You can't have your display hardware throw its hands in the air and proclaim that it'll drop a few frames because they couldn't be compressed sufficiently. Lossless compression is nice and all, but if you want guaranteed results your algorithm has to be lossy.

Ok my U2415 came in and I followed the calibration settings here by setting the brightness and contrast and rgb to what they calibrated their icc profile to and also activating said icc profile. In the display menu though there's a setting for "Gamma" with options "Mac" or "PC", what do I set this to? I thought the gamma was set by software/the icc profile. I mean I plan on using this monitor mainly with a PC but I also have a MacBook that I might want to plug into the monitor every now and then when it's convenient.

I think the "Mac" just sets gamma according to the Macintosh RGB color space, which to my knowledge, hasn't been an active standard for a long, long time. Just leave it on "PC" since the whole world runs on sRGB anyway.

Malcolm XML posted:also there's bound to be motion issues and poo poo. if even a lil stuck pixel is annoying, imagine a degraded line of text To be fair, isn't DSC supposed to enable crazy poo poo like 8K@60Hz? To notice text artifacting at that resolution you'd need to be sitting 2 feet away from an 80" 8K monitor - and even then you'd only pick up on really nasty stuff like 4:2:2 encoding instead of 4:4:4. DSC is supposed to be way better than that. Honestly, I couldn't see the effects of DSC on the VESA-published test images at all, and I was looking at some of the illustration for worst-case scenarios such as cleartype text. (Go here: http://www.vesa.org/faqs/, scroll to DSC Faq, click the "here" link in the answer regarding test results, fill in registration form, access zip files of images and spreadsheets.) I too would much rather have an affordable cable that can actually deliver all the bits to the display, but DSC really doesn't seem to be all that bad.

I'm running a Radeon 6850 And yeah it's crazy. The picture in picture thing is really cool for my Xbox so I can watch tv while I have more room than before. I have a bunch of finance spreadsheets open for work that I can actually see all of. It's madness. I don't know if I would spend 1200 on the highest end model when oled 1080 tvs are 1399 but for less than 500 this feels like an amazing upgrade. Especially when compared to my old apple Cinema Display that I sold for 280 on CL.

Looking to replace 1080p two monitors with a single one for dev work. Budget is around 1000. My rig 7i-2600k Z68 Radeon HD7800 First question, can I run 3440x1440 or 3840x2160 on this or do I need an upgrade? For dev/productivity is ultra wide 3440x1440 prefered over true 4k 3840x2160.? Whats my best bank for buck for around 1000?

Could you post pictures of the backlight bleed you're seeing, assuming that's why you're thinking of seeing if you can replace it. I ended up ordering a refurbished one earlier in the week when they had a 35% off sale and it arrived unexpectedly today. It was missing a backplate but otherwise seemed to be ok, though I could see backlight bleed at the corners so now I'm wondering if I should try to get it replaced too. I've bought a number of Apple refurbished items over the years, and wow is Dell's refurbishment process underwhelming by comparison. The screen was somewhat smudgy/dirty, the monitor barely wrapped and with stand attached, nothing on the display panel itself like the new units get, and of course the missing backplate that should take all of 5 seconds for someone to confirm is present or provide a new one. I'll try to spend Saturday or Sunday putting it through its paces though to figure out why it had been returned.

Mine came expertly packed and smudge free with a backplate. It had padding around the screen and the display was fully covered. The photo looks worse than it does to my eyes.

My new one had barely less backlight bleed than that picture, and all it really impacts on is my ability to play Alien Isolation in a dark room. Anything more and you can't really see it.

Yeah my concern is more that given how it was packaged, if anything could have happened during shipping or whether 90-days will be enough time to find something wrong with it. The backlight bleed doesn't look much or any worse than that though.

The backlight bleed doesn't look much or any worse than that though. Bought the same refurb Dell U3415W. It was well packaged and came without a scratch on it and the backlight bleed is similar to the posted picture. The hardest part is getting use to how huge the monitor is. I can't say if 90 days would be enough time to notice any problems but I'm very happy with the monitor.

