Nexus 5 Screen Colour Reproduction

So Tweakers have run their test and have discovered that the N5 has some of the most accurate colour of any phone ever!

I agree after having it for two days. The display is amazing. I thought it was washed out since I was coming from the G2 and note 3. But after my eyes adjusting for the past 2 days it truly is awesome.

I was just comparing Note 3 vs N5 and thought the same thing. Little washed out, but almost refreshing to the eyes that it's not so over saturated.

Coming from a Nexus 4 I really love the screen and there is a noticeable difference between them! It's like it feels very easy on the eyes.

Yes, our poor eyes have been hurt by these over saturated amoled [email protected] for ages, it's time for a change. We need accurate colours on our screen. Apple devices are the best in terms of colour accuracy and it's good see android devices catching up. Actually, HTC One is regarded as having the best overall screen if you read Anandtech's review.

Yea when I compared the screen on the N4 to my N5 I was like:

Like I suspected, contrast is worse than on the N4. To be honest, I'd trade some color accuracy for better contrast and/or better viewing angles. Especially on a mobile device where color accuracy is not critical.

Viewing angles are critical? 99.9% of the time I'm looking at it straight on. I'd rather have accurate color, thanks

Agreed, it's a massive improvement on the Nexus 4. Here's my measurement report using my iDisplay3 colorimeter & Chromapure
'Pre-Cal' = Nexus 4 (stock)
'Post-Cal' = Nexus 5 (stock)
Calibration report
very impressive, and is very similar to the one tested above. I could tweak the green down a bit - and dE2000 number (a standard measure of the error) over 3.0 needs to be tweaked.

The Nexus 4 was one of the poorest displays ever produced last year. Man that was horrible. Staring at the Nexus 5's screen is pretty noticeable difference.

Here's another review of the Nexus 5, look at the color comparison charts. You can add phones to the chart and check out their ratings, color accuracy compared to target colors, etc. I'm definitely going to look at this later tonight.
Also, I was just in the mall and a kiosk had a Nexus 5 on display. Naturally, I immediately gravitated to it and compared it to my Galaxy S4 Active. I set both phones on max brightness, and set my GS4A's screen mode to 'Movie', supposedly the most accurate and least saturated mode. The color accuracy of the Nexus 5 is better than my GS4A by a small but noticeable amount, but the whites seemed (by comparison) slightly more yellow and warmer. Is that what's known as a more natural white? My GS4A's whites tend to be colder and slightly more bluish by comparison.

I'm coming from a Galaxy Nexus which had such a grainy screen that it felt like I was looking at a newspaper almost. Whites were yellow & blacks were purple sometimes. That was a truly hideous screen. The Nexus 5 screen blows my mind in comparison(obviously). People say it's washed out, but I kind of like it when compared to the PLS display on my Note 10.1 which I actually really like as well.

Software can fix color accuracy but it can't fix viewing angles.

The display is decent but I would have actually preferred a shrunken version of the screen on the nexus 7 2013. It has much better contrast and MUCH better view angles. I wouldn't have minded if the nexus 5 was 323 ppi if it had those characteristics. You can't see the pixels on the nexus 7 anyway.

I agree. I wish they had gone with an IPS panel with an A/TW polarizer like the nexus 7 2013 has.
A/TW IPS vs regular IPS

Maybe it's just me but I really can't tell the difference between the screens aside the fact that the nexus 5 has better whites
I have used AMOLEDS and I actually returned to a note 2 cos the 3 was too expensive and I don't like the S4. All the screen talk made me buy a nexus 5 but honestly, I regret it.
I have kitkat features installed on my note 2...compare screens, aside the yellowish tint with amoleds, i really dont know what the fuss is about. Are your eyes that sensitive or mine isn;t just good ?

I'm still waiting for the colour comparison of this YouTuber. www.youtube.com/user/TheAngelofmusic1989
Her videos are incredibly detailed, no joke it goes for an hour. She made some good screen colour comparison for the s4 and HTC one I think.

