DELL Venue Pro 7140 visible digitizer grid - Venue Pro General

Hi i buy a DELL Venue Pro 7140 on internet auction, I think that it have not original digitizer because I can clearly see a digitizer grid on screen, I attached a photography but I can’t catch exactly how it is look like. On photography You can see only some horizontal lines but on screen all matrix I visible.

Grainy screen?

I see light vertical lines on the screen. They are more visible on a white background. I dont have to hold it too close to my face to notice it, i can see them even at distance of 10 inches or so. I went to bestbuy, and noticed that their display model had the same issue.
I have playbooks and touchpad in the house and i dont notice this behavior on those tablets, even if i look really closely. So its not a matter of screen resolution. It seems to be some defect with the screen. Maybe because its not a LED or IPS display?
I talked to Acer customer support, they told me to send it in for repair. I asked, whether i will get a replacement or not. He said they dont offer refunds or replacements under standard warranty? I dont want to send in my tablet and pay for shipping, only to have them reinstall the OS and send it back. So should i even bother?
I searched on different sites and forums ,and no one seemed to have mentioned this issue. But on Engadget review, they state "Pixels visible with naked eye" as one of the negatives, and the tablet i saw at bestbuy had the similar issue, so it can not just be me only. Maybe people dont really care to notice it? You will notice it more when you tilt up the tablet a little.
unfortunately, it's a "feature" of this tab. I knew ahead of time before I bought my tab because of a review but didn't think I would notice.
I only notice it now with the screen off or outside.

How do u notice it with screen off?? I am not talking about the "dots" on the screen which can be seen with screen off. These are very light vertical lines placed VERY close to each other. Maybe they are just pixels, but why are they so visible? My macbook pro 13" looks better and it has same resolution

do not compare laptop with tablet. i'm sure all of a500 have same issue.
if u don't like its screen u should sell it and buy another tablet.
^ Not true. Neither my A500 or A101 suffer from these vertical lines the OP describes.
Lots of times eexplain a issue diffrently then others..
If what you are seeing is consistent. if its a kinda exact set of dots and lines in a grid on the device.. this is the DIGITIZER .. this can be seen easly on the a500. all devices have it but for some reason the grid is some type of reflective material instead of dull . this makes it easy to see on the iconia..
This is a very common complaint about the a500 tablet... to know if its this for sure go out in the bright sun .. tilt your screen around and it will come into very clear view...
good luck and i do hope this is what you are seeing. if not sending it back might be the only option . if your not under warranty you can try opening the case and check the display connectors.
He explicitly said it wasn't the digitizer, or "dots" as he put it.
same here
I cansee all the pixels with my naked eyes. Its worse than my arm11 cheap android phone..

Its expecially noticible on white background or light colours like this xda forum web page. Don't look close to the screen, its hard to see it like that, but just looking at the screen normally, I can see full of pixels..not a HUGE problem, but its a little bit annoying..

oops i do not know how i did not read that.. Sorry ..
call me dumb blonde .. Giggles.... I once had a issue long ago with the cable from my screen to the mb came loose.. took it apart and pushed it back on. and a drop of silicone to hold.. not stupid tape as acer does.
Thanks for the input everyone
I do believe you're seeing the red subpixels of the LCD. While they are extremely tiny, they seem to be slightly more noticeable than the blue and green, especially on a white screen. These are the only vertical lines I can think of besides the obvious digitizer lines you see when the screen is off under sunlight.

Yea upon looking very closely, they seems to be the pixels. Maybe they are more visible on this tablet because its just an LCD display as opposed to IPS as found on other tablets. Like i said, i noticed same thing on bestbuy display model as well.
With apologies to Arthur C. Clarke:
My god, it's full of pixels...
My mind is blown... people are seriously able to detect individual pixels when there are almost 150 per inch on this screen. I'm not sure I could see 150 individual anythings in one inch.

There is NOTHING "wrong" with it, it's just the way it's been designed. Whether you like that or not doesn't have a damn thing to do with that. It's not "wrong".

Well, then its not well designed. That's what i wanted to say. People shouldn't be able to see full of pixels on this 720p pixel resolution on a 10.1 inch screen. Compare with other tablets; they may have pixels in texts, but not in any light background.
I can only see the subpixels with my nose to it on a bright white screen. At 149 ppi, this is pretty normal.

