Connecting Samsung SyncMaster 931bw Monitor to MSI GTX 660 Gaming via VGA-DVI-D Adapter

Best answers

Can I connect a Samsung SyncMaster 931BW monitor to an MSI GTX 660 Gaming with a DVI-D dual-link port using an adapter?

Use a DVI cable instead of a VGA-to-DVI-D adapter, because DVI-D carries only digital video while VGA is analog, so a passive adapter will not work [#16810137][#16810275] The thread notes that the Samsung SyncMaster 931BW has a DVI input, so the simplest solution is to connect it directly with a DVI-D cable [#16810275][#16810513][#16810572] Several replies say adapters are unnecessary and that a DVI cable is cheap and easy to buy [#16812288] If you insist on using the VGA input, you would need a proper converter rather than just a simple adapter, but the recommended route is direct DVI connection [#16812288]

    I doubt it. Dvi-d only gives a digital signal, while VGA transmits analog.

    Yes. Why combine? Is the entrance? Is. Does this match on the card? Yes. Just make sure it is a dvi-d cable.

    I have a problem with getting such a cable. Behind is a displayport cable for dvi d. The graphics card has a displayport port, and the dvi monitor has d. Would it work?

    It won't connect unless it breaks the pins.

    Why not connect? The card and the monitor have DVI-I and there is no problem.

    The DVI-I to DVI-D cable will not connect, because where will the additional pins come in?
    The DVI-D cable for the DVI-I input is already connected.

    PS. The cable costs a few to several zlotys and is available EVERYWHERE!

    Don't pay anything because you would have to salute.

    DVI-I connector - can send both digital and analog signals.

    The card and the monitor have DVI-I connectors so no matter what cable it purchases, it will work.

    To conclude: Adapters are not needed (unnecessary cost) - go to the store or buy a DVI cable on the allegro.
    Of course, you can use the DVI-> D-Sub adapter and connect the card with the monitor with a D-Sub cable - but it is always an analog image so in principle it is worse than digital, although with this monitor and using a good D-Sub cable you will not feel the difference.

    I have already used the Dvi I and HDMI connectors on the card. The problem is getting a dvi d to dvi d cable. The seller recommended a displayport to dvi d cable.

    You haven't written about several monitors.

    Of course, this choice may be the best because either both DVI sockets or one of them + HDMI work interchangeably.

    For Eyefinity ie 3 monitors there is usually DVI + HDMI + DP.

    It would work such a combination of displayport cable for hdmi and then adapter with hdmi to dvi d. I ask because ordering dvi d cable for dvi seems to make no sense to me, due to the future the displayport cable for hdmi can always be useful someday.

Topic summary

✨ The discussion revolves around connecting a Samsung SyncMaster 931bw monitor, which has a VGA input, to an MSI GTX 660 Gaming graphics card that features a DVI-D dual link output. Users express skepticism about using a VGA-DVI-D adapter due to the difference in signal types (analog vs. digital). It is suggested that a direct DVI-D cable is the best solution, as both the monitor and graphics card have DVI-I connectors, which can transmit both digital and analog signals. Some participants mention the possibility of using a DisplayPort to DVI-D cable, but emphasize that a DVI-D to DVI-D cable is preferable for optimal performance. The conversation highlights the importance of ensuring compatibility between the connectors and the types of signals being transmitted.

FAQ

TL;DR: Use 1 direct DVI cable to link the MSI GTX 660 to the Samsung 931BW; “Adapters are not needed.” [Elektroda, Kasek21, post #16812288]

Why it matters: This FAQ helps PC builders connect a VGA-era monitor to a GTX 660 without image loss, confusion, or wasted adapters.

Quick Facts

Can I connect a VGA‑only monitor to a DVI‑D port with a cheap adapter?

No. DVI‑D outputs only digital video, while VGA needs analog. A passive adapter cannot convert formats. You would need an active converter, which adds cost and complexity. “DVI‑D only gives a digital signal.” [Elektroda, daminek1234, post #16810137]

Does the Samsung SyncMaster 931BW actually have DVI?

