DVI 24+5 to VGA Adapter – High Resolution VGA Converter. Get the DVI 24+5 to VGA Adapter 15-pin to connect DVI output devices to VGA displays. Supports up to 2560×1600 resolution, durable build, and plug-and-play.
What is DVI-I 24+5?
DVI (Digital Visual Interface) comes in several types. DVI-I is “Integrated,” meaning it carries both digital and analog signals. The “24+5” pin layout includes 24 digital pins and 5 analog pins. The analog pins are what allow VGA compatibility through passive adapters.
Why Use a VGA to DVI Converter?
Older monitors, projectors, or screens may only have VGA input.
Many graphics cards, set-top boxes, or equipment still have DVI-I outputs.
A converter bridge allows you to reuse existing displays without investing in new ones.
Useful in education, labs, mixed display setups, business installations, etc.
How It Works
When using DVI-I, part of the connector carries analog RGB signals the same type VGA uses).
A passive adapter simply maps DVI-I’s analog pins to the VGA pins; no digital conversion is needed if you stay within the analog signal domain.
Because it’s passive, there’s only minimal signal loss (depends on cable length, quality, and connector plating).
If your DVI output is DVI-D only (digital only), analog pins are not present → adapter won’t work for VGA.
Image clarity: At higher resolutions or long VGA cable runs, analog signals may degrade (blur, noise).
No audio – VGA only carries video.
For digital displays (HDMI, DisplayPort), this adapter won’t convert into those digital formats (you’d need an active converter for that).
Ideal Use Cases
Retrofitting older projectors or displays in classrooms or meeting rooms.
Using older VGA monitors with PCs that include a DVI-I port.
Technical or industrial equipment with DVI-I outputs.
Temporary or portable setups where a VGA display is all that’s available.
How to Use It Properly
Ensure your output device supports DVI-I analog.
Firmly plug the DVI-I male into the source.
Connect the VGA female end to your VGA cable/display.
Adjust display settings to a resolution supported by the adapter/display.
Keep cable length reasonable to avoid signal degradation.
| Specification | Description |
|---|---|
| Product Name | VGA ↔ DVI-I 24+5 Converter / Adapter (DVI 24+5 Male ↔ VGA Female) |
| Connector Type | DVI-I (24+5 pins) male; VGA (15-pin) female |
| Signal Type | Analog video signal; converts DVI-I to VGA (analog path) |
| Supported Resolution | Up to 2560 × 1600 (commonly up to 1920×1080 or 1920×1200 depending on quality) |
| Build & Material | Metal or molded plastic housing, often with nickel/gold-plated connectors for corrosion resistance and better conductivity. |
| Direction | DVI male → VGA female (i.e., from DVI-I source to VGA display) |
| Use Case | Connect an older VGA monitor/projector to a device with DVI-I output; retrofits, second-hand hardware setups. |
| Dimensions & Design Features | Standard small size, sometimes right-angle versions; generally plug-and-play; no power needed as analog signal pass-through (for DVI-I, which carries analog pins) |
Will this adapter work with a DVI-D only port?
No. DVI-D has no analog pins; this adapter uses the analog (VGA) pins present only in DVI-I (and sometimes in DVI-A) connectors.
What maximum resolution can I expect?
Many models support up to 2560×1600, but real-world resolution depends on display quality, VGA cable length, and signal strength.
Is an external power source needed?
No. Since it’s passive and uses analog wiring in DVI-I, no extra power is required.
Does this adapter support audio?
No. VGA carries only video. If you need audio, use a separate audio connection or digital interface.
Can I use long VGA cables?
You can, but long analog cables may introduce signal loss, noise, or blur. Keeping cable length short or using high-quality shielded cables helps.
