Is anyone experiencing this. I have massive amounts of overscan. Also, when HDMI is connected a 20 or so pixel high black bar is added to the the top of the bottom task bar. It also noticeably scrunches everything above it on the XOOM. It is unuseable in HDMI. I thought it was the OC Kernel so I went back to a stock kernel and it still doesnt work. I tried two seperate hdmi cables, I am now at a loss. Please help.
I have not used a dock as I don't have one.
The problem is not with the Xoom, but with your TV. Plasma TV's especially like to overscan so that the picture can be panned around to prevent burn in.
On my 60in Pioneer Elite, I had to change a few settings for the signal to display 1-1. I had to change the input to 'PC mode', and then change the 'Orbiter' to a different value (Orbiter is the automatic panning I mentioned).
Good Luck with your TV's settings. Some cheaper LCD's also overscan, which doesn't make sense because LCD's do not have burn in problems like plasma's.

Panny has a menu setting where you can set 1:1 pixel mode, but it has to detect a 1080p signal.
I forgot to mention that I have never had this problem prior to the xoom with many sources. I have a vizio and can't seem to find any overscan settings. there is one setting that seems to be autoadjusting to the xoom but i cant tweak it to work, only look slightly better. As the xoom is being altered that leads me to think the xoom is to blame. since It's getting squished on the XOOM.
EDIT: It now decided to stop working altogether.. other sources, xbox 360, htpc, file server PC, blu-ray player and AVR receiver are all working. I have read about people who couldn't work HDMI over the xoom. This is the first time I have ever had this problem. On the same TV the evo works flawlessly.
mine looks perfect no overscan but sometimes if you let the orentation change it messes up.

I do not believe the issue to be with the Xoom. I've tried HDMI with different displays, different sizes, and the results are not always equal.
For example, on one older Insignia 19" LCD display with built-in HD tuner, I noticed that several pixels are cut off on the bottom and top. On a different LCD, a 24" Acer, the image displays perfectly. On a 40.5" Sony LCD, I had the same issue as with the Insignia, pixels cut off on the top and bottom.
I could try this on several other HD displays I've got around here, but I'll bet the image issue will be hit and miss.

Not to sound like a ****, but it's your TV. Vizio is an economy brand and they know that the vast majority of people will be happy with overscanning or never know about it. Next time buy a better TV. This problem is just a classic example of economics when it comes to TV's.
I bet if you hooked an iPad 2 to this TV - or heck a PC over HDMI - you would have the same problem. Please do not blame/bash the Xoom for this.
- end rant.
I don't think its his TV, I have a panasonic plasma and it overscans. When ln the home screen the google search. Button is cut off a bit on the left. The right is also cut off too. When I plug in my macbook it doesn't do this, so I'm leaning towards a xoom issue...

Do you plug your MacBook in through HDMI or VGA? A lot of TV's have a PC Input over VGA that does not overscan. I have never seen a plasma that does not overscan on HDMI(by default). This is done so the image can be panned around slowly to prevent screen burn in as I mentioned previously.
Just got my HDMI cable and I'm having the same problem with overscan. I do have a cheapie LCD (max res 1024x768) but I don't have this issue with my PS3 or HTPC. I'm betting that's because I've got the HTPC setup with a 1024x768 res and the TV autodetects the PS3 at 720. I believe the Xoom is having this issue because of the 1024x800 resolution.
OK so after all that, I'm convinced this is a TV issue and I can't see any way to change this in the TV options. Is there any app/fix/hack available to get this working?
Edit: Just had a thought... has anyone tried changing the resolution on the Xoom with the LCD Density Changer app? I don't have root but if that works then the list of reasons I should root just got longer.

Vizio makes bad a$$ T.v.'s I have a 60" Samsung and a 47"Vizio and side by side are almost of equal picture quality.
The only problem I have ever had with the Vizio is with component in - pictures went very green - and I really think it was a problem with the actual device(wii).

Are you rooted? If so can you try LCD Density Changer? I have no idea if it'll work but it's the only app I can think off that may change the Xoom's screen resolution.

The black menu bar on the bottom rising is not an error. It is intentional so the picture outputted is a perfect 720p mirror. All the Xooms do this. As for the stretching this does not happen for me. You can see this in action on my own display below if you wish.

Didn't know this thread was still going. I know what you are talking about, the display on the XOOM squeezes to attain 1280x720... but it still was overscanning on the TV so I was talking about two seperate issues.
I have the same issue when testing on two samsung LED screens and a Sony bravia lcd. I read on the moto forums that this is an issue with the device not syncing correctly to certain tvs but the last post was end of march saying we were waiting on the update from motorola.
It sort of sucks because it is a good hunk of the screen cut off

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.
http://www.prad.de/en/monitore/testsoftware/ghosting.html
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

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.

