Hello forum.

I had an EVGA GTS 250, and I used to plug it's HDMI out into a WHDI sender, which transmitted into its receiver 15ft away, which then connected to a 42" Samsung TV through another HDMI cable. It was perfect, stable, no perceivable latency, and took no setting up. I just plugged everything the first time and that was it.
It sends 5.1 audio, and Windows/nVidia Control Center detected the TV by its name.
The WHDI device is this one: (mine is of a no name generic brand, but it's the same one, even the box)

Now I bought an EVGA GTX 650, and WHDI doesn't work anymore. Nothing else changed.
Windows/nVidia Control Center won't detect the TV, only the monitor that's connected via DVI. The TV screen shows "[whdi device name] connected. Check video signal." on top of a black screen.

The HDMI on this new card works on other monitors. If I put the older card back, WHDI works normally.

I have googled this a lot, and once bumped into a page that showed how to force a display device to always-on through regedit. Once I restarted windows, the Tv through WHDI displayed my expanded (or duplicated) desktop at 1024x768, and listed the display as "digital display". I could not change the resolution and it wouldn't playback audio (although the option was available at nVidia Control Center HDMI audio options, but did not work).

The last thing I tried was (after reverting the registry settings for forced display detection to none). Didn't work.

Do any of you have an idea of what may be going on? I can't stand the thought of having a us$200 device not working because of the addition of a newer graphics card, when the much older one had no issues.

thanks,
a gamer desperate to play Bioshock Infinite on the living room with a raging 5.1 sound system.

I don't have an answer for you and I'm trying to find someone who can.

 
thanks, man.

 
thanks for the answer. Unfortunately from the process of elimination it does appear that the problem lies not with any piece of equipment other than the 650. As I said, installing the EVGA GTS 250 back on makes everything work again.

I agree that the issue may be handshake-related, but who introduced it was the 650.
So, the WHDI does not provide support for the 650? We know this isn't the case since these devices are pretty universal, the only requirement being HDMI 1.1.  I can also use it with another desktop PC (Intel VGA), 2 different PC notebooks, a Macbook Pro, with the same TV, or with a 22" Samsung display. I have a lot of cables too and I have tried them all.

I've also tried every possible power-cycle and cable-reconnecting order (literally - I made a chart). 

Could there be some kind of a software fix? A way to force the HDMI signal or port to be on? A set of configuration files or something else that tells my computer that there is a display device there? 

My last resort would be selling this card (and in Brazil this means losing 50% of what I paid for it).
I would definitely not have the money for a new one, and would have to use my old one.

Thanks in advance!

 
 
 

My drivers are always up to date, and I'm sorry, but older drivers is not a solution, and even if it were, I could not know which version would happen to work without trying one by one. 

Any other ideas?

Thanks for the response again, Chris. 
The TV does work with the 650 directly through HDMI. 
But so does the GTS 250 through the WHDI.
Also, there is no firmware for this device, and nor there should be since its only requirement is an HDMI signal (1.1 and above), and EDID information bypasses the device.

Hi Matt, 
I already contacted the manufacturer of the WHDI device, who told me what I previously mentioned here: that there is no firmware update for this hardware because it does not and it will never need firmware updates - it's made to work with anything provided it's HDMI 1.1 and above. It should not need any changes because the GFX card manufacturer decided to include a weird chip that doesn't send the signal unless the receiving end is part of a specific list! This makes no sense. 
GFX card should detect the EDID, send the adequate video and audio signal, and that should be the end of it.

I've established that the WHDI does send EDID, since the 250 picks it up.
The 650 does not detect it, does not send video/audio, and that's the whole issue here!

Now, just to amaze you even more:

I've bought a DVI-D (Dual Link) to HDMI adaptor, and used it to plug the HDMI cable coming from the WHDI in the DVI-D port of the 650.
Guess what? It worked perfectly - for a moment. Even audio. Problem is that I had to unplug the computer's main display for it to work (which by the way, shouldn't need to happen); when I tried to plug it back in, it never worked anymore. I tried for hours, every possible combination of connections, in every possible order; every possible power cycle combinations too. I made a freaking chart to keep track.

