Ich muss zugeben, dass ich bei "The Wall" zu optimistisch war.
Sowohl die Performance ist noch nicht überzeugend als auch der Preis ist Lichtjahre-weit jenseits von Gut und Böse.
Das wird wohl doch noch einige Jahre dauern bis so ein Teil für uns "Nicht-Multi-Millionäre" eine realistische Option für ein Heimkino darstellt.
Modular video walls are most certainly not all roses and they never will be either
The primary issues as of right now and the foreseeable future include:
(1) PRICE --> SAMSUNG The Wall prices range from $350,000 - $1.2 MILLION+ and with SONY CrystalLED (previously called CLEDIS) prices start at circa $1.5 MILLION Where in fact that 'ultimate' CHRISTIE projector, despite being expensive, in fact costs significantly less than a SAMSUNG The Wall and/or a SONY CrystalLED display of a similar size screen!
(2) AUDIO PERFORMANCE --> You have a giant non-accoustically transparent and acoustically reflective panel on your front wall... What about your audio system and audio performance? Where do you position your front soundstage LCR speakers? There are audio system design solutions to achieving great sound quality with non-acoustically transparent displays, wherein I myself have personally designed, built, and successfully tested these; however in all instances there is a very considerable cost implication and this involves replacing the entire audio system... otherwise you will be severely compromising the audio performance of your home theater... neither of which most people are agreeable to doing
(3) HEAT PRODUCTION --> These displays output A LOT of heat, but unlike projectors you cannot choose to enclose these displays or situate them outside your home theater within a climate controlled environment. They are situated on the front wall of your home theater generating as much heat directly into your room as multiple multi-kilowatt heaters!
(4) UNIFORMITY / SEAMS / PIXEL DELINEATION ISSUES --> Interpanel seams and uniformity are a huge problem that afflicts all such products. I have yet to see ANY of the MicroLED or LED video wall products wherein you can't see the seams and/or the panel structure. Furthermore, with products that have pixel pitch size larger than 1mm you can delineate the pixel structure from typical viewing distances. The individual panels also have the potential to degrade at different rates leading to exacerbation of interpanel uniformity issues over time, and requiring panels to be replaced at high cost. With SAMSUNG The Wall for instance you have to purchase 'spare' replacement panels because of this at the outset.
In short, display wall technologies with never completely replace projectors in the home theater setting. What will happen is that display walls will simply attain a share of the market, in fact a niche, and reside alongside projectors and TVs. So any talk of video walls making projectors extinct is quite simply not true

Den Punkt Wärmeentwicklung hatte ich bisher noch nicht "auf dem Schirm", das ist natürlich auch ein valides Argument.
Und umso mehr Wärme je größer die Bildfläche.
Ob das mit der Panelalterung so kritisch ist … ich kann es nicht beurteilen, eigentlich sollen die anorganischen LEDs aber alterungsstabil sein.
Wie auch immer, wir können Projektoren wieder von der Liste der vom Aussterben bedrohten Gattungen runternehmen.
