Dell P2715Q for 4K@60Hz on a 5,1 MacPro with RX480

[Caesar_091]

I would like to update my current display setup (Apple Cinema HD Display 23" + DELL U2312HM 23" in pivot mode) installing a Dell P2715Q that will replace the Apple monitor (or maybe be installed as a third monitor... I still have to take a decision on this).

Are there any known issues with my setup?

Should I go for particular connection cable thinking about the 4K resolution/refresh rate or a "common" DPtoDP 1.2 cable will be good?

TIA

The Dell comes with a good DP-mDP cable, and the monitor has DP and mDP inputs.

I've found some cheap "DP 1.2" cables that in fact won't work, so get quality cables and/or a no-charge return guarantee.

Some cables are called "high bit rate" cables - those would be safer. e.g. https://www.neweggbusiness.com/product/product.aspx?item=9b-12-119-574

Thanks for your suggestion; I'll try some DPtoDP1.2 cables I already have and then I'll look for some higher quality one

have you seen the p2715q in person? I did, and decided not to get one. It is not as sharp as the Dell u series. I ended up with an LG 4K which just looked better. However I find myself running it at 1440 (which is what the Apple thunderbolt display runs) because it just looks better. I just picked up the u2715h which is the ultrasharp QHD display and I think honestly just looks better in person.

Make sure the adapter you get is an "active adapter"

Which Dell "u" series? (The "p" series and "u" series are both in the Dell UltraSharp category.)

If a P2715Q didn't look "sharp" - I'd suspect scaling or other system issues on the display setup, not a fault on the P2715Q.

I've bought a couple of dozen P2715Q monitors, and have only seen two consistent problems.

• People with older Apple laptops with integrated graphics could not drive them at 4K - fixed by buying newer Apple laptops
• People with dual or triple monitor setups who couldn't stand the low-res secondary monitors after getting used to the P2715Q primary - fixed by buying more P2715Q monitors for secondary and tertiary screens.

I think that the P2715Q is the best value on the market. Unless you need (and are willing to pay for) EIZO level color quality, I can't see spending more.

the new UP3216Q looks like an interesting option, as compared to the 27"5k which Dell are still selling here. It's a few hundred cheaper, and looks to have slightly better colour performance and response times, and none of the dicking around that the dual cable display seems to require. Has anyone managed to make that (the 5k) a reliable turnkey display yet?

Looking at the Dell Website - the p2715q is referred to as UltraHD, not ultrasharp. The P model designation puts in the Pro series, nu the U designation for the ultrasharp series. But the real tell is they do NOT give a color gaurantee on the p2715q.

It is a really nice panel, but it is not as color accurate as the U series, and depending on the video card, as to sharpness: It was on display running same card as a LG panel that was just as nice (for all I know they are actually the same panel under the bezel) at Micro Center. I put my 600 bones back in my pocket.

"UltraSharp" is a marketing name. "Premiere Color" is the gamut guarantee. "Ultra HD" is 4K.

Note for the P2715Q:

Nearly perfect color accuracy.

You can count on natural and consistent color across different mediums because each monitor is factory tuned at 99% sRGB with a color calibration factory report certifying that each monitor has a deltaE < 3. That means you get precise color coverage right out of the box at an amazing high-color depth of 1.07 billion colors. Each hue remains consistent from virtually any viewpoint with an ultra-wide viewing angle at 178°/ 178°.

The U2715H isn't 4k though so you won't get that retina quality. I had the U series and sent it back immediately.

I can't speak to hooking it up to a MacPro but my Dell has been perfect for my MBP, would definitely buy it again.

Thank you guys for your comments... very much appreciated

100% color accuracy is rarely needed. If you absolutely need it you will have to drop some serious cash, not just for the monitor, but a calibrated graphics card (like the BMD cards) and a color calibrator to adjust for drift periodically.

What about Samsung U28E590D? I pretty much cheaper... any experience with this model and RX480 on Mac Pros?
