Dell U2515H

What is that grid on the screen? Horizontal and vertical lines / squares...?

That tint looks quite bad, try changing the color temp preset, gamma etc. or change the RGB levels (lower green and red and leave blue at 100) use it for approx 100 hours and if the tint is still there I would return it.

I guess it's some optical effect introduced by my camera (moire or something like this). I can't see any lines or squares on the actual screen. Solid color patches (whites, greys) are actually a pleasure to look at - so silky and smooth. It's probably because the black interpixel grid which is typical for 1080p IPS panels is almost invisible here. Pixels are smaller so is distanance between them.
Jaggies and color halos around letters are also only visible on the photo.
I can't see any crosshatching patterns, not even a hint of it.

As for the tint I've tried almost everyting - can't get rid of it. It's really, really annoying when working with documents.

Yeh I would give it a few days of use and see if it goes (but probably won't) and return it for another one, my TV has a bit of a green patch on it but its not used for web browsing etc. so I don't notice it much. Cannot decide if I should get a 25" for £270 or go for a 27" at £415... The 2515 looks like the better screen compared to the 2715, more contrast, faster pixels, higher PPI etc.

i use and noticed nothing so far. maybe it is " using the USB hub in a daisychained setup"?
 
Has anyone transitioned from a 24" 1920x1200 monitor to this 25" for productivity work (not gaming)? If so, what are your thoughts? Thanks.
 
So what would you guys recommend, this one or the P2415Q as an upgrade from my 2209WA? general desktop use and some movie watching. My wife will use a lot of Illustrator and Photoshop on it as well. Price difference is 6000 rupees or 100$ here in India.

I went from a 30" 2560x1600 to this 2515h. Despite the smaller desktop area, productivity actually increased given the improved ergonomics. The gain in productivity by going up in both screen size and resolution will be massive: not onlywill you fit more stuff on the screen at the same time, but you also lose less time shifting windows

To be safe on the productivity side, grab the new dell 2416, which is about 10% cheaper while being more effective for triple portrait setups.

Can anyone here confirm that this monitor has no issues displaying the full rgb range with a 2012 Mac mini? (HD4000 graphics with mDP cable) I had to return the S2715 (1080p) due to it having only Hdmi input and Mac detecting it as a "television" 16-235 range.

I happen to have a 2012 Mac Mini so I can check that but it will have to wait until tomorrow.

I used the U2515H with a 2012 MacBook Pro, which also has Intel HD 4000 graphics, and I had to use a Ruby script to create a display overwrite in order to get full RGB. The problem is the same with DP as you had with HDMI, but it's very easy to fix.

I thought that Nvidia have fixed the RGB problem in recent drivers? There is now a drop down box in the main section (and video section as well) of the driver control panel to select 0-255. Does this not work properly or something? Or not work with DP?

I see this in the "Adjust desktop color settings" section of the Nvidia Control Panel. On my Win7 PC connected by DP, it was correctly set to 0-255 by default. Switching to 16-235 did indeed make the white part of windows very noticeably less white, so I'll know what to look for when I try the monitor on my Mac Mini tomorrow.

I'll point out that you can disable DP 1.2 on the U2515H in its OSD menu; doing that sets it to DP 1.1, which may resolve issues with Macs or PCs that have only have DP 1.1 (which, I think, is most likely on any that have Intel HD 4000 graphics). I will see if doing that makes any difference in my testing tomorrow.

typical apple user behavior: blame the other brands products for an error on Apple side:rolleyes:.

This case is even worst, because it is an error on the OS driver side of hardware that works flawlessly under windows. To make matters worst: 3 years after the product launch, it is still not solved by apple :mad:, even if the fix requires a minor software tweak . The level of incompetence required to make displayport NOT work properly with a native DP monitor is out of charts.:eek:

Apple sucks, nothing new here, move along.
 
I have the U2515H hooked up to my Mac Mini 2012 running Yosemite 10.10.2 using DP. Before I did that, I studied lagom.nl's black level page carefully, comparing how 0-255 and 16-235 looked on the PC because it was simple to use the NCP to switch between the two. On the Mac, I think it looks a bit different from the PC 0-255 setting, but this is probably because I haven't done any calibration on the Mac; the first black square definitely looks the same as 0-255 and the whites are very white and don't look washed out. Disclaimer: I am not a professional color editor so my observations may be unreliable, but it looks good to me on the Mac and 16-235 on the PC definitely did not look good.

In System Information > Hardware > Graphics/Displays, Television is reported as "Yes", which seems alarming, but in System Preferences > Displays > Color > Open Profile (opening the Dell U251H profile) Space is shown as "RGB".

In the monitor's OSD, in Color > Input Color Format, it's set to RGB instead of YPbPr and Gamma is set to PC instead of MAC.

