Question about different DVI port colors

I was just showing as example... There is OP's card's pictures in the quote above, anyway here is OP's card from XFX website;

Then it's not the same card?

Avengerpilot said:
So my XFX DD R9 280 has 2 DVI ports, the top one has a blue color and the bottom one has a red color.

Aquinus said:
The OP has a XFX card, that's an ASUS card... For the OP, one port is dual link, the other is single link in addition to one being DVI-I and the other being DVI-D respectively.

problem is they are both the same ports except a differnt color

This is EXACTLY my card all in HD http://www.newegg.com/Product/Product.aspx?Item=N82E16814150706 zoom in as you p[lease

As i mentioned both ports are DVI-I ports, the thing is normally you should be able to use passive port convertors like (dvi-i to vga) but VGA icon is only exists in blue port so you MAY NOT be able to use vga convertors in the red one. This should be the difference.

The card he has doesn't seem to quite match the spec page I linked earlier. Indeed, both parts look to be the same. XFX should have done something to differentiate them.

Apparently that's what the colors are for, but without a legend, knowing which is which is difficult.

@RevoLand, your pronouncement of them both as DVI-I is contrary to DVI's own specs, which I helpfully linked in post #2. However, you are right about them looking like exact copies! :-)

Well they are both 24+5 pin DVI so they are dual link dvi-i and as much as i know there is no difference between port sockets. (https://upload.wikimedia.org/wikipe...r_Types.svg/277px-DVI_Connector_Types.svg.png)

The only difference between DVI-I ports he has is one supports analog (blue port with vga icon) while other doesn't.

ah so since my montior is old peice of junk it is probably analog and since I hoo]ked it up in the non analog port it probably crapped out alot more

BLACK: dual-link (max digital resolution: 2560x1440) DVI-I (supports digital and analog). Analog max resolution is 1920x1200.
RED: single-link (max digital resolution: 1920x1200) DVI-D (supports digital only)
All resolutions are given assuming 60 Hz.

There are two reasons why they are colored differently:

They are both physically DVI-I connectors when one of the connectors is only DVI-D electrically.
One of the connectors is single-link while the other is dual-link which means different maximum resolutions (explained above).

I think we need a little bit of clarity with this diagram. This isn't to say that the DVI connector for any of these types will actually have a pin-out that looks like this (except for the cable itself,) but rather which pins are used to drive that type of DVI connection. For example, on the OP's card, both DVI ports have all of the same pins that DVI-I (dual link,) has but, one of them actually doesn't use 10 of those pins, even if they're on the port itself. I feel that clarification was needed as people are seeming to think just because the DVI port looks like it's DVI-I dual-link that they both are actually that, which isn't true. For example, the 4 pins around the flat pin are strictly used for analog but, they still exist on the connector for the DVI-D port.

so yeah it is 60 HZ, my current monitor can switch between 60 and 75, but if my next monitor is 144Hz will that matter? (and thank you I know it crashed because I was using digital this whole time and my monitor is analog)

FordGT90Concept · Jan 1, 2016

What make & model of monitor do you have?

Edit: Actually it doesn't really matter. If you're using DVI (digital or analog), use black. If you're going to get a new monitor with 144 Hz support, make sure it has DisplayPort connector and buy a DisplayPort to mini-DisplayPort cable.

If you're really concerned about refresh rates, it's all about bandwidth. The basic principle is this:

Code:

pixels wide * pixels high * bits per pixel * refresh rate = bits per second

Code:

1920 * 1200 * 24 * 60 = 3,317,760,000 or 3.32 Gbit/s

Note how that is under the DVI single-link maximum.

The crashes you are experiencing likely has nothing to do with this. The only reason a game could crash is if it is trying to force a resolution/refresh rate that is unsupported (PAYDAY 2 likes to do that, for example).[/code]

75hz should be fine on single link, depending on the resolution.

Also, you are not crashing because your monitor is analog. If it was, you would either be using a DVI-VGA adapter, or it would be impossible to plug in.

FordGT90Concept · Jan 1, 2016

Oh, I should correct my previous statement: if a DVI cable is loose or the DVI connector is loose, it can cause all kinds of problems. Make sure to screw them in!

hat · Jan 1, 2016

Weird video problems/black screens I could accept, but his entire PC crashing is way out there in left field. I can't think of any reason for that, just because he's using a different DVI port...

Yeah it stopped crashing whenever I put it in the blue port, and I switced from a 600 watt to a 1300 watt PSU and everything was underpowered but it crashed on games on the red port and stopped when I put it in the blue/;black port...that being said it may also be a combo of my fan control being brokem currently and Im waiting on my replacement cooler

Ok, I'm very confused what order things happened based on this paragraph.

Can you start at the beginning and sort it out step by step what happened?

I just have this funny feeling that crucial info we needed is hidden in here somewhere.

Display driver crashing, display corruption on a monitor, monitor disconnects/goes off unexpectedly, and can cause applications to crash that aren't coded to handle the aforementioned events (like Terraria).

I suppose the red port could cause problems if you tried running your monitor at 1920x1200 @ 75 Hz. Black port wouldn't have a problem with that.

Alright so basically here is the run down, I had it in the black port, everything's great, I had a 600watt psu and my system is totally under powered, I change the DVI port because I was like, let's mix it up so everything was ok for a bit and then bam, crashes on everything after 10 min, thought because it was underpowerd, get new psu, less crashes but still does crahs, notice I am plugged into red so I plug it into black, no more ctashes, but then I notice graphics card overheats, well the fan control is faulty so I'm getting a new cooler shipped, so I can't run anything on Max because it lags and is gross and fear of ovrrheat

You can use Catalyst to set a lower target temperature for the card. 70C and lower is great under full load.

R9 280 isn't going to have enough performance to run everything on ultra, especially newer titles but that depends on the resolution.

I stated that the problem is the fans are stuck, a bad fan controller, I think I know given I made a previous posy pon the matter and xfx reolved it, however which card do you think has the power to run evrything on ultra as you say?
