The maximum DVI/HDMI cable length from the graphics card to the monitor should not exceed 5 metres. Beyond that, DVI/HDMI amplifiers should be used.

The signal transmission of a 10 m long DVI/HDMI cable at SXGA ( CLK= 54MHZ ) is borderline. Due to line losses, mismatches and reflections that inevitably occur with this cable length, error-free signal transmission and thus the function of the monitors can no longer be guaranteed. 

The actual possible cable length depends on the cable and connector quality as well as on the image resolution (number of pixels) - the higher the resolution, the higher the bandwidth and the more critical the cable lengths become.

• Cable correctly connected to the unit?
• Supply voltage switched on?
• Brightness not at minimum?
• Press + and - during switch-on (activate INIT ALL menu) to perform a factory reset.

Due to the changeover to power supplies with green mode, whistling noises may occur during idling. It is true that the ECS100 has a higher noise potential in idle mode compared to the ECM100 (previous version without Green Mode). 

This is due to the "green" PWM IC used here, which switches to an intermittent pulse operation in order to achieve the maximum no-load current consumption of 0.5W, which then becomes audible via the transformer. 

The ECS65 (alternative to the ECS100) uses a different control IC than the ECS100, here the noise development in the lower load range is significantly lower. Unfortunately, a 100% elimination is not possible. 

This IC also switches to pulse skip mode in order to comply with the power consumption specifications in no-load operation, i.e. it no longer switches with the full switching frequency but with a significantly lower frequency, which means that the power supply only runs with minimal power consumption, but unfortunately with a certain amount of noise because the switching frequency slips into the audible range.

Pixelfehler bei LCD-Displays / ISO 13406-2

Since the technology of LCD displays is fundamentally different from that of the CRT monitor, this results in new conditions for the user and for service that correspond to those of flat panel displays. An LCD display always produces a razor-sharp picture. However, some settings on the unit are important prerequisites. A much-discussed topic with flat screens is always the tolerance for pixel errors. Due to the manufacturing process, pixel errors can never be completely avoided. All well-known monitor manufacturers agree on this. There are many articles about this in the trade press; however, experience has shown that customers are often unclear. The main component of an LCD display is the LCD panel. Until now, each monitor manufacturer has been dependent on the tolerance specifications of the panel manufacturer and has created its own definition on the subject of "defective pixels". The new international standard ISO 13406-2 should now provide clarity. This standard was developed in cooperation with monitor manufacturers, panel manufacturers as well as some specialist departments, e.g. TÜV Rheinland. Pixel defects are only a small part of the numerous requirements for LCD displays that ISO 13406-2 regulates; however, it is precisely this part that has aroused great interest among manufacturers. ISO 13406-2 divides displays into classes. Class I LCDs should have no pixel defects; in Class II, depending on position and colour, up to 5 pixel defects per million pixels are possible. A pure production of Class I panels is not possible. If a manufacturer wanted to offer such a flat screen, this would inevitably require "hand reading" in the production of panels. Further, considerable effort would be required for transport and stocking of replacement units. The prices for such a display would accordingly be many times higher than those of a "standard display". Another disadvantage of such a "hand reading" would be that all displays from (standard) class II upwards would basically have at least one pixel defect! Wortmann AG therefore adapts to almost all well-known monitor manufacturers and offers displays without proper subdivision into ISO classes. They must at least comply with class II.

Specifications / tolerances for LCD displays

A 15" XGA display, for example, consists of 1024 horizontal by 768 vertical pixels (pixel à picture element). Each pixel in turn consists of 3 sub-pixels, each with a basic colour (red, green, blue). This means that the above display consists of a total of 1024 x 768 x 3 = 2 359 296 sub-pixels. Even the failure of a single transistor (sub-pixel) is noticeable by a pixel error. Due to this high number of transistors and the resulting demands on the glass substrate and the process quality, pixel errors can hardly be excluded. Therefore, the following definition, which is derived from class II of ISO 13406-2, applies to the displays. If the number of defective pixels falls below the permissible number, there is no complaintable "defect".