Do you realize how frustrating this is? I bought this 650 ten months ago. I've been trying it on and off for that long.
Since the WHDI is impossible to sell (no on wants or knows what it is, for this matter), I'm either stuck with an unusable $300 equipment, or I sell the 650 for half what I paid, if I'm lucky.

That's just because there is NO support, NO documentation on this, nothing. If I at least had a clue of what the problem is, I could fix it myself.

So thanks for showing up, but no problem is solved by "you should talk to the other guy, this is not my problem". 

The WHDI does work. With another EVGA card, also.
It also works on my dvd players, mobile phone, a Vaio and a Macbook Pro.

The only math that doesn't add up is the EVGA GTX 650.

I understand the temptation to blame the other, but you can only convince yourselves.

hmm, i will try that, wmmills. I'll let you know the results.

Matt, 
we'll have to agree to disagree, since you're suggesting I expect you to support the WHDI.
I expect support to the EVGA card, which I will not get, apparently.

It is possible that one will work with this device while the other does not. Technology changes. 

What?? No. Not possible at all. These devices are made to work with each other every time, no questions asked, no tech support needed, no technology changes involved!
 
However, you said it yourself that the cards have different "hardware and chips": which means the culprit is, indeed, the differences between the cards.

When you go upgrade your VGA, do you ask around if it will detect your display device, when using the currently most popular and standardized video connection? Of course not! It should on all accounts, work with no issues, unless there's something wrong with the VGA.

You can't possibly agree that it's OK for a VGA card to drop compatibility with a newer technology in a 4 year gap.


When the 250 came out, WHDI didn't even exist yet, but it supports it.
650 comes out after WHDI is already an established product, and it doesn't work? 
This makes no sense whatsoever.

Please, if there's no solution to this, advise me on how to get a refund.

It does work just fine on DVI and HDMI, which are the two popular standardized video connections.

WHDI, on the other hand... I had to look it up to find out what you were talking about, and I'm not surprised that you're having problems with it.

What flavor of 650 did you buy?  650 Ti Boost, 650 Ti, 650 SC, etc?  Let's start there and work our way backwards.  There might be some things we can do.

It's understandable.  We all get upset whenever we spend a sizable amount of money on something that isn't working to our expectations.  The only thing I can think of is that for its time the 250 was considered a mid-to-high range card.  The 650 would be considered a lower end card by today's standards (lower memory bus, etc).  There are only a few things I can think of, which I will list for clarity:
 
1) Try a different PCIe slot for the card.
2) Does your version use the mini-HDMI port?  If so, you could have a bad adapter.  If you can get your hands on one, see if that is the issue.
3) You could try reflashing the bios of the card.  You would have to contact EVGA customer support.  There are sites that have them, which I can PM you with, that you can get them from.  However, I highly suggest just contacting customer support on the forums or here to see if they can send you a BIOS.
4) The last possibility is that the card may be defective.  I am not sure if you are outside the warranty or not.  WHDI is a fairly new in terms of the others (I think HDMI was early 2000, DVI is really effing old and WHDI was 2006 or 2007, iirc).  The device you have may be working off an old standard (even if it works with the 250).  Unless you bought it yesterday AND it was fairly recent (within a year), it is hard to tell.  
 
Lastly, I am not saying any of the hardware (the WHDI device, the 250 or the 650) is garbage or fubar'd unless I specifically stated it is possible (ala the 650 possibly being defective).  I am just saying that it is possible that the card sends a different type of EDID that the WHDI device may not understand.  *shrug.  I hope one of these suggestions helps.  If not, I have a fifth option:
 
5) Grab a six pack, find a secluded area with clearing enough for a gas fire.  Light the 650 on fire and repeatedly smash it with a baseball bat.

I am aware of what the generation and performance bracket numbers of each card signifies.  I have been using Nvidia GPUs since the 8800.  The 250 was a 256-bit memory bus graphics card, which puts it firmly in the mid to high range of its generation.  It was able to do things with games of its generation that put its performance much higher than its "performance bracket" numbers indicate.  The 650, on the other hand, cannot handle most games of its generation past high settings.  

While it looks good for marketing, the generation and subcategory numbers are just a reference.  When these cards were tested, the 250 performed comparably higher than the 650 for its generation.
