Just ordered my Dell UHD 24 Monitor UP2414Q

Well good news, apparently the issue is not there when using a quality full size DP-DP cable that came with my Eizo. The flicking was happening when I was using the thin Dell included DP to mini-DP cable. Are you guys using that cable? Seems to be quite cheap.

But overall though I do not know if it was the cable, or if that min-DP input is bad. I thought it quite odd for the monitor to have a full size DP and a mini-DP input.

The flickering would happen at about 10% brightness levels and below.

Could you tell me more about this half screen glitch? I haven't had any half-screen issues.

I love using this monitor, once you get use to the clarity and the awesome colors it's hard to go back to anything else lol. Although, the black levels aren't bringing in any records and it has my traditional nemesis; IPS glow.

Finally take to oppertunity and bought this monitor and, its awesome, no more troubles with not working AA, just some small smaa and eveything is razor sharp and alias free in games :)

But I have some problems, sometimes the resolution reverts back to 1920x2160 (one screen? it is eyefinety in theory) Switching on and off the power to the screen seems to help.
Also some games run only in weird resolutions, Tobmraider is stetched, others just just play's in a halfscreen? Some suggestions?
I have GPU scaling on in catalyst settings and set keep full screen ticked on, is this the correct setting? Also set displayport on 1.2 in OSD.

Also another weird thing, the provided DP to MDP cable won't work, screen goes into sleep mode (no signal?). I use another DP to DP cable.

I have two R9 290X's in CF, (and you need them :D)

Ya, I've noticed too some strange behavior that games won't run 4K properly, even if its set in the graphics menu. Really it's a shame that you have to run Eyefinity/Surround on all these new 4K monitors.

Sounds like your DP signal is weak, why its having issues. I also found out that my screen backlight still flickers with the full DP input, so back to Dell this must go. :mad: Does anyone know if Dell does cross-shipping?

Yes they cross-ship.
 
I noticed that the flickering a lot of the time would "act up" on the left hand side of the screen when moving the mouse and/or scrolling light colored web sites. Look's like the flickering might be caused by a defective dynamic contrast circuit at low brightness levels. Turned off dynamic contrast (which was on by default) and haven't seen the issue yet. Anyone want to turn dynamic contrast on, zero bright and use a light colored background web site for a bit and see if it happens?

May keep the monitor after all if its just a low brightness dynamic contrast issue, as generally it's better to keep dynamic contrast off anyway.

The half screen glitch looked exactly like the image I posted earlier in the thread, vertical green, red and white lines with glitches in the image. It didn't matter if dp 1.2 was on or off. It seemed to happen randomly between 3-5 minutes and sometimes up to half an hour. I also tried an hdmi cable and the same thing kept happening.

Since I was still waiting for the replacement to ship, I was playing with it last night and it happened again as usual, but then after a while, the right half of the screen went out completely (seemed like no backlight was functioning on just the right half). I tried to power down but couldn't get it to turn off so I ended up pulling the plug. After plugging it back in, I tried the power button, and now the unit won't power on at all. So much for just the single stuck pixel - I've now got a completely dead unit.

The replacement screen shows as 'in production' and I don't have an eta for delivery. So far I'm not impressed with the quality of this first wave of panels from Dell. If this second unit doesn't function properly, I may not have the patience to go through another round of calling support, wasting time with trying to 'fix' the 'problem' and then waiting around for another to show up.

Anyone else making a 4K, 190ish PPI monitor, preferably in gloss?

Unfortunately, not that I am aware of. I would love this exact monitor in a VA panel. I love the IPS colors, but I think I would trade slightly worse colors to get rid of the IPS glow and gain VA's marvelous contrast and blacks.
 
Switched over to my old VA 24" 1080P 60 Hz screen for comparison after using the UP2414Q for a while and the transition was quite shocking.

Dropping down to 1080P, everything looks completely blocky/jaggy and ugly. Also, even though the UP2414Q has a matte AR film, it doesn't appear to be as bad as this full matte/sparkle on this BenQ VA panel.

I just received my unit. Well packaged, quality stand, beautiful panel. Hooked it up and was playing with the settings and after a few minutes the touch buttons become unresponsive and the right side of the screen goes crazy. Checked the cables and everything is good so I power off and back on again. Same thing happens. Any one else having this issue? Doesn't matter whether or not I have dp 1.2 enabled, changing any other of the display settings doesn't seem to do anything to help. Also, I noticed a single bright/stuck pixel in the center area of the screen. Am I just unlucky or what? :mad:

Mac os X issue? I know with one of my active DP -> DUal link DVI adapters I got a similar effect after a bit of usage even though it worked fine on the exact same macbook running linux...