[COMPARISON] Galaxy Note 4 Vs Galaxy S5

Hey all
I thought it may be an idea to create a thread to compare Samsung's two current flagship devices, the Note 4 and S5. While we usually see these two flagships announced at the same time, this year we have best part of a six month gap. For me the S-Pen is a must, which is why I've stuck with the note series since the original. But how much of a deal breaker is this for others?​
Design
Next we have the exterior, its great to see Samsung finally embrace a metal finish. The note 3 had a metallic looking strip around the edge, while sure it looked good, the feel of it was always a disappointment. The note 4 fixes this by using the real deal around the exterior edge, giving much more of a premium feel. The S5 sticks with the same plastic fantastic approach, but is smaller and easier to handle due to its more rounded design. Although the use of metal gives the note 4 more of a high-end device look and feel, would anybody take the S5 due to its reduced size and weight?​
Display
While we're on the subject of size, it brings us to the display. Both devices use the same SAMOLED technology, just the Note 4's being considerably larger. This is to be expected as they are aimed at different audiences.The Note 4’s 5.7-inch 2,560 x 1,440 pixel display gets you pixel density of 515ppi, compared to the S5's 5.1-inch 1080 x 1920 pixels screen bringing 432ppi. Anything over 350ppi will give a sharp display, and its still in debate if these massive resolutions are of any actual benefit to screens of this size. What would members thoughts be on this be?​
Performace
So the nitty-gritty, which is faster? As we have different versions of both devices, we will stick to the Quad core versions as its the one we will see in the UK. Both use very similar Quad core chipsets, the Snapdragon 801 running at 2.5GHz in the S5 and a Snapdragon 805 at 2.7GHz in the Note 4, both are very snappy processors and will perform well, but its hardly a massive leap when we take the time period that's passed. The real difference is in GPU power, the Note 4 packs an Adreno 420 which is claimed to be around 40% faster than the S5's Adreno 330, of course the Note 4 has a lot more pixels to "push" so how this equates to real world performance is yet to be seen. On the face of it we have two very similar devices in way of performance, it may be down to if you like playing games etc. Looking forward to members thoughts on this:good:
Camera
Both devices come with 16 MP sensors, but we have a big difference, the S5 uses one made by Samsung featuring its ISOCELL technology, while the Note 4 uses a Sony IMX240 sensor. Quite why this has happened is a mystery, but we can only speculate that its down to production, possibly working on the S6's new camera?
While the Note 4's camera may be lagging somewhat behind the S5's due to the use of the more traditional camera technology, both are likely to perform well. One thing the S5 lacks is optical image stabilization, this should give the Note 4 an edge in low-light snaps. On the flip-side, the S5 has hybrid phase detection auto-focus, this is used in DSLR cameras and is quicker than the pure contrast detection auto-focus used in the Note 4.​
Summary
Two high-end smartphones, both with their benefits. Please post why you would pick one over the other. Would the size and price of the Note 4 be a put-off and S5's reduced price but similar performance appeal?
This thread has been permitted by the moderation team, and is intend for sensible discussions comparing these two devices and their features. Any trolling or flaming will be reported to the moderation team and dealt with.​

Are we sure the note 4's camera doesn't have phase detect AF as well?

Contrast (true blacks)

How well do you know your fifty shades of grey? Rate this thread to express how good the LG V20's display contrast is. A higher rating indicates that black is true black, rather than a very dark gray.
Then, drop a comment if you have anything to add!

Definitely not a Note 7, which sets the standard for true blacks. I'll bet this screen is easier on the battery.

I'm going to disagree. The Note7 is a standard for "true black" because it is actually true black. An LED/OLED/AMOLED/etc display accomplishes black by simply shutting off an LED pixel, thus creating a 100% TRUE black. (Also, LED being off is using 0 energy).
LCD's on the other hand require backlighting, thus anytime the screen is on, the entire thing is lit. This is why no LCD will ever accomplish a 100% true black. It's also the reason why LCD's tend to be more of a battery hog because all pixels, even black ones, require lighting which requires energy.
To see the difference, put an AMOLED and LCD screen phone beside each other in a dark room and do a google image search for 000000, click one of the results and view it full screen. The AMOLED phone will appear to be off and the LCD phone will still be giving off light.

DING DING DING We have a winner!!!!

Note 4 Note 7 no difference for this discussion same AMOLED panel.
the LGv20 has a nice screen. very nice screen in fact (I now have one) it is not REMOTELY as good as my note 4 screen.
way way way to high a color temp on the panel. its damned near blue. not remotely white. when I use low warming it helps a little but not much. you get used to it but you really really notice in large areas of white.
the blacks are ok but again. horrid if you are used to an oled panel. I hope LG puts an oled panel in the V30 since I know they have the tech (their oled televisions are drop dead sexy alas way way outside of anything remotely in my budget)
what helps is that it has the 1440p panel. this really is the ideal resolution for a 5.5 to 6 inch panel where 1080p is just lacking noticeably. you adjust to the high temperature you don't adjust to low resolution.
sadly so far the camera is crap at night. grrr. was hoping for better. have not really tested in in daytime yet though I expect it will be fine.

So turn down the blue. Nougat lets you.

Hmm.. Coming from a note 7... The 7 still has a better screen.. But increase brightness to 60 and up and it looks really great. Can't complain.

Yeah the blacks cant compare to my note 4 but at least the viewing angle is good enough. Dont notice any colour shift at any reasonable angle.

