One interesting hang up lies in the video inputs on this monitor. It only has HDMI 2.0, Mini DisplayPort 1.2, and USB Type-C. As posters over at [H] pointed out, the HDMI 2.0 and DP 1.2 connections do not have enough bandwidth to support the panels 3840 x 2160 resolution at 120Hz. Fortunately the refresh rate is not a lie. There is a a way to do it, but users will need to use the USB Type-C connector and it’s DisplayPort Alternate Mode feature to do it. At DisplayPort 1.2, the DisplayPort Alt Mode can give you 5.4 Gbps per lanes and using all four available lanes can hit a total of 21.6 Gbps which would be enough to support 4096x2160@60Hz. However, the DisplayPort 1.3 standard (which this monitor and it’s USB Type-C port seems to support) can give up to 8.1 Gbps for up to 32.4 Gbps of bandwidth (25.92 Gbps after 8b/10b encoding overhead) which should allow the full 3840x2160@120Hz to be used. It is unfortunate that Dell opted to go with this odd port arrangement and not include a direct DP 1.3+ port though!

that is a different monitor. (the monitor isn't 120hz anymore)

So there is no displayport alt mode? I sent mine back today for a refund, so I can't check mad.gif

maybe i'll start with the LG c7.. i know that will look better if i put time in to it. I'm not totally sure about this monitor.

I spend so much time screwing with colors this weekend that when i looked outside the window i started questing if the real world spring colors were their correct colors. smile.gif

I am about to yield. I really don't understand this display and who it is targeted towards since the input lag is too high to comfortably game on(at least for me) and none of the color presets are accurate-- at all The standard preset seems to use the full gamut this monitor covers. And while it is awesome to such a wide color gamut who on earth can use it? It's not calibrated to any standard.. It's just here is the gamut and nothing looks right. Switching over to the Color Space > SRGB mode gets things under control-- except it's horribly off. The gamma seemed to be approaching 3-- a far cry from the 2.2 setting it claims. I tried using both the dell calibration tool and the i1Profiler and neither of them really improved upon the gamma, though they did help with the color accuracy.

Things did improve when I tried using basICCcolor display 5. Things actually look fairly accurate now and the gamma measures well.. but this all depends on how accurate my i1 meter is on this screen... seems iffy.

The other thing to me is that compared to the 3 other lg oleds I own this lacks the "pop" I am accustomed to. I dunno.. confused.

It lacks the pop because its a 60hz display with 120 frames of black strobed in. I don't care what anybody says, when you are looking at 180 frames a sec and 120 of those are BLACK your gonna have muted colors. If we could get this thing going 120hz + 120hz strobe, its colors would pop better, the lag would halve and it would be the ultimate gaming or video review display.

First gen OLEDs from LG were tough to calibrate too.

I hope LG makes an OLED monitor in the future (I assume they aren't the manufacture of this one, since it's RGB). I think LG's OLED manufacturing process is really mature now and that's why Sony decided to use a panel from them with the A1E.

I picked one of these up and have been using it for several days.

My primary monitor has thus far been a 65" LG G6 OLED that I've used since mid/late March of last year. I got it as part of the very first release when stock was only provided to a handful of retailers.

I have not noticed any major uniformity issues with the Dell. There do appear to be two bands that are slightly more red near the sides. Uniformity seems better with the compensation turned off, but I am not sure that holds true if the brightness is adjusted to be equal in both cases. Overall, uniformity seems on par with my G6, which I should caveat by saying I was lucky enough to get one without any significant white or near black uniformity issues. Two previous EF9500s I owned had some catastrophic uniformity problems to the point they were unusable.

I can notice the fan as a high pitch whining sound. It took a while to figure out that the monitor was producing the sound, and I had to read this forum to determine it was a fan.

My significant complaint about the Dell is that I can notice the pixel structure of the display and color fringing at the edges of text. It's mostly noticeable on white backgrounds, but other solid colors have a similar effect. The pixel structure almost looks diamond shaped, but I'm not willing to state that with certainty. It does bear a striking resemblance to quite a few displays I've seen in Samsung mobile devices. Do note that I'm sitting roughly 1 to 2 feet away most of the time.

Has anyone else noticed this about the pixel structure?

well... I don't think the dell tool is that helpful. I think it isn't using the expand color gamut that this monitor uses. But who knows because only "native" (whatever the software thinks that is) is used.



It is getting closer. I don't need it to be "perfect" (but that would be nice if it was smile.gif ), but i can't use it if it is distractingly bad - which it has been.
I think i'm ok with how it looks now, but i'll play around more with calman and this new meter. This meter is certified correct too. So at least i know the reading i'm getting are good. I'd like to think the i1d is good too.. but i have no way to know.

That's... not how it works. It's an emissive display, so if it's strobing at 120hz, the pixels are lighting up 120 times per second, period. The fact that it only takes a 60hz input just means that the pixels light up twice per frame instead of once.

what % scaling are you on?

Is the fan hybrid or does it run even on a 100% black screen? is it consistent or change in pitch? I can't imagine having 3 of those if it spins up/down.

If we could get this thing going 120hz + 120hz strobe, its colors would pop better, the lag would halve and it would be the ultimate gaming or video review display.

120 Hz strobe does not mean 60 color frames and 120 black frames, as that is nonsensical when you think about it... you can't have a color frame followed by two black frames in a row, because you can't have consecutive black frames since they just combine to become a single longer frame. If you're thinking of 1 color frame followed by a black period that's twice as long as the color frame was shown for, that's called 60 Hz with a 33% duty cycle.

120 Hz means 120 image frames are being shown on the screen. If it only takes 60 Hz input, that means it shows each frame twice, so 120 image frames, and 120 black frames. (Frame 1, Black, Frame 1, Black, Frame 2, Black, Frame 2, Black, etc.)

Strobing reduces the overall light output of the display, but it doesn't affect color any more than turning down the brightness would (in fact brightness control on most lower end monitors is accomplished by doing exactly that, strobing the backlight with a lower duty cycle for lower brightness).
