5. How to bear the maintenance Freight
Under warranty, clients must do the customs clearence according to the value of goods we require and pay the return shipment cost. We provide free repairs for customers and send you the items with recent order together, rather than send the repaired goods alone,and we will bear the delivery costs back.
7. Since the total capacity of 4 output controller is 2.3m px, we can not use 650,000 px on each output?
If you use 650,000 for port 1/2/3, the loading capacity of port4 will be 2,300,000-650,000*3=350,000px We recommend you average the loading capacity of all the outout ports。each output port capacity will be 575,000 px
2. How long is the returns process
Processing returns may take up to 14 business days from the day we receive your return. We will email you to confirm once your return has been processed.
4. How long is the warranty
In normal warranty period (modules, power supplies, LED strips with 1-year warranty; control cards, video processors with 2-year warranty), we are committed to providing customers with free maintenance if there are quality problems under normal use.
6. MCTRL 4K can really do 7680 height, if we have a graphic card that can do this?
Yes, need graphics card feed this input resolution to MCTRL4K, you can check the Ultra-High resolution generator setting at https://www.novastar.tech/downloads/controller/
8. If there is any important for ethernet cable we use?? Cat5 or Cat 6?
CAT5 is enough, but the CAT6 is better
9.if I use frame rate 50 Hz how many cabinet (p3.91)connect single network port?
The capacity of the output port at 50hz will be around 780,000, use the 780,000➗cabinet resolution you will get the cabinet number
11.If I use vs4x as main screen , then use 660 as backup screen. why got color not match and delay problem?isn't bit problem or hz problem?
Since the processing algorithem and hardware is different Never use different type controllers in the same project,
13.if I use 30hz and 8 bit colour depth port capacity 1300000 so more connected in a single network port. why you preferre 60hz?
It is about the customers requirement, and different area may have different requirement, China/ US/ SEA we use 60hz, europe often use 50hz. 30hz is not used that often since the screen may have visible flickering
15.why the usage rate is 93.6%?
93.6% is an average usage rate that we get from the test, and with this usage rate we give the 650,000 px,
10. Does the connection type between cabinets have effect on our image ? For example I can connect 2x3 cabinet (width)x(height) as "S" and "U" figure. what is the difference ?
Conncetion type won't affect the image, the "s""u" both will work, it is just let the system know the dataflow
12.you are using 93,6% usage rate, is it reasonable to use less usage rate per port?you are using 93,6% usage rate, is it possible, to use 100% usage rate?
93.6% is an average usage rate that we get from the test, and with this usage rate we give the 650,000 px, you can't get 100% usage rate(transmission distance/ cable quality etc..)
14.If my Cabinet Pixel 128*256 so how many cabinet can connect in 1 port?
cabinet number= 650,000 / (128*256)
16.so we are currently talking about loading capacity per ethernet port?（Formula）
YES
17.For the MCTRL 4K, the max width is shown as 7680, is that achievable on the HDMI 2.0 input, or do you need to link the two DVI conectors?
Both HDIMI and 2*DVI-D can realize this,93.6% is an average usage rate that we get from the test, and with this usage rate we give the 650,000 px,
19.Is that always a square? could it be a rectangle if it was 2*3?
not a square, is about a rectangle area, 2*3 is correct
21.to confirm the image pixel loading capacity, is it total maximum in one direction squared?how come the 1*8 in the example didn’t become 1*10?that bit is not clear
is not about a square, is about the rectangular, so the 1*8/1*10 is rectangular area
23.What is maximum distance cable we can use sending controller to receiving card
100meters(ethernet cable)
18.Why is the total loading capacity calculated in rectangles?
it will be 650,000/width*height of the rectangle area of this output port
20.What about if use Blank option in cabinet Data patching? even if it is not rectangle?
blank area will also be calculate in the rectangle area，the rectangular size will be define by the position of the outermost cabinet
22.Can you define what is a frame rate and what importance it has with the screen output ?
Depend on the customer requirement, higher frame rate will have more frame picture send to the screen,China/ US/ SEA we use 60hz, europe often use 50hz.
24.is there a built-in scaler for the 4k?
No, Mctrl4K is just a independent controller, the NovaProUHD-Jr is the 4k all-in-one
25.in 1*8, it doesn't need to add any cabinets to make a rectangular shape
It is a rectangular shape actually
27.is it advised to use the maximum resolution at 93.6 of the bandwidth? could a poor connection cause issues?
Poor connection will affect the usage rate, it is about the data transmistion is stable or not. 93.6% is an average usage rate and the 650,000 is the most safe number
29.on a vx4s can I load 3 ports with 650000 and the fourth port with 350000.
If you use 650,000 for port 1/2/3, the loading capacity of port4 will be 2,300,000-650,000*3=350,000px We recommend you average the loading capacity of all the outout ports
31.I have seen in some cases even it is showing the loading capacity over loaded but the screen is working in some cases, is that ok?
Never put yourself into unknown status, please load the screen within the loading capacity
26.For MCTRL4K to 7680 do we need to use two input to atchive this Resolution?
HDMI2.0 or 2*Dual link DVI can both realize this resolution,
28.what is a solution if the control pc is not near the sending card ? USB max lengh is 5m
you can use ethernet cable control or you can use an adapter to convert the usb to ethernt then back to usb
30.How can we receive certificate from the course and NCE ?
Sign in for at least 6 online NCE webinar and passed the final online exam
32.Theoretically you could use fiber instead of ethernet if you needed to go more than 100m, if you convert it on both ends, right?
YES, you can use fiber convert to do it. Like CVT320/310
