fitness88 Posted February 11, 2017 Share Posted February 11, 2017 (edited) I currently have 3 monitors [1920x1080 @60htz] with an HDMI connection and a D-Sub. I use the HDMI on all three Monitors to connect to my Nvidia graphics card through 2 DVI & 1 HDMI port. Since I only have 1 HDMI port on my graphics card I use 2 DVI to HDMI cables to connect to the other 2 monitors. With my new computer the Nvidia graphics card will have 1 HDMI, 1 DVI, 3 DP ports. Is it better to use 3 DP to HDMI cables to connect to the 3 monitors or use the cards 1 HDMI and 1 DVI port with cables I already have and just get 1 DP to DVI converter to connect to the 3rd monitor? Thank you. Edited February 12, 2017 by fitness88 Link to comment Share on other sites More sharing options...
cichlidfan Posted February 12, 2017 Share Posted February 12, 2017 IIRC, you would be best off running all three off of DP ports. This is based on a comment Skatezilla made, some time ago, about better synchronization. I don't recall the details and I am not sure how critical it is. You might drop Skates a PM and ask for details. The right answer requires knowing more about the internals of the video card than the knowledge I possess.

Thermal Posted February 13, 2017 Share Posted February 13, 2017 They are all digital connections, so there is no image-quality concerns. The issue cichlidfan is talking about is that there *might* be encoding latency differences between the three ports on the graphics cards, so when the card generates a frame for each of the three monitors, they might not be perfectly synchronized as they get streamed onto the cable for delivery to the monitor. My gut feel is that its a non-issue (particularly on the all-digital ports). There is probably a small difference if your using an analog port (D-sub) as that would need an additional conversion process. Monitors vary wildly with input latency, and lots of people run different monitors in 3-screen setups and this is the first time I've heard mention of it, so my guess is that its not a thing (although if you have a 50ms latency potato of a monitor and a 1ms gaming monitor it might be noticeable).

fitness88 Posted February 13, 2017 Author Share Posted February 13, 2017 Thanks to both of you...I'll try it with the 3 different connections because I have 2/3 of the cables already. If I see a difference I'll then consider getting all 3 monitors onto the DP. I got the 1080 card for future purchase of some sort of 3D goggles.