Hm. That makes me think twice about switching over to 4K for home use, since my work computer will probably be upgraded to 4K sometime in... 2050 or so.
 
Ya, the 4K 24" is just simply gorgeous. I have a 24" 1080p monitor for sale cheap. ;)

I did some testing with OSX (Mavericks), Windows 8.1 x64 and Windows 7 x64, display port and hdmi, intel 5100 iris and gtx 680 - in every combination I could. Even with updated drivers, the same problem persisted, and now the panel is completely dead and won't even power up. This happened last night while I was trying to unstick the stuck pixel it came with. One side went dark, and upon attempting to force restart the panel, the power switch failed to start up the panel. No Dell logo, backlight, anything.

Fortunately, I have another being sent over from Dell, but it looks like shipping is 1-2 weeks out. I really like the pixel density and color reproduction and do not want to go back to searching for a different monitor seeing as no one else offers anything else like it. I think the size, PPI, and potential performance (once I get a panel that is defect free) is just perfect.
 
Ya, besides the IPS glow that all IPS have and the not so stellar blacks that once again, all IPS have, it's pretty much an awesome monitor.
 
Created an account specifically for this thread.

I've had this monitor a while now, I was probably one of the first orders. Bought it over the phone before it was listed online and got it maybe 4 weeks ago. Been using a Mac Pro 1,1 (That's the first gen intel tower after the transition from PowerPC) to drive this bad boy. Using a Apple edition Radeon HD5770, in 10.8.5. Although my setup isn't normal and is running the 64 bit kernel via a Chameleon emulation.

For being such an old card, the system is fairly lag free (30Hz though), running it off of Displayport, but MST doesn't work currently. Enabling Displayport 1.2 causes the monitor to reboot, and if the host computer doesn't have a driver you're stuck. Dell has some crappy programming put using a different source to get past the input menu and factory resetting the monitor let me use Displayport again and unfreeze the monitor.

It is breathtaking however, looking at it, it becomes immediately apparent this is the future. High resolution photography looks better than printed page in my opinion. There is NO 4k content out there, i've edited a little sequence together from free clips to show it off to family etc. But don't get this and expect to find films to play without the monitor making them look terrible.

For those interested in the OS X side of things, the native resolution is super tiny. Something like having a 32 inch display. If you prefer, via switchresx, you can manually add a HiDPI 1080P resolution. Making all the UI Elements easier to see, but sacrificing the big workspace.

Bought this to go with the new Mac Pro, currently waiting on the computer to ship. Apparently Anand already tested the combo and MST doesn't work under OS X but does under Windows. As does crossfire so gaming at native or near native isn't out of the question. Not going to start complaining about Apple only supporting 1 4K monitor until I actually get my unit. That said 30Hz is livable for photo and most video work and the monitor is relatively well calibrated from the factory

I'm seeing some strange behavior in Displayport 1.2 mode on this monitor, but I'm not sure if it's the OS or the monitor. I know it's not the video card because I actually went from a 290X to a Titan to see if that would fix it. (Disclaimer: I am running Server 2012 R2 on this box, and AMD has always fumbled server OS drivers a bit, so I assumed at first that that was the issue.) I have also swapped out cables, from a 15-foot cable to a 10-foot just to be safe. The 290X refused to negotiate DP 1.2 at all.

Basically, I am seeing several things--in Displayport 1.1 mode, the display is perfectly stable. When I move to 1.2, the mode is negotiated properly but both monitors (one of which is an older 1440p model) display sometimes locks up completely after a few hours or days, forcing me to reboot. Other times, DP 1.2 fails to negotiate properly after the monitors come back from timing off, and only half of the screen will show a display. I'm currently running stress tests just to confirm that there's not some other unrelated system issue at hand confusing things. I will also at some point attempt just powering off the monitor when I am away from the computer to confirm that it's not something as simple as monitor sleep detection causing display driver lockups.
 
DP 1.2 at high bandwidth is very weak. You need a high quality short cable.

Mine started flickering again on the left hand side even with dynamic contrast off, so trying to set up a cross-ship replacement now.
 
Had to run the cable over the top of my desk just to get down to 10 feet, there's no way I could go shorter than that. Oh well, hopefully the next generation of video cards will have actually seen testing at DP1.2/UHD/60Hz. Paying the early-adopter penalty, I suppose.
 
DisplayPort - Cable 3 meters for full bandwidth transmission over passive cable.

Technically the specification only allows a 9-foot cable. Pretty silly IMO.

On another note, after talking to about five people in India, I have a replacement on it's way. They said 1-2 business days, but I wonder if these are in stock at the moment. Maybe they hold some in reserve for replacements.

