as if it was the input section of a display with HDMI inputs. The source device will read the EDID data in order to determine the display's (aka Moome) capabilities and set its output format accordingly.
For some devices the EDID data can not only be read but written too. I have seen that with the HDFury (see http://dme.ghost2.net/forum/viewtopic.php?t=17726).
Maybe this is possible with the Moome card too, if the NVM isn't write protected (usually selected via one of the chip's pins tied to GND or VCC). You might as well use Powerstrip in order to at least read and compare the EDID data from the two inputs.
If You don't get it working again You could also use a small HDMI input switcher (lets say an automatic 3 to 1) and connect it to the good input...

PC software, you can check whether the INPUT2 the EDID content is different from the INPUT1?

As an update to this topic I now have both HDMI inputs working again after using a Gefen HDMI Detective. I don't claim to understand HOW this fixed it but this is what I did:
1. Connect Gefen to working Moome HDMI
2. Recorded EDID (pressed Gefen button, green LED went from blinking to solid)
3. Connected Gefen to non-functional Moome HDMI and HDMI source (expecting only that the recorded info on the Gefen would trick the source into handshaking).
4. Removed Gefen, plugging source HDMI into previously non-functional Moome HDMI. HDMI input then worked fine and PC reads as 'NEC CRT' (which is the same identity the working port gives)
So it seemed that the Gefen somehow restored the EDID info on the non-functional port.