I don't know what else to report here. Is there a test method that can tell me if it's doing the wrong thing? Because to this layperson, it doesn't look wrong.

Edit: fiddled a little bit with the monitor's OSD. Setting the monitor's Input Color Format to YPbPr made the blacks turn bright green, very funny. Setting the monitor's Gamma to MAC instead of PC decreased the gamma (as seen in lagom.nl's gamma page) from 2.4 (48%) to 1.95 (48%). Again, this is without doing any calibration on the Mac.

I noticed the same "Television: Yes" when I switched back to the Benq BL2411 that I normally use on my Mac Mini, so I used the ruby script fix that Lava Lamp Freak linked to above. After doing that, it does show "Display with forced RGB mode (EDID override)" in System Information's Graphics/Displays, so it's on, but I'm damned if I can tell any difference on the BL2411. Lagom.nl's black levels page looks the same, text in Finder and Firefox looks the same. Switched back and forth between the fix and without the fix several times, and I can't find any differences.

I guess I don't know what I'm looking for.
 
I ended up returning the S2715 and ordered a U2515. I looked into running the script but didnt work and gave up. Hopefully the mDP connection will allow the full RGB range and no other issues. Looking forward to the extra resolution and will likely need to adjust to everything being scaled down, but I have reading glasses and can scale in the OS.
 
I return 2 Dell 2515... 2 have really bad color uniformity, where one side is warm, and the other is cold.

Whats the best way/image to check for uniformity? I just received the u2515 today and cal'd it using the color cal tool in OS X and tried the lagon site. Mine looks quite good but still need to give it a once over. I really love the ease with which it cranks out the lumens. And I didnt need to scale up too much.

Just open any program or a documents with pure white background in full screen mode - if any of the corners has yellowish/purplish tinge obviously different from other corners - it's bad uniformity.
But I guess you don't have any, you would have noticed it right away

Are you connecting it to a MacBook? If you compare the full screen white image it should be easier to spot.
 
I have just sent back third 2515 because as all previous it was turning itself off/on even more frequent than the previous pieces, + it was the first one with real bad uniformity and one dark corner.

No, mac mini 2012 (HD 4000 intel graphics) using the thunderbolt port (mini display port). Just got back from a trip and checked the uniformity just now. Seems to be pretty good, but I'll bet if I used a meter it would show something. I don't see anything obvious as other have. I am very happy at this point, nice resolution but text not too small after scaling web pages (Chrome set to 110% or 125%).
 
Does the U2515H have a service tag? Dell has previously stated that 24" and smaller displays don't, but that was written during the time there was nothing between 24" and 27".

what is a "service tag"? The U2515H comes with the calibration report from the factory, which means that there was plenty of time during QC to double check for dead/stuck pixels.
 
Does the PPI of 1440p at 25" look significantly better than 1440p at 27"? Or is the larger screen size of 27" better? I was thinking of getting one of the 1440p 144hz IPS screens... But then this Dell is almost half the price! Only 2" less and other than that the specs look good.. For example 1440p at 25" with 2x AA would have almost no aliasing where 1440p 27" might need 4xaa?

My U2515H has a service tag on the bottom of the back of the monitor, with a serial number and the revision number (A00 in my case). Looks like the rule is service tags on monitors larger than 24".

Edit: having actually gone through the process of replacing the monitor, I now know that a service tag is a number that is separate from a serial number. I did not have a service tag number on my U2515H.

It's not going to have much of an impact on AA. To quote someone else somewhere else, "4K is pretty much 'free' MSAA which is somewhere between 2x and 4x in effectiveness." If your choice is between 25" 1440p at 60Hz and 27" 1440p at 144Hz, it's all about the Hz.

It's a code that Dell puts on their more premium products that makes any dealings with warranty a lot simpler. QC may or may not be checking for dead pixels during calibration - it's definitely not a given since the latter process can be largely automated, but even if they do there still seems to be a reasonably high chance of the on/off or uniformity problems so less troublesome warranty procedures are certainly nice to have...

I went from 2x 1920x1200 (U2410) to these and could not be happier. The extra real estate and clarity in nearly the same size package was well worth it. I really wanted to do 3x, but that's an insane amount of desk space.

27" 1440p @ 144Hz is almost twice the price, because it worth it market wise- it is the nirvana of gaming monitors, and leaves nothing behind when working.

If you are happy wit the value inside the U2515H, you will be glad to hear that the P2416D is selling on Europe for 259 Euros :eek:

25" is already probably too small, so 24" 4k no thanks!
 
Here's a dumb question.

Do the HDMI inputs do the full 1440p from a PC? And Do they scale if there were a console hooked up?
I have to ask because I had a 1440p monitor with HDMI that only did 1080p through it. Ugh

The 3.5mm jack is an audio out, right?

Thanks!