The guy in India said "Have you tried turning it off and back on again". LOL. I was going to tell him "do you know you are talking to Vega", haha JK. He'd be like wtf?

Can you elaborate on this? I'll be needing a 3m cable, so information on cable specifications and requirements would be much appreciated. I well remember the attenuation with thinner VGA cables.

What make/model of display port cable would you recommend?

I talked to more like 6-7 since they accidentally deleted my order (replacement) and I had to call in again to get it going. My replacement request was granted on the 9th and they did not give me an eta. If you get yours in 1-2 business days, I will be very sad... but happy for you!

Yeah, those techs are funny. Like I would be calling in if I hadn't tried every possible thing to get this thing to work correctly. Lowest common denominator I guess.

Sweet man...I'm starting to think I have been the luckiest of all of us....thou the ones that get good luck tend to not post either.
 
You'd be surprised on how hard it is to find good quality, well shielded 28 gauge Displayport cables of more than 6 feet. Hence, why I am using a $700 fiber optic Displayport cable. (Yes my cable cost half as much as the monitor)

For a passive cable, I would not go above 10 feet for a reliable 4K 60 Hz signal.

Vimeo has plenty of 4K video. Here is an example.
 
Couple of questions I tried to find in the thread

Now that these are out, do the owners feel they're worth the price Dell is asking?

Are top of the line graphics cards required for high quality (no AA/AS) gaming?

Do low resolution items look even worse now?
 
Holy crap Dell is fast, from call two days ago, replacement monitor is here and this one is also pixel perfect. Problem one was manufactured Oct, this one is Nov. Time to test if there are any low-brightness back light issues.
 
Sigh, this new one's left side back light also flickers randomly and intermittently at low brightness levels. Confirmed design flaw. Now I have to decide if it's worth keeping and dealing with higher brightness levels to get rid of the flicker or just to return it.
 
Is anyone else getting the flickering?

Vega, could it be an interaction with your lighting?
 
Lighting? The flickering only occurs at less than about 6% brightness, and only on the left hand side of the screen, and is only really noticeable on white or light backgrounds.

For both monitors, of different build months to have the exact same issue, I am 99.9% sure it's a design issue and all monitors will experience this. It is random and intermittent, so most may never even see it unless they do extended low brightness viewing like I do. Probably most people don't use brightness that low either, as I like to surf the web at night in a dim room. Since the monitor is zero PWM, it's most likely the DC inverter reaching its voltage threshold on the low end. They probably missed this during QC testing as it's so random and only under low brightness. For most people it won't be an issue.

Lol you'r funny! $700 for a damn displayport cable. Some people never cease to amaze me.
 
Okay so I just got this monitor today and omfg I love it to death. Sadly though I dont know if this is a bandwidth issue or what but after I enable 1.2DP I got the whole screen flicker issue. I restarted my comp and it went away and i was able to use it perfectly fine. I can use up to two extra monitors but when I plug in my 4th monitor it does the whole flickering thing again and the images on the dell get squished. So I dont know if its just a bandwidth issue or do I just have to daisy chain the monitor off the dell to get all 4 running?

Sorry. I meant the lighting in your house. For instance, I've seen some odd interactions on some CRT monitors with old fluorescent lighting.
 
Um, I hope you guys are smart enough to know why I had to get the fiber optic DP cable. It wasn't because of some sort of silly "quality" thing like these retards that spend thousands on cables because they "think" they can hear/see the difference.

My $700 fiber optic DP cable is required in order to simply pass a signal from my computer 35 feet away. It is technically impossible for a passive cable of any design or quality to do so at 4K 60 Hz and is generally limited to 9-10 feet.

Don't worry Vega.. we know who the retards are here :)
 
Remember, MST is actually 2 monitors. IF you hooking up 4, that's just to much for you poor video card...give the poor little guy a break.

I run 3 computers.....

I very much doubt that some of the posters here have read the DP specifications and limitations. I've emailed the HDMI people about cable specifications and limitations for HDMI 2.0 wrt 4K / UHD but have yet to receive a response. Even the 6ft / 1.8m original limitation of DP 1 is cripplingly short.

Try plugging the cable for the 4th monitor into another video card.
 
After fooling arround a bit with this screen, most things work quite nice. But,..I always have to switch the power on and off though to get a proper 3840x2160 display though. I do this just before the win 8.1 logon, so the desktop icons won't get messed up, otherwise it's always one screen (2160x1920), stretched over.

Also a few games refuse to work properly in 4K:

Tomraider (2013), Deus Ex HR directors cut, Hitman Absolution, Far Cry3 for example. Did someone managed to get this working?
 
So far Ive gotten Wacraft and Dayz working on it. Garrys mod and Counterstrike dont seem to fit well
