GTX 760 problems with integrated HD 4000 graphics and with connecting VGA projector

Hi there!

Yesterday I bought GTX 760 4GB (GTX760 EX OC PCI-E 4GB DDR5 256BIT) from a less-known company KFA2. However, I am experiencing some problems:

1. I cannot enable my Intel HD 4000 graphics, because my monitor turns off after a restart and there is no picture whether I connect it to KFA2 GTX 760 DVI socket or the integrated graphics DVI socket. I need to be able to use integrated graphics along with GTX 760. I didn't have any problems like that with my previous card: Asus GTX 560.

2. I cannot set my projector to be the second display. My VGA projector can only be connected through VGA-DVI adapter that they supplied me with and it only goes into the first DVI socket, which is marked as DVI-I. I cannot insert it into the second DVI socket (DVI-D) because it's incompatible. Thus, every time I boot my computer I have to have my projector turned on to see the bios start-up message and to choose which system I want to boot. This is unacceptable for me.

My rig: Intel i7 3770k, OCZ modxtreme 500W 80+, 16GB 1600Mhz RAM Corsair, Windows 7 64bit

I have eight days left to deal with these problems and if they cannot be solved during that time I will return the product to the shop and I will choose an Asus card.

I really hope you can help me with it, cause KFA2 is the only card having 4GB VRam in this price in Poland and PLEASE, DO NOT START THE DISCUSSION WHY I CHOSE 4GB OVER 2GB. It's irrelevant. :)

is your integrated graphics enabled?

-You can use integrated graphics 4000 and GTX 760 separately if that's what you are trying to do.

Thanx for reply, but you didn't get what I was saying. My HD 4000 is DISABLED because when I enable it there is no video signal at all. It's like that: I boot, start Windows and when system drivers load up the monitor goes blank. It doesn't matter which DVI socket I plug my connector in. With HD 4000 enabled there is no video signal in ANY DVI sockets, nor HDMI. I know I CAN use HD 4000 and GTX at the same time, because, as I have already written, I had no problems using my old GTX 560 and HD 4000 simultaneously. I am not the only one experiencing this problem. I have read it happens to some people with different cards as well.

so does the integrated graphics work when the GTX 760 is not connected to the motherboard?

To give you more info. Here's the answer from KFA2 Support:

Quote:
From what you have described below it would seem there is no fault with the card, but with your current setup.

Using your integrated graphics as well as a standalone graphics card is almost unheard of these days, as our customers would have both monitors hooked up to their graphics card.

Could you please explain why you need integrated graphics alongside a standalone graphics card?

If you are using two displays that are currently VGA connections, then you cannot connect both to your graphics card.

The reason for this is that our cards do not have two slots for analog signals. They only have one DVI-I connector that will take a converted analog signal.


As you can see from the picture below the DVI-I will accept a Digital & Analog signal, whereas a DVI-D will only accept a digital signal;

The HDMI & DP (DisplayPort) are also digital inputs are will only accept a digital signal. Therefore connecting an analog input into a digital only input will not give you an output.

My suggestion would be to setup your monitors in the same fashion as below;

By connecting your graphic card’s DVI-D port, via a DVI cable, directly into your TFT’s DVI-I/D port will allow a digital output to be connected to a digital input.

By connecting your graphic card’s DVI-I port directly to a DVI to VGA adaptor/connector, you are converting a analog DVI signal into an analog VGA signal.

You can then connect your projector directly to the DVI to VGA adaptor/connector via a VGA Cable.

I hope the above has been made clear to you, should you require any further information please do not hesitate to contact me.


And here is what I replied:

Thank you for your swift response.

Let me start with the first topic.

I have already connected my projector and monitor just like you show in the pictures. There is no other way to connect them anyway. The problem is, as I have stated before, that the PROJECTOR IS RECOGNISED AS A PRIMARY DISPLAY and my LCD MONITOR IS RECOGNISED AS THE SECONDARY DISPLAY. Thus, every time I boot my computer I have to have my projector turned on to see the bios start-up message and to choose which system I want to boot. This is unacceptable for me.

The second thing - about HD 4000: I need it to have Lucid Logix Virtu MVP enabled. There are a few games that work miraculously well with it. Plus, the second thing is that if it worked, I would be able to connect my projector to it and the first problem would be solved.
