![]() ![]() After my last reply here, I decided to try updating the BIOS. In any physical system, where nothing is exchanged with the outside environment, entropy always increases.įinally, many years later, I solved the issue. My guess is either ASUS did something wrong with this motherboard accidentaly that made VGA not work (remember Xbox's red ring of death?) or they made VGA not work on purpose during the BIOS boot, because of corporate greed, trying to phase out VGA and push for the sales of HDMI monitors.Įither way, I'm still curious about this intrincasy. It sure seems 100% compatible with VGA in Windows 11, where it's working fine. The question that theorically it's not fully compatible with VGA as you said, made me suspicious from that start, never convinced me. A small mystery for man, a big mystery for mankind lol. Why does it have a VGA port then if it doesn't work? In terms of hardware, it's ready for VGA, the VGA monitor also works perfectly. So it boggles my mind why the motherboard fails to connect to that monitor during BIOS boot. The VGA monitor is working in Windows as we speak. You're right that when HDMI and VGA monitors are connected, the motherboard prioritizes VGA for some reason. I already tried different BIOS options like enable multi-monitor, HybridGraphics, nothing available there works. Since the motherboard only recognizes the HDMI monitor before Windows loads, how come it won't use the HDMI monitor like usual to show the BIOS splash screen if both monitors are connected? If I connect the VGA cable (have both monitors connected at the same time), none of them gives any signal and no BIOS splash screen is shown, until Windows starts loading. In the past, I already contacted AMD and ASUS asking about this issue, getting mostly ignored or inconclusive confusing answers, some representatives didn't even understand anything about hardware, so that was a waste of time.ĭuring boot, the only difference is, if I unplug the VGA cable (have only the HDMI monitor connected), I see the BIOS splash screen again, that says "ASUS in search of incredible, Press F2 to enter BIOS". Go figure why the motherboard has a VGA port if it's not completely compatible with VGA monitors. ![]() I already know this motherboard is not 100% compatible with a VGA monitor, for no apparent reason (since it works in Windows), except probably due to corporate greed. When I log on, both monitors show Windows at the same time, so everything seems to work fine in Windows 11. After that, as soon as Windows starts loading, the HDMI monitor shows image again as normal. However, when I reboot or start the computer, both monitors show no signal during the BIOS splash screen phase. I've connected 2 monitors to the PC, which seem to work fine in Windows 11. ![]()
