Video Card with both DVI-D and Display Port Connectivity.

Can anyone here suggest/recommend a decent PCI-E video card that has DVI-D and Display Port connectivity?

I notice that quite a few of the lower-end cards are now offering Display Port these days...which supposedly offers optimal digital signal/image quality.

Please note - I'm not a gamer, I just want it for my photo editing (CS5 and NX2) with my new NEC P241w monitor.

With so many cards out there on the market these days...it's hard to narrow it down.

Budget up to *$150* max.

Cheers,

KEV

You'll want a Pro series card for 10 bit per channel support

If you're trying to get 30 bit (10 bit per channel) color support, you'll need to move up to a card that has drivers to support a 10 bit per color pipeline. None of the non Pro cards work that way, even if they have a DisplayPort.

For example, none of the Radeon HD series cards with DisplayPorts will allow a 10 bit per color pipeline with CS5, even if you use a DisplayPort.

To get 10 bit per channel color, you'll need to move up to one of the Pro Series cards like an ATI/AMD Firepro card. Those have drivers that support 30 bit (10 bit per channel) color with some apps like CS5. The drivers for the non pro cards (e.g. Radeon series) do not support 10 bit per channel color.

Here's a .pdf file on the subject from Eizo:

http://www.eizo.com/global/support/compatibility/monitors/20.pdf

Here's one from AMD:

http://www.amd.com/us/Documents/48108-B_ATI_FirePro_Adobe_10-Bit_FAQ_R5_Final.pdf

Note that some newer Firepro cards have been released since those docs were published. For example, the Firepro V3900 and V4900 were launched in February and should also work.

http://www.anandtech.com/show/5512/amd-announces-turks-based-firepro-v3900

If you can stretch your $150 budget by $10 or so, I'd probably look at the Firepro V4800 (or newer V4900). The V4900 sells for around $159 at vendors like newegg.com.

If not, then you may want to stick with a Firepro V3800 (or newer V3900).

Please note - I'm not a gamer, I just want it for my photo editing (CS5 and NX2) with my new NEC P241w monitor.

Note that very few apps will support 10 bit per channel color. CS5 will using some of the ATI Firepro cards. But, note that you may need to disable Windows Aero features while working in CS5, because the Windows Aero Desktop does not support 30 bit (10 bit per channel) color.

one of these two...

I see you're in Canada. I don't know much about vendors there, but newegg has a .ca we site.

If that $150 budget is firm, I'd probably look at the Firepro V3900 (newer card that was just released in February) instead of the V3800. This card:

http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3900/Pages/v3900.aspx

newegg canada has it here:

http://www.newegg.ca/Store/BrandSubCategory.aspx?Brand=1126&SubCategory=449&name=ATI-Professional-Graphics-Cards

If you can stretch your budget a bit and want a faster card, I'd look at the new Firepro V4900 (also released in February) instead of the V4800. This card:

http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v4900/Pages/v4900.aspx

newegg canada has it here:

http://www.newegg.ca/Product/Product.aspx?Item=N82E16814195109&Tpk=v4900

Those both support a 10 bit per channel (30 bit) color pipeline, as does your NEC PA241W with an application that supports 30 bit color (and very few programs will). Refer to this AMD ,pdf on how to get that working with CS5:

http://www.amd.com/us/Documents/48108-B_ATI_FirePro_Adobe_10-Bit_FAQ_R5_Final.pdf

P241w versus PA241W - 8 bit versus 10 bit panel

I just realized you said P241W versus PA241W.

According to TFT Central, the P241W only has 24 bit (8 bits per channel) color depth:

http://www.tftcentral.co.uk/reviews/nec_p241w.htm

That's probably why it's not listed as a supported display in the AMD docs on how to setup CS5 for 10 bit per channel color with one of the Firepro cards supporting that feature.

http://www.amd.com/us/Documents/48108-B_ATI_FirePro_Adobe_10-Bit_FAQ_R5_Final.pdf

I also see that NEC's web site also shows only 16.7 Million displayable colors (8 bit per channel color).

http://www.necdisplay.com/p/desktop%20-monitors/p241w-bk

It does have a lookup table inside that's supposed to help. But, it looks like it's still mapping the input back to 24 bit (8 bits per channel) color, since the panel does not appear to be 30 bit capable.

I'm no expert on the subject.. But, on the surface, I'm guessing that you may not gain anything by going to a Firepro card supporting a 30 bit color pipeline since the panel itself is 24 bit (8 bits per channel) supporting 16.7 Million colors (even though the lookup table can handle more before it gets to the actual panel).

Re: P241w versus PA241W - 8 bit versus 10 bit panel

Thanks Jim for your imput here.

I'll digest what you've said and take a look at those links.
Yes, the NEC P241w is 8-bit.
So I guess a regular...but semi-decent $150 range vid card will be OK/fine.

Is there any noticable difference in image quality between using the newer display port connection....and the regular DVI-D?

Just curious...

Cheers,

KEV

Not that I'm aware of. They're both digital, so you should see no difference between them unless you need to take advantage of 10 bit per channel color via a displayport.

What video card (or integrated chipset) do you have now?

What kind of PSU (Power Supply) do you have?

In order to support anything more than a bus powered card, you need a heftier power supply than is normally found in most name brand PCs, as most "off the shelf" PCs only have a 300 or 350 Watt PSU in them; and the mid to higher range video cards are going to need more power with dedicated power connections from the PSU.

