Banding on pictures (Wallpaper) - Xoom General

Anyone knows what's the color depth the Xoom displays? Feels like every single wallpaper I use exhibits ugly banding. Does the Xoom only produce 16-bit depth?
Thanks.

[Q] Dell AMOLED vs HTC HD7 LCD?

Everyone has been raving on the DVP's screen, but having had the HD7 while waiting for my DVP to arrive, I've gotta say - I have mixed emotions!
While the colors are substantially better side by side...anyone notice how pixelated the DVP's screen is on text and such? The battery indicator is a good example of what I'm talking about...
I think I might actually prefer the LCD of the HD7 better, despite the lesser black level and color saturation.
Anyone else have any thoughts?
I see what you are talking about... I didn't realize this before you mentioned.
AMOLED in VP is a little bit too much saturated and the HD7 is a wee bit too washed up
A middle ground would have been awesome.
Maybe SLCD or SAMOELD hits that middle ground. My friend is getting the Captivate, will compare this side by side and let you know.
I have a slight blue tint on my whites at certain angles. I dont see a big difference in the two screens, but i expected more from the AMOLED.

I think that was my big let-down. I had (probably overinflated) high expectations of the AMOLED. I didn't see much on the net talking about it, and in fact, most reviews talk about the sharpness of the display, so I was confused if it was just my unit?
I *WAS* able to find a couple of sites that talk about AMOLED having sub-pixels vs a standard LCD/SLCD, and therefore it's not as good for small text or sharpness...
I must say, though, I love the keyboard, and I'm still going to keep the DVP over the HD7 - just a little surprised at the lack of impact from the screen, considering what they've done to build this device (gorilla glass, etc).
I agree with you on the fact that the AMOLED on the dvp has noticeable pixels more than the HD2 that I have. What’s even more sad is that they have the same resolution yet HD2 has a larger screen – Thus I should see more pixels from the HD2, however, this is the opposite.
Why does the DVP have noticeable pixels? Can anyone compare this with the Nexus One and see if they are the same?
Pen-tile matrix effect, probably what you are seeing here. However I cant see what scenario would occur to make me prefer the washed out screen of the HD7, just too darn low quality for me.
Its the nature of the AMOLED screens, my Focus had the same thing. However, overall, I find the screen on the DVP far, far superior to the HD7.
it was my understanding this is more a fault with windows phone 7 as it does not use 16m colours like the display can do.
Personally owning both.. the DVP has a MUCH better screen. Especailly if you change brightness to high.
ive never see an amoled screen before, but coming from the HD2, i was very disappointed.
i guess the hype of amoled screens made me have high expectations which were too high by the time i saw a real amoled screen.
Now that I have a DVP in hand all I can say is the difference is clear, the Dell's AMOLED screen is superior. Maybe some are being swayed by the size but for someone who has had an HD2 for almost 9 months the size is not really a factor and the lack of colour, dim lifeless screen is just no competition for the AMOLED on the Dell.
HD7 Advantages
+Noticeable advantage in color accuracy
+Larger screen offers better spacing on keyboard (portrait)
+Good black levels while inside optimum viewing angles
+/-Brightness is more than adequate (auto brightness is a little conservative though)
+/-Decent viewing angles (No issues during regular use)
HD7 disadvantages
-/+Decent viewing angles (Poor viewing angles make kickstand less useful)
-Slightly less responsive (my opinion)
-Lacks sharpness while viewing pictures (not sure why but they aren't as sharp as the rest of the time with the HD7)
-Color saturation could be better
Venue Pro Advantages
+Excellent contrast with fantastic black levels
+Slightly more responsive touchscreen (my opinion)
+Good brightness
+Excellent color saturation (somewhat oversaturated though)
+Perfect size (my opinion)
+/-Sharpness (pixels aren't noticeable during normal use)
Venue Pro Disadvantages
-/+Sharpness (some users may notice more pixelation)
-Very high color temperature (extremely unusual coming from a calibrated display)
-Can't use the brightness to your advantage without battery drain
-Keyboard felt a little cramped coming from the HD7
I miss the color accuracy of the HD7 but love the size and responsiveness of the Venue Pro. The HD7 gets a bad reputation because of viewing angles but during normal use this is a non-issue and possible advantage with curious onlookers (there will be plenty). It offers better black levels and shadow detail than the iphone 4 but gets hammered for viewing angles. The Venue Pro offers fantastic build quality, an almost perfect size (my opinion) and a more responsive touchscreen (my opinion). It has a very high color temperature but offers superb black levels and color saturation. It is also sleeker than I had anticipated from all the comments saying that it is a beast.
Sorry for the double post
Samsung has bastardized AMOLED with pentile imo. It prolongs display life but the tradeoff in picture quality is too great. There are AMOLED's with normal subpixels, and they look fantastic (Cowon S9, Zune HD, etc).

