hd4600 Display Port flickering

PBowl — Fri, 23 Jan 2015 16:16:58 GMT

I have just bought an HP Z230T tower with HD4600 graphics. 1 x DVI and 2 X DP.

The unit box has Intel i7-4770 @ 3.4 GHz\ 500 Gb SSD\ 1Tb HDD\ 32GB RAM and a Win 8 downgrade to Win7 professional

I have three 24" monitors 1x Samsung 2494HS and 3 x ilyama E2482HS, which I would like to be able to use. alas all are DVI\HDMI\VGA. so am some what stumped.

Using two with 1 x HDMI and other via DP > HDMI active adapter, I find that the HDMI is breaking up and going blank continually.

Any-one got any ideas?

I know DP monitors would be best but I do not Game and use only for business. Anyway it might be cheaper to get 2 x dual port graphics cards than buy new monitors.

would appreciate anyone's input before buy other graphics cards 😕

What type of HDMI cable are you using? I strongly recommend a high quality High Speed HDMI 1.4 or greater cable. For example, http://www.amazon.com/AmazonBasics-High-Speed-HDMI-Cable-Supports/dp/B00870ZHCQ/ref=lp_202505011_1_2?s=audio-video-accessories&ie=UTF8&qid=1422039956&sr=1-2 this one is inexpensive and very good quality.

Thanks

I bought Belkin High HDMI Cable, high speed with Gold connectors 2m - HDMI0018G-2M and

http://startech.com/ Startech.com Displayport To Hdmi 4k Audio / Video Converter Dp 1.2 To Hdmi Active Adapter - 4k @ 30 Hz 　

to match the 1.2 DP from the HD 4600.

The only thing I have noticed is that the leads for the Monitors are DVI-D single but ports are DVI -D Dual. with 1 x DVI-I single on the HD4600

However have also tried a heavier unmarked SKY TV HDMI cable which make no difference.