There's already a thread all about it

It's not much of a thread tbh. I've just read it.

Amoled vs LCD. Note 4 vs V20. You win some you lose some. Having come from Amoled screens (Nexus 6, Note 4, etc) you get spoiled by blacks. However, the colors on the V20 are fantastic. I am a weekend pro photographer and can tell you I feel the V20 is way more natural than the over saturated colors of an Amoled screen. Also viewing angles on the V20 maintain colors while the Note 4 does not.
But back to black levels. This is good for an LCD screen and turning off the top display improves it a lot. The black level is good but it is a dark grey. But when you watch Netflix etc in the dark it is not bad at all. Not Amoled good but definitely not bad.

OK so having done some more watching with the lights totally off, I can say this is a disaster in terms of black levels. I watched 10 minutes of Lord Of The Rings and pretty much stopped.

Default screen resolution

Default setting - FHD.
I changed that to max setting.
Why Samsung decided not to use full screen potential in default settings? Can I expect bigger battery drain?

Yes, it will actually drain more. A good way to know how much you can save being on fhd. Set to max, then go to battery settings and choose any of the other two battery saver mode, next to each"setting" it should show how much time you save if those are toner off. It should show screen resolution, Bluetooth, background data, brightness, and more.
I use that only as a reference to see how much juice I can size based on the settings I have turned on.

Thanks.
Just did some comparison of different saving modes changing screen resolution and in my case FHD saves 7 minutes of battery time compared to WQHD.
So it doesn't make sense using lower resolution. It saves some battery but not that much to sacrifice the main part of the phone (the gorgeous screen).

Well when you factor in screen brightness, that 7 minutes can jump to 45 minutes easily depending on if you're going outside and such. In my Note 8i used to run fhd with a 445dpi. Smooth and crisp and looked like wqhd as much as possible.

I've never seen a noticeable difference on my Note 8. Ran it for a week on mid level resolution, saw no difference in battery life so I turned it back up to the highest resolution. Each to their own, but I don't think the difference is enough either way. Run the one you are most comfortable looking at for icon and text size.

Anyone know why Samsung lowered the dpi compared to the n8?

I'm obviously getting senile in my old age. Was supposed to say PPI.
N9 is 516 , n8 is 521.
Was thinking they'd be increasing it for VR sakes?

Note8 screen size 6,3 inch, note9 - 6,4 inch.
A bit bigger display, same resolution like old 1440p makes this insignificant difference

It's done to prevent battery drain. Increasing it to full resolution won't make any noticeable difference in image quality. As far as battery drain it's really hard to say. The display will always be displaying the full 2960x1440. It really a matter of what uses more power: 1. Having the GPU render all the possible pixels or 2. Have the GPU render fewer pixels but have to upscale the image to the full 2960x1440. I'd be surprised if the difference was really that big. Although to squeeze as much battery life out as I could I'd probably set it to FHD just to squeeze out as much as I can. The full resolution is a waste anyways.

Must be new here cause samsung has been doing this since the galaxy s8. It suppost to save battery but really ot has been show almost no different what so ever. The ui and games are rendered at 1080+ i feel a little smoother if u look hard and the phone doesnt get has hot.

Display brightness to LOW!!

Hello,
I hope someone can help me.
I'm from germany and I bought a new note 9.
I own a 3 year old Huawei Mate 9 and the Mate 9 has a much brighter display as the new note 9 !!!!
I have ordered more note 9 and it's the same for everyone.
Energy saving is OFF... accu is set to Maximum Performance.
Why is that note9 darker than the three year old huawei ???
When I light up the note9 with a bright flashlight, the display becomes a little brighter again. But not brighter than the Mate 9.
can someone help me please?? (

Turn off adaptive brightness

weren't i clear?

check Screen Mode in displays settings. if it is set to basic then it will be a yellowish or dim screen. set it to "Adaptive display".

Mate 9 use ips lcd right? So the display technology not the same. IPS need LED to backlight the screen hence its look brighter when on max brightness because it lit the whole screen. Note 9 using Amoled panel, every pixel capable of producing their own light. So the brightness intensity not the same. Plus i would not recommend using max brightness, it'll make screen burn in much faster on amoled panel.

This, you cannot compare LCD with OLED like that, OLED is superior for a number of reasons but peak brightness is not one of them.

Displaymate test
Samsung managed to get the Note 9's full-screen peak display brightness to 710 nits,

I can tell you the Note 8 has a slightly brighter/whiter display than my Note 9. The Note 7 the same (I still have my Note 7). Side by side, same settings, the Note 9 display is not as bright or white as either of those two phones. It's not a huge deal, barely noticeable really, but side by side you can definitely tell the N9 is not quite as bright or white. And before anyone asks or suggests, of course the settings on all 3 were the same.