NExus 7 hydis screen

HI Guys
My nexus 7 digitizer is now broken , the screen is ok but only with a fine crack but the touch is completely busted
anyway the repair shop offered me a replacement for both screen and digitizer but unfortunately i lookied it up and the brand was ( CHUNGHWA) the original is (HYDIS) and i could not find that hydis anywhere
my question is , did anyone replace the screen with that CHUNGHWA and found any difference regarding color depth and quality , resolution ...etcc...? because one of the main reasons i like my nexus is the screen
i was also offered another generic screen replacement from another guy that told me that it was a copycat for original for a mch lower price but i am not sure
PS , i also found a digitizer online but i am not sure if the digitizer onl ycan be replace
thanks a lot guys

Screen replacement

Hi,
Dropping my phone was the worst thing that could happen with my phone.
I found someone who would do the screen replacement and after nearly two months he finally returned the phone two me.
At first glance it seemed ok but closer inspection have shown me that:
- the panel used was JDI instead of LGD so a japanese panel instead of the 'original' LG
- serious screen bleed contouring the whole screen
- highlights on the screen, points in the screen where I can clearly see the backlight being brighter than everywhere else
- luminosity is lower than the original.
The last two points are very annoying. I compared my phone with a phone displayed in a shop and I see that the screen on the shop's phone is brighter that mine, even without adaptive brightness and @ 100% luminosity.
Could this be due to different panel manufacturer (JDI instead of LGD)?
The screen bleed could be due to the screen being badly glued but I am not sure...
But the bright speckels are annoying also. In bright areas this is very much noticable, a white picture shows two small areas brighter which indicates to me that the back of the panel has something behind that 'pushes', hard to explain.
Anybody had similar issues or had his screen repaired?
You can see my issues in the attached screenshots...

I don't think your issues is the panel type, i replaced mine and got a JDI from eBay. I don't notice any difference from my old one, which was not JDI. I would say you just got a poor screen. Not the fault of the installer either, i would try to get hold of the screen seller, or just accept the loss and replace it again.

I can agree that the panel type is not the culprit but the screen bleed is definitely the installers fault.
I am not very happy replacing it again as the total cost would mean that I could have bought a new phone for the same price...
My feeling is that the seller of the screen has delivered a used screen and damaged the silver back of the panel by removing it from the old device (the bright highlights could be from a prying tool used while recuperating the screen.). Too bad , lesson learned = do not drop the phone as the screen shatters very easily and when repairing, find a reliable repairsman...
Accept the loss seems to be the only option in this case...
Maybe I will have to disassemble/assemble the phone myself and do with with extra love and care and sense of detail....

Since the digitizer comes glued to the glass I'm more inclined to blame the screen/seller than the installer. But you know the saying... "If you want it done right...". All the best on getting it sorted and working properly.

Lcd change

My phone fell on the floor and screen broke.
I want to buy a new one on Aliexpress and i have 2 questions.
1. Is it better to buy the screen with the frame or just digitizer and screen and if anybody changed theirs if you have any advice.
2. I hade a white/rose gold combination and now i would like to buy black front instead of the white one. I think that there is no difference but i would still like to ask if i would have any problems just becouse of the color?
Thanks!
Hello,
1. I suggest you get the one with the frame > much more easier than without it, and removes the possibility of making a horrible mistake.
2. I don't think the colour will cause any problems, it's much more easier to manufacture the same screen with multiple colours than to make totally different screens. So I think you are good to go. But I can't cover my opinion with a fact, so there's that.
Hope I helped ya bit.

Hi its better to buy one with a frame and the color doesn't matter but since you have the gold version. I would suggest you stick to the white its looks much better. I did the same an bought an LCD with frame from Aliexpress and replaced it myself. Here is a video that will help you disassemble your phone https://www.youtube.com/watch?v=l_VMcIX0hJY I would suggest you first watch the video before you start. I did the same before i started. You can follow and pause at each step. Good Luck. Its an easy task but one point to note is the fingerprint sensor is easy to jump out of its connector. I would advise to test the screen before you screw the phone back up.

burn in? what to do

Hi guys, I was using Google keep and the background in that app is gray. I can actually see the burn in typing this as well on the xda app as the color is similar. I have a picture taken with another device in low light. Zoom in a bit to see more clearly. It looks like an outline of a smartphone in navigation menu settings or something like that.
Is this burn in? What do I do?
Well if it is burn in then there's nothing at all you can do but a screen replacement, that's what happened to my last OnePlus 8 pro but I didn't bother to replace screen so then I got the oppo find X2 pro and i wouldn't think about going back to oneplus
When your phone is on are there any screens you can show which can show this?
Could try a screen test program to push colours to all pixels on the screen.
Or power it off for a day, see what it's like after that.
Definitely shouldn't be happening.
What did OnePlus say?
