ViewSonic PX701-4K 4K UHD 3200 Lumens 240Hz 4.2ms Home Theater Projector with HDR, Auto Keystone, Dual HDMI, Sports and Netflix Streaming with Dongle on up to 300 Screen

Im dunklen macht der Beamer ein gutes helles Bild an die Wand, auch wenn es leicht dämmrig ist, kann man noch schauen. Er ist aber offensichtlich nicht vergleichbar mit einem Fernseher und tagsüber muss man das Zimmer verdunkeln. Was nicht in Ordnung ist: Die Linse war beim Auspacken voller Staub. Also war erstmal putzen angesagt. Nach kurzer Zeit hat der Ventilator einen Defekt bekommen und angefangen zu Quietschen. Er hat kein WLAN, daher laufen laaaange Kabel durchs Zimmer.... Mittels HDMI hab ich ihn an den PC angeschlossen. Aber aus irgendeinem Grund hat er sich nach einer Zeit mehrmals, einfach so aus dem Nichts, nicht mehr mit dem PC verbunden! Als ich das HDMI Kabel an den Monitor angeschlossen habe, hatte ich wieder ein Bild. Dann wieder an den Beamer angeschlossen und keines. Obwohl das selbe Kabel mehrere Tage mit dem Beamer ging. Neues HDMI Kabel ausprobiert. Monitor ging Beamer ging. Danach wieder das selbe Spiel wie beim ersten HDMI Kabel. Der Ton geht übers HDMI Kabel. Die Beamer Lautsprecher sind wirklich zu schlecht und die kann ich nicht empfehlen. Es war mir letztendlich auch zu blöd, dass ich erstens so ein langes HDMI Kabel besorgen und, dass ich es durchs ganze Zimmer zu meinem PC legen musste. Habe den Beamer ca. 3,2m von der Projektionsflache auf einem Regal nahe der Decke gestellt. Das Bild war einfach zu klein. Ich denke man braucht über 4m damit man eine ansprechende Größe erzielt. Außerdem musste ich die Trapezkorrektur ausreizen und hinter die Hinterbeine eine Kiste stellen, wackelige Konstruktion...aber ohne wurde das Bild größtenteils an die Decke projektiert. Die Korrektur führte zu einem furchtbar störenden grauen Rand um den Film (und das projektierte Bild wird dann natürlich um den grauen Bereich nochmal kleiner). Ich habe ein langes Holzbrett vor den grauen Rand stellen müssen, damit die >10cm überdeckt wurden. Die Fernbedienung ist eher minderwertig und nicht gut designed. Die Knöpfe sind so weich, dass ich immer öfter drucken musste damit sich Mal was getan hat. Alles in allem einfach nicht am den Stand der Technik. Werde mir einen anderen Beamer mit WLAN zulegen und hoffe er hat nicht so viele Makel wie dieser. 790€ ist er mir jedenfalls nicht Wert.

This is bright and clear

I wanted to add a review for using this as a computer monitor in case others were thinking of the same. The unit is very bright. I dont have to close my windows if Im looking at high contrast things like text. Color isnt maybe as good as more expensive projectors, but I found it to be fine. I found that using 1080p resolution for desktop use was better than 4k as the pixels are a bit fuzzy at that resolution which makes text not look as good. This is due to the pixel shifting tech used (any 4k projector sub $1600-2000 will use this). The screen is very detailed at 4k showing movies and games, however, and the pixel shifting kind of adds a bit of an anti-aliasing effect. I dare say I might actually prefer a pixel shifting projector for computer use as it lets you decide between 4k 60hz and 240hz 1080p with both modes having their own strengths. I feel I have two monitors I like for different reasons which is cool. There is just a slight perceptible lag on 4k, but its really not bad. I dont notice any at 1080p 240hz. And it really does go that high, the difference between 120 and 240hz is noticeable, and it looks really good at the high refresh rate. I actually prefer it over my 144hz 1440p monitor. I dont think this would be good enough for esports compared to a 240hz monitor, but its very close. Remember to use the game mode. Overall it works better than I expected as a computer monitor and Im happy with it and feel it was a good value for the money. Other thoughts -I wish the power plug was longer. Im not going to install this in ceiling, and I had to use an extension cord for it to reach down to a plug that is only a few feet horizontally away. -The remote is a bit old fashioned looking. Not a big deal to me but I think ViewSonic should update the design. -Sometimes the unit makes a strange whirling sound that is annoying. Usually it doesnt and it has done it less as I have used it. Its not the fan, it sounds like something is spinning that is not lubricated. When this isnt happening I found the fan noise to be fairly low and constant. -Its very easy to switch between modes like normal and eco, needing only one button to be hit. This is really nice since the bulb has a lifespan. If I know Im going to step away from the computer for a few minutes or am going to just be looking at text I can switch it to super eco in two seconds. -SuperEco at 240hz flickers, changing to a different refresh rate fixes this. Some tips: -Dynamic Eco is basically as good as normal in terms of color and brightness at least when its showing a bright image. Thats my main setting. I think it just dims when the screen is dark. It is better than eco (but not super eco) in terms of bulb life according to the manual. -Make sure your resolution is 1920 by 1080 if you want 240hz. If its 1920 by 1200 if will default to 120hz. -if the projector is located above you, make sure you turn the projector upside down. It will need next to no keystone correction that way which keeps the image at native.