That's a great point - the ZuneHD I have looks amazing! Still loving my phone, though...
Zoom Sharpness?
I purchased the DVP to have something that will show my pictures a little more accurately than the LCD I have on my HD2 (the slightly extra saturation is better than the washed out look on the HD2) but I now find that there is no sharpness to the images when zooming in.
I have a photo of the lights of Chicago at night and when at the full screen zoom level, it looks ok but zoom in and it is a blurry mess. My HD2 is very sharp when zoomed.
In the Zune software I have tried full size pictures compressed by Zune, pre-compressed images with Zune left on "Original" with no compression and nothing seems to make the images better when zoomed.
Anyone else seeing this problem? This could be a deal breaker for me as far as AMOLED screens go unless it is a WP7 problem. I would love to see how my images look on a Droid device with AMOLED.

I agree with you. Images seem way too pixilated. I mean, I can actually see them which is so sad when I compare it to the HD2. When I am going to do is wait for WP7 to be release on the HD2 by Cotulla and then compare if it the OS or specifically the DVP.
Has anyone seen another amoled screen before in real life? This is my first time I’ve seen an amoled screen. I am not impressed…. At all. Lol but the colors are lovely. Image quality drops, while color saturation grains points
If you read the Cnet phone screen shootout you will see that the HD7 has some pixelation on images of text when zoomed. I have also seen some softness and pixelation on my wifes HD7 when zoomed in. This only really seems to be when viewing images so I would guess it is OS related and not specific to the Venue Pro.
I own a Nexus S and DVP and the dell is getting returned today. Main reason is android is a better fit for me but close second is NS screen is head and shoulders better. No pixelation like I had on dvp.
I think I had a lemon too my dvp was freezing quite a bit.

I find this odd. I had a Focus and an Epic 4G - both have the same screen as the Nexus S - and they had the same pixelation issue as the DVP. It has to do with the AMOLED screen.

Xoom text quality

I have a 1st gen iPad that i was planning on returning and getting an iPad 2 for, but now I've been seriously considering the xoom. One of my main complaints with the ipad is the soft text it has in the browser because of the lack of sub pixel rendering that computers have. I just wanted to know how the text looks cause I really want the wifi xoom now
In my opinion, the text on the xoom is crisp, clear and perfect quality
double post oops
former ipad1 user here.
with the xoom, you can tell the text is crisper from the naked eye alone. 1280 x 800 > 1024 x 768
that being said though, the ipad1 IPS display is of higher quality (better colors, black levels, viewing angles) than the xoom's TFT-LCD display.
however, I did find the xoom's display easier to read under heavy light (outdoors) than the iPad1.
some ipad2's are suffering from some backlight bleeding. I noticed this as well with my iPad1, when using a dark background. as of yet, i have not noticed this issue on the xoom.
I'm not 100% sure on that, but Honeycomb text antialiasing seems to be the same as what you see on a typical Linux desktop - it looks like they're just using FreeType as is? So, in terms of text sharpness, it's slightly worse than Windows ClearType, but much better than OS X / iOS. That said, stock Android font is very well designed, and seems to be tailored for the smoothing algorithm that they use, so legiblity is very good.
Also not that subpixel antialiasing is not as helpful on tablets, because it only gives noticeable improvement when text direction is aligned with subpixel orientation (i.e. subpixels are horizontally arranged as in R-G-B, and so is the text). When you rotate your tablet to put it into portrait mode, subpixel antialiasing would only work vertically, which is much less important than horizontal for text legibility. I don't think Honeycomb uses it, in fact - I don't see the tell-tale color halo around letter edges.
You can find plenty Xoom screenshots by searching for "xoom screenshot" and restricting size to 1280x800 - do that, and judge for yourself.

