Sharp LC-42D64U, flawed panel design?

1827 Views 11 Replies 6 Participants Last post by  jumpman23j
I just bought a Sharp 42D64U. It was going to replace my Sony 40V2500.


Upon hooking up the Sharp to my PS3 and computer (both 1080p via HDMI), I immediately noticed something was "off" about the IQ but couldn't quite grasp what it was. It just seemed "unsmooth". I thought I just need to tweak it. It looked OK after I tweaked the two HDMI for PS3 and PC separately, but still the Sony has better colors.


After all the tweaking and hiding all the wires again, I started looking at this unsmooth Sharp closer. It appears the Sharp panel's pixels are in a staggered configuration, whereas the Sony is in a perfect grid pattern. This causes fuzzy edges all over the screen. This is very noticeable when playing PS3 and using the computer, but not when watching a Blu-Ray movie. It is a problem for me because I sit only 3' from the set, this is strictly used for gaming.


I wanted to like the Sharp, I love the thin piano finish bezel and the extra 2", but really that's about it. I do not like one of the HDMI and component on the side, and the back component is shared with the composite (not that I'll use it). This is coming from a guy who loves to hate Sony (had a CRT XBR and 61" XBR projection fail right after the warranty expired), but now I have a new appreciation for Sony (yes I know they don't even make their own panels). I am very surprised that the Sony 40V2500, a discontinued 1 1/2 old design, has better colors than the Sharp, a current generation model.


Take a look at the attached photos. Please share your thoughts.


BTW, my Sharp has 712 serial #, and yes it displayed 1080p/24hz when playing Blu-Ray from the PS3.

it almost looks to me like staring at my old edtv compared to my 1080p. the pixels themselves look much larger. how does it look from far away?
Something is amiss with what your presenting. I am this very moment viewing an HD Movie in Dot Mode on a 57" Sharp panel and I can get within a few inches and I cannot see that damn pattern you are displaying - I can barely see a damn pixel in Dot Mode so I don't know what the hell is happening to yours but it sure is not representative of the 57" I view. I view at 8.5' with zero problems.


Perhaps I could see that in SD but I don't use Sd but rarely and have no need to view at 3' but damn I just put my damn eyeball up to the panel and cannot see that pixel structure your displaying. Sharp does a split double pixel fill. I challenge you to push HD in Dot Mode and photo that pixel structure as I can get within an inch and not see what you are displaying at all and I own three Sharps and a Sony.
"By dividing each pixel into two sections and developing an advanced driving system, Sharp's new Multi-Pixel Technology delivers more natural and accurate color reproduction when viewing the screen from virtually any angle. This technology improves extreme-angle viewing by about 60 percent."
What is the source you are photographing and it's resolution and how close are you placing that camera lense? Have you zoomed in with your PC software creating dithering artifacts? If you've magnafied the pic's you are falsely representing what this display is doing if you understand desktop publishing and the effects of resizing graphics without using vector graphics mathematically otherwise your presenting distorted pic's.

Normal viewing distances I don't think it would be noticeable, definitely not noticeable if you're watching TV. I don't watch TV on this set, strictly used for computer and gaming PS3 and Wii. I did say I'm much closer than normal viewing distance

As I said in my original post, I immediately noticed this "roughness", not amount of tweaking could get rid of it, sharpness on 0 just blurs it out. Those photos were taken at macro distance when I set out to figure out why the Sharp looked so, well, unsharp. Viewing photos of people, I immediately notice the eyes are not well defined with a stepped look (like anti-alias off vs on in a computer game).


I should have pointed out that with your naked eye you will not be able to see those pixel structures like that. No I did not zoom in on or blow up anything, those pictures were dot-by-dot at 1080p.


This will not be noticeable when watching TV or videos, but very noticeable using PC or in slow moving scenes from a video game. The text in the opening scene in Legos Star Wars on the PS3, this roughness is VERY noticeable even a few steps back from the TV.


I was just shocked at what I saw, shocked at how Sharp designed the panel they way they did. And what you quoted, I assume is from Sharp, they failed to do what they set out to do, the Sony has better color and viewing angle without Sharp's fancy staggered pixels, I'm guessing Sharp's marketing term for this is "Sharp's new Multi-Pixel Technology".


I don't know if your 57" or any other sizes share the same panel design. See it for yourself, take a picture at macro distance.


I did say in my original post I sit only 3' from the set, not exactly normal viewing distance. I only use this for gaming and computer, I sit so close so I can be "in the game"
I have a 58" Panny plasma in my other room, sitting 14' back is not quite "in the game" even at 58".


I returned it and paid 2x for a Sony 46W3000. I hate to give up a good deal, but for my use the Sharp was not acceptable to me.

Honestly, I think you got a defective TV. I have the LC-42D64U and have played both Unreal 3 and Scarface on it from about 4 feet away via my computer and didn't notice anything like that.


What screen resolution were you using on your PC?
Good luck with the clouding issues that affect the sony sets.
Lol every brand of set seems to have some problem
Yes you got that right, same as plasma vs LCD. Plasmas are dimmer, have yellowish white, slight flickering, weighs a ton and sucks down electricity, but offers more natural color, no blurring, has a certain 3D look vs LCD's flat look, IMO a better TV for watching TV than LCD. LCDs are much brighter, much better suited as a computer monitor and game console (never mind blurring, but personally I don't see any blurring), immune to glare. Pick your poison.


IMO as far as PQ in an LCD goes, Sonys (and Samsungs) have the least compromise, I am amazed at how smooth the Sony is viewing digital photos on it, super saturated color that looks unreal (I like the pop).


This so called "clouding" issue is silly. Sure switch to a blank input and crank up the backlight and all there's a slight uneven lighting. I tried that on the Sharp, it was 10x more horrible than the Sony, I'm guessing that's called banding in Sharp language. But this is a non issue, I don't stare at a blank input. It is the same as those taking a 30 second exposure with their digital camera with the lens cap on looking for amp glow or dead pixels. To me this is making an issue out of non-issue. The screen roughness on the Sharp was a real issue for me, as I could plainly see the fuzzy edges looking at stills and slow moving scenes in a game.

Hmm what do you suppose the defect is? You think my particular Sharp panel, the pixel structure was somehow misaligned on this one panel? I was running 1920x1080 off my computer HDMI, PS3 also at 1080p. It's the way Sharp designed this panel. Take a look for yourself, take a picture of your screen at macro distance.


Like I said the pixel structure I showed in those pictures are not visible with the naked eye, but it did translate to fuzzy edges when viewing still photos and slow moving scenes in a game.

andy, you said sony doesn't even make their own panels? Than who does?
