Has anyone else noticed the large amount of ghosting the Xoom display has? Its very prevalent to me, especially when a red or black object moves across the screen (red angry bird (especially when zoomed in), red icon on homescreen while scrolling (pew pew), black bars between gallery images, etc).
Its bothering me to the point of returning it (and looks like I'll have to eat the 15%/$90 restocking fee at Amazon). I'm wondering if the Asus Eee Pad Transformer or Samsung Galaxy Tab 8.9/10.1 will have a better response rate. I know they both should have a better viewing angle with their IPS displays.
I have an ISF certificate and don't see any ghosting...
Really? Could it be I have a defective unit. I just find it hard to believe I would be the only one to have/see this.
Listen enable flash, then open this site on your xoom try to go full screen and tell me your findings.

Btw I have ghosting as well, but never noticed it on before. Thanks for the heads up. Ill reply back when I get more info.
I have no ghosting at all on my nexus one, the screen size have a huge effect on ghosting btw, but just an fyi.
2 Days ago I've been playing DoodleJump on the Xoom, and noticed the game running faster (you can test this) ofcourse you'll have to be familiar with the usual pace of it on the phone version of the game.
I've suspected the frame rate per second to be higher on the Xoom than the Nexus one...which could also be factored in, in refresh rate and then added to the whole performance. Which could spark problems like the ghosting we are seeing.(if you ever tried emulating a PXS on a PC you'll know what I mean)
I know that the screen response time could be a major factor but I couldn't get any information regarding the specifics of this screen. (btw you could be holding two Xooms with different screens)
So my guess for now, is the problem is with the refresh rate on the screen or the way the JIT compiler emulates...which could be solved with an update or a software tweak. Take what I said about the software side of this with a grin of salt
wow horrendous ghosting!!!!! (Using the ghosting test above)
Bumping this thread. Just noticed this on my xoom! Is it normal?
Another test : try going to http://tinyurl.com/xoghost and watch the drumsets at the bottom of the page and the guy in the second last row of second page ghost when you scroll the pages up and down.
Sorry... just saw the responses to the thread. For some reason my email notifications were off.
I ended up returning my Xoom to Amazon while still in the 30 day window so I can't do any further testing. One of the primary reasons for returning was due to the screen ghosting (and overall screen quality). I've also got my eye on the Asus transformer with the IPS display, but it keeps getting delayed. I might just wait until fall reign the next wave of tablets come out... maybe something with a tegra 3

I'm also seeing quite a bit of ghosting. Is this typical for xoom users?

It would seem so, It's absloutely terrible using the ghosting test linked. I'm getting a ghost the length of the actual cube trailing on my screen, in full screen. =/
ASUS Transformer doesnt suffer that much with the links you posted.
There are two different panels for xooms, one being AU optronics brand (typically sited as the cheap/crappy display) and the Sharp brand display which is supposed to be better.
I have the AU Optronics display and going to the ghosting URL linked previously I get terrible ghosting.
Can anyone with the sharp display test this and see what they see?
You can determine the display type by typing dmesg into a term emulator.
Sharp panels say: 'lcd_manfid=SHP'
AU panels say: 'lcd_manfid=AUO'
Now since dmesg is the kernal ring buffer you might need to reboot before you see it in your dmesg output.

I'm not surprised by the ghosting on these displays. Every mobile device I've owned has ghosted horribly. Even a lot of monitors around the office do it, but people don't seem to notice or care. I've always used 2ms displays at my home setup because of this. That being said, I paid about twice what other displays of similar size cost. People don't want to see the price of their precious electronics going up without seeing more nice specs on the list. A low response time display won't sell as well as a faster CPU or RAM... If you find a market that is looking at those 2 specs then make them great. Cheap out on the rest.
Actually this ghosting effect is due to the speed at which the pixels can change from one color to another. Some displays have issues with different color transitions.
This is something that doesn't happen on my nexus ones amoled display. And most of my monitors that I have also don't have this issue, at least to the degree of the xoom. It is disappointing to see how cheap the xoom display is.
I bet my droidx doesn't suffer from this either.

Maybe I'm crazy, but I began to notice ghosting on the screen, especially on the desktop after I upgraded to 3.2 Honeycomb.
If anyone can test whether the effect exists in 3.0 and 3.2, I appreciate it.
UK Xoom Wi-Fi only and I get ghosting too!

Yes, there's some ghosting, but so what? What does it actually affect? I haven't found any effect whatsoever.
Doesn't bother me. Just posting my findings.

I know...I wasn't shouting or anything ;^ )
I just think this ghosting thing is not a big deal.
I just got a G2X yesterday and it has backlight arterial flow. It's not obvious looking head on but it doesn't take much of an angle to see light peeking around the edges. I've heard this is a "known issue" but would anyone else return their phone for a replacement? How likely is it that I'll have the same problem with the next one? I've had the vibrant since release and I've gotten used to the contrast and color of the amoled screen but I don't think I'm just being spoiled. For $500 I feel light bleed should not be an issue. Black uniformity? Ehhhh not quite as much but still... Anyone care to comment?

It is very likely you would get another phone with same issue.
LG uses a screen texhnology that has that bleed.

