| Q1 | difference between 4k screen and mosaic 4k screen | 4K source to display on 4K screen has better display effect. Smaller source like Full HD to display on 4K screen needs to enabl scale and mosaic, which reduce display effect. |
| Q2 | why screen lagging when we make 4k through mosaic mode | Possible reansons: 1. VIdeo source is not sync, so screen is lagging. 2. Different controller models loading a screen. 3. DIfferent controller firmware versions. |
| Q3 | why we use DVI single link and dual link | Because single link and dual link have different max video source resolution. To have a better video quality on a big screen, we should use a bigger source. |
| Q4 | If we use 4 vx4s for 4K screen does it mean that we can use maximum 1080p resolution scaled to 4K | Yes |
| Q5 | will DVI source handle 4K resolution. That case what is DP port means? | Max DVI source is dual link DVI which support 3840x1080 @60Hz max, but 4K resolution is 3840x2160Question. DP 1.2 supports 3840x2160 @60Hz |
| Q6 | can ethernet cable used to cascade the controllers instead of USB cable | Different controllers requires different cable for cascading. MCTRL660 support ethernet cable for cascading. But MCTRL4K supports usb cable only. For more info, please refer to "Redundancy Configuration" NCE training on 12th May. |
| Q7 | do you get the correct regulation. video quality will not go bad when we do mosaic | If the source is smaller than LED screen resolution, there is video quality loss for sure. |
| Q8 | Does VX6s can support 1536*1792 input resolution | No, 1536x1792@60hz is bigger than 1920x1200@60Hz which is max input resolution for VX6s. |
| Q9 | could you explain more explicit about 4K output vs output of MCTRL660 | MCTRL 4K has larger video input which is 4K resolution, and MCTRL 660 support max Full HD input. From the usablity, MCTRL 4K is easier since MCTRL660 solution requires a splicer. From the video quality, MCTRL 4K doesn't require scale so it has a better display quality. |
| Q10 | What about treatment time between a MCTRL660 and VX4S? If the VX4s is processing, how many frames does it take to do it | When VX4s enables video processing function like scale or mosaic, there will be 1 more frame delay than on MCTRL660 |
| Q11 | Is there a NovaPRO UHD Sr= NovaPRO UHD | Yes, it's NovaPro UHD |
| Q12 | How to do backup with MCTRL 4K controllers? Meaning 1 controller is main, and the second one is backup., and when I unplug signa from the first one, is it possible to do the switch seamless and without noticing any delay? | Please refer to "Redundancy Configuration" training on 12th May |
| Q13 | 8k video source available in processor? | No, not yet. COEX system will support 8K. |
| Q14 | How can we give different content on screen like 3 parts or 4 parts | It requires more layers. VX4s supports PIP which is 2 layers. VX6s and Pro UHD Jr supports 3 layers and Pro UHD supports 6 layers. You can configure the layers position as you want on the screen. |
| Q15 | When use some VX6S and set LOOP, Do we have to set with Controller? | No, connecting DVI cable is OK to get the signal. |
| Q16 | can the ProHD support 2048x640 resolution on HDMI instead of DVI? | Yes. |
| Q17 | if you do a mosaic you don't need a main processor?for example 3 output..you need 3 processor for that and 1 for main processor? | No, you don't. Because each one of the 4 processor are same to load a part of the screen. And each of them has the same video signal from the DVI Loop. The VX4s only needs to capture the part itself and scale up to it's LED loading area seperately. |
| Q18 | 8k why not ? mctrl4k can do it 8k*1k also J6... | 8Kx1K is not 8K, because 8K is 8K x 4K which is 4 times 4K x 2K. 8Kx1K is still 4K. |
| Q19 | Can we use Pro UHD JR link with 4K by using Fibre Optic port | MCTRL 4K can be the controller only but Pro UHD Jr can be set to work as controller or fiber converter. So It's possible to use MCTRL 4K to work as controller, and set Pro UHD Jr as fiber converter via fibers. |
| Q20 | do the Mosaic screens need to be the same size or can they be different sizes | They can be different sizes. If they are same, you need to chose "EQUAL" in the mosaic setting in the front panel. If they are different, you need to chose " UNEQUAL" in the mosaic settings in the front panel, and set the loading area for each VX4s one by one. |
