Hello, I need advice on what graphics card to buy for two machines.
I can't see any rhyme or reason in the obscure world of graphics card marketing, so best I ask my question direct. These are business computers so none of the gaming stuff applies.

Machine 1: "ACCOUNTS-PC" - A regular desktop PC for our accounts girl. We want to run 3 monitors on this machine. All the latest PC's can do this with onboard graphics (Intel 530 or 630) but this PC is about 2 years old and can't do 3 with onboard graphics. So, I called an IT store and asked them to recommend a card. They suggested the ASUS GeForce GT 730 2GB GDDR3 Graphics Card. I bought it, installed it and it didn't work. In the driver interface when I try to select the 3rd monitor it gives an error "This card supports up to 2 monitors". So I'm back to the drawing board. There is absolutely no gaming or even video watching on this computer - it's Reckon Accounts and MS Excel use mainly. What card should I get for this?
This computer has an 2015 i5 CPU and 8GB RAM.

Machine 2: "TECH-PC" - this is my computer, a fairly high powered desktop PC with i7-6700 CPU, 16GB RAM and a 500GB SSD drive. This chip is new enough to run 3 monitors from onboard graphics, however one monitor is a 30 inch 2560x1600 monitor. (the other two are only 1680x1050 and 1366x768, at least for now). When I first got this monitor a year ago, I was able to make it run by winding the refresh rate on the 30" down to 30fps. However after the latest Windows update I can no longer do this.
This computer is used for occasional video editing with Premiere and some Autodesk work so a card is probably justified. But what card should I buy that will definitely be able to run 3 monitors, one being 2560x1600?
For this computer I would give preference to a card that can support 4 monitors to give me another option for a side or wall display in the future.

One final note...I am NOT INTERESTED in garbage cards that use DisplayPort or any other boutique interface. How many monitors are there under $250 that have DisplayPort inputs??? None. The industry standard monitor interfaces are VGA, DVI and HDMI.

MANY THANKS in advance for those that can help me!!
 
I don't know how to break this to you, so I'm gonna give it to you straight. VGA and DVI are for people who are desperate to hang on to old monitors. HDMI is for people who might need the convenience of an HDtv hookup.

Display port is ideal. For one thing, it's how a 4 monitor setup is possible. Technically, when you use VGA, DVI, and HDMI you are limited to 3 monitors max. That's because they all share certain dependencies. Display port frees you from that.

All this tech is designed to work a certain way. What you should do is decide what your needs are, then choose components that are designed for that purpose. The hard way, as you've discovered, is to say "These are the components I have, how can I force them to work the way I want?".

It would be helpful if you listed the monitors for each setup, or at least which inputs you plan to use for each setup.
 
I knew someone would stand up and spout about displayport making America great again. just for the record, my Kogan 30" monitor does appear to have a displayport input - so ONE monitor out of six.
Also for the record I had an older ATI Radeon card that ran 4 displays without needing any DisplayPort rubbish - but it was probably 5 years old and died. That was on Windows 7. Hopefully another 5 years and the gimmicky DP will be a memory, like Firewire, external e-SATA plugs, and the days when every Motorola and Nokia flip phone had a slightly different charging port.

Can anyone suggest a graphics card that fits my needs?
I don't care paying $200 per card if it's definitely going to do the job.
