    Hardware to WatchOut

    I'm going to throw a spanner in the works! Q1. Is such a set up suitable? The W7100 runs hot, so does the i7-4790K unless de-lidded. Moreover, 4U cases ex-factory have only 1 or 2 x 80cm fans at the rear oriented to extract hot air from the case. The 120cm fan(s) in front are oriented to draw in fresh air. This means, ex-factory, the case is setup for positive pressure. Depending on the operating environment (eg. location of air-conditioning) this may not be ideal, and negative pressure may be more suitable because a vacuum cannot exist, so fresh air is naturally drawn in providing there are vents for that...and most 19" cases are notable for absent vents unless the PCIe slot covers are removed or replaced with those that have have ventilation holes. Re the W7100, it draws air into its innards from a fan at its side, and extract the hot air out the top, back into the 4U case. IMO, a W8100 (or the latest AMD WX8200) with its 2-slot mounting where the hot air is extracted out of the case via rear vents would be more suitable for a 10-12 hour daily operation. Add to this the heat generated by an i7-4790K and the cooling system used (air? or AIO Water? - given specs do not say), and perhaps the 2 x 80cm fans at the rear are insufficient. There is likely turbulence inside the 4U and extracting the hot air generated by all components inside are not efficient. I would examine/test a negative pressure setup - 120cm fans extracting air out, 2 x80cm fans drawing air in assisted by natural ventilation (using PCIe slot covers with holes, or use more efficient 80cm fans.

    E2 EDID compatibility issue with AMD FirePro W7100

    AFAIK, F11 only applies for that particular bootup. I do not think the BIOS remembers your preference the next time you restart/reboot. Doing it the way I mentioned, the BIOS does remember the preference until you swap OS disk again.

    Display order on multi outputs single card

    That 'half a mind' would, IMO, be the best option, and use Watchout's Stage Display Outputs to reflect the changes, i.e. 1. Physically connect at the rear of the WX9100 from top down as 1,2,3,4,5,6 2. Order with Displays arrangement or Projectors to Screens from left to right as 1,2,3,4,5,6 3. Same with the naming of the Stage Displays. 4. In the Stage Displays OUTPUT, reassign 3 to 5, 4 to 6, 5 to 3, and 6 to 4. This saves unplugging and plugging, re-detecting, and confusion by staging personnel when on site. Thomas

    Display order on multi outputs single card

    " I’m on windows 10 with wx9100 +s400 sync. " Are you getting, for example, 1,2,3,4,5,6 with Windows and Radeon Pro, or 1,2,5,6,3,4 even though physical connections at the rear of the WX9100 are from top down 1,2,3,4,5,6?...and this occurs only when more than 4 display are connected. This is occurring with another display pc a client has, also with Win10 +WX9100+s400. We changed to Win7, and the anomaly remains.

    E2 EDID compatibility issue with AMD FirePro W7100

    Failure to boot from a cloned OS disk (resulting in a Windows installation error message) is likely because the original was installed under UEFI which results in Boot Manager governing the bootup. Putting in a cloned OS disk results in the BIOS listing the new disk as the top priority in the list of disks to boot from, and Boot Manager being demoted to a lower priority. To solve, after inserting cloned OS disk, boot into BIOS with F2 or DEL key. In BIOS, one should be able to click and drag Boot Manager as the first disk to boot from. F10 to save and exit, and Windows in the cloned disk should boot up as expected. You would have to do this everytime you change the OS disk. Hope that works for you, Thomas Leong

    8K render method

    Seems like no one has the experience you are asking for, including me. But I found this utility which may help, DXVA Checker, with features to check your graphics card which HAP will use - Features This program is a tool to check about DirectX Video Acceleration (DXVA), and it has the following features. Check Decoder Device and Processor Device supported by GPU Check DXVA decode performance and video processing performance Check DXVA API call in other applications by trace log Check DXVA mode supported by DirectShow decoder and Media Foundation decoder Change DXVA setting in some DirectShow decoders and Media Foundation decoders IMO, quad split 4K x 4k is probably easier on existing hardware i.e gpu and 'harddrive' capabilities. By 'harddrive' capabilities, I mean RAID multiple SSD or M.2, or bifurcated RAID M.2's on a PCIe3.0x16 add-on card like the ASUS Hyper M.2 x16 Card that could potentially give your over 10GB/s Sequential Read capabilities! Re your unanswered question on another post re M.2 being flash or SSD. M.2 is not really flash. Flash, used by RAM, loses its 'memory' on power loss. M.2, like a hard-drive, does not. But yes, it uses 'special flash type' chips on a small naked PCB board (common is 80mm in length), or integrated in a proprietary PCIe 3.0x4 housing with heat dissipation features inside. There are some M.2's that use the SATA 3.0 interface, so avoid those because you might as well get an SSD instead - cheaper. M.2 that does not use the SATA 3.0 interface overcomes the SATA 6Gbits/s limit by using the PCIe 2.0x2 or PCIe 3.0x4 interface (from 10Gbits/s to 32Gbits/s) . Some M.2 use the new NVM Express (NVMe) protocol (may need a driver install for older motherboards/BIOS) to take advantage of PCIe 3.0's high speed for parallel I/O operations. Some don't and just uses the PCIe 2.0 or 3.0 interface to connect via legacy AHCI with backward compatibility to legacy SATA devices and legacy older operating systems. Some M.2 connect to the cpu direct via the DMA interface. Some connect to the cpu via the motherboard's PCH chipset (X, Z, H or B series). The ones that connect via DMA direct to the cpu are faster but the ones connected via the PCH chipset are no mean performers either if nano-second differences mean anything to you. You will find almost all motherboards these days have at least the first M.2 onboard slot nearest to the cpu's LGA slot connected direct to the cpu via DMA with additional M.2 slots connected via the PCH chipset. Hope that helps! Thomas Leong