| Q21 | can Ihave the comparison of 2x pro UHD jr and mctrl4k with cvt4k? | 1. Pro UHD Jr is All-In-One controller but MCTRL 4K is independent controller. 2. 2 x Pro UHD Jr has more flexibility because they can be used as 2 controllers in the next project, MCTRL4K only 1controller. 3. 2 x Pro UHD Jr is more expensive. |

| Q1 | what will be the effect on the images or video we are projecting on the screen if we use the 4k Led Processor and then our screen pixel size is less than the 4k pixel like 1920px x 1080px? is there any difference or what is the possible outcome? | No difference. You only need 4 ports of MCTRL4K and the screen will display a FHD part of the 4K video source. There is no scale and will be pixel to pixel dispaly. |
| Q2 | what can provoques delay in the image between each controller ?? | There is no delay among the controllers. |
| Q3 | 4k splicer aka DVI DA? Or other signal DA? | 4K splicer is not DVI DA. 4K splicer is to split a 4K source into 4 separete Full HD sources to feed 4 MCTRL660 controllers. |
| Q4 | is it possible to create 4k with 4x660s without the splicer? using starting co ordinates? | No, beacause the max input source that 660 can get is a 1920x1200 source. But 660 is not capable to make scale or mosaic, so the max coordinate is within 1920x1200, but not a 4K resolution. |
| Q5 | Can we toggle between two input like DVI and SDI in a cascaded way while using VX4s in image mosaic mode? | Yes, but the 4 VX4ses needs to use either DVI or SDI signal. So you need to chose the same signal on each of them, but the mosaic setting is same. |
| Q6 | the 1080p to splice 4K. This is a upscaled 4K (Fake 4K)? | Yes, it's not real 4K, it's upscaled. |
| Q7 | why do we split it into 4 screens | Because the MCTRL 660 and VX4s max output is 19200x1200, however the screen is 3840x2160,so we need 4 controllers and that's why we need split it into 4 screens. |
| Q8 | What is the maximum pixel count that can be inputted on the VX4S | 1920x1200 @60Hz. |
| Q9 | can we do image mosaic settings in the software or just on front panel | You can do it on SmartLCT and front panel. |
| Q10 | Can we do a 4k project with a 4K video splicer with 4 4X4s for the same screen size | Yes, you can disable the VX4s scale and mosaic function, and the VX4s will work just like MCTRL660. |
| Q11 | Using 1 x j6 to 2 x Mctrl4K, do you achieve pixel to pixel resolution | No, because J6 can accept the input video source up to 4Kx1K @60Hz, it's scaled up to output 4Kx2K. |
| Q12 | why need connect one 4k to processor and another 4k to controller ?? | It's 4K source input to processor and the processor will output 4K source to controller with mutiple layers. |
| Q13 | For redundancy would it be best to use two UHDjr when using any? Isn't it true that If I use one UHDjr, I must use a second for true redundancy in case the either fails | Yes, if one UHD Jr fails, the other will take over automatically. |
| Q14 | R5 retation function with which receiving card? | A8S & A10S Plus |
| Q15 | can the MCTRL660 do image mosaic 4k the same as vx4s | No, because MCTRL660 is independent controller not all-in-one. |
| Q16 | How do you manage video tearing between separate Sending cards | Possible reansons: 1. VIdeo source is not sync, so screen is lagging. 2. Different controller models loading a screen. 3. DIfferent controller firmware versions. |
| Q17 | you said at 1080p level it is pixel to pixel but this can’t be correct if LED screen is 4k and input is only 1080p | Yes, you're right. It requires a 4K source and split it into 4x FHD source which feed the MCTRL660s or VX4ses. |
| Q18 | according to the manual with the mctrl660 the ingest resolution is not 4k compatible and neither is the output resolution, what I understand is that they are only used in mosaic? or what is the way | Yes, it works in mosaic. We must use a splicer to split 4K source into 4 FHD sources. |
| Q19 | How can we use MCTRL 600 and VX4s together for a larger resolution screen ? | It's not recommended to use different types of controllers in a large screen. Because they process in different ways which may cause image delay in the screen. |
| Q20 | Will the scaler in the vx4s scale a 1920x1080 signal up to 3840x2160? | No, it can't. Each VX4s captuers 1/4 of the FHD source and then scale up to FHD on screen. So each VX4s will upscale 1/4 FHD to FHD so there will be 4x VX4ses to output 4 FHD for 4K screen. |