Youre new around these parts aren't ya? Lol
Its a very well know issue. Look around this forum and you'll find countless references to it. It comes down to what is acceptable for you? Some people have returned and exchanged multiple times to correct it. For me, its barely noticeable and only on a black screen in a dark room so it doesn't bother me.
Look around the forum and then judge for yourself if you can live with the problem.
I'll probably try a return and if it happens again, I'll just deal and think about an upgrade later on. Like I said I'm used to the samsung screens so this problem is all new to me. Overall the build of the phone feels sturdier than the vibrant. I also like that web browsing is much smoother.
I can deal with that. I don't want reboots and a over heating phone. The screen problems are minimal on my phone.

Have you done a complete hard reset/restore of the phone? Factory data reset?
It significantly cooled down my phone after doing it. Never had a reboot on the phone afterwards, but prior to that I only had one reboot, so I don't think I had a problem
I had installed a bunch of task killer/ battery saver apps on the phone, and the combo screwed things up software wise.....have not touched any task killers since.
I try that when I get a my new memory card.
Thanks.

If mininmal light bleed is your only problem just keep it. Most likely the replacement will also have it. Even with light bleed the screen looked better than the sensations...

Ok Xoomers does anybody have grey horizontal bleeding on your display?
When the screen is pretty dark the black seems to "bleed grey" horizontally.
I don't know how else to describe it.
I can see it noticeably durring the boot animation, but there are other times it's worse.
It's been there for a while now but I thought it was software related until I noticed it didn't go away no matter what I flashed.
I just filled out the Motorola warranty form and I'll be sending it back. I just wanted to see if anybody else had the same issue.

I don't and have never had this problem. Did you say it just started or has it been like that since the begining?
I first noticed it after I flashed the first tiamat kernel. I thought it might be related for a long time but it seemed like a small price to pay for the added features... and it wasn't really that bad then. Its gotten a bit worse over time.

Do you think it could be related to overclocking the gpu?
Possibly. I don't use any apps to overclock it (like set CPU) but it might be being pushed harder anyway. I haven't set myself back to complete stock yet but I guess I will have to before I send it in. I'll see if it still shows up then.
Sent from my Xoom using Tapatalk
I did still notice it when I went to the 3.2 rooted update. And that was the stock kernal I think.

If the gpu got fried, I would think that the damage might be lasting...that's a big "if" of course.
Well, good luck with the return?repair? and keep us posted. I'd like to know what that is.

Hey mr_wrong i have the exact same issue...how did your return go?
Lol, mine does that, too. I just thought the display sucked. I am 100% stock. I just got this thing in an acceptable state and dread the prospect of getting something worse as a replacement. If this is not normal, I'll try to get it fixed.

I have an invisible shield (Zagg) and that case that Best Buy sells. I noticed the banding issue too. Turns out it was the impression that the case makes on the shield. Confirmed when I removed the shield.
Sounds like you guys issues may be deeper, though

I have been reading reviews on Best Buy and Amazon, and the biggest complaint seems to be the build quality of this tablet. I was wondering what everyone's experience with it is. Does the device feel as flimsy and plasticky as I've been hearing? Thanks for any responses!
Depends on if you get a good one or bad one. Most people with a flimsy-feeling device end up having problems.
As for my experience with build quality, I'm on my 3rd TF300. The first one had a dead pixel and some light bleed but was otherwise perfect, and the second one felt a little flimsy; it ended up having a bad touscreen. So far, number 3 is flawless after a week. *knocks on wood*
Mine seems fine.The plastic is sturdy and I have no complaints. there is a tiny bit of lightbleed in the lower left corner of mine but its so small that I never notice it.

Took back my first one. Had the normal amount of light bleed, but one spot was exceedingly bright compared to the rest of the screen, very irritating. It also needed the case snapped back into place in a few places around the outside edges.
The second one had light bleed, but only visible in very dark rooms. No other problems.

Not sure if I have a bad touchscreen or not but in the browser when pressing links or selecting them it gets them wrong a lot? More so in Chrome so far.
The tablet is laggy and freezes in the browser at times as well? Anyone else had this?

Try a restore? I want one of these, but the thing holding me back is the "hardend" glass. I wonder if it is actually strong and somewhat compares to gorrilla.
Thanks so much for your input guys! After reading your comments, I'm definitely going to get one! Now I can't wait until Wednesday when I get paid!
i honestly cant fault this tab mate and if you root and overclock it its mind numbingly fast all games worksoooo good and browsing is great aswell

I have owned a dozen or more tablets and so far I am enjoying this one very much. Of course plastic is plastic and can't compare to the metal versions, but unless you are using it to play ping pong, it is just fine. The textured back gives it a different feel than most, hides the fingerprints and definately had character. As far as performance, it is very nice. It is the smoothest running tablet I have had next to my Galaxy Tab 10.1. The speed with the Quad Core is noticeable and I have attained Quadrant scores of 5400 compared to my overclocked Galaxy at 3800. Well worth the money.
I'm starting to notice s little butn in around the edges, anyone else notice this? Anyway to fix/ avoid this?

I use the screensaver deal when charging. Havent seen anything on my phone yet. Maybe that will clear your pixels if you try. I treat these screens like i do my plasma tv. Had burn in from keyboard on my S3 and thankfully, nothing to report like that yet with the S5.
