display won't appear using my GPU "no signal"

[Joaldi]

So I recently build a gaming rig
CPU: AMD FX-8350 4GHz
GPU: GTX 1050 4GB
PSU: EVGA super NOVA 650 G1 80+ Gold (Fully Modular)
Mobo: ASUS 970 Pro Gaming/Aura
RAM: 6 GB DDR3
Storage: 1TB HDD WD Blue
When I plugged the DVI-I and HDMI to the monitors and turned it on it displayed no signals.. When I disconnect them it turns to complete black. Everything is running, GPU, CPU, PSU what should I do
