very easy way to solve handshaking issues. Here's is a step by step guide that you may follow.
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. CONNECT HTPC DIRECTLY TO THE DISPLAY DEVICE.
3. 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.
4. SELECT File->Create INF. SAVE THE
DISPLAY.inf FILE TO HD (save it to a directory where it will be THE ONLY .inf file.
5. CONNECT THE DISPLAY DEVICE TO HDAV HDMI-IN AND HDMI-OUT TO AVR, as usual.
6. 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 ...].
7. SELECT File->Create INF. SAVE TO
AVR .inf .
8. EDIT
AVR.inf WITH NOTEPAD:
- Open Windows Explorer and browse to where you saved your
AVR.inf.
- Right-click on it, select "Open with", choose Notepad.
- Search for a line that begins with:
HKR,EDID_OVERRIDE,"1" ...
- Copy the whole line to clipboard.
9. EDIT
DISPLAY.inf WITH NOTEPAD:
- Search for a line that begins with:
HKR,EDID_OVERRIDE,"0" ...
- Paste clipboard to a new line just after it.
- Save file.
10. 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.
That's it, you're free now of any more handshake issues. Enjoy!
