Anyone still going to purchase P2815Q (dell $700 4k) monitor?

How so? I have tried 4K @ 30Hz on a Dell and Asus LCD and it's not usable. Try moving the mouse, the cursor doesn't even track normally. Like I said a simple test of whether or not you can stand to use 30Hz is to try it on your current LCD now. If it doesn't bother you then great go for it, no one is stopping you. But be aware of the limitations before you spend your money on an inferior product.

Cheers mate.

That's a config issue on your setup. I see nothing but clear smooth motion on mine, and that's with either the 39" or 50" Seiki being pushed by a $79 Radeon 7750 at work or $2100 worth of GTX Titans at home.

I'm not recommending it for gaming, NOT AT ALL. But it's just fine for normal desktop use with Office-type applications.

Sorry but by the standards of this forum 30hz is just completely terrible, especially if you have a 60hz monitor right next to it. Maybe it doesn't bother you, or you get used to it if you use nothing but 30hz Seiki TVs, but that doesn't make it acceptable. You're literally the only person I've ever seen describe 30hz as "clear smooth motion". There is, in fact, nothing clear about it at all!

Maybe it's fine for you, but if you take a look at any of the monitor threads in this forum, the things that people complain about, the AVERAGE user on [H] would be totally disgusted with 30hz, there is no real question about it.
 
Sancus is right...the thing you see complained about the most around these parts is slow refresh rates. If you going to get a 30hz one, you might as well just get a TV.
 
I am writing this looking to my 39" Seiki 4K. I used to have a LG 30" 1600p monitor, and I haven't missed it a second since I switched to Seiki last July.

My son is still using the old 30-incher, and while it is a great monitor, even he thinks this Seiki is much better.
 
Use coupon code $3SXSG419DDB2P to save $100. Can this monitor be overclocked from 30hz to 120hz? Or at least to 60hz?
 
I'll let you guys know whats up when I get it. It shipped tonight!

I ended up getting it for $600 + the dell gift card thing. It's not floating around for cheaper than that right?
 
4K monitors can't be overclocked in the same sense as the 2560x1600/1440 panels. To achieve 60HZ @ 3840x2160 you are actually tiling 2 display outputs at 1920x2160 to act as a single display (aka MST). In essence you have a tiled display similar to using 2 physical monitors, but the GPU driver and the DisplayPort hub are obfuscating it as one single display to the OS. The DisplayPort SST bandwidth is maxed out when running 3840x2160@30Hz.

I think we all realize that but the fact that it has MST capabilities built inside the monitor already still makes me wonder if it's truly capped at 30hz.

Also I'm more interested in trying to get 120hz @ 1080p anyways.

DP 1.2 is do support 3840x2160@60Hz in SST mode, but current LCD Tcon's do not. That's why current 4K@60 Hz monitors need to use two tcons and use MST mode.

New generation of Tcons are expected any day now..

I know under linux doing this would be no problem. I could drive my T221 which was tiled (two dual link DVI) to 60Hz when its normal refresh was 48hz (although the panel dropped frames >48 Hz so it wasn't all that helpfull). Not to mention it doesn't sound like this display would be using MST other than for multi-monitor anyway.
 
I read the manual and it is 30HZ.

Honestly I am not yet convinced it is only 30Hz. Not until it is released by dell and confirmed. I just don't see them putting DP on it and it only being 30Hz. I think the guy forbes talked to simply misinformed incorrect. I think there would be just too much outcry from users who did not realize it was 30Hz who bought it from dell and were super pissed after.

I may be wrong but that is just my opinion.
 
Hell no...If I wanted a 30hz 4k display i would pick up a used 39" seiki for $350....Total fail dell, total fail.
 
Maybe it can support 60Hz. Hidden away in a note is the below:

In order to display the 3840 x 2160 native resolution, please ensure the graphic card and its drivers used on the PC/Laptop is capable of supporting resolutions up to 3840 x 2160 at 60Hz via DisplayPort connectivity.
 
Mine should be here tomorrow or tuesday. I saw that 60hz thing too, my guess is it's just a copy/paste glitch from their other 60hz 4k monitors.. but either way i'll call and bitch and say it mentioned 60hz via DP maybe get some more money off it :D
 
So I got the monitor today. it's of course locked at 30hz from what I can tell.

1080p goes up to 120hz but even at 60 or 120 it looks really bad.. the mouse is all laggy almost feels like it's frame skipping. Is this a side effect of running a monitor not at its native reso or what?

Congrats! Some questions for you if you don't mind answering:

What video card are you using?
The mouse is laggy on the 4k desktop setting?
Does the TN panel look like a higher quality panel than the cheaper TN panels?
Have you tried to watch 1080p movies or 4k movies any stuttering on the 4k setting?
Are you planning to post pics?

Thanks!
 
The fact that these monitors are being sold running at 30Hz tells me that manufacturers don't consider PC gaming in their product plans. I realize PC gaming must be such a small piece of their market and hence not worth considering, but it would be nice to see a manufacturer put focus on gaming, but I doubt the numbers add up to make a profit.

