Ik heb recentelijk problemen gehad met het tot stand brengen van HDMI handshakes tussen mijn home entertainment componenten.

Tot dusver ziet het er naar uit dat moninfo.exe de oplossing is en het EDID pad continue goed weet op te zetten. Ik kan nu zelfs tussen bronnen schakelen en toch steeds weer beeld en geluid terug krijgen. Ook maakt het niet meer uit in welke volgorde ik de verschillende componenten aan zet.

De procedure om moninfo te gebruiken heb ik van avsforum en zal ik hieronder weergeven voor al de mensen die er ook problemen mee hebben. Is in het Engels maar dat zal voor de meeste van ons geen probleem zijn.

METHODE

Guys, there's a very easy way to solve handshaking issues. Here's is a step by step guide that you may follow.

This procedure will only work on Vista and Windows 7. See here.

First of all, the OBJECTIVE: to create a .inf file that will be the new monitor driver for the AVR HDMI display device, with the custom EDID made up by:

- A first block with the EDID of the display device.

- An extended EDID block with the AVR audio capabilities.

So here are the steps:

1. DONWLOAD AND INSTALL MONINFO: get it from here.

2. GET DISPLAY DEVICE EDID:

- CONNECT GRAPHIC ADAPTER DIRECTLY TO THE DISPLAY DEVICE HDMI IN.

- RUN MONINFO TO GET DISPLAY DEVICE EDID: just look for the "Real-time] selection at the top left in the "Display IDs" windows. In my case it's a SAMSUNG, so I look for a display device with that name.

- SELECT File->Create INF and SAVE THE DISPLAY.inf FILE TO HD (save it to a directory where it will be THE ONLY .inf file).

3. GET AVR EXTENDED EDID BLOCK:
- CONNECT THE GRAPHIC CARD TO ASUS HDAV XONAR HDMI-IN AND HDMI-OUT TO AVR, as usual (for non-HDAV users just connect from GRAPHIC CARD TO AVR). If you can't handshake the HDAV with the AVR or if you don't own a HDAV, just connect directly from the graphic card HDMI out to the AVR.

- RUN MONINFO TO GET EXTENDED EDID BLOCK FROM AVR: in my case it's a DENON 988. So I look for first entry in Display IDs window with the tag "DENON-AVAMP" and "[Real time ...].

- SELECT File->Merge extension bloc with INF and SAVE TO DISPLAY.inf you saved in Step #2.

4. OVERRIDE MONITOR DRIVER WITH MODIFIED DISPLAY.inf FILE:
(I will show the procedure for 2 monitors, but works just the same for one. Procedure is for Windows 7)

- Right click on desktop and select "Personalize".

- Click on Display->Change display settings.

- Now click on the Screen of the AVR display.

- Click on "Advanced settings"

- Select Monitor Tab and click on "Properties".

- Select Driver Tab and click on "Update Driver"

- Select "Browse my computer for driver updates".

- Select "Let me pick from a list of drivers on my computer".

- Click on "Have Disk".

- Click on "Browse".

- Navigate to directory with the display device .inf file (Note: just in case, make sure that it's THE ONLY .inf file in that directory).

- Click on Open, OK, and install the new driver.

- Reboot.

Of course you may use the name you like for DISPLAY.inf and AVR.inf (I use SAMSUNG.inf and DENON.inf for my Samsung LCD and Denon 988 AVR respectively).

That's it, you should be free now of any more handshake issues. Enjoy!

PS:

If after applying the EDID Override you still have occasional handshake issues (especially with an ATI card):

1. Try with different drivers (latest > Cat 9.7 for ATI work best for me with a 4670 on Win7 x64).

2. Try reproducing the problem, go to Device Manager (Start->Computer, right click on Properties) and see if the EDID override driver is in fact selected under "Monitors". If not, then do the EDID override again there by updating the driver for the corresponding monitor to your DISPLAY.inf (see step 4 above).

Then reboot and try to reproduce the problem. As long as the EDID override driver is automatically selected by Windows you should not have any handshake problem.

Vanwaar een heel nieuw topic openen als je gewoon in je oude topic verder kan gaan. Geen reden voor dubbele topics of om iets twee maal onder de aandacht te brengen...

Some people just need a high-five.... In the face.... With a chair.
