HDMI or Displayport?
I'm going to be adding an outboard graphics card to my PC. It has, one
each, a DVI-D, a displayport, and and HDMI port. My two monitors both have DVI-D ports. I know I will need to get an adapter cable of some sort to connect the second DVI-D monitor to either one of the other ports. Which one would be best the displayport or the HDMI? FYI, my second monitor also has a VGA port that is currently how it is driven. |

He will, because his new graphics card doesn't have a VGA output. My old card does, and it can't quite do 1920*1080 through its DVI port, so VGA is what I must use. And I couldn't care less. I tried both VGA and DVI with my previous 1280*1024 monitor, and could see absolutely no difference at all between the two. |

FYI, my second monitor also has a VGA port that is currently how it is driven. My DP monitor and cards can do 144 Hz. They have both DVI and DP but DVI is limited to 120 Hz. My DP drivers load after Win is mostly loaded so I cannot get into the bios with DP and use an old VGA monitor for that. DVI can get into the bios but can't keep the DVI cable plugged in because both the card and the monitor will revert to DVI instead of DP. |

I don't know if any displays were that good at the time. Mine was Samsung, a 19" TN panel which quickly developed a couple dead pixels near the bottom of the screen. Oh, look, there's another one. Then a smattering of them, and I'm starting to feel unlucky but at least they're dead down at the bottom and not stuck on bright green right in the middle of the screen. Then the backlight burned out within a couple years anyway, and I bought this wonderful LG 23" IPS monitor that is still perfect after at least two or three Samsung lifespans, and VGA is bitchen. |

I adore the snap clip on D-Port as they don't fall out the back of the monitor and/or computer. That being said, I have never had an HDMI jack come lose. I notice about a 10 to 20% better picture (clearness) with HDMI/D-Port over VGA. Myu customers notice it too, but that may be them responding to my exuberance. I would use an HDMI to D-Port converter. Start Tech excels at this kind of stuff (don't buy their USB cards). https://www.startech.com/AV/Converte...-adapter~HD2DP Make sure you have a spare USB port co-located for power. Tip: both HDMI adn D-Port will carry digital sound. Windows Nein (w10) will pick only one. It may even pick you analog sound card on your motherboard. If you go into control panel, sound, you can choose which one you want. And Tip: you have to go into your monitor setup using those annoying menu buttons on your monitor and tell it your sound source is digital. I personally adore my Yamaha speakers. -T |

FYI, my second monitor also has a VGA port that is currently how it is driven. You didn't tell us the native resolution of the monitors. DVI-D ------------------- DVI-D monitor (dual link for 2560x1600 ???) (single link for 1920x1200 ???) DisplayPort --+--- active_adapter --- VGA $20 (uses +5V on DP cable) | +--- passive_adapter --- single Link DVI-D | +--- passive_adapter --- HDMI HDMI ---------+--- active_adapter --- VGA | +--- passive_adapter --- single Link DVI-D Active_adapter have a chip inside the cable assembly or lengthened connector, that "converts" formats. The cable has +5V power for low power items, and that's how the chip is powered. There have been some adaptation devices in the past that use a USB cable for additional +5V. Passive_adapter rely on the probing of the monitor to uncover what adapter scheme is being used. Passive is "just wires". No power is used. Passive is generally used between a digital_source and a digital_destination. There might be some active_adapter devices for making dual link DVI-D, which would give sufficient resolution to drive an Apple 30" Cinema display 2560x1600 DVI-D or so. That would be a case of "digital adaptation" at high speed, and a "remapping" to make the two necessary link signal sets. If the dongle needs a memory chip and has a one or two frame time "thru_delay", the dongle will be marginally more expensive. (They can't always economically fit the RAM for a frame buffer, inside a dongle adapter, so it's a two chip solution.) If you're playing first person shooter games, you likely wouldn't do what is in the previous paragraph (too much thru_delay). The Wikipedia article for DVI will explain the resolution limits on single link DVI versus dual link DVI. ******* At low resolutions, you can't see the difference between VGA and one of the digital methods. As the resolution rises, there are reflections and ringing on the VGA coax wires which make the digital cabled version of the image look like the better option. Digital doesn't degrade in exactly the same way as analog VGA. On the video card I purchased at the end of last year, I use this. DisplayPort --+--- active_adapter --- VGA $20 (uses +5V on DP cable) The resolution is 1440x900 on a cheap monitor, and it looks fine. None of my monitors have a wealth of connectors on them, so you take what you can get here. And this is the year to stock up on adapters. Don't wait five years to go shopping for a second one, as eventually they'll disappear from the market. We're at "peak flux" in terms of the adapter mess at the moment. Paul |

That one is mainly email and a couple of status monitor programs there is nothing very demanding going on there. Right now I am leaning toward an HDMI to DVI-D passive cable. According to my research, the digital signals are all the same, with the only difference being the type of connector on each end. And like I said in a different post, no sound to worry about. |

DVI -- to HDMI is probably easier/cheaper to find. |

FYI, my second monitor also has a VGA port that is currently how it is driven. Both HDMI and DisplayPort carry sound over the wire if that makes a difference and both can do 4k (3840x2160). However, HDMI is limited to 30FPS as far as I can tell whereas DisplayPort can manage 60FPS at that resolution. |
