Hi guys,
I have an old but legendary 1080ti,but i added a few more monitors and bought a 730 with multiple HDMI ports for the extra ports.The 730 GPU doesnt work with the 1080ti drivers,i can get it to work only if i install older drivers,but then i am left with a 1080 with 4 year old drivers.
I am trying to install different drivers using device manager,i choose the 730 an specify which folder to look,but it keeps installing version 456.71 of drivers for both video cards.I cant get windows to install a set of drivers for the 1080ti and another for the 730.
Am i missing something? Or there is nothing i can do,and will just have to use the older drivers to get the 730 to work.
Thank you.
 
how many monitors are you running, 1080Ti should support 4, 3 DP and 1 HDMI. If you have only HDMI monitors, you can get DP to HDMI adaptors. probably $10 each.
 
I went down this same road with my 6 monitors.

The bottom line is, you CANNOT have multiple Nvidia drivers installed on the same system at the same time, period. This even applies if your secondary card is a Quadro (it will work but only if both cards are generationally compatible with the same driver)

The problem in your case is that the 730 is Kepler based. Kepler cards were dropped from the main driver a while back.

You have two/three options:
-You can get an AMD card as your 2nd card. This will work fine since there are no issues having Nvidia and AMD drivers installed simultaneously.
-You can get a 2nd Nvidia card that is newer than your 730, one that is still supported by the current driver.
-If your CPU has graphics built-in, you can use that for your extra monitors.

In my case I tried both options (my CPU doesn't have built-in graphics). I first ran with an AMD FirePro W2100 as my secondary card. This ran fine for the most part, but ultimately it was annoying having things controlled by two different drivers. Also when minor issues cropped up like G-Sync not working correctly, etc, it always made me wonder if that was the cause. I still use this in my backup computer though.
I ended up getting a GTX 750 Ti, which is pretty much the oldest and smallest card that is still supported by the current Nvidia driver. It works great with no quirks.

This is correct. I'd advise a newer card if possible for the OP, as Maxwell (750ti) is going to lose driver support probably this year or early next. A pascal card such as the 1030 would buy a couple of more years.

A pascal card will last forever. There's not going to be any new graphics after China occupies Taiwan and North Korea nukes South Korea, and after that Windows 12 will be too late for WW3 and the world as we know it.
So yeah Pascal if fair enough for the future, works on W11.
 
Thanks for the sugestions.My problem is i bought the cheapest 27 Dell monitors,and they only work well with HDMI,i basically need 3xHDMI outputs,and this 730 had 4 of them...its to late to return the monitors now,and im stuck finding a graphics card with enouth HDMI slots.

That's why you need to do some research when buying things for an uncommon setup (which 3+ monitors on multiple GPUs definitely is), because sometimes there is genuinely no recourse other than returning/exchanging what you already bought for something newer, or spending more money on things like adapters.

Your best bet for minimal hassle would probably be to get a GTX1050 or 1050Ti; some models have 1xHDMI + 2xDVI, and you can directly convert the DVI to HDMI with a straight HDMI->DVI cable, or get some cheap male DVI to female HDMI adapters so that you can use any HDMI cables you already have laying around.

Note that this only works for single link dvi bandwidth, so if his monitors are higher than 1080p, he won't be able to get a proper signal. Since he said his monitors are 27", it's likely that they're 2560x1440.
 
true but, there are still lots of 1080 monitors at 27"

op has two options: try the modded drivers, buy a different card.

Or use DP to HDMI adapters , or USB to HDMI adapters
I used a pair of the USB to HDMI adapters on this laptop for a client and they worked pretty decent, testing them in my room playing 3 different YouTube videos.

adapters arent magically going to fix the driver issues. those usb-c ones arent really adapters, they have built in video chips. he'll also have to buy several of them and have several usb 3+ for them to work.

I ordered these,according to the manufucturer website they support 4k 30,that should also mean 1440x60. They are dual link DVI adapters. https://conectica.ro/adaptoare-conv...d-dual-link-241-pini-la-hdmi-t-m-delock-65466
They will come tomorow and i will see if this works.

DP to HDMI adapters will allow the 1080Ti to drive all 4 monitors so no need for another card.
The USB to HDMI was only listed as another option, some people don't know they exist.
I personally would use adapters and the single 1080Ti.

No, but he bought the 730 because he ran out of HDMI ports on his 1080. Which still has 2 DP ports, so a DP to HDMI active adapter will let him drive 4 monitors from the main card, and the driver issue disappears because he doesn't need the 730 (if he's OK with "just" 4 monitors.)
