New Graphics card vs integrated

I just purchased a Dell XPS 8900 which came with a Nvidia GeForce GTX 745 4gb ddr3 graphics card. I am using it with a Dell U2715H monitor. While the monitor and card both have ports for HDMI (and do work together, but are so far a little glitchy) I'd like to take advantage of the Displayport technology which the monitor has but the Nvidia card does not. Someone on this forum stated that the integrated graphics card (which does use Displayport) on the PC should be sufficient for use with Photoshop I'm a little leary, especially since I'm going to be editing some video from Canon cameras and a GoPro. To use the integrated card it would just be a matter of going into the BIOS and disabling the nvidia card and enabling the integrated card. Another option is to purchase another graphics card that does use displayport and swap out the Nvidia GTX 745. Any thoughts on this would be appreciated.

Thanks much!

If neither the onboard card or the Nvidia are suitable you might want to look into other options but it would probably be a better idea to determine whether or not the equipment you have on hand are suitable first. Have you tried your stated options yet before considering another card?

I am currently using the HDMI connection card to monitor but having trouble with Netflix and with D/Ling Photoshop CC completely. I am going to try the PS CC d/l one more time (others have reported the same problem over this type connection) & then try the integrated card. I can't imagine the integrated card would be sufficient for the max potential of the monitor (2560x1440 60Hz). We shall see. I'll post how it goes.

Thanks for your reply ,

Michelle, does your Nvidia have Dual Link DVI-D connector on it? You should be able to use DVI DL to support 2560x1440, that's what I use with my own 27" 2560x1440 IPS monitor (Monoprice)

The Display Port-to-Dual Link DVI Adapter from Dell™ is used to connect DVI port of your Dell systems to the display port of your monitor. This product has been tested and validated on Dell systems and is supported by Dell Technical Support when used with a Dell system.

Manufacturer Part# : F856T
Dell Part# : 330-6841

Since you already have it why not just try it and see? The only reason the nVidia would be faster for video editing would be for processing, not for display, I wonder if you can use the nVidia card for acceleration and still put your screen through on-board video.

Make sure you drivers are up to date. Go to http://www.geforce.com​/drivers for more info. GeForce makes it easy to verify as they can auto update by looking at your specific hardware.

I'm confused; are you saying your CPU has integrated graphics and a displayport already on the back of your machine? If so, use it. There is absolutely no reason you shouldn't be able to run your display for any application using that port. I doubt that the dedicated GPU would make too much of a difference for your basic video editing, though if you're doing a lot of grading and heavier tasks you could benefit from a dedicated GPU. I would say cross that bridge when you come to it though and for now just make use of the displayport you already have.

This is what I'd do. The current iteration of Intel's on-board GPUs are very competent. Do you know which one it is? DVI does not carry audio and will not be HDCP-compliant. Both HDMI and DisplayPort carry audio and provide HDCP validation (and your display also has to have HDMI-compliance).

The graphics processor built into the CPU is on par with the GeForce 745(pretty weak OEM GPU designed to confuse people with impressive looking specs over actual performance). I would switch to the onboard and use display port. A quick search showed others having problems going above 1920x1080 using HDMI on the 745 GPU's. DVI-D seems to work better above 1080p on these cards.

The Dell U2715H has both HDMI and Displayport connectors and Mini Displayport connector.

• HDMI maxes out at 1080i resolution, 1920 x 1080 resolution
  
• Displayport can support 2560 x1440 resolution.