Yes. The 931BW includes a DVI input and supports 1440×900 native resolution. Use a DVI cable from the GPU for the sharpest image. This avoids analog signal loss and simplifies setup. ["Samsung SyncMaster 931BW specs"]

What’s the simplest working cable for GTX 660 → 931BW?

Use a direct DVI cable between the card and the monitor. “Adapters are not needed.” This gives a clean digital path and avoids compatibility issues. [Elektroda, Kasek21, post #16812288]

Should it be DVI‑D or DVI‑I cable?

Either will physically work if the connectors match; the link used is digital. The key is that the GPU and monitor DVI ports align. If the socket is DVI‑D, use a DVI‑D cable for a guaranteed fit. [Elektroda, Kasek21, post #16812241]

Will DisplayPort to DVI‑D work from the GTX 660?

Yes, a DP→DVI‑D cable can work because the card supports digital output over DP. This is handy if your DVI ports are occupied, as noted by the forum guidance. [Elektroda, Kasek21, post #16812191]

Can I chain adapters (DP→HDMI, then HDMI→DVI‑D)?

Chaining may work, but failures are common. Signal integrity and handshake issues can appear. The forum could not confirm such a chain and advised testing. “Nobody will answer you until you check it yourself.” [Elektroda, Kasek21, post #16814983]

Is VGA (D‑Sub) acceptable if I already have that cable?

You can use DVI→VGA with the right hardware, but it yields an analog image. The expert noted digital is preferable, though differences may be small on this monitor with a good cable. [Elektroda, Kasek21, post #16812288]

Quick how‑to: connect GTX 660 to 931BW the right way

  1. Power off PC and monitor.
  2. Plug a DVI cable from the GTX 660’s DVI port to the 931BW’s DVI input.
  3. Power on and set the monitor to DVI input; select 1440×900 in Windows. [Elektroda, Kasek21, post #16812288]

What if both my DVI and HDMI ports are already in use?

Use the GTX 660’s DisplayPort with a DP→DVI‑D cable to the 931BW. This avoids reconfiguring other displays and keeps a digital path. [Elektroda, Kasek21, post #16813042]

Why didn’t my DVI‑I to DVI‑D cable physically fit?

A DVI‑I plug has extra analog pins that a DVI‑D socket lacks. The reverse—DVI‑D cable into DVI‑I socket—fits fine. Match plug to socket type to ensure insertion. [Elektroda, daminek1234, post #16812241]

Do I need an active converter for this setup?

No active converter is needed when connecting DVI or DP to the 931BW’s DVI input. Active conversion is only for digital‑to‑analog (DVI‑D/DP to VGA). [Elektroda, Kasek21, post #16812288]

What resolution should I set after connecting?

Set 1440×900 at the monitor’s native 16:10 aspect ratio. This ensures pixel‑perfect scaling and clear text. It’s the panel’s native mode. ["Samsung SyncMaster 931BW specs"]

Is a DVI cable expensive or hard to find?

No. The forum notes DVI cables are cheap and available “EVERYWHERE,” costing only a few to several zlotys. Availability is broad online and in stores. [Elektroda, Kasek21, post #16812262]

Edge case: Why does my screen stay black over DP→DVI?

Some adapters need power or have handshake quirks. Try another DP port, reseat connections, or use a single DP→DVI cable. If chained, remove the chain first. [Elektroda, Kasek21, post #16814983]

What’s DVI‑D vs DVI‑I in plain terms?

DVI‑D carries digital signals only. DVI‑I can carry digital and analog in one connector. For the 931BW, use the digital path for best clarity. [Elektroda, Kasek21, post #16812288]

Will image quality differ between DVI and VGA on this monitor?

Digital DVI avoids analog noise and drift. The forum notes VGA can look close if you use a good cable, but DVI is the clean choice. [Elektroda, Kasek21, post #16812288]
