Dell P2715Q and P2415Q 4K IPS Displays

[rdav]

...And, HDMI 2.0 was ratified almost two years ago, and yet, nobody supports it yet (on monitors-- I do see TVs advertised with it.)

There seem to be a few UHD Monitors that now sport HDMI(2.0) - Eg. The Viewsonic VP2780-4K and the Acer S277HK. [ http://4k.com/monitor/a-review-of-t...h-4k-ultra-hd-3840-x-2160-widescreen-display/ ]. Thou the Acer has no Vesa-Mount, which is an odd omission.

Thanks campyguy. I should clarify that my concern is the opposite --- i.e., my issue is not ambient light reflection due to insufficient AG; rather, it's avoiding the grain/sparkles that come with too-aggressive AG (this is particularly visible on white backgrounds). I think the grain/sparkles are caused by a diffraction effect from the monitor's light passing through the AG; consistent with this, it's easily seen in a darkened room. Might you be able to comment on that for the BenQ vs the Dell?

Also, any info on whether the 27" BenQ will do 60 Hz via SST? I assume it will -- it's mostly the earlier 4K monitors that were limited to MST at that frequency. [MST is a real problem with Macs.]

Hmmm, that's a bit of a tricky question to answer - BenQ uses a few different means to achieve "anti-glare" in the BL3201PH, and the 27" reads the same on the spec sheet. The simple answer is the AG is not too aggressive, in that it's not even noticeable at low-to-medium light levels. Keep in mind that the BL3201PH (and BL2711U) are designed to be "CAD/CAM" displays - they're even certified for Solidworks out of the box.

I offer "complicated" because BenQ uses "modes" (CAD/CAM and multimedia) on these two displays and also 4 proprietary "blue points", the latter available on the OSD menu for office, surfing, multimedia, and reading - they're different than the "profiles" we're used to. Heck, the BL3201PH even has an autopivot mechanism built-in - no more futzing with the Displays Pref Pane!

The way BenQ has addressed "workspaces" kind of reinvented setting up a display for me. A long time ago, I forked over some serious coin just to get one of those huge Radius Pivot CRT displays (gawd, I hated moving that thing!). The AG on the display seems to work with the different modes and blue points for that "perfect" coating. I'm totally anal about how things look - the AG on the P2715Q is pretty good for what I need. But, I've already considered selling my Dells when the new BenQ comes out and eating the difference. I prefer the viewing experience of the BL3201PH over the P2715Q, and I can't wait to see a 4k 32" display from them for CAD/CAM work!

The new BenQ's specs include HDMI 2.0 and DP 1.2 (and DVI-DL too!) - the spec sheet on their web site only states DP 1.2 - so there's likely only one DP port, but I'm guessing here - they're offering 4k @ 60Hz, and I'm also assuming that they're getting that over both HDMI 2.0 and DP 1.2. I'm assuming it's SST - my vendor doesn't have any detail more than that, but he's a vendor (he could be selling shoes next month for all I know...).

Hey guys. Just got the P2415Q for my mid 2014 15" MBP with Nvidia graphics. Curious if anyone has any of the following issues with it (or is it normal?):

1. When it goes to power save mode (or during a brief period while it's being turned on), there's a very slight squealing sound coming from it. Doesn't happen every time, but pretty often. Doesn't happen during normal function.

2. While looking sideways at the monitor, I noticed there's a small gap between the panel and monitor's left and right bezels (about 1mm wide, enough that I can see the LEDs inside). I tried to press gently on the panel and it appears to move in and out slightly. See photos: https://www.dropbox.com/sh/tpn09d6rhbq9dtt/AACPSnE773bEGNLVAlU79LRua?dl=0

Thanks...

Have someone tried, if SwitchresX working properly on El Capitan?

I do not have either of these issues.

Save bucks by ordering from B&H, or buy from Dell?

Which option gives the best chances for dealing with warranty issues such as dead pixels, or other screen quality issues?

 

[amativos]

Thank you. I am returning it for a new one.

Wonder if my problems might be that it is a rev a0 and some of the driver issues are the DP signal sync problems... Twice now I powered on my monitor when in yosemite and it didn't sync. I had to pull the power cord and then it will get a display. I don't put the MacPro to sleep but I do power off the LCD every night...

Should I try and open a Dell support ticket?

My computer is on 24/7 and I put the monitor to sleep after 15 minutes of inactivity.

I have had to disconnect power to bring back my Mac desktop after the monitor went to sleep once.

There has been maybe about half a dozen times when I've had to cycle power via the power button on the monitor to bring back the Mac desktop after sleep.

What rev is you display?

 

[pastrychef]

What rev is you display?

A01

I bought 3 of these displays (1 24 inch, 2 27 inch) "Rev 0" displays for my small company, and all 3 were returned. Dell replaced them with "Rev 1" (A01) displays. I've bought 3 more A01 displays. All 6 of the A01 displays have been flawless - so far. Hold on, I need to find some wood to knock on. Yes, so far.

