Cant Extend to Third Monitor By SAPPHIRE Radeon HD 5750

[Zentik]

Hello.

I am from Maldives. and I am trying to Extend to 3 HDTV's from my 3 displays with my SAPPHIRE Radeon HD 5750 1GB PCI-E Video Card.

But The problem is i cant extend to the third TV. the catalyst controler detects the three TV's but when i try to Extend the third one it tells me that i have to disable one TV to Enable the other one. and when i try to extend from windows properties it says that "Cant save the display settings".

I have upgraded all of my software's to the latest available.

and also i am using a DisplayPort to HDMI adapter beacause i have read that i have to use one TV on Display port to extend to the third monitor.

But Still Its not working. in all case i get the same result.

I am running Windows 7 64bit.

is there any Help or suggestions anyone can give to me..

PLEASE HELP

Thanks in advance.

Are you using an active DisplayPort adapter? A passive one will not work.

Please describe the physical connection you are using for each of your 3 HDTVs (DisplayPort, HDMI, VGA) including listing any adapters you are using.

You're using a passive adapter. That won't work if you want to use 3 screens.

From the Sapphire website "*To support 3 displays, one of the monitors has to support DisplayPort"
