GTX 260 HDCP Issues

post #1 of 10
Thread Starter 
First post I've made. You guys have already taught me so much with the information I've browsed just trying to build up the guts to start oc'ing my computer. However, before I get to that point, I'd like to resolve this display issue:

I am having HDCP Compatibility issues between my EVGA GTX 260 and my HP 37'' LC3760N LCD TV. The TV is HDCP compliant, I have looked through the users manual to confirm that. However, I am unable to get my GTX 260 (270.61 drivers) to recognize the TV consistently. When it does recognize the TV, I only get a black screen, and the nvidia control panel says that the TV is not HDCP compliant (Which is untrue, according to everything I've read about the TV).

I don't know if this is a driver issue, and provided it is, do you have any recommendations as to which drivers I should be using to solve this HDCP issue?

I am not sure what kind of response this will get, seeing as I am a total Noob here, but any advice/ideas/assistance would be greatly appreciated. I have been suffering with this issue for a long time with no avail. Generally, I have just sucked it up and used an s-video connection just so I could use my TV with my rig. However, I am sick of s-video, and I know there has to be some kind of solution to this problem that doesn't involve me setting fire to either my TV or PC.

If you're using HDMI - HDMI or DVI - HDMI, it's likely driver related as those connections support HDCP.

Try 266.58 and 275.33

Regardless, you only need an HDCP enabled connection if you have a BluRay drive in your PC and you're trying to watch a movie from an actual BluRay disc on the HDTV as it needs a secure/proper connection to decrypt it on-the-fly. If it doesn't have a secure connection to decrypt the keys as you watch, it will display a blank screen as that's the purpose of the encryption. It was originally intended to prevent connection switching to bypass protection when BluRay was first released, but, it's irrelevant as the Crypto-Keys were cracked in a matter of days by a college student shortly after BluRay's release. Actually, it was more of a bypass, but, that's another story for another time.

Thank you so much for your response! I'm downloading both the drivers now and will post updates as soon as I've tried them out.

I've heard a small amount about the Crypto-keys being bypassed as sort of a running joke about content protection, but if I implemented it, would it actually bypass my videocard not recognizing my TV as HDCP compatible?

Switching to the 266.58 Driver did not solve the problem. I noticed that my TV does not show up as a display while it is on, but once it is off, it appears just fine, but still says it is not HDCP Capable. I am so baffled by this problem.

EDIT:
After wiping the 266.58 driver and switching to 275.33, I am still experiencing the same problem. I can get the HDTV to appear in the control panel as HP HDMI, but there is no picture and it still says the display is not HDCP compatible. I am beginning to think the GTX 260 might be faulty, but I have never had any other issues aside from this one.

Okay...this is weird...I switched the ports. Now it works. I swapped my DVI-VGA monitor port with the DVI-HDMI port....and it works. ???

Because HDMI to HDMI or DVI to HDMI is required for HDCP as it's a digital connection, DVI - VGA is an analog connection. I mentioned this in my first post.

Well, the problem has reappeared. Here is what I posted on the Nvidia support website:

When my HP LC3760N 37'' HDTV is connected to my GTX 260 via dvi-hdmi adapter, it does not appear in the Nvidia control center unless the television is turned off. While turned off, it appears as a secondary display with the name HP HDMI. When I turn it on, it disappears. This problem has been driving me nuts. The TV is HDCP compliant, the HDMI cable functions properly. My primary monitor works without any difficulty. I have tried the 275.33 drivers, the 270.61 drivers and the 266.58 drivers and none of them will recognize the HP LC3760N while the television is actually turned on. HELP ME PLEASE.


As of 10:09 PM EST I have replicated this issue with 4 other drivers:

196.21
260.99
267.24
275.27

I currently have the 275.33 drivers installed. I have managed to get the HP LC3760N HDTV to appear in the control center whether it is off or on with these drivers, and these drivers only. However, no picture has appeared. The HDTV remains blank. I've tried every scalable resolution the TV is capable of. I have tried both of the HDMI inputs on the TV. I have switched the cable with another cable. I have swapped the dvi ports the two monitors are plugged into, all to no avail. I am certain this is a driver bug that has gone unanswered for a looong time. Please do something. I really, really would like to be able to watch movies from my PC in 1080i without having to spend 5 hours wiping and re-installing every driver available. I am considering selling my GTX 260 and buying an ATI card, because this is total hogwash.

You have a 260, a standard/mainstream powerful card, and it's not from some odd off off brand that's screwy.


The only remaining variable is your TV itself, bring your system to a friends house and see if it works with their HDTV.

And/or, try another system with the same HDTV.

On a random note, I'm addicted to Demon's Souls for PS3.

Actually I went from ati to nvidia just because ati has problems with HDTVS (more than nvidia). With ati there are a lot of hdtvs that when you run dx10/dx11 due to the way its coded makes your signal 1080i only (and if you select 1080p theres no signal). It was a real pain in the ass.

Every card from every manufacturer has random issues, it's as simple as that.

No company is superior to another one, it may seem that way, but, people have wants/needs that are relative only to them so card A will seem more worth it than card B.
