DP++ to HDMI cable help please

[Canexpat]

Computer with integrated Intel 530 HD card, has DP++ outputs. Trying to connect to Acer R240HY monitor with HDMI inputs.

Purchased a Cable Matters DisplayPort 1.2 to HDTV Cable Supporting 4K.

Monitor does not recognize any signal. Monitor is scanning across all inputs. Computer has all updates. I had hoped it would be simple plug and play. Any help for a simpleton?

BTW thank you for the reply!

Is that the info you're asking for?

Should be simple plug & play mate.
Is PC working fine via VGA output ??
Do you have another HDMI based screen you can try?? Standard led tv or similar?
I'll assume you tried both dp outputs ??
Cold starting from each .

Have a lenovo tinypc with same ports , I use a dp to HDMI myself , only singular issue ive ever had was I have to use VGA to get display in bios.

Yes, VGA is fine. Tried a laptop with DP to same monitor and no go. Tried both DP++ outputs from PC and same result. Bad cable?

And thank you for the reply!

Eminently possible its a bad cable mate yes (although I'm not sure what can actually go wrong with a cable)

You don't have a different screen you can try ??

Try connecting both VGA & dp cables , boot into windows with the display on VGA.
Then press either windows key+P or opens settings system/display & click the detect button under multiple displays.

If neither of these options does anything then the monitor edid information is not being passed along the cable .

DP To HDMI, Rankie Gold Plated DisplayPort To HDMI HDTV Adapter Converter Male To Female With Audio (Black) - R1140 https://www.amazon.co.uk/dp/B010SDZZ80/ref=cm_sw_r_cp_apa_oEE6ybGMN7SVM

I use one of those with my own HDMI cable rather than an all in one cable

 

[madmatt30]

Failing that do you have a native HDMI device you can try on the monitor - just to be dead certain & take the monitor out of the equation ??

Followed Acer connection instructions. Tried connecting through Settings as suggested. Tried connecting to another HDMI device. Tried both DP++ ports. Tried through safe mode. All efforts failed. So it's either the DP++ ports or the cable or me.

I'll return the cable and try the adapter you suggested.

Thank you so very much for your input and suggestions madmatt30!