I just think this ghosting thing is not a big deal.
My new G2x is having a little trouble displaying movies zoomed without squishing the aspect ratio. No matter what setting I use in Act 1 or how I adjust the slider in the stock player I get extra skinny everything on my screen, unless I'm zoomed all the way out to anamorphic.
I've been using Act 1 for almost 2 years now, initially purchasing a license for a MT3G, and then using the heck out of it on my dearly departed N1. The cropped zoom setting has worked perfectly for me on both of those phones, but not this new LG.
I emailed Act 1 about this issue and received a swift but disappointing response...
Hi
I really like Act 1, I've used it as my only video player on three different phones now. I'm having a little trouble with it on my latest, an LG G2x.
I don't seem to be able to find an undistorted zoom setting, other than the straight unzoomed setting. I don't know if this screen is non standard or whatever, but I do hope this is something you might address eventually.
Thank you
Spyvie

Spyvie,
Unfortunately, some zoom modes don't always work so great on some phones. It works by making asking Android to render the video larger than the screen dimensions, and some phones simply can't/won't do that. It sounds like the G2x is in that camp.
Hyperaware
So does this mean its a hardware issue that will never be corrected? Or will new drivers and/or ROMs address my problem?
This, along with the light bleed on both top corners of my new phone may be deal breakers for me.
Also, what is the resolution of the G2x display? It's listed as 800x480 everywhere I've seen except this PC Mag review (can't link)
If the resolution is 800x400 I wonder if that's the source of my aspect ration issues...
Bumping from page 3... if that's OK
PC mag article stating 800X400 resolution

This probably won't be the solution to your problem, but have you tried the second button from the left with the standard video player?
Thanks for the reply Steve...
I have tried the little window shade button on the stock player, it just toggles between 3 setting that are also there on the slider.
It would appear that this phone is incapable of cropping video at all. What I'm wondering is if this could be fixed with software or is it a hardware issue. I would think it's a software thing but i dunno.
I've tried the other forums with no luck so here's the problem. I have an Apex LD4088 1080p lcd tv. Cheapie from tiger direct. When i connect Charge i get a pic and audio only for a couple seconds. I move the cable around, still won't work. I took it and the cable to the store and tried it on three others and it worked perfectly. The guy said "it's just something Apex didn't put in this tv". Like what? I've tried just about everything but still nothing. Also on this thing the "advanced" settings are not active on the remote. No 720 to 1080 adjustments. Hopefully you guys at XDA can give some insight on this as the other forums have been unable to.

I've heard of apex but it's more of an off brand like Coby,Hisense,Broksonic,Curtis.
A store like Hhgregg will advertise a great deal on an led or lcd tv and give price but not brand. They hook you into the store and then you see the brand. Although they may not be right for some it might be in the right price for others. If they like the color and want to take the chance go for it. Like I told my father in law who wants a new tv look for the picture and price for yourself. He was all stuck on the name in the start but I know he can't tell the difference between a LED true 240hz 1080p which very few are made. Anyway wrong place for a tv ad lol. Next.

What type of cable are you using and what are the actual resolution of your tv compared to those at the store. I've never really looked into this before but are you using software or just direct connection to the tv?
Heard about apex not working for hdmi out. Not sure why though. It works fine on my panasonics and phillips tvs.
tappin' that....
This tv was $379 a year and a half ago. That's cheap! Great picture but used as monitor for laptop in bedroom 99% of the time. My cable is good. TV is 1080 for sure. As far as Apex they filed for Chapter 11 shortly after i bought it! When i found that out i got TD to sell me an extended warranty $100 for 2 years. Maybe they could help me out on this?

I absolutely love the screen on the Infinity, hands down much much better than any other Android device out there and IMHO even better than the iPad Retina (which uses Samsung's PLS screen).
So as the title says, does anyone know who actually makes the LCD display for the Infinity? Does Asus make their own or source it from one of the main suppliers?
Probably Samsung.

Better then the Apple Ipad screen? I'm not sure about that. The Apple ipad 3 that I use for work some times has the most gorgeous screen. The colors pop and are bright and sharp. Everything seems dull on the Asus screen. I use Netflix sometimes and when you load Netflix that red screen comes up for a little bit. I had the Infinity and the ipad 3 right next to one another while loading Netflix and what a difference.

Hydis and Panasonic panels are mentioned in the kernel sources for the backlighting driver, so that seems likely. Panasonic might be "leftovers" from the TF201 kernel code, or maybe they are manufacturing similar panels. No idea, really.

I too compared them at the shop and I probably should have qualified my statement to restrict it to text rendering. I compared the new iPad, Infinity, my HTC One X and Nook Color. Images (I did not try video) on the iPad looked better but fonts and text (which is the type of content I consume the most) looked better on the Asus and also on the HOX. It could be the smoothing that Apple does. I used two apps to compare, the iBook vs. Moon Reader+ and Flipboard.

Has anyone else noticed quality problems with the HDMI out port? I posted the following over on the HBO Go HDMI thread but the more I think about it, the more I think it may be an issue with the phone rather than the apps.

Anyway, the HBO app works great on my Transformer prime outputting to my Samsung TV with only a thin black bar at the bottom.
Of course, I have the same Max Go problems as others trying this on tablets so thought I would just use my Photon Q. Unfortunately, the picture quality is terrible in both HBO Go & Max Go from the Q. It also has a very bright bar on the right side of the screen with the home and other soft buttons. Are there any output resolution tweaks possible to get it looking better?
