Alienware m17x R4 hdmi / HD TV Samsung problem

I have recently bought a new m17x r4 and i have problems with it while connecting my TV via hdmi. It sees my TV in CCC (radeon 7970m GPU) and at first i can see my desktop/movie on my TV but then it suddenly says that there is no signal, and i thought that maybe it has some thing to do with the hdmi cable but thats not the case because my acer laptop works with no problem.
I tried changing resolution,refresh rate, and still doesn't work. The first time i insert the cable i can see the imagine on the TV then suddenly dissapears whit some strange colors.At a time is said that the mode i use is un-usable
Any idea if its the HDMI output faulty or is it software problem? (driver etc) and btw i reinstalled the driver twice
(i run it without enduro)

 

I know you said it wasn't the HDMI cable, but it sounds like it might be. Try a different cable. Also what does the laptop do when this failing of the television happens?

 

the laptop works perfectly normal, like nothing happens, only the TV is not showing anything

 

Press windows button + p, probably havent set it to send out signal to tv, maybe jsut on laptop monitor only.

 

no thats not it, i did some change in catalyst control panel and now it works for a limited time then suddenly says no signal but if i stop and start the TV again it works

 

maybe try a different hdmi port if it has more than one

 

tried even that and no luck

 

no more ideas? i'm desperate in making it work

 

do you have any other cable than hdmi?
display port? vga?
try using that

 

What settings are your output at?
Have you set it to definitely duplicate your laptop display to your external display?

I assume that some tv's don't like certain refresh rates at 1080p. 60hz should work but not guaranteed, try 24hz see if you can at least see an image.

 

If you have tried another HDMI cable then try connecting via VGA since it is not a digital signal. If that doesn't work look online for your television accepted resolution. Then change your resolution to one that it accepts, It may seem simple but this happens with some televisions.

 

yah i tried on VGA and everthing is normal

 

on my other laptop i use 1080p with 60hz refresh rate and yes i use dublicate setting display

 

What drivers you running? Sounds like an issue with the connection, I have an nvidia gpu, so I couldn't check the control panel since they're not the same.

 

now i'm using latest amd driver (thats 12.11beta), the one from dell its the same and the latest stable 12.10 also nothing changes(except from games that stop working)

 

Could you try enabling enduro? Sounds weird but if the integrated graphics can output an image you can rule out the problem with the cable and port on your laptop and must be an driver issue.

Does the CCC detect your tv? Like can it read the model number, it should be able to, or you might try disbaling it, might be conflicting and causing the display to drop. Like when I connect my hdtv to my laptop it will see a kind of model of the tv and auto adjust the settings for me.

 

i enabled enduro and yah it seems to somehow repair the problem although i don't know what this has to do with the hdmi.
thank you very much for your help i appreciate it
