Problems with Nvidia Drivers

[Kamzu]

Hey guys, I'm new to the forum!

I recently built a new HTPC with the following specs.
Intel 4310T
Asus Z97M-Plus
Lian li PC-C37 Case
Rosewill Silentnight 500 watt PSU
16gb Crucial Ballistics low-profile RAM
Crucial 500gb m.2 SSD
Noctua NH-L9i Cooler
LG Blu-ray drive
GIGABYTE GV-N75TOC-2GL 750Ti Videocard

Seems like the new drivers 344.75 causes the computer to freeze when trying to watch live TV, the previous drivers 344.65 work fine but causes the dreaded 29/59 bug which seems to have been temporarily resolved by selecting "Content type reported to the display" to Full Screen. Has anyone have any experience with this card and is there a better work around? Does the new drivers work for you? Thanks!

There is a 344.82 and a .89 also, some adjustments that might help.......here.....

Are you also trying to play games on this system? The onboard video on that CPU would be more than enough for HTPC duty, including Blu-ray. Personally I'd go with the onboard and save the space and heat.

Haha, the original idea was to use it for light gaming with Steam.

I'll give those a try Crash2009!

I had similar issues with 3544.75, on protected content (seemed OK on unprotected content). PC froze solid starting a playback of a copy-once program. Reverted to 344.65. Nvidia's download site shows latest for GT430 and GTX750 is 344.75 at this moment.

Here is the 80, haven't seen 82 or 89 yet http://nvidia.custhelp.com/app/answers/detail/a_id/3607

I tried 344.80 and it didn't do any better. Froze solid like 344.75.

I can't for the life of me get the "Content type reported to the display" to stay with every turn of the projector.

Think the videocard is detecting it new every time and resetting to automatic. =\

[Crash2009]

Are you trying to display to 2 monitors at the same time. If so have you tried a hdmi switch?

[Kamzu]

Hrm... haven't tried an HDMI switch yet.

Put the HDMI switch in between the HTPC and the receiver?

And no, the computer is only connected to the receiver to output to the projector.

Your issue sounds like a similar one of mine - HDMI switch will probably not help with this. You need to stabilize Windows detection of the EDID data. Probably your best bet is something like the Geffen HDMI Detective (isn't cheap, about $100, but consider it might pay back in grief savings).

Connect this between your PC and AVR. Plug in AC adapter and program per instructions. Make sure to leave the HDCP switch on always. After programming you can disconnect the AC adapter.

This will make sure the PC always sees consistent EDID data from your signal chain. My experience is sometimes the timing (or whatever) of EDID responses from the downstream equipment creates Windows hotplug events on the display, and the drivers interpret this as a display change - and reset the parameters to defaults.

I've had one of these in my signal chain for a few years, and no longer experience these reset issues.

Does everything work as expected if you bypass the receiver? HTPC direct to projector.

FWIW, I've always connected my Nvidia cards directly to my TVs for video and used motherboard S/PDIF to the AVR for audio, and have had zero problems. I recently decided to once again try going through my AVR for both, and I ended up buying an HDMI Detective for the first time. While it solved the disappearing secondary display problem (the TV is the secondary), starting WMC would always cause the TV to blank and the HDMI light to briefly go out on the AVR. This did not happen with XBMC. My guess was WMC was renegotiating HDCP every time it was started. This never happened when I connected directly to the TV. The final straw was when I found some of my protected channels and recordings would freeze or give an error message after a second or two using the latest Nvidia drivers. Again, this did not happen when I reconnected directly to the TV. Reading the Geffen forums, for a time they were saying that Nvidia has buggy HDCP and recommended AMD. Maybe it still does, maybe there's been a regression, maybe it's my equipment (GT640, Panasonic 50ST60, Pioneer VSX-1124), but I have no problems with a BD player or Apple TV.

Anyway, I returned the HDMI Detective and have given up on this idea permanently for my HTPC. OTOH, the gaming machine is fine through the AVR (need it that way for LPCM 5.1 from games), and I use an EDID override to keep Windows from losing the TV configuration. Sure, the TV and sound come and go as Windows devices as I switch inputs on the AVR, but they come back with the correct configuration every time, no Detective required. The TV is also the secondary display on that machine. The cool thing is that for my handful of rips that use the lossless multichannel audio formats, I can watch them on my gaming machine using XBMC. I never really needed to try to make my HTPC work through the AVR for that.

There's always more than one way to "skin a cat". I didn't realize the problem stems from WMC. I wanted more flexibility in my setup, EDID reliability, and HDMI purity, so I went down the HDMI 4x4 switcher avenue. I have the HTPC, 2 extenders, and a laptop connected as sources. 2 TV's, a projector, and a Sony sound bar are connected as displays. Everything is connected using HDMI, and this allows for any source to any or all displays. The switcher is on full time and prevents arguments between the sources and displays.

If I connect the projector directly to the computer, wouldn't that defeat the purpose of having the receiver direct video/audio traffic for the other devices?

I suggested that just as a test.

What receiver do you have?

Does the receiver support HDMI pass through?

[Kamzu]

Sorry I haven't responded in so long. I have a Yamaha CX-A5000. I think it does support HDMI pass-through.

[Crash2009]

Wow! Nice! You would think that one would do anything you want. http://usa.yamaha.com/products/audio-vi ... 0_black_u/

That amp is totally beyond my peg rate. However, if someone dropped in in my lap and said make it work, I would start by configuring the source (HTPC) and projector (destination) to work without the amp, then put the amp in the middle and figure out what must be done to match the source to the destination. Set the HTPC to 1080 X 1920. Set the projector to the same. Then configure the amp's HDMI in and out to the same 1080 X 1920.

http://www.avsforum.com/forum/90-receiv ... repro.html might be a better place to get answers on how to setup the amp.

Unless someone else has a better idea???????

[Kamzu]

Thanks so much for all these ideas! Right now I'm just manually converting the setting to "Full Screen" every time I turn it on.

I'll look into those websites you listed.

Luckily I haven't had this problem with an LG LCD in my bedroom.

manually converting "What Setting to Full Screen" every time you turn "What" on

[Kamzu]

What I meant is that every time I turn the projector on, I need to go into NVIDIA Control Panel -> Display -> Adjust desktop color settings -> and change the drop down menu to report that what's displayed is Full Screen Video.

Unless I do that, the screen will blank to black periodically when I watch TV in Windows Media Center while full screened.
