Full HD on Phones? - General Questions and Answers

Hi anybody
Some new phones come with a full hd ~5" display. My 42" television has also the same resolution
What are the benefit from full hd to xlarge (960dp x 720dp) ?
Cheers, Marc

I'd guess the quality of the image you're getting lol

It's all about the distance from the screen to your eyes.
Smaller the pixel, sharper the image.

As isajoo said, it makes pictures more crisp. Also a 5inch phone held 50cm away will look as big as a 42inch TV which is sitting across the room.
TF101 KatKiss. SGS2 Stock.

Totally Agree

Pretty much the quality of the picture and how close to real it seems.

720p on my 4.5" Moto G looks fantastic, so it all depends on your screen size. I bet 720 would look good on a 5" screen also.

[Q] ..Just got the phone. TEXT is so blurry??

Just got my phone. The txt on the apps and main screens and just about all txt looks very blurry. Pics and such are perfect.
Is this something others are seeing? didn't see anybody mention it elsewhere.
Thanks!
Or is it that it's just not as clear as iphone4 screen?
it's really annoying to look at.
Might be a good time to schedule an appointment with your local optometrist.
My screen with text looks great.
haha. every other screen in my life is good.
Maybe I have a bad one. The app icons all look fuzzy too.
That'll be the Pentile matrix, doesn't bother most people.
Unless you have it really bad, then it might be a bad one.
Pentile RGBG matrix... effective resolution is lower than RGB. Comparing it to an iPhone 4 screen with even higher RGB resolution makes it look worse... so I suggest switching to a phone that has an RGB LCD like the MT4G or something if you don't want to deal with the pixelation. Also, the screen being 4" doesn't help... compared to a condensed 3.5" iPhone display.

That's also why I thought 4"+ was too big for 800x480 (S-)AMOLED. I was actually surprised for Samsung keeping that resolution.
Still, at such resolutions, I value vibrant colors more than higher resolution like on the iPhone 4.
Thanks for the info. It seems what's getting me is that images and apps aren't all made for the high res screen. So some look horrible, others don't.
SO I guess the lack of a standard, like iphone, makes not all apps equal.
hmmmmm
The only thing keeping me from getting this phone is the pentile matrix SAMOLED screen
Pretty much everything will be OK for the screen, 800x480 has been in common use for over a year.
You may have a duff one like me. The text on my Galaxy S is very well defined but slightly blurry on my Nexus S with a dodgy screen. Does your screen look a little greeny / yellow when viewed from an angle?
Unless its really bad blurry, its most likely just the pentile sub pixel layout all Samsung amoled screens have, which causes text to look just ever so slightly fuzzy compared to traditional lcd screens with full 3 pixels. It doesn't bother most people, and It's just a trade off we make for having the nice colors from amoled screens for the time being.
Doesn't bother me one bit. But the larger the screen gets at the same resolution, the more noticeable it gets. Next to my nexus one I can definitely notice it more on the 4 inch than the 3.7inch screen.
I have also noticed this "blurry" text, especially small text against a white background, which is almost unreadable. From an angle, the screen also does appear a bit yellowish. This is my first time with a "Galaxy S" phone, so I may just not be used to it... think i have a defective screen? i've been using a Motorola Droid 1 for the past year, fyi...

No I think your screen is just fine. The amoled pentile is particularly blurry compared to the Droid screen which has text that looks razor sharp. So you're just coming from the device that shows this issue most prominently, that's all.
Certainly my Galaxy S with the exact same panel is perfectly readable from many angles.
My Nexus S text is blurry and the screen is yellowish when tilting.

buy the asian/russian version when it comes out. because it will be SLCD.
you will get what you want.
i like the Super Amoled over the SLCD . i like Ratina over Super Amoled. but to each has his own .
So to you SAMOLED > SLCD, but Retina > SAMOLED. You do know that Retina = LCD right?

ofcourse, you understood me wrong. i said the name" retina " because of the pixel density is higher than normal LCDs or SLCDs. but yeah ofcourse i know lol.
Screen Door Effect... WHY GOOGLE/Sammy???
ok, just had a chance to look at the Nexus S... and WTF??? The screen is so pixelated. The screen door effect is horrible. I thought I took a step back in time for a second. The pixelation is soo bad I would never think twice about buying this phone. Why oh why don't these phone makers give the people what they want.
So, Apple comes out with the new retina display, and while it is way too small, it's soo very very very clear. Google's response? This? Come on... WHY? Aren't we suppose to be moving forward? Ok, so it's brighter and uses less power and has a higher refresh rate... WHATS THE POINT IF YOU CANT SEE ANYTHING???? THERE IS NO POINT.
I don't mean to be harsh... I'm not a Nexus hater... I just wish Google would have done a better job for their flagship phone.
Never been happier with my EVO on Cyanogen...

