HP Gaming Desktop 790-0010 won't display image onto Acer Monitor

[Caballero02]

Hi everyone, I just recently purchased a HP Pavilion Gaming Desktop 790-0010 and a new Acer Monitor and for some reason the monitor will not display images from the desktop while using a HDMI cable but when I connect the HDMI cable to my laptop, the image from the laptop will display on the monitor. Should I be using a DVI cable instead of an HDMI cable?

Hello @Caballero02 

Are you using the correct port? Use the one from the graphics card, not the motherboard.

Example: yours will be similar to this photo...

product number

Example this model

HP Pavilion 790-0010nt Gaming Desktop PC Product Specifications

NVIDIA GeForce GTX 1060 (6 GB)

• Form Factor: ATX (full height) PCB with ATX dual slot bracket
• Dimensions: 11.2 cm x 17.3 cm (4.4 x 6.8 in)
• Rear I/O connectors: Dual Link DVI-D + HDMI + 3 DisplayPort

you have to connect the screen to the graphics card
Normally the motherboard ports should be hidden

Berks motherboard specifications.

• 4 DisplayPort
• 5 HDMI out

It is possible so well connected to the graphics card that it is the hdmi cable which is not correct

Yes, I made sure it was connected to the port in the middle instead of the one above it but the monitor seems to still give me a "No Signal" image.

Please product number ?

If it is the right HDMi port used, you have to test another cable, maybe the one used is hdmi 1.4 for example, while you need a 2.0 ( juste example )

ANd monitor model ?

The product number is "3LA93AA#ABA" and the Model Number is "790-0010". Do you need the serial number too?

[Prométhée]

No, it's ok !

never give the serial number on the forums
The P / N number is enough with that we easily find the model :
