Compared with manual strapping machines, automatic strapping machines can save you a lot of time and labor.The machine combines tensioning, cutter, banding in one machine, no need buckle or seals, while improving efficiency, reduce the waste of strapping roll and save steel resources. Also, without the need to connect wires, the portable electric baler can work anywhere, anytime when fully charged. This strapping machines use an LCD screen instead of blindly adjusting these parameters through knobs. You can adjust the strength required during the packing process and the time for welding the packing tape. Moreover, this will allow you to intuitively know the specific values you need in the packaging process through the data displayed on the electronic screen, and you can quickly set the same product next time.

The WoodRiver® Digital LCD Display Veneer Edge Banding Iron is the right tool for applying heat-activated, pre-glued edge banding to veneer-ply case pieces.

A built-in safety feature ensures automatic shutoff after six hours, regardless of use, unless manually turned off. Unit comes equipped with a 4" 9", 110V power cord, metal stand, and cotton sock for more delicate fabrics and films.

Banding could be minimized through changes in firmware/software and other manufacturing, engineering and QC program changes. Adding Several "dither options", that are noise filter algorithms, would allow the user to attempt to adjust the banding to a minimal nuisance level. Hence, the addition of the “Soft Dither” option that now appears in the 2407 A03 factory menu. Whether Dell or BenQ will diligently peruse this option for these panels or for future products is up to them. This could help compensate for the minimal banding in Desktop and heavy banding in Multimedia and Gaming modes caused by the faulty Faroudja video processing ACC chip feature.

LCD vertical banding is a flaw that can occur in the manufacturing process of the LCD panels themselves, and some LCD panels will tend to manifest it more noticeably than others. The panels that cause the most visible problems are usually weeded out in the vendor"s quality control process.

However, those that create just a hint of banding often pass through QC, since it is prohibitively expensive to discard all parts that exhibit flaws, which may have no practical impact on picture quality.

So, we end up with a situation in which some LCD panels, even within a given production run on one model, will have no banding at all, some may have a hint of it that does not rise to the level of a significant issue, and some may have a more visible problem that really does impair the enjoyment of the viewing experience. In the latter case, sometimes the problem can be mitigated with internal adjustments made by the dealer or vendor service departments, and sometimes the LCD panels or the entire unit need to be replaced.

1. Dell and suppliers should work towards providing consumer friendly adjustable LCD"s so they can adjust these LCD"s to eliminate or minimize the banding issues.

Thanks to RadxGe, for the definitive proof (picture) of the hidden menu obvious firmware update in the A03"s. A "Soft Dither" option has been added to A03’s. This is an option that most likely has an impact on banding and noise.

Some LCD panels offer several options, "Dither Options", to eliminate banding or noise by utilizing various algorithmic noise filters for use in different LCD applications.

Features, jack panel (connectivity), price and an Advanced Exchange Warranty that can’t be beat. Some of the competitor’s panels I’ve seen have major hitches in games and flaws that are very disturbing and some panels on the market would be considered unusable.

DisplayTester makes it possible to test almost every aspect of your device"s LCD/OLED screen. Using Google Cast it is possible to test the display quality of your TV. It is designed to allow full screen testing also on devices with soft keys (hiding the soft keys in ICS and later, immersive mode in KitKat and later).

In this quick guide we’ll cover what Dirty Screen Effect looks like, what’s happening on a technical level, and what, if anything, you can do to get rid of it. We’ll also touch on the notion of the so-called “panel lottery” and how that plays into how clean — or dirty — your new TV screen might look.

Dirty Screen Effect (DSE) is a term that’s used to describe an LCD panel that has inconsistent luminance performance across its surface area. It can appear as random splotches, uniform lines, wide bars, and, in some cases, vignetting (a slight darkening toward the corners). DSE once plagued plasma TV panels as well. But since those are no longer in production, we’ll keep this explainer focused on LCD-based TVs.

As a reminder, any TV that uses an LED backlight also uses an LCD panel, so TVs marketed as LED, QLED, and mini-LED are all susceptible. Due to what causes DSE on a technical level, some may argue it can only apply to LCD-based TVs. However, similar effects can be seen in OLED-based displays — thus the term is often applied — so we’ll include those types of TVs as well, but address them separately.

There are a number of factors stemming from the manufacturing of an LCD panel that can cause Dirty Screen Effect, from variance in backlight distribution to variance in TFT switching for sub-pixels, to variance in conductivity and/or capacitance of transparent electrodes. That’s super-nerdy, though, and the actual cause is less important than the common theme here: inconsistency.

In panel manufacturing, there are numerous variables that can be introduced that would cause an LCD panel to have groups of pixels that shine less bright than others. This variance is, unfortunately, part of the tech that makes our TVs. And the manner in which different manufacturers handle that variance is also … you guessed it: Varied.