Get it in another country. In many countries it will come with Super Clear LCD, found on the S8530 Wave II. Super Clear LCD is said to have the advantages of Super AMOLED (sunlight visibility, viewing angle), but wheter that's true or not, it's a really nice display. Look it up on the internet, although I have to warn you, you'll lots of people complaining about the screen because the S8500 Wave I had Super AMOLED.

[Q] Owners respond to reviews

How would you owners reply to this engadget (UK) review
http://www.engadget.com/2011/04/18/asus-eee-pad-transformer-uk-edition-review/
The downpoints they point out are
Broken camera software
Highly reflective glass
Honeycomb still has issues to iron out
Also looks like its bigger than the ipad2 is this a issue?
Thanks, considering getting one but to replace my netbook so not 100% sure, plus it isn't out in the UK until June so haven't seen in the flesh.

The difference in size is negligible. Considering the tablet alone (it wouldn't be fair to include the dock, since the iPad lacks one) it is only 4mm (~2/16ths of an inch) thicker, 30mm (1.2 inches) wider, but 10mm (0.4 inches) less tall.
Also remember that the iPad 2 not only has a smaller 9.7-inch screen, but it also has a 4:3 aspect ratio. If you're going to watch movies, chances are they'll be 16:9 aspect. The Transformer's 10.1-inch 16:10 aspect ratio screen will hence be much closer to the correct ratio, and as a result will need much less letterboxing than the iPad's will.
For a 16:9 movie, the comparison is as follows:
* Transformer -- 8.6 x 5.4 inch display, of which 8.6 x 4.8 inches are used for the movie, the remainder is letterboxed.
* iPad 2 -- 7.8 x 5.8 inch display, of which 7.8 x 4.4 inches are used for the movie, the remainder is letterboxed.
That's 20% more LCD surface area used to view the movie on the Transformer than on the iPad 2. To put that in a way people are more likely to understand, that's ever so slightly more than the difference between a 32-inch HDTV and a 35-inch HDTV.
True what about weight?

You also forgot that at the resolution of the transformer (1280x800) 720p video doesn't get scaled down since it fits fully on the screen unlike the (1024x768) iPad 2.

The Transformer tablet is only 12% heavier than the iPad 2, despite the larger screen and extra features. It's actually 1% *lighter* than the first-gen iPad, and I don't remember anybody loudly complaining about the iPad's weight at the time, so unless the world is suddenly populated by weaklings, I'm sure we'll all be fine. ;-)
Incidentally, the Transformer is also 1/2mm less thick than the first-gen iPad, only 28mm wider, and 15mm less tall. That makes the Transformer around 1% smaller by volume, as well as 1% lighter.
In other words, indistinguishable, but a whole heck of a lot more powerful...

Very good point which I forgot to mention. And the higher pixel density should also make the Transformer slightly less tiring on the eyes.

720p Displays - 'Cool Factor' or a practical improvement?

I’m going to be buying a new phone soon. I’ve been eyeing up the Galaxy S II but I thought I might as well wait and see what is announced this month. One thing that all top end rumoured phones have in common is a 720p display. I have to admit this alone has tempted me to wait. But then I got to thinking, aside from the ‘cool’ factor. What benefit in the real world will a 720p display bring us?
The two main advantages that I can see are improved PPI and the obvious advantage when playing 720p videos. But a higher PPI means more processing power, which in turn means lower battery life. Also from an admittedly purely lazy point of view it means having to zoom in further to be able to read text.
A 720p display will now mean that 480p videos on youtube and the like will be upscaled and won’t look as good. ‘Just choose the 720p option’ you say. Fine, so long as you’re on wifi. Until 4G hits and is widespread (which in the UK is going to take a while) it will mean longer waits and buffer issues.
Yes I’m nit picking but I’d genuinely like to hear your thoughts on the pros and cons of a 720p display. I know there will be many more I’ve missed.
i see it from 2 sides....
720p = really nice picture quality
720p bad for some apps/games, which might no longer run properly, unless fixed, or some how the hardware can auto adjust the resolution to stretch it to fit.
720p can be a bit of a pain, if some Apps/Games developer decide to use too small of a touch area, due the larger dot-pix available in the 720p area
that also means DVD quality or lower quality videos played on the 720p will look like blurry or smeared, that can be fixed with software/hardware correction, like games.
^^ All that.
Plus, I don't really see the need for a 720 screen that's around the 4" size. Do you really need pixels that small? They'll be smaller than photons if we carry on like this and then it'll be reality that'll have to catch up with our tech
Personally, I wouldn't hold back for purely that one feature, but who knows what else is round the corner. Get a phone and let it be the best for a few months and then slowly drop down the list. As everyone always says, there's always something better coming, and if you waited then you'd never get anything.
Incidentally, I do have the SGS2, and it is REALLY nice
well definitely 1080p will be around the corner as we already stepped into the 720p kingdom
so 1080p on a 4" display would not be a long wait, but it will really make you think, what's the point of cramming so much in such a little screen
i can see 1080p to be a normal thin on a 10" tablet, but on a phone... that's a bit much
i do hope they don't go beyond 720p on any screen smaller than 5"
imagine running Windows Vista/7 on 15" wide LCD at 1080 (there are many laptops that are actually like that) it's soooooo eye strain-ful, it literally kills the eyes
i always down set the resolution back to something more readable to not strain my eyes

