My processor doesn't have integrated graphics on it, I will try plugging in the monitor to a friends pc and see, I just ordered some new cables too lets see after it comes.....
I built my PC only a couple of months ago and it was working fine until recently I started experiencing signal drops to monitor at start up. Now this happens all the time and its really hard to work. Suddenly the monitor looses the HDMI signal and comes back on. My pc specs are:
i3-9100F
Asus Prime H310M-E R2.0 motherboard
MSI GTX 1650 Super Ventus XS OC card
16GB G.SKILL Aegis DDR4 ram
ThermalTake 450W power Supply