Is there a way to disable the led light on a U2415? I've found the menu setting to turn the diode off when the monitor is on but it turns itself back on when I turn my computer off and it's quite annoying. e: also why does my computer keep setting the refresh rate to 59Hz? I mean I know it's not a huge difference but the fact that it won't save my settings and reset back to 59 is super annoying. Boris Galerkin fucked around with this message at 21:07 on Mar 5, 2016 |

No idea on how to turn off the LED, I've not needed to do so on mine since the LED is so dim that it does not bother me at all. And the 59Hz thing is a windows reporting bug, it's actually 59.94 and Windows rounds down every time.

I asked this a while ago, but you people with the U3415W are you using the DP or HDMI2 port? If it's DP, are you having issues with the monitor waking up from sleep when turning the computer on? What are you using for a GPU?

Plus they say that to get the 120Hz, you'll need DisplayPort or Thunderbolt 3 via USB-C. Are there any video cards due out soon that have USB-C outputs?

Cockmaster posted:https://pcmonitors.info/dell/dell-up3017q-4k-uhd-oled-monitor/ 2-3 years, probably. Then again, OLED has been "2-3 years away" for like a decade. There are no current video cards that can push 4k@120Hz, from either a GPU horsepower or a simple transport side. A 980Ti can get close if you're willing to turn a bunch of stuff down, but you'd realistically be looking at SLI'd 980Ti's or better if you wanted to game on it. Now if you just wanted to play some Valve games or whatever...yeah, much easier to do. But you'd still need DP 1.3 or TB (doesn't really need to use USB-C if they don't feel like it) for the bandwidth, and neither are supported by any video card right now that you'd actually want to use (there are some iGPU-driven TB options, and that's about it). The next set of cards dropping in a few months should support DP 1.3, though, so at least that would answer that part of the problem.

Couldn't they just have some RAM and a little flash drive on the monitor, which would simply add up which pixels and subpixels had been lit in its lifetime, at which intensity and and for how long, for every frame, and then calculate the negative of that to display in order to remedy the burn-in? 3840 x 2160 x 3 x 8 would be just under 200 megs for a plentiful 64-bit value for each subpixel...

PC LOAD LETTER posted:Small screen OLED was easy. Its big screen OLED's with high resolution that is hard to do still which is a big part of the reason why the cost so much and took so long to show up despite industry promises they'd be cheap as hell and huge with demos 10+yr ago or so though they started getting mentioned in the late 90's in industry conventions with talk of ~10" screens showing up in 2003. Sure, but this was in response to someone talking about when OLEDs go mainstream they'll only be used in cell phones. They are mainstream, but maybe that's what the person was trying to say. Given that you can buy a (n admittedly very expensive) monitor, or notebook, or some pretty high res tablets with OLEDs, in addition to some of the most popular smartphones on the planet, it's safe to say that OLED is already mainstream. You can buy a 4K OLED TV for under two thousand, and you can find a 1080p model for substantially less when it's on sale. Anyway, I totally agree that we'll see some actually affordable monitors starting sometime next year, especially if Apple switches to OLED screens for the iPhone in 2017, which will make everyone start talking about the tech.

I just got my yearly bonus and it's burning a hole in my pocket so I'm looking to upgrade from a Samsung PX2370.
I'm leaning toward the ASUS ROG Swift PG279Q. Do you guys have any other recommendations at or below that price point? (I considered the Acer XB270HU but I can't seem to find it in stock anywhere at a decent price.) Have any of you had any experience with Newegg's open box items? They have the PG279Q for $599 as an open box item but I have heard bad poo poo about Newegg's customer service as of late. Sans that, I can pick it up at my local MicroCenter for $799.

Either get it from Amazon or Microcenter, both are good about returns due to issues like backlight bleed. You will probably need a new video card too, at least soon because 1440p needs a fairly large amount of VRAM and GTX 670s in SLI only have 2GB. New GPUs are coming out in the next few months so it's probably best to wait for that and buy a GTX 1070 or whatever when it comes out.