The following pixel defects are permissible in relation to one million existing pixels:

• Max. 5 light or dark sub-pixels
• Max. 2 defective pixels (2 or 3 connected defective sub-pixels directly next to each other)
• Max. 2 connected defective sub-pixels in one "cluster" each (area of 5 x 5 pixels)

Monitors for applications with very bright environments.

Indoors, e.g. in studios with very strong lighting, high-brightness monitors are preferred. Brightness > 1000 cd/m². In outdoor areas and in direct sunlight, on the other hand, transflective displays always develop constant contrast. The disadvantage, however, is that the picture quality varies due to the principle. With high-brightness displays with LED backlighting, on the other hand, the picture quality always remains the same. It is essential to use a UV filter to avoid heat build-up. In combination with LED backlight and an automatic light sensor, optimum picture quality is achieved.

 Poor picture quality

With LCD displays, the optimum picture is only reproduced in scaled form at the maximum resolution (native). If, on the other hand, a higher or lower resolution is used, the picture is interpolated to the full display area, which can lead to a loss of picture quality (keyword: 1/2 or 1/4 pixel).

*Units marked 24/7 are suitable for continuous use (24 hours a day), provided that the environmental conditions, contents and content changes are appropriate. However, for the exact conditions of use, please refer to the operating instructions in the SR SYSTEM-ELEKTRONIK manual . 

Displaying a still image for a long period of time can lead to image sticking problems. When using the TFT continuously, a refresh time is required. After a static display of 5 minutes, 10 seconds of moving image should be generated. From time to time, the background and the characters (image or colour) should change. 

The combination of background and characters with large differences in luminosity should be avoided. Please adopt one of the following actions at regular intervals after long time displays: Screen saver (moving image or black pattern) or switch off the system for a while.

Skalierung

Auch mit PCAP kann man mehrere Touchmonitore einzeln einstellen und kalibrieren.

PCAP are also used as a replacement for capacitive single touch. These are recognised as HID mice and otherwise function without additional drivers. PCAPs are only recognised as MultiTouch from Windows 10 onwards.

Cleaning touch
Chemical resistance data - Surface

In addition to single- and dual-touch, MultiTouch operation (2/4 or 10-finger) is also available. 

• Oil mist, pharmaceutical, food 
  

Resistive touch offers protection in the most stringent hygiene requirements, such as in food production areas, chemical and pharmaceutical industries, as well as oil mist or water jets.

Die neuesten Betriebssysteme arbeiten Plug-and-Play mit unseren PCAP Touchscreen-Monitoren und erfordern daher keine Kalibrierung. Wenn Sie ein älteres Betriebssystem oder eine nicht native Auflösung verwenden, muss der Touchscreen möglicherweise  kalibriert werden, um eine möglichst Präzise Nutzung zu ermöglichen.

Kalibrierung unter Windows:
Der Touchscreen-Monitor kann über die Tablet-PC-Einstellungen in der Windows Systemsteuerung kalibriert werden. Der von Windows bereitgestellte Tablet-Modus optimiert den Computer für Fingereingaben und macht Tastatur und Maus überflüssig. Wenn der Tablet-Modus aktiviert ist, werden Apps im Vollbildmodus geöffnet und die Taskleiste sowie Desktopsymbole werden kleiner angezeigt.
Klicken Sie mit der linken Maustaste auf das Windows-Symbol in der unteren linken Ecke Ihres Bildschirms, um das Windows-Startmenü zu öffnen.
Geben Sie den Begriff Systemsteuerung über Ihre Tastatur ein oder wählen Sie den Ordner Windows-System im Startmenü aus.
Wählen Sie den Punkt Tablet-PC-Einstellungen aus, wenn Sie die Symbol-Ansicht der Systemsteuerung verwenden. Andernfalls wählen Sie bitte vorab die Kategorie Hardware & Sound aus.
Wählen Sie im Bereich Anzeigeoptionen, den Bildschirm aus, den Sie kalibrieren möchten. Klicken Sie auf Kalibrieren und befolgen Sie die auf dem Bildschirm angegebenen Schritte, um die Kalibrierung abzuschließen.  

