The question display becomes black on a vintage Pentium 4 system.
The question display becomes black on a vintage Pentium 4 system.
I've assembled several vintage gaming systems, including 486, PIII, Pentium 4 models, and encounter a situation where certain graphics cards show the BIOS screen but then go black during startup. I'm using either a VGA with an HDMI adapter or DVI to HDMI connection. Some card/motherboard combinations work, while others don't. Many of my older graphics cards fail to function compared to newer ones. I'm curious if there might be an issue with resolution, frequency, or even the monitor not turning it off properly. Anyone have experienced this problem? If so, what solutions did they use? Thanks.
Back then, mobos offered the choice to turn on the GPU at startup or use the chipset graphics. Additionally, the dual-monitor configuration could be stored on the GPU, requiring driver updates to modify it.
Are you employing a VGA or DVI connection from an outdated GPU and passing it through an adapter that outputs HDMI? If this is the case, you might be let down if your adapter cannot manage all settings. Inexpensive adapters often have limitations and may not perform as expected (or as advertised by the manufacturer).
When working with older computers, I link the GPU’s VGA output straight to the monitor’s VGA input, just like before. Likewise, I connect the DVI output directly to the monitor’s DVI input without using any complex signal converters.
On an older PC, the initial startup screen usually displays at 640x480 or 800x600 resolution, and then the GPU typically adjusts to a higher resolution for Windows desktop use—such as 1024x768 or 1280x1024. The refresh rate can also shift, for example from 60Hz to 72Hz or even 75Hz.
Not seeing anything after the POST sometimes happens if Windows was previously configured for a much higher resolution (like 1600x1280, 1920x1200, or 2560x2048) with a different monitor. Alternatively, the GPU might be set by Windows to output 75Hz, but your monitor or adapter can only handle 60Hz.
Connecting a monitor with a lower maximum resolution—such as 1280x1024—or an adapter that struggles with higher resolutions will result in a blank screen. The available refresh rate on your monitor and adapter might not match the settings you previously applied.
I suggest using a monitor with native VGA or DVI inputs during testing to eliminate issues related to cheap video standard adapters (VGA to HDMI, DVI to HDMI). Used monitors are often affordable and may still support some of your older GPUs.
I still own several old monitors equipped with VGA and DVI ports. It makes sense to match old GPUs with outdated screen technologies during troubleshooting. Simplifying the setup can help reduce confusion.
Hi Terry, I faced similar issues with the GPU boot process. Turning off the onboard graphics and then switching the first to PCI and the second to AGP helped me get going. It seems the AGP card might have caused a slight delay before the system recognized it.
I'm using adapters and don't know if they're reliable. I bought them from Amazon and reading reviews would make me hesitate to buy anything. Lol. I don't have monitors with VGA or DVI inputs left, but I think I'll need one with VGA for testing. My monitor is brand new and only has HDMI and Display port. One system I fixed was an old XP machine used for CAD and Dyno tuning. After a repair install with updates, it worked fine, but when plugged into his old LED monitor we had a problem—we fixed it by forcing the monitor to boot only from VGA, which would sometimes go black. I've encountered many issues when mixing old hardware with new monitors. Thank you for your response.
