Ati radeon strange problem

I have this strange issue....i work on my pc,internet browsing,downloading etc,then i switch OFF the t.v. i go away and let the pc ON for downloads,and when i come back the pc is still on and running BUT when i switch ON the T.V. i have no signal/icon like someone removed the HDMI cable from the t.v.
So i press the reset button and everything is back to <<normal>> until the next time.
--------------------------------------------------------------------------------
Edit:i have the problem when i install the ati catalyst,when i completely remove catalyst/driver everything working fine.(I tried 10.10 10.11 10.12)
But this is not the solution because i need the catalyst installed for gaming and HD video.
Questions... is the microsoft driver (windows updates)capable for gaming and HD video watching?

try turning the tv on first then send the signal from the card through hdmi that is how i do it my tv won't allow me to just pop it up cause i changed resoulutions

You must first turn on selected monitor then proceed to the resolution change then the tv should reconize it right away with the tv off the card won't send a signal but when you have it on the card will know to send it or it'll just go back to the original monitor

I hope you understand where im going with this and also hope it helps you figure out you're problem

just stick with the 5670 or get a 5770 sorry didn't read you wanted a newer card lol

6850 is good too i use the 6870

5770 and the 5850 are the one's your card is modeled after

there are some reviews the 4890 especially in xfire is still faster than the 5670

yes any above mentioned card yes 100% compatible to your board you have pci -e 2.0 and multiple gpu support so if you want the hd6000 series then it will run on your board fine

AND WHY THE GRAPHIC CARD IS LOOSING THE SIGNAL WHEN I SWITCH OF/ON THE T.V.?

do you have any hibernation or sleep mode enabled also i did mention this issue in above post of the card loosing signal when turning off the flat panel tv

the only time it doesn't loose signal if you are changing chanels but for the most part that has happened to me if i dont set the tv to hdmi before swapping monitors it wont pick it up correctly if it isnt on that moment and when you shut it off i think you only broke the signal and would have to reset

I would just use a screen saver power mode and just let windows turn off the monitor that way you will still save power but can move the mouse to activate it

use the power plan feature make a custom plan that way windows can shut the monitor down for you and can walk away from downloads .....I hope this helps I don't think it is the card personaly unless it really has bad lines and black screens keeping display from being shown i think you're card is fine
