Good graphics card supports monitor I have chosen

That's a great card for the money. But I noticed you were asking about 4K earlier in another post:

Modified: I guess i'll be hooking up via the graphics card doh! So the 750Ti says "Maximum digital Resolution 4096x2160". So am OK right?

A lot of GTX 750 Ti cards have a DisplayPort available (most cards from EVGA, and some cards from Asus and other manufacturers).

But, it looks like the card you're going with does not have one.

When you see specs on resolution, they can be misleading, because they always don't give you the refresh rate supported at a given resolution for a given port type.

For example, you can't get 4K at 60hz via an HDMI 1.4 port. You'll be limited to 3840x2160 at 30Hz, or 4096x2160 at 24Hz. You can't get 4K at 60Hz via a DVI port either (you're going to be limited to a max of 2560x1600 at 60Hz over dual link DVI).

Some cards and monitors have dual HDMI ports for what is known as HDMI MST (Multi Stream Transport), which sends dual 1920x1080 60Hz signals to a display, with the display combing them into a 3840x2160 output, which is another way to get that resolution at 60Hz via HDMI 1.4

So, a DisplayPort is desirable if you plan on moving to a 4K display at some point. I see that BenQ has a new 4K model coming out soon now. This one:

http://www.amazon.com/BenQ-BL2711U-27-Inch-Monitor-LED-Lit/dp/B00RORBPEW/

Note it's specs page here:

http://www.benq.us/product/monitor/bl2711u/specifications/

As you can see by it's specs, in order to get 3840x2160 at 60Hz, you need to use a DisplayPort or HDMI 2.0 port with it.

With other port types (DVI, HDMI 1.4), you're limited to a 30Hz refresh rate at a resolution that high.

That display is interesting in that it has both HDMI 1.4 and HDMI 2.0 ports. That's very rare (HDMI 2.0 port on a computer display vs TV). We're also starting to see some brand new 4K TVs with them now (HDMI 2.0 ports), and some do not have a DisplayPort. So, having HDMI 2.0 available gives you more options later for 4K.

HDMI 2.0 will support 4K at 60Hz. But, very few video cards have an HDMI 2.0 port yet. In the Nvidia lineup, if you moved up to the GTX 960, you'd get an HDMI 2.0 port capable of supporting 4K at 60Hz with TVs and Monitors with an HDMI 2.0 port (rare right now, so a DisplayPort is normally used for 4K at 60Hz with computer displays).

But, the GTX 750Ti HDMI port is a version 1.4 port (meaning you can't get 4K at 60Hz with it and would be limited to a lower refresh rate at higher resolutions). You'd want a GTX 750Ti card with a DisplayPort for 4K at 60Hz.

Anyway, with the monitor you're looking at, you should be fine with a dual link DVI connection from the GTX 750Ti for getting 2560x1440 at 60Hz.

But, if you think you may want to go 4K later, you may want to move up to a GTX 960 so you'll get a DisplayPort and an HDMI 2.0 port supporting 4K at 60Hz (or at least select a brand/model of the GTX 750 Ti that includes a DisplayPort, like some models from EVGA, Asus and others do now).

Of course, by the time you're ready to upgrade your monitor, the cost of a faster video card supporting the latest standards will probably be lower. So, you may not want to worry about it since you should be fine with the new monitor it looks like you're going with (2560x1440 at 60Hz is supported via a dual link DVI connection from that GTX 750 Ti you're looking at).

I looked at the configuration pages for the vendor it looks like you're going with (I'm assuming it's PCSpecialist.com since I see the same parts and warranty you selected available there via their configurators). Unfortunately, it only looks like they offer one model of the GTX 750 Ti (and do not specify the manufacturer and specific model number being used), and it does not have a DisplayPort like you'll find on 750 Ti cards from some of the cards from other brands.

So, with that vendor, it looks like your only option would be to move up to the GTX 960 to get a card with better output ports for supporting 4K at 60Hz. For 4K video editing, a GTX 960 is a better idea anyway, especially since it has both h.265 encoding and decoding available. For gaming at 4K, you'd also want a GTX 960 (or an even faster card for more demanding games).

But, again, with the monitor you're looking at now, the selected GTX 750 Ti card should work fine using a dual link DVI connection to it to get 2560x1440 at 60Hz.

I just posted this info since you were mentioning 4K compatibility in another post earlier when discussing the GTX 750 Ti specs, in order to let you know about the limitations of the card it looks like you're going with.

Hi Jim,

I've no plans to go to 4K at the moment but appreciate taking the time to outline this, which I can refer back to in the future.

Thanks

Carl

Re: If your card doesn't support DisplayPort

If your card doesn't support DisplayPort, then be sure to use DVI or VGA. I would avoid HDMI as much as possible.

If I'm not mistaken, the resolution of the monitor (2560x1440) is the maximum for VGA, so you shouldn't run into any issues. The monitor is very flexible and supports DP, HDMI, DVI, and VGA. You will be good to go with one of the wires Benq supplies for sure.

Re: If your card doesn't support DisplayPort

Hi guys,

As promised here is an update of how i'm getting on with my new PC. I've had it just a week and it's AWESOME! LR and PS are significantly faster and smoother; images are clearer and crisper on the new BenQ monitor (used a DVI cable to connect).

I'm still getting used to Windows 8.1 - not intuative is it...

All in all i'm well pleased. Thanks again for all your help.

Regards

Carl

Re: Help needed for Photoshop Lightroom PC

I'd also get an external backup drive with enough capacity to store all that data. (Plus personally I'd say 32GB too, as I ran out of my 16GB three times in the last week.)

Re: Awesome!

Glad to hear all this! I love that monitor. It makes everything so much more vibrant. Movies play very well also in case you ever want to watch one at your PC.

Windows 8.1 is a little funny, but it's sort of the same thing as any other Windows with a different layout. I wouldn't get too bothered by it. You should qualify to upgrade to Windows 10 in about a month.

Carl:

Very nice build. You will have a great system that will be stable and rewarding. Just think how much you learned to build your own box!

And a 27 inch 2560 x 1440 monitor is icing on the cake.

Enjoy!

Best Regards,

Guido

I already have one, so am OK there. Thanks for the comment though. I've tried to fill 16GB but can't. At the moment

Re: Help needed for Photoshop Lightroom PC

With hindsight I withdraw the 32GB comment as I think I do a bunch of atypical stuff. Although I was pretty amazed to see a chkdsk using over 10GB of RAM the other week.
