4 out of 5 eggsInput lag is not THAT bad

Pros: This monitor provides, hands down, the best picture of it's price range. Perfect size.
Great brightness level.
Beautiful color.
Joy to work with.

Cons: Input lag is present but virtually unnoticeable in most scenarios IMO.
OS may need to be tweaked for new resolution, but that's true of all 4K monitors.

Other Thoughts: I see a lot of reviews bashing this monitors input lag, stating it's unacceptable. I didn't even notice it until working with some image editing that required intense precision. For things like gaming, unless you're running full 4k and NEED 60fps, it's perfectly acceptable. I enjoy 60fps gaming as much as the next guy but honestly even at 4K it was by no means 'unusable', heck, it could barely be considered 'choppy', but maybe I'm just more used to 34fps. I can't give it a full 5 because the lag can be agitating for some people, but for the price this monitor is fantastic.

4 out of 5 eggsHigh resolution, low price, marginal for video

Pros: The low price attracted me to this monitor, and indeed it is functional and very sharp, while cheap.
Also, the stand has a convenient pivot, so if you want to try running in portrait mode this is a good monitor for that.
Furthermore, it is a very bright monitor (at least compared to the 8-year-old one I had before).

Cons: The lighting of the screen is a bit uneven, with some noticeable brightening at the very edge of the screen.

Video leaves something to be desired, as there is generally a frame tearing line or two across the screen, even with frame synchronization turned on. I do not know if this is a bad video card or driver interaction (ASUS GTX 750 Strix on Linux using the nVidia proprietary binary drivers) since I don't have another computer capable of driving this thing properly.

Games with lots of movement on screen will also show the tearing problem. For things like Kerbal Space Program I find it manageable, but it does leave a lot to be desired.

Also, the pixel pitch is so tiny that you'll find yourself fiddling with a lot of OS and application display options in order to not be nose-close to the screen. Not all websites render well when you turn up the font size.

Other Thoughts: It's a good starter 4K monitor, and perfectly usable for a lot of desktop stuff. It's a joy to have this much desktop space. If you want a good gaming setup tho, you'll want to look at a different monitor.

1 out of 5 eggsHUGE size / res and decent color not worth the input lag

Pros: nice size and picture for static images, some users say that video looks pretty nice (although, cant verify). cheap.

Cons: input lag forces me to slow down my movements when I approach where I intend to click (so I don't over-shoot) and requires much more concentration than it should... and actually gets exhausting after a full day of CAD modeling.

wouldn't recommend for CAD use, don't even think about it for gaming.

couldn't get it to display 1440p (only option to maintain aspect ratio is 3840x2160, 2880x1620, and 1920x180) but that might be a problem with my video card - I bought a pair of these and usually only run one because of intermittent syncing issues that will cause both screens to flicker like crazy (but again, this might be caused by the computer, not the monitor). I am certain that the input lag is not caused by my computer, see below for conformation from DELL:

From DELL rep "Due to the hardware architecture, the mouse lag is a result of the P2815Q requiring 100 ms to process video data. If you have this complaint, your only recourse is to return the monitor for refund. Outside of the initial 30 days from the invoice date, it will take manager approval to get a refund."

not sure how you could call it a 5ms response time if you need 100ms to process a frame... As I said in the 'pros' apparently the delay isn't as noticeable when you are watching video because all the frames have the same 100ms delay so things are smooth until you need to interact with it.

Other Thoughts: It seems like DELL tried to keep the costs down by using a lower end processor... what they ended up making was a cheap piece of junk, if I wanted something cheap I would have gone with an off brand.

4 out of 5 eggsExcellent 4k Monitor for Price. (no speakers)

Pros: Fantastic monitor for a programmer or for editing photos.
Excellent picture quality.
Well designed on the outside.
Internal USB3 hub is surprisingly useful and clean.
Can do 1080p@60Hz.
Suprisingly lightweight and the stand is well done, also looks good rotated.

Cons: Can only do 30Hz at 4k resolution.
This isn't really an issue for gaming or movies, which are fine at 1080p resolution.
But some people find the 30Hz mouse lag annoying.
Also, this monitor DOES NOT HAVE BUILT-IN SPEAKERS, despite the "Built-in Speakers" in the newegg description.

Other Thoughts: Please fix the description: this monitor does not have built-in speakers. It does have pass-through audio output, and there is a USB-powered sound bar that snaps on which you can buy separately.

1 out of 5 eggsHorribly slow

Pros: Cheap for a 4k

Cons: It's too cheap for a 4k. The display lag makes this screen essentially unusable. You can move a window from this screen and see the window on the laptop screen at the same time as on the desktop screen - it's that slow. You have to circle things with the mouse to even click on anything. It is essentially unusable.

Full resolution was not possible - Dell Laptop (M6800 Precision with AMD FirePro video card, Dell supplied cable, Dell display - the laptop can only do 2048x1536.

1 out of 5 eggsWorthless

Pros: Big screen hi Rez

Cons: Super low refresh rate makes it worthless for everything except looking at photos. I'm a gamer and should've known better. I need to rma. Also 4k is out of reach even for a gtx 780ti. I'm gonna get a 1440p monitor instead. I think that is the sweet spot right now

5 out of 5 eggsDell is the way to go for very high resolution monitors

Pros: I got Dell U2713HM almost a year ago (2560x1440). the quality was not only good, it was flawless, I recommended to my employer to buy around 10 of these, especially for the price. None of the monitors showed any problems (and it's been 10+ months now).
Now I do want to switch to this model, due to the resolution, and the Dell quality I've been trusting for very many years. Other manufacturers of monitors with similar resolution just don't do the job good enough to create something that has absolutely no problems. I'm own a few ASUS and Acer monitors, and none of them hold the candle to the Dell monitors, whether it was 24" 1920x1200 model, or my current 2560x1440 one. the value for functionality and quality (crispiness of image, contrast, color reproduction even for models not targeted at graphical designers, quality of manufacturing) is peerless in the industry, once you can wait until Dell drops initial sky-high pricing.

Cons: can't think of any. couldn't think of any for the past 10 years. not even a single dead pixel.

Other Thoughts: I really do want to replace my current U2713HM with one or even better, two of these.

4 out of 5 eggsDell P2815Q

Pros: awesome stand, telescopes, flips
not too big not too small
4 1080p's worth of real estate!
The OSD Menu is awesome!

Cons: backlighting is not too strong, I have to dim the lights around to be able to see the text (I am a programmer so I use it to remote into VM's to do developement). There are several excellent built int settings to pick from that are more than sufficient, but you can customize it. I wish it was a 32" so the text would be a wee bit larger. I would not trade it and now cannot live without it!

Other Thoughts: I love the monitor - wish it was a 32' for the same price! Love the stand ...
