Take a close up picture of a static completely medium gray screen in a room with low ambient lighting. I have never encountered an OLED screen over a few months old that did not show some signs of it. You probably just don't notice it.
Samsung makes good displays but they can't fix the...
"Modern OLED displays" as in ONE display?
I guess the Nexus 6P released 4 weeks ago is using a non-modern 5.7" 2560x1440 display.
Anandtech's data does show the S6 is accurate but not as good as an iPhone 6.
You want to see burn-in? Go to an AT&T store and look at a Galaxy S6 demo...
Older generation as in a phone that was released 4 weeks ago?
I have used GS5 and GS6. The FACT is that as a whole AMOLEDs can't get as bright as an LCD at similar power consumption levels. The another FACT is that they will suffer burn-in from any static image. Yet another FACT is the blue...
I own a lumia 930 and a Nexus 6P which are both oled and burn in is a real issue although it hasn't happened yet on the 6P since it's three weeks old.
I would prefer a good LCD. OLED has poor color accuracy, uneven whites, and color shift at minor off axis angles. Burn-in is a real issue...
No, budget isn't that important, although <$1500 is probably good. The image retention is mild and only shows up on certain colors / scenes, like it only affects some sub-pixels. I don't know if the anti-glare coating has anything to do with image quality really. I don't mind the AG coating and...
Hi all,
I have an HP LP3065 which has some permanent image retention (been there 2 years and tried all kinds of things), so I am looking for a replacement.
Problem is, I don't know what really is a clear upgrade. I'm really just looking for the best image quality overall and would rather...
No, mechanical engineers shouldn't design cables and connectors by themselves. The cable and connector geometry affects the characteristic impedance of the cable and simply reshaping a USB 3.0 connector or changing the cable geometry of CAT6 would most likely harm operation. The fact that the...
No, LGA is electrically superior to pin contacts. There is much less inductance in the connection that way. AMD didn't change because they were being "cheap and cheerful".
This is also basically an article about India.
I am sure the useful life of an engineer is greater than 15 years, however, after 15 years they probably become less tolerant to working crazy hours.
I have never seen a black anodized aluminum product that wasn't susceptible to scratching.
Apple's RF engineers must hate the design guys. So much easier to build a well functioning device with a plastic enclosure.
And we have at least one person here who understands exactly what will happen.
They will create a cheaper plan with unreasonably low data cap. Then everything else will be equal to or higher than you pay today basically. Have fun with your "fair" tiered data.
If anything there should be...
Are you dense? These GPS recievers were developed BEFORE LightScam.. er I mean LightSquared came up with their stupid plans. How the hell are they supposed to predict there would be very high power transmission on a neighboring spectrum designated not for terrestrial use.
If LS was going to...
Sorry, if you had any clue how RF works you would know that there is no such perfect solution for every product.
Lightsquared's signal is so strong compared to GPS that intermodulation products from their band just being nearby will degrade GPS reception, filter or not, in most devices...
This whole thing is a joke. Lightsquared knew exactly what they were getting into when they bid for this. It doesn't take an RF engineer (which I am sure they had on staff anyway) to figure out this was going to cause significant problems in the GPS band.
Filters are expensive and imperfect...
Even if they are, the result will be the right thing. This is physics, you can't make these issues disappear. It's unfortunate but anyone who believes LightSquared was blindsided by this possibility is crazy. I am sure they had RF engineers on staff before they bid for this spectrum.
Some cars can be obnoxious but it's pretty rare IMO. The biggest problem are the idiots with Harleys and straight pipes driving at like 7 AM. So much noise for such a slow bike.
I have a 3.5 year old LP3065 which is out of warranty and showing what looks like some image retention or dim spots that only show with certain colors (mostly gray).
Has this happened to anyone else, and is it possible it's something fixable (i.e. not the panel)?
P = I * V
for a given power consumption as voltage increases, current must decrease. That's what the original poster probably meant.
With that said, it has nothing to do with this situation. GPU voltage is a bias voltage and will actually raise quiescent current draw.
This is pretty clearly a hardware problem, imo. It is probably a transistor which fails as a short which causes the current limiting resistor to burn.
Yeah it could be caused by the driver and overvolt, but the bottom line is the engineers failed to specify components that were adequate to...
Small technical issue with the article. The response from the Audio Technica support rep is incorrect; headphones with identical sensitivity (db/mW) will require the SAME amount of power regardless of impedance (assuming the amplifier can provide it) because power is the product of voltage and...
With FIOS you pretty much get exactly what you pay for, not like most cable. I know that GPON fiber is technically not dedicated, however I live right outside of NYC and I still reach my 25/25 even during peak hours. I used to have Optimum before this and I had 30 Mbit/s at 3 AM and 4 Mbit/s at...
Problem is, Silverlight is basically .NET for the web and that means it will likely never have good support on platforms other than Windows. I am aware of Moonlight/Mono but it lags behind.
Oh and I forgot to add that it's level of performance is not even close to justifying it's pricetag. Yeah so it's electric... if you want to be economical buy a Nissan Leaf or something.
The problem is that it's basically an inferior Lotus Elise with all of the fragility that chassis has, combined with more weight and a much higher pricetag. Go look up what happens to a Lotus Elise/Exige in a bumper to bumper accident, if the clamshell is damaged the repair bill is insane.
I use Acer 22" TN monitors at work and a 30" IPS HP LP3065 at home. The colors and accuracy suck on the TN panels... BUT I find they are much easier on the eyes for some reason.
I have the same experience with my TN-panel laptop vs my old 19" Samsung IPS from 2001. IPS seems like it makes me...
The green things are probably not regular capacitors, but some kind of filter element with a ferrite or inductor inside. Capacitors don't make mechanical noise and the only way to "overload" one results in death. The inductors could probably be increased in value somewhat with no problem since...
The two loud noisemaking parts are indeed inductors as I suspected and probably undersized and the core is saturating. The green parts are more difficult to identify because they are in an epoxy casing but it looks like they are some kind of ferrite / 3-terminal cap / LC-filter or perhaps a...
My HP LP3065 is also grey at an angle, unlike my previous 18.1 IPS which was purple from the left and orange from the right. It is possible I just haven't been able to find an extreme enough angle to see it, though (cramped desk area).
I just wanted to weigh in on some of the perceived problems of the 2690 and whether they are specific to this model / panel or not.
About 6 years ago I bought a Samsung 180T 18.1 LCD. This was one of the few early Samsung made IPS (not even S!) panels, before VA was mainstream. It exhibited...
I just bought an LP3065 (30") and the first one I received had a stuck red subpixel on the far right side of the screen and I was unsuccessful in unsticking it, so I received a replacement. This replacement has a stuck green subpixel in the center.
The question I have is, does anyone think I...