Dirty Screen Effect also can be caused by damage to the panel in shipping or mishandling of the TV during the setup or installation process. Generally speaking, it’s recommended one avoids “pinching” or otherwise exerting pressure on the front of the TV screen.

From what I’ve seen, DSE — ranging from insignificant to severe — seems fairly common among newly manufactured LCD-based televisions, due primarily to the nature of LCD panel manufacturing. Very broadly, the less expensive a TV is, the more likely it is to exhibit some level of DSE. More expensive TVs are not immune to the issue, but some manufacturers have tighter quality assurance tolerances for their high-end products so — again, very broadly speaking — DSE tends to be less prevalent among those models.

DSE as a symptom of age is virtually impossible to track, however — again, anecdotally — I have witnessed DSE creep into a TV’s display panel slowly over time and worsen with age. I’ve seen it happen in TVs I own, TVs friends and family have owned, and TVs installed in commercial environments such as hotels and bars.

Unfortunately, there’s no way to eliminate DSE. Some websites suggest loosening the screws on the back of a TV to lessen the strain on the panel. We do not recommend this tactic as it could stand to void an active warranty. Also, it’s not very likely to work.

Most TVs offer a “game mode” which, due to its tendency to brighten everything on-screen, can help to obscure DSE. But this is really just a Band-Aid measure. The DSE is still there, but it may be less obvious. Another somewhat helpful tip to reduce the appearance of DSE in LCD panels is to view the TV from as direct an angle as possible. As you move off-axis (view a TV from an angle) DSE tends to become more obvious.

The so-called “panel lottery” refers to the game TV buyers unwittingly play when purchasing a TV. Sometimes you “win the panel lottery,” which is a way of saying that the TV you got was in especially pristine shape and shows no signs of DSE. It’s also a term used to easily express that there’s such a variance in panel quality that it’s virtually impossible you’ll win a perfect panel. In other words, it’s all up to chance.

The Hisense U8H matches the excellent brightness and color performance of much pricier LCD TVs, and its Google TV smart platform is a welcome addition. But it’s available in only three screen sizes.

The Hisense U8H is the best LCD/LED TV for most people because it delivers the performance of a much pricier TV yet starts at under $1,000, for the smallest (55-inch) screen size. This TV utilizes quantum dots, a full-array backlight with mini-LEDs, and a 120 Hz refresh rate to deliver a great-looking 4K HDR image. It’s compatible with every major HDR format. And it’s equipped with two full-bandwidth HDMI 2.1 inputs to support 4K 120 Hz gaming from the newest Xbox and PlayStation consoles. Add in the intuitive, fully featured Google TV smart-TV platform, and the U8H’s price-to-performance ratio is of inarguable value.

In terms of design, the Hisense U8H is not as svelte as our upgrade pick, but it’s plenty sturdy and doesn’t look or feel cheap. Two narrow, metal feet jut out from beneath the panel and steadily hold the TV. They can be attached in two separate spots, either closer in toward the middle of the panel or out toward the edges, to account for different-size TV stands. The feet are also equipped with cable organization clasps—a nice touch for keeping your TV stand free of cable clutter. Though the TV is primarily plastic, its bezels are lined with metal strips, providing a bit more durability in the long run. I moved it around my home, and it was no worse for wear, but we’ll know more after doing some long-term testing.

The Hisense U8H has some difficulties with banding, or areas of uneven gradation, where transitions that should appear smooth instead look like “bands” of color (sometimes also called posterization). Like many current 4K HDR TVs, the U8H uses an 8-bit panel rather than a 10-bit panel, which affects the color decoding and color presentation process. This is usually relevant only with HDR video and games. When playing games on the PlayStation 5 and Xbox Series X, I saw a few instances where the content wasn’t rendered correctly and displayed ugly splotches of color on the screen. However, this almost always occurred during static screens (such as a pause menu or loading screen); I rarely spotted it during actual gameplay. Hisense has stated that it would address the problem in a future firmware update, but at the time of writing it was still present. This is a flaw that may give dedicated gamers pause, but we don’t consider it to be a dealbreaker for most people.

I also saw occasional instances of banding with TV shows and movies, though they were few and far between. The U8H isn’t the best at upscaling sub-4K content, so videos with a 1080p or lower resolution looked a little soft. You can get better overall video processing and upscaling by springing for our upgrade pick (this is one reason it’s more expensive, after all).

Finally, like most TVs that use vertical alignment (VA) LCD panels, the U8H has a limited horizontal viewing angle, which may be a bit annoying if you’re hoping to entertain a large crowd. Our upgrade pick uses a special wide-angle technology to address this.