Kalibrierung unter MacOS:
Die Kalibrierung eines Touchscreen-Monitors unter MacOS erfolgt über einen separaten Touchscreen-Treiber. Den MacOS-Treiber finden Sie hier: Download MacOS-Touch-Treiber. Die Treiber müssen extra gekauft werden. Befolgen Sie nach der Installation des Treibers die auf dem Bildschirm angegebenen Schritte, um die Kalibrierung abzuschließen. Stellen Sie sicher, dass die Quelle immer auf die native Auflösung des angeschlossenen Monitors eingestellt ist. Andernfalls funktioniert die Berührung nicht genau. Die Auflösung kann in den Systemeinstellungen unter Anzeigen in MacOS festgelegt werden.

Finger, latex (medical/food) gloves or conductive pens

Since the electric field of projected capacitive touch (PCAP) extends beyond the glass cover, touch is possible with bare fingers or gloves, as well as with conductive pens. These touch systems can be designed to detect touch with bare fingers as well as with thick winter gloves. In addition, there are also commercially conductive pens (e.g. Bamboo) for smartphones that function according to this system.

Material and thickness of the glove: nitrile (0.15 mm), cotton (0.31 mm), CPE (0.03 mm), PVC (0.12 mm)

On-screen keyboard

If the on-screen keyboard button is not displayed, right-click on the taskbar or tap and hold and select Show on-screen keyboard.

If you have switched on the energy saving mode so that the monitor switches off, the USB saving mode must not be activated.

This can be found under Windows -> Advanced Power Settings -> Advanced Settings -> Selective USB Settings.

•   Can be operated with finger, stylus, gloves, etc.
•   Surface made of hardened polystyrene

• Operation only by hand/finger
• Glass surface insensitive to scratches and chemicals

Maximum length for USB cable connections is 5 m.

For longer lengths, use a USB hub (amplifier).

In individual cases, ask the manufacturer whether this is also suitable for touch.

Extenders such as VGAUSB150 and other KVMs cannot accept USB signals (which is necessary for touch).

Only mouse and keyboard can be transmitted via such KVM. If touch is required, a pure USB extender should be used (art. no. 12041100). If you want to use picture and touch you have to use two extenders with two Cat cables.)

Bei Installation von Windows 11 müssen die Hardware-Anforderungen von Microsoft erfüllt werden. Neben mind. 4 GB Arbeitsspeicher , UEFI-BIOS und Secure Boot mit TPM-2.0-Chip ist die größte Hürde ein 64-Bit-Prozessor mit zwei Kernen. Microsoft akzeptiert mit wenigen Ausnahmen nur Prozessoren ab Intels 8. Generation.

Dies entspricht unseren IPC4 Panel-PC mit i5-Prozessoren. IPC2 Geräte mit Pentium, oder Quad-Core Prozessor erfüllen diese Anforderung nicht.

IPC Festplatte 

Üblicherweise arbeiten die bei uns verwendeten SSD Festplatten auf Basis 3D TLC NAND Flash Technologie.
Darüber hinaus sorgen die auch verwendeten NVME SSD für eine überlegene Geschwindigkeit bei Verwendung des PCIe Steckplatzes je nach IPC-Board.

Bitte beachten bei SSD: da für Firmware und Controller Management Zwecke Speicher auf der SSD reserviert wird, sind im Durchschnitt nur ca. 92,5% der Gesamtkapazität verfügbar.

Um RAID zu realisieren müssen zwei baugleiche Festplatten verwendet werden. 

Einstellungen im BIOS wie folgt:
 - RAID Level: RAID1 (Mirror)
- Status: Initialize