I don't see a service tag number, how did you initiate the replacement, do you have to have purchased from Dell?

 

[campyguy]

The service tag number isn't on the P2415Q (which is the one I think you own), which is a PITA - you'll need to call Dell (or the reseller you purchased from) and reference the Serial Number (under the bar code). For some reason, Dell put the Service Tag number only on the P2715Q, next to the Serial Number and ports array.

I purchased mine directly from Dell, so I wouldn't have to deal with resellers - Dell seems to be far more responsive to direct buyers as they shipped replacements to me and all I had to do was put the faulty displays in the shipper boxes, and the return charges were taken care of by Dell. I kept reading online that buyers who went through resellers had to go back to the reseller and they handed dealing with Dell - and you'd be without display for who-knows-how-long, with the exception of Amazon (but Amazon was out of stock when I pulled the trigger each time...). Good luck!

I'm looking for a second 27" monitor to accompany my existing U2713H. It'll either be the P2715Q or another screen 2713H to match. I'll get them for approximately $740 (4K, 160ppi) or $840 (1440p, 100ppi) AUD. The mismatch will bother me for a little while, but it's a little cheaper than buying a matching screen.

Could you actually write code at native 4K, or would I end up squinting too much and end up switching to scaled 1440p anyway?

If anyone is interested, Dell Outlet has a few P2715Q 4K monitors with 30% off using coupon code "%MONITOR30". $342.30 USD.

UPDATE: Those went fast. Gone.

I would never purchase a refurbished monitor for fear of dead/stuck pixels.

I have two and they look perfect. Cost me $250 each. Plus, Dell has a return policy if you find you are unhappy with your purchase. What do you have to loose, other than paying more that you have to?

(not to mention, what guarantees a new monitor won't have bad/stuck pixels?)

 

[pastrychef]

My thinking is that a refurb was returned for a reason and I fear that the odds of flaws are higher. Even if they have a great return policy, I rather not be bothered by it.

Of course, nothing guarantees that a new monitor won't have flaws, but I choose try and reduce the odds of that happening as much as possible.

My guess is most are returned due to disappointed Windows users who find that Windows scaling sucks compared to Macs. Their loss is my gain.

I just bought the P2715Q (A00) a week ago from a local retailer. I have it connected to my late 2013 MP 6 core, 32 GB memory D500; running 10.10.3. It connected up and worked fine - got 4K at 60 Hz with basically no problems. Ran through all the scaling settings which all work - not sure which I like best.
But, after letting my Mac go to sleep (I normally turn the monitor off, but not the Mac) then powering on the monitor and wakening the Mac I am experiencing some strange mouse behaviors. After wake up I get a character overlay on my mouse pointer. Varies as to which one, but they are different mouse pointer characters on top of the normal arrow. See the the photo:
https://dl.dropboxusercontent.com/u/26941868/IMG_0773.JPG
The mouse works fine, no delay and you can still point and click, but the overlay character travels around with the mouse pointer. Typically after using the system for a while the overlay character will disappear suddenly and be normal until I wake from sleep again.
Then I noticed that on certain websites (using Chrome my normal browser) I get strange mouse trails as I move the mouse around. They build up, then suddenly disappear, then start again. They don't show immediately when you mouse over the site, but happen within a few seconds. Watch the video:
https://dl.dropboxusercontent.com/u/26941868/IMG_0774.MOV
I have reset the PRAM on my Mac; deleted the mouse and trackpad plists; removed some software that I thought might be a problem; ran diagnostics on my Mac (no problems), but the situation persists! Tried all scaling options and they all produce the problem. Can't figure it out and am thinking I'm going to return the monitor while I still can - got a few more days.
Any ideas would be greatly appreciated!

Str8aero:

Wow. I've never experienced either of those anomalies. My only guess is that it's a driver issue. Have you tried using Windows? Is everything normal?

 

[Str8aero]

I agree I have some incompatibility... I just can't figure out what it is! I don't have a Windows system to try it on.
I am a photographer and I do have a Wacom Intuos tablet attached. But the problem is there whether it is on or not - and I did reinstall the Intuos drivers/software. I don't want to give up my tablet so the monitor has to work with it.
Otherwise I have the Apple Magic mouse and a wired Apple keyboard.

How is the latency on the Dell P2715Q?
The main reason I returned the Asus PB287Q was that on highest resolution through DP 1.2, the latency was so long that I had trouble directing the cursor at small targets

I had a similar issue with my Mac when I was using my previous monitor (a Korean 2560x1440 27"), but I switched out my mouse with a higher dpi mouse, and the problem resolved itself. Since I now have my P2715Q's in place, I have not noticed any change in how my mouse works. I did have a P2815Q previously, and did return that for a laggy mouse, but that monitor only works at 30hz, compared to 60hz for the P2715Q.