Do you need your reading glasses as well, so you can find your pipe and slippers?
i don't wear glasses, and i intent to keep it that way, reason why i prefer an easy reading, on 480 vs 720
on 720 i'll have to probably the the font size twice as big, to make it easily legible when you are in the car, bus/subway, or walking
no i don't get dizzy reading while doing any of the above
many people can't read if they are in a moving vehicle
probably due the same relevant issue about having to scan the text in a small device and straining your vision, while trying to keep an eye on the road and not crashing

I agree with you, therebisbreally no reason to go above 720p resolution on small smartphone devices. I myself notice my eyes begin to hurt after more than thirty minutes or so of heavy reading on my Sensation. Now I know my Sensation does not have 720p but I am just saying the size of the screen and the text on that screen is no doubt a strain on the human eye after extended reading done on the device. 1080p is definitely so,ethimg that should just make it to the larger tablets and not smartphones.
Oh and yes actually paying attention to the road while you are driving is a highly recommended activity lol.

This is just plain wrong, low resolution video will look just as good on 720p displays.

Maybe i miss-understood your question, but i am using the Galaxy SII
I never had any screen / resolution issues
Well,first off,let's not forget that Android supports changing the DPI in build.prop(I think-haven't bothered in a while).I don't think manufacturers will leave 220-240 dpi of the current devices on 720p devices,but they would rather pump it up,so that everything stays the same size,but is just crisper.That's just my thought though.
On another note,lower resolution videos won't look worse at all.Resolution in that aspect is irrelevant.The same way that you can play a 720p video on a 480p screen without problems,you can do the opposite just as well.Unless some manufacturer decides to f*ck it up with upscaling tricks and stuff that will defo make the image blurry and ugly.
The only really valid argument on the topic,in my opinion,is the possible lack of processing power,especially when it comes to GPUs.We even saw the Mali MP-400,the most powerful GPU on a PHONE (DON'T SAY ABOUT THE A5 IN THE iPAD!!!!) to date,struggle to keep up in the case of the Galaxy Note's resolution.If the next gen of SoCs doesn't improve quite a lot in that aspect,we'll see some performance drops for sure.Not to mention the worst thing,the losses of battery life in case that extra power is met.Not that I mind about battery life as long as it makes it through the day,but many many people do.
Do any of you guys know the p in 720p stands for?
It has nothing to do with resolution, which is what you are all trying to talk about.

progressive, opposed to the i of interlaced.
Technically 720i use half the vertical pixels for each frame.

[Q] Xoom picture quality

Hi,
I am very close to buy a Xoom wifi but I have concerns about the picture quality of this tablet compared to main competitors. On youtube videos the picture sometime looks washed and not so vibrant like on others.
Does Xoom have IPS display? Does xoom have noticeable viewing angle limitations in portrait/landscape directions?
Original Xoom does not have IPS display and does have some limited viewing angles. Most of us are fine with the Xoom screen, as movies are more natural and don't burn out your eyes while viewing. If you want to share the screen, why not hook up HDMI to a TV or monitor...you'll get a great picture that way. Photos could be more saturated, but I personally like the more naturalistic colors and the camera is really pretty good. Plus these's image editing software in gallery under ICS so you don't even have to use a third party app to burn out your eyes, lol.
Also, please note that a lot of articles/reviews featuring the Xoom tend to show it in the worst possible light. Some folks copped an attitude against it early on and refuse to play fair.

[Q] Screen resolution?

Hi!
What do you think about the resolution of 1280 by 800, is that enough/good? I know this is in most tablets out there but should I think of buying tf700 because its fullHD screen.

I was originally worried it was going to be too low but having owned the tablet for a few months now I can say that its fine. Its obviously not going to look as crisp as a FHD screen but the ppi is already much higher than most laptops nowadays (which have 1280*768 on a larger screen).
If you are still concerned I would advise that you try out this tablet or the other transformers in a shop for a good hour, with all types of use.
I would also say that the only time I really notice any pixelisation is on the home screen, and when reading very small text. You probably couldnt really tell the difference between 1280*800 and 1080p when playing games or watching movies. As already stated in an infinity thread on the general section, this tablet will likely perform better than the infinity due to having a very similar CPU and the same GPU yet less pixels to push.
Good luck with you decision.
i think it s all abouth the price/performance ratio.. a FHD res is always better