Ive been using it for 6 months now and Im very happy with it.

using this for movies outside and it works great. plenty bright if used in the evening when the sun is going down.

My Home Theater Is Prime Again.

[Note, as I write this the unit is marked down to $646 brand new. At that price its worth a gamble as my unit had small defects which may have affected the entire output.] This projector is an example of the cart before the horse. Excellent 4K clarity, brightness, remote, menu response time, plus 3D. However the ground base of any unit is the brightness (ie white) uniformity, which this model has no better of than my old $400 projector which has been serviced multiple times. Projectorcentral reports its uniformity as 60% -- a poor mark, but Im not confident my unit even reached that. The far left side was always brighter than the remainder of the picture, and in mainly white or light scenes such as snow, sky, or sand there was a visible scoop of bright bias. Next, and at least as problematic, was the focus-zoom rings equation. The zoom ring was very stiff and jumpy, making it impossible to mask the pixel grid (screen door effect) as normally with a DLP projector you focus and zoom to maximum sharpness so that text aliases, then delicately dial down the zoom so that text is naturally rounded, thus reducing the pixel grid to a tolerable visibility of ~9 distance (which isnt affected by the size of the screen projected). However the focus and zoom were so fiddly on this model that they constantly borked the convergence and uniformity further, focus messing up the left side of the image, and focus the right, that I had to leave it at maximum sharpness, meaning a constantly visible screen door effect on any light surface. Crap. Then there were the menu lockouts. Color tweaking possibilities for this model are more than adequate when available. For whatever reason, more often than not they would be locked out, so, eg, Id play a film and the Movie color mode Id had it on previously would now be locked in place, so not only could I not tweak it, I couldnt select another mode or temperature profile. Sharpness seems only to be available for native 4K content too. Lastly, a couple glitches. My USB port would not power anything. I just turned it off via the menu before it created additional problems. The Blank feature would instead turn the projector instantly off -- which is not merely irritating but potentially destructive as projectors are built to run the fans for 30 seconds to a minute while powering down in order to expel pent up heat. Bonus info: I couldnt hear the 4K shift, which is to the good, as thats a common complaint. High altitude mode, if youre in the mountains or just somewhere very hot, is quite loud as is pretty much always the case with these small projectors, so youll need a hushbox if youre running it.

Bin hoch zufrieden. Man sollte keine Wunderdinge erwarten aber HD und 4K sind für das Geld unschlagbar

very crisp images. solid mounting. handy charging port on the projector for airstick etc. no issues whatsoever. very happy with the purchase. takes a couple of minutes to turn off completely. the onboard speaker is useless though.

Ive had this for about a month now. Ive installed many projectors and have some experience here. Overall its a good projector, the throw distance was perfect for what I needed. Projecting onto a 110 screen from about 10 away. - Hanging from ceiling. Im using this for daily use. Audio for my setup goes to a soundbar from the 3.5mm jack for normal viewing. When I turn on the receiver, it interrupts the audio from the HDMI and the audio only comes from the surround speakers at that point. Works well and sounds great when needed. Pros: Excellent throw distance for small rooms. - Very forgiving throw distances. - For my screen size, anywhere from 108-140 throw distance will work for 110 screen. Plenty bright - However it is not powerful enough to overcome the room lights I have. You still want to use this in a space you have good control over the light. Its 4K Its 3D - Yes, this works well, but I did find myself inverting the images on a couple movies. - Used DLP Active shutter glasses. - https://www.amazon.com/gp/product/B08C9SWQKM Its small - This is good because I have a low ceiling where this is installed and need people to be able to walk under it. Cons: Cant get this to power up or down with the Xfinity remote (Volume does work after trying a dozen codes). - Still working on a remote config for my system. No optical out. (Would be nice to have for added connection flexibility.) When viewing in 3D, it puts the lamp from Eco mode, back to normal, and does not put it back when 3D viewing is over. This is the highest brightness setting and uses up lamp hours quicker. - Use one of the Eco modes for longer lamp life. Adjusting the screen is a little cumbersome, but doable. Focus and zoom are stiff, making it hard to really fine tune it. Fans can be a bit loud. They are worse when lamp is set to Normal. Overall, not bad. The price point for being a 4K projector is good. Its far from perfect, but given the cost and what it can do, Im happy with it so far.
