Guys, there's a very easy
way to solve handshaking issues. Here's is a step by step guide that you may follow.
LAST REVISION: 11/25/2009.This procedure will only work on Vista and Windows 7
. See here.
First of all, the OBJECTIVE: to force a .inf
file that will be the new monitor driver for the AVR HDMI display device.
So here are the steps:
1. DONWLOAD AND INSTALL MONINFO: get it from here
2.GET AVR EDID:
- - CONNECT THE GRAPHIC CARD TO HDAV 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, just connect directly from the graphic card HDMI out to the AVR.
- RUN MONINFO AND GET EDID 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->Create INF and SAVE TO AVR.inf.
3. OVERRIDE MONITOR DRIVER WITH MODIFIED AVR.inf
(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.
Of course you may use the name you like for AVR.inf (I use AVR-988.inf for my Denon 988 AVR).
That's it, you should be free now of any more handshake issues. Enjoy!
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.