I'm using 2 680's in SLI

So it's definitely frame skipping @ 1080p 120hz. I tried playing some games and there was tearing everywhere. No tearing at 60hz.

The mouse feels a bit laggy, yea. If you set your monitor to 30hz you'll see what it's like. There's no input lag though. I get used to it fairly fast, then i switch to my other PC and it's instantly noticeable what I was missing.

At 4k it looks beautiful, I watched some 4k videos and there were no issues. The viewing angles are really great for TN, I see very little difference in viewing angles between this and my IPS panel. Color accuracy out of the box looks really good for a TN panel but it's not going to compete with something like the U3011/U3014 if that's what you are looking for. It's definitely a higher quality TN panel.

At 1080p it looks awful. I'm not sure if this is normal for all 4k displays or just the monitor (or user error) but the colors are very washed out. Then we have the input lag, it almost felt like a full second delay between firing my gun and seeing it on screen @ 1080p in battlefield 4. I'm not sure what the issue is here but it's quite terrible.

I really wanted the 4k for desktop work and 1080p for gaming, I was hoping it would do 1080p 120hz so I'm incredibly disappointed when even at 60hz it's still a pretty terrible experience.

What do you want to see pics of?

Anyways I'm going to play around with it some more, at least for a week then see if it's worth keeping or not. With 3 other 4k displays coming out (samsung, lenovo, asus) I'm not sure if I'll be keeping this. I did only pay $600 ($570 after gift card actually) so that's something to consider.

I need the screen real estate for work but I also like to game, if this is incapable of both I can't see myself keeping it, especially if there's 60hz ones on the horizon which will most likely do a better job at both.

Oh and you can turn on DP 1.2 and MST via the menu so I'm still shocked this thing isn't capable of doing 60hz.

MST alone isn't what enables 60hz operation, it's the complex hardware setup that involves a MST hub, two tcons both feeding the display, etc. It would be more expensive to include that hardware setup. Including DP MST for just, like, display chaining and stuff is much simpler and cheaper, so that's not terribly surprising. This display obviously just has a regular single tcon and hardware that's capable of DP like a normal, standard monitor.

Does seem like a pretty silly product for Dell to produce, though, when monitors that are only slightly more expensive are allegedly using the 60hz setup.

It's pretty sad that things are so messed up in non-native operation.... that sounds flat-out like a bug or really bad/broken scaler. You can't expect 120hz, but there is absolutely no reason that a monitor like this should operate poorly in 1080p@60hz.
 
Sorry my camera is pretty crappy but hopefully you can see what I mean. The washed out effect is even worse in person than what my camera can pick up.

If it looks worse in person then there really is a problem there. I'm no expert but I trust my eyes.
 
My UP2414Q looked washed out if the display did the scaling. When I changed it to GPU scaling in the NVIDIA Control Panel, the colors and gamma were normal.
 
Thanks for the tip, GPU scaling solved that issue. Does the UP2414Q feel laggy when running it at 1080p? The mouse seems less fluid than 30hz @ 4k

Except when I turn on GPU scaling I'm limited to 30hz at 1080p, lol.

I no longer have the display to do any testing, but I remember that when I turned off DisplayPort 1.2 it would do 1080p at 60Hz.
 
I think GPU scaling scales to the native refresh rate of the monitor, and since this is a 30hz monitor it makes sense it's capped at 30hz. Quite a shame. So either 1080p @ 30hz with correct colors or 1080p @ 60hz with washed out colors.. unless there's a way to force GPU scaling @ 60hz.

Try changing the desktop resolution to 1080p at 60Hz before starting the game.
 
It's not even an option to change it to 60hz when GPU scaling is enabled. Just 30hz, and the "hide unsupported refresh rate" box is greyed out. If you create a custom resolution in nvidia it just disappears. I think it's locked to 30 with GPU scaling enabled.

Sorry, I'm not sure how to fix it. The washed out image is one of the reasons I returned my display. I planned to use it to watch movies, and I realized that any device hooked up to HDMI looked washed out. The picture from my Roku looked horrible. I couldn't find any way to fix it. Your display may have the same scaler issue.
 
Nah it's all good, thanks for the help. I don't think there's any way around it. I'm enjoying the 4k resolution even at 30hz but with all these other nagging issues I think I'm going to be returning it as well. I'm not really sure if all the technology has aligned yet to make 4k viable on day to day use. How was your MST experience? I've heard those aren't perfect either as either halve can get out of sync with each other, especially in games.

I may go for the 2560x1600 Yamakasi Sparta off eBay.

MST certainly isn't perfect or as straightforward as a normal monitor, but in 6 months of usage I've never seen desyncing between the halves of the screen on Nvidia drivers. As long as you leave things at 4k@60hz, it works as expected about 99% of the time, I would say.

I didn't have any MST issues, but I only used it for a few hours before returning it. I read about some of the problems others have had. Maybe those are sorted out in the current drivers.