So, unless you have a better PSU than you'll find in most off the shelf computers, you'll probably be limited to entry level cards (GT 440 or lower in the Nvidia lineup; HD 6570 or lower in the AMD lineup) that don't require a better PSU with dedicated power connections to the video card.

IOW, let us know what kind of PC and PSU (brand/model) you've got for starters for better responses.

I'm still running my old (2006) dual-core, with the Asus P5BVM (S775) Motherboard and integrated chipset. Altho, I did upgrade the power supply to 500W when I bought the system coz it went belly-up.

So, at present I only have the analog VGA connectivity which obviously isn't using the NEC P241w image potential.

I'm going to get a new tower built this summer...so I just want a reasonable temporary video card I can slot into the MB to get a better image quality and utilize the NEC monitor's digital capability, etc.

For now...

With that in mind...any suggestions would be a real help.

I guess I don't really NEED diplay port...if there's no image upgrade over DVI-D.

Personally, I'd probably go with an Nvidia GTX 550Ti if I had a $150 budget with a 500 Watt PSU. I'm currently using a bus powered Nvidia GT 440 with 1GB of GDDR5 (not slower GDDR3) now and the extra speed of the much faster GTX 550Ti would come in handy for some purposes.

But, I'm partial to Nvidia chipsets, since Nvidia's proprietary CUDA technology is supported by a number of apps, and tends to have better LInux support, too (and I use Linux most of the time, with PCs setup in multi-boot configs with 64 Bit Win 7 and LInux distros on them).

Here are some GTX 550Ti cards at newegg canada, sorted by lowest price first.

http://www.newegg.ca/Product/ProductList.aspx?Submit=ENE&N=100007708%20600094002%20600122953&IsNodeId=1&name=GeForce%20GTX%20550%20Ti%20%28Fermi%29&Order=PRICE&Pagesize=20

Note that the two Zotac brand cards they stock have DisplayPorts. But note that the current Nvidia Windows drivers for it don't support 10 bit per channel color (although the latest Linux drivers from Nvidia do).

NEC - P241w Specs

Jim,

According to the NEC P241w specs....using the display port connection this model offers 10-bit with 1 Billion colours (so long as the video card does also of course).....whereas, the regular DVI-D connection offers the normal 16.7 million colours. Wouldn't this imply that using the display port...would indeed create a better image and be the prefered way to go?

Re: NEC - P241w Specs

Been out all day today - interesting points. Must be a standard Single Link DVI-D port and not a Dual Link DVI-D. I believe Dual Link DVI-D can support up to 48 bits per pixel.

Regardless, I'm not sure you'd see the difference except that banding should be minimal via DisplayPort as versus the DVI port. Even via DisplayPort, this monitor, like most that currently claim to be 10bit panels, will only display 16.7 million of the 1.07 billion available.

Why is that?
What's the point of them making such false claims?

Re: NEC - P241w Specs

I don't see where you're seeing that in the specs.

I do see where it claims 1.05 Billion Colors in the LUT (lookup table) But, the specifications still shows it's only capable of displaying 16.7 Million Colors out of the available 1.05 Billion. Scroll down to the "Display Colors" section on this page:

http://www.necdisplay.com/p/desktop%20-monitors/p241w-bk

16.7 Million Colors is 8 bit. So, I don't understand the point of having higher bit inputs and lookup tables, if it's just being converted back to 8 bit when it gets to the panel (as from everything I've found, the panel itself is only 8 bit, even though the electronics prior to the panel may support higher bit depths).

Most of the monitors with the so called 10bit panels have literature somewhere that clarifies that while the monitor's electronics will process a color depth of 1.07 billion colors (10bit) what is displayed is 16.7 million colors (8bit).

In theory this should mean less banding artifacts in images such as sunsets etc where their is a panoramic gradient.

With the P241w it is mentioned on the product web page and in their brochure.

re: one of these two...

Again, I do not understand the benefit of having a higher bit rate via a DisplayPort and internal LUT, if it's just being mapped back to 8 bits at the panel.

But, if you want to see if 10 bits is any better, again, go with one of the two cards I mentioned earlier in this thread if you're trying to stay within a $150 budget:

http://forums.dpreview.com/forums/read.asp?forum=1004&message=41114309

The consumer level cards do not support a 10 bit per channel pipeline (the drivers don't support it, even if the hardware will, so you'll need one of the Professional series cards like the Firepro cards mentioned).

Again, also note that you'll only see any benefit using CS5 with a full 10 bit per channel pipeline and display, as very few apps can use 10 bits per channel; and I'm not sure you'll see any benefit at all with an 8 bit panel, even though the internal LUT and electronics support higher bit rates.

I decided to get the new AMD Firepro V3900 card...coz with taxes it comes in right on my budget at $151 here in Canada.

I just looked at page 26 of my user manual and it says.

Display Colours 1,073,741,824 (DisplayPort 10 bit)
16,777,216 (DVI)

So reading that....one would naturally assume that the display port used 1.07 billion colours.....and the DVI just 16.7 million.

IF that's not the case...they should word/present it differently.

Great.
The clarity upgrade is significant.
Especially text, which is sharp, well defined and very clean.
Installing the card and drivers was problem free.

Combined with my new NEC P241w monitor...it's as good as I need.