IPS display is also a TFT-LCD display like every LCD out there. Xoom is not IPS though - it's TN, MVA or PVA or something.
I have the Kindle app on both and I see a noticeable different in text with the Xoom being much better.

[Q] Screen Quality on the Iconia?

How visually appealing is the screen on this beast? I'm talking like contrast ratio, how whites and darks show up, color count, depth, any washed-out effects, pixel appearance, how bright/vibrant the colors appear, (basically I'm not concerned with responsiveness, just what it looks like to the eye.)
Thanks!
Edit: forgot to ask how the ~256k colors appear, instead of having 16 million.
go for a galaxy or transformer so...
Acer screen will not fit your "requirement"
I mean, you move your little fit to a shop, take with your little hands each tablet you can try on this shop, ask with your little mouth if you can try tablet...
look with your little eyes the quality, make your decision yourself...
each people are different, we can't choose for you or make any neutral feedback....
feedback = feeling back... what we feel after try...
so far I don't care so far of the 256k, I care about the responsiveness... and the acer have the same "style" of PSP... can be nice sometimes or boring...

I'm not sure if you're flame baiting or not, this is a rather peculiar question because I think it's very obvious to anyone with common sense then more colors = better picture.
But to answer you sincerely (in case you are genuinely asking), 16m colors is perceptible to me as richer color. I have 20/20 vision and I still don't see or consider what I see on the Iconia to be "washed out" as some would call it.
The only difference I'm seeing between the Galaxy Tab and Iconia are deeper, richer hues and this is generally when it comes to viewing icons, still images, etc. It doesn't translate to video on a whole scale basis. The colors on the Iconia to me are brighter and lighter while the Galaxy Tab colors are darker and richer. The colors on the Galaxy Tab are vibrant and pop while the ones on the Iconia are crisp and clear. In video, the only thing I can really see differently are richer skin tones in movies and more solid colors in cartoons. The black is seemingly darker but not due to the color, more so due to the screen technology. Blacks are black on the Iconia. There is a visible grid in the iconia screen at certain angles and with certain colors but I don't 'see' it unless I look for it. Again, due to the technology.
If you put them side by side I have no doubt that one would pick the Galaxy Tab BASED on screen quality. But sometimes it's 6 of 1, 1/2 dozen of the other; there are obvious and important trade-offs between the 2.
I'd just go look at them if I were you. It's pretty easy, they are both sold by most big electronics stores.

Color Saturation

Does anyone notice how unnaturally saturated the colors are on the Note 10.1?
It's as if the color saturation has been set to "STORE DEMO" mode just for Extra POP like you see on TV Showcases at stores.
I've checked Movie, Normal, and Dynamic modes, all very unnatural looking.
This makes the color of skin tones and other natural objects look extremely exaggerated!!

Contrast (true blacks)

How well do you know your fifty shades of grey? Rate this thread to express how good the Moto X4'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!
Maybe not quite AMOLED but I can't easily tell where a black screen ends and the bezels begin. It's sharp.
best lcd ive seen on a 1080p display. i thought for sure this was amoled. :good:
It's too dark actually. The colors are NOT accurate.
Compare it side by side with an iPhone, Samsung, HTC, etc..
Open and photo and you will notice how DARK the image is when viewed in the X4.
This isn't good when you do a lot of photo editing as it you might adjust your picture and make it too bright.
But I think this the display calibration is intentional. Lenovo wants to fool the consumers into thinking that it has a good contrast.
It does but with the expense of inaccurate colors.
