HDMI + GTX460 Issue with Corrupt Screen in during gameplay.

[Attic]

I'm going to post information and a breakdown of the issue first, and then just some general questions about the 460 later. I'm using 258.96's.

I get pixelation/image corruption using the HDMI output when a game loads full screen. Non gaming, DVI or VGA connection, or window mode w/ HDMI resolves the issue. I'm hoping some other users have the 460 using HDMI and can comment.

TV: Sony Bravia 46" KDL-46EX400
Display Area: Full Pixel
GPU: EVGA SC GTX460 763/1526/1900 (no voltage or OC's beyond cards shipping bios) Temps ~80C during 1hr+ gaming session with 95%+GPU load.

EVGA Artifact Scanner finds 0 artifacts after 10 minutes using HDMI, full screen and window.

Using a DVI-VGA adapter and running FullScreen at 3D speeds there is no issue, same goes for DVI-HDMI cable.

Using Mini HDMI to HDMI adapter and then HDMI to the tele I have no issues unless I run a game full screen. Movie playback using adaptive clocks is fine.

Anyone else using HDMI can comment? The only other issue I saw that matched what I see was from another user who had the same TV. I thought I had this fixed, but my fix causes me to lose audio on HDMI. I'm adding a binary value to the registry causes the nVidia drivers to think i'm running DVI output, Control Panel confirms it works and the issue is gone in full screen gaming with HDMI using the work around.

My other question involves what temps are safe for the card and what to do about overclocking the GDDR5. With the Mem overclock i've read that pushing two far will not cause the card to artifact, but rather just drop performance. Is it better to push the Core as high as possible before messing with a mem OC on the 460's or does the mem bandwith need to scale with a core OC for an optimal OC on the card?

Overclocked should still be 70c. 80c seems pretty high, did you check fan durng gaming?

I ask because maybe it needs to be cranked up. I left my fan on auto on that card and never went over 70c. The fan would kick up to 50-55% on my EVGA GTX 460 SC.

It is on the high end of what I've seen as far as temps go for the card. The fan goes to 60% at ~80C while gaming. Loud, but at least it's dumping the hot air out of my case. The external exhaust 460's are a bit louder than the ones that lack that quality from what i've read. I also have a slim 120mm fan blowing onto the shroud of the 460, without the 120mm my temps were 86-88C. I run the card in a HTPC and, i've got good airflow, but case gets hot... it's on the smaller end of HTPC cases that fit full height expansion cards and it's also running a Q6600@3ghz, a hot chip. Lian Li's got a good HTPC case that i may upgrade too, espeically since i'd like to go SLI.

I would try it in another PC with HDMI, it might just be a faulty card. Lots of GTX 460 have to be RMA for odd issuses. Mine was random lock ups all the time.

I returned a Palit that exhibited the same behavior. With the nonsense with Palit prepping certain cards to reviewers and then sticking consumers with something different I was on the path of thinking the card was faulty so I returned it. Turns out the Palit card was actually fine from what I can tell and I had to pay more for the EVGA. With both cards exhibiting the same behavior I think it is something to do with how the driver is handling things.

I'm just hoping it gets fixed. I should contact an nVidia rep or maybe someone from EVGA to make sure it's a known issue, but I was hoping others with the 460 using HDMI could comment. Since the only other similiar issue i've read about has been with my exact same HDTV, it may be something i'm just unlucky with.

Edit: I should try out another system like you suggested. I am upgrading my other system running a 4830, I may pull my HTPC out and do some more troubleshooting on a different monitor in a different system.

Hoping to bump this thread up to see if anyone has some updated info.

I'm experiencing the same problems running an evga 460 1gb with the 266.58 nvidia drivers via mini hdmi to hdmi cable to... You guessed it... A Sony Bravia KDL-32EX400.

I tried digging through the Sony tech forums to see if there were any others experiencing this but no luck. I found a firmware upgrade for the tv (takes stock v1.11 to v1.512) but the USB key I had around to try the update wasn't satisfying the tv.

I agree it seems like an issue that could be fixed in the nvidia drivers, but it is concerning that the only sign of this problem is with the Sony ex400 series. Could Sony really have dropped the ball that badly?

I can confirm the same problem on my Sony EX500 series television with my GTX460 video card.

Incredibly frustrating since the pixelation only occurs when in full screen mode. It makes no sense.

I have not tried upgrading my tv firmware yet.

Any updates on this?

I can also confirm I'm experiencing the same issue - Sony 60EX500, Gigabyte GTX460SE via DVI -> HDMI cable; nvidia 266.58 drivers.

At some point I'm pretty sure I had thought I resolved this by disabling HDMI audio pass through but some how this issue has returned

Grrr.

I have a z-series from a couple of years ago...

Worked fine with one HDMI cable, but occasionally need to switch the resolution from 1080p to 1080i then back again.

recently purchased a longer (50') and cheaper cable. with this cable it only works in 1080i

Solved. Figured this out somehow but never came back to post my findings.

Under the NVIDIA Control Panel > Display -> Adjust desktop color settings > 3. Apply the following enhancements: ensure "Content type reported to the display:" is set to "Desktop programs". It's set to default to "Auto-select" which does not play nice with Sony TVs for some reason. I believe this is only something that happens with Sony TVs and this particular video card.

Note: This option is only available if your TV is setup as a display.
