| Hello, just joined the forum after purchasing parts for my first PC. I have an ASROCK b650i itx motherboard but am having issues getting it to boot when the hdmi cable is plugged into an external RTX3050 low profile graphics card. when plugged into the onboard hdmi port motherboard boots |

If you boot from the iGPU (onboard) can you switch to the RTX3050 once windows loads? -------------

Is the RTX3050 installed inside your system or is it an eGPU (in it's own enclosure outside of the case)? I just noticed you said "external GPU". If it is external then this is normal operation. The UEFI lacks driver support for external GPUs, this would be highly impractical with the amount of space it would take up on the BIOS ROM. As soon as the OS loads and detects the external GPU things will work as normal. If the system won't boot at all without a display connected to the onboard output then you can try hooking up a second display cable to your monitor, most support more than one input. This is the price we pay for external GPUs, it can require some messing around to get things working. If it is an internal GPU (I suspect this is the case given you said low profile), then try different display outputs from the card. Some GPUs will have a preferred output and won't output a display until windows if it's not used. If that still doesn't get things working then check page 63 (67 in the PDF) of your https://download.asrock.com/Manual/Software/AMD%20B650/Software_BIOS%20Setup%20Guide_English.pdf" rel="nofollow - software/BIOS setup guide for the UEFI settings to do with your primary display output. -------------

thank you @Xaltar and sorry about my incorrect terminology, by external gpu i meant a graphics card plugged directly into the motherboards pcie slot, the internal i was referring to the motherboards own hdmi socket run from the ryzens internal gpu I have the motherboard bios set to prioritise external gpu thinking that meant the graphic's card so is this incorrect? i also tried the display in both hdmi sockets and the display port socket and none of them worked |

Unfortunately I don't own any 600 series boards so I have no idea how the BIOS is laid out and what settings there are. Take a look through all the settings under "graphics features" and see if any of them are relevant. Maybe one of our members here knows the right settings to look at. Failing that, do what I do and try different things until something sticks. You don't need to play with any voltages/dangerous settings for this so a simple clear CMOS will resolve any issues that could arise. It could also be that your GPU doesn't recognize the display with the cable you are using. If you have other cables you can give them a try. It may want a newer standard cable than the one you are using. The motherboard will be more forgiving with that than a dedicated GPU for compatibility reasons. -------------
