GTX 460 problem with hdmi

[eeliah]

heya! I got my new nvidia for few weeks now and it has worked well.. until i wanted to watch a movie via hdmi. If i extend desktops with my monitor (benq e2200hd) and tv (samsung le46a656) it works fine for few minutes. After that it starts to blank tv screen and stops audio too. Picture comes back and movie goes on.. Such a ***** problem really! Any suggestions? I've tried different mboard, different cables etc..

Q9550 @ default clock
GV-N460OC-1GI
corsair hx650W psu
and creative x-fi titanium gaming soundcard
abit ip35-e motherboard with latest bios (2008) i bricked my last motherboard with biosflash i thought that it would help but guess no

even if i disable creative soundcard picture is still blinking etc. help me plz so i can watch movies!

Hi and welcome to the Gigabyte Forum.

You dont say what case you have this installed in or what tempertures you are getting but it would sound to me like it was possibly temperature related.

What resolution are you trying to run when you have the problem.

What resolution are you trying to run when you have the problem.

my case is fractal design define R2 with 6 case fans and idle temp is something like 40c with gpu-z dont know exactly temps since it works nice with my benq monitor

And using native 1920x1080p with 60hz in tv.. both screens running natives

any suggestions? atleast some program to monitor temperatures.. HDMI cable is almost brand new and it worked with ati card atleast :/

noticed that display wont flash if im using 1080i with 30hz in tv.. what kind of problem that would be?

[Dark Mantis]

I don't have access to one of these graphics cards for testing purposes so I am purely guessing here. It could be an problem with the display not syncing with the output from the card properly. Can you check on the TV input settings and see if there is anything that might be manipulated.

The other thing I have just thought of is maybe it is something to do with the copyright protection. I am afraid this really isn't my field but hopefully it has given you something to go on.

it works how it should work with 1080i but image is kinda slow with 30hz, and im sure its not with the copyrights since trying to watch bought dvd or youtube videos or anything it starts blinking..

[Dark Mantis]

The thing is 1080i is only half the rate of 1080p as the i stands for interlaced and the p for progressive so you would need to send twice as much data to update the picture of the 1080p than the 1080i as it will only update every other scan.

noticed 1 other thing too, first my tv is hdcp capable and then its not -.- does hdcp mean something in nvidia language?

[Dark Mantis]

HDCP stands for Highbandwidth Digital Content Protection and is what I suggested a couple of posts ago but you dismissed it.

[eeliah]

so i can watch movie and youtube etc. with my Benq screen but hdmi out doesnt work even with wallpaper since HDCP? called to vendor of my card and they said that try to fix it yourself lol. so im getting 2 computers today to work with this nice touch of nvidia

[Dark Mantis]

I believe that HDCP only effects the HDMI output not the others. Let us know what happens today please.

too tired to try anymore but im using now same cable and mini adapter as i used my tv, now with my benq monitor and says that hdcp is not supported but picture doesnt flash and sound is working too via hdmi :O so it there something wrong with tv now or settings in nvidia controlpanel.. doesnt know rly i've putted in my opinion right settings for samsung le46a656 but :O

and sorry for spam but last 10mins with setup like Benq monitor in mini hdmi and tv is connected with dvi - hdmi cable.

Controlcenter says still that samsung tv doesnt support hdcp BUT video + sound works great.. So is the problem now in card or not? Im going to buy a long dvi - hdmi cable so my system works 100% for then no needs for rma

Sounds like a good way to go. Confusing, all this stuff though isn't it? As I explained at the outset it is not really my field but we learn as we go along.
