Graphics Card (DVI-D Out) to Monitor (DisplayPort In)

Hi guys

With help from @muchomurka , I have managed to build a PC centred around some old parts I had - P5K Deluxe Wifi mobo, Intel Core 2 Q6600 (G0 version), 8 GB ram and a Graphics card. This graphics card is a GeForce 8600 GTS Silent Fanless HTDP 256MB GDDR3 HDTV/Dual DVI (PCI-Express) - see pic attached and the link below it.



Asus P5K Deluxe WiFi Motherboard

I bought a cheap monitor on the bay, a HP EliteDisplay S231D. It seemed excellent and it is. However I wanted to connect one of the 2 DVI-D ports on the Graphics Card to the monitor which was advertised as having a DVI-D input socket. The monitor, when it arrived didn't have one of theses, rather a DisplayPort. Having bought a DVI-D/DisplayPort cable, I have quickly realised that the cable only works one-way, it is not bi-directional. If the Graphics card had a DisplayPort and the monitor a DVI_D port, then it would work but it does not, the other way round.

The monitor cost me only £59, less a £5 refund for the £5 cable (due to the incorrect advertising) and connecting from the Graphics Card using a DVI-D to VGA adapter which I have, to the VGA connector on the monitor, the picture looks quite good indeed, I must say. The mobo has its own sound system, so am not bothered about sound to the monitor - it only has pass-through anyway.

My question is: -

Is there a cheap way of connecting a DVI-D (OUT) to a DisplayPort (IN). If so, would I experience even better picture quality? I am aware that VGA signals are Analogue, whereas DisplayPort and DVi_D signals are Digital.

I could return the monitor - it's a 22" with a max resolution of 1920 x 1080p (which matches the Graphics Card) but I believe I would have to pay a lot more for one with a DVI-D port.

Hope someone can help

There are DVI to DP adapters, but they are active. Example: StarTech DVI2DP2 DVI to DisplayPort Adapter - with USB Power - 1920 x 1200 - DVI to DisplayPort Converter - Video Adapter - DVI-D to DP - Newegg.com

Whether such an adapter would make economic sense for you, I can't guess.

Are you really using a DVI-D to VGA adapter? That'd have to be active, too. A DVI-I to VGA to VGA adapter wouldn't have to be active, as the DVI-I port includes both digital and analog signals. (Such adapters are cheap.)

Thanks guys you've answered some of my question but not the bit that relates to the picture quality of a potential DVI-D to Displayport converter vs what I'm using - a DVI-D/VGA adapter to Displayport cable link; HP's specs are quoting identical figures for both VGA and Displayport connections.

No a converter for that price, assuming I could acquire one in the UK, would be uneconomical.

VGA analog signal & picture can be of comparable quality with digital one; however, it depends on many hard-to-measure factors - quality of cable & circuits in both graphics card and monitor. Difficult to decide, personally I'd prefer returning the monitor back for money refund because of wrong specifications. Or using different graphics card with DP out if you have one at hand or if you can buy one cheaper than dvi/dp converter.

@muchomurka Thanks buddy - thought I'd see you here There's something about tinkering with old parts isn't there? A bit like building a classic car!

Your statement "VGA analog signal & picture can be of comparable quality with digital one" does it for me as this is borne out by HP's specs for the monitor connection-wise. So I'll stick with what I've done and put it down to experience. I spent yesterday tinkering with the PC's sound - I forgot what a beast the P5K Deluxe was/is . Then I tried to sort the webcam on the monitor - that was another thing. I figured out in the end that I had to connect the PC to the monitor with a USB cable - the monitor shows up as a device in file explorer and I found some software which allows me to tinker with the monitor's PQ settings - the display is looking superb and the webcam works too. It's a backlit LED monitor and for £59 (appx $73) it does the job - my son will be impressed.

Thanks once more