    Display Freezing

    Difficult to troubleshoot this. I would start with re-encoding the file to a lower bit-rate. If this works then try a higher one until you reach a point when it freezes again. This means the i7 cpu 6700K has reached its limit. Alternative may lie in the observation clues you made - 1. Pausing playback on the production computer jumps the display forward to the appropriate place in the timeline - playing again from there gives another 15-25 seconds of playback before freezing again; 2. The freezes seem to be correlated with a sudden spike in processor usage (up to %40 from a baseline of %10 or so) and hard-drive read (up to 40 MBps). Seems to be some caching going on here, and catching up when timeline is paused, and then continued from pause mode. Search for Zochri's post re tweaking the BIOS concerning disabling some speed shifting tech. Think they are: Disable CPU C State Support Disable C1E Support Disable BCLK Spread Spectrum Disable Package C State Support Disable Intel Speedshift Technology Basically you want the Display Pc's cpu to run at full 100% speed (whether baseline or factory Turbo mode) all the time. There is also a setting for this in your Hardware Power Options - default being 5%. You want it at 100%. Then monitor the Display PC as it plays for Thermal Throttling of the cpu and other clues. I use HWINFO64 version 5.30 onwards which allows one to monitor many parameters of another PC on the network. It seems like you are using the same or similar software to get the info you got. Good luck! Thomas Leong

    Watchpoint startup issue Windows 10

    With W10 Pro OEM version, stick with update 1607 (Anniversary Update). Watchpoint has startup problems with Update 1709. IMO, Update 1709 does not seem to have any additional advantage for multi-display use. Seems to be more for gaming, VR, netcentric apps, etc....things we do not use. Only anomaly I had with an ASUS X99WS i7-6850K workstation build with Win 10 Update 1607 and a Radeon Pro W9100 was when 5 or more displays are connected. No problems with 4 displays. The Display numbering with both Windows and Watchpoint would jump from 1,2,3,4,5,6 as connected top-down, becoming 1,2,5,6,3,4. Nothing that could not be solved with re-assigning Stage Displays in Watchpoint, but a hassle nonetheless. Can't recall the Radeon Pro driver numbers, but they were both the first Radon Pro driver and the first Radeon Pro Enterprise driver versions released after the WX9100 came to market. Thomas Leong

    Problems with 4k playback

    Additionally - 1. Win7 or Win10? 2. 4K is not possible even with dual-link DVI, so you must be connected to your Display monitor/projector via DP-HDMI Adapters or DP-DP. If DP-HDMI Adapters, are they HDMI 2.0 or 1.4? You need HDMI2.0 for 4K at 60.

    4х4K Capture

    In the first place, BEFORE you buy, you should clear up an anomaly with Datapath re their Datapath SC-HD4+. The specs say Ch 1 & 2 support 3840x2160 at 60Hz, but the pdf fact sheet in the description write up states two channels support 3840x2160 at 30Hz. In my own tests recently with a Philips UHD monitor, I could not get 60Hz with HDMI 1.4. Upped the DP-HDMI adapter to HDMI 2.0 and voila!...3840x2160 at 60Hz!!...and action video (a soccer match between Barcelona and Atletico Madrid obtained from the internet) was much much smoother.

    Datapath VisionLC-HD2 latency

    I know a Watchout 6.x user who has one HD2, and he has not complained about latency. Their company also has one of the VisionAV range, so they seem pretty happy with their Datapath products. Personally, I have the SDI version of the LC range and have not noticed any annoying latency. No software tweaking required to use it. Very important to know is your exact Motherboard model, your cpu model, and exactly which PCIe slots you have occupied with PCIe cards to determine if lane-sharing is affecting your Datapath performance.

    Error - Facility 34934

    Error Facility 34934: Usually occurs with Production PC, and is caused by using the Windows Std VGA graphics Adapter driver (seen in Device Manager>Display Adapters). Solution is to install and/or point Windows to use the 3rd party Graphics Adapter/driver, or if you are using the onboard graphics adapter (i.e. have a motherboard with the 'Intel HD Graphics Family' or 'Intel Basic Display Adapter' range of adapters/drivers), install this from the motherboard CD or from Intel's website. However, with this range of onboard Intel graphics adapters, Watchout itself may give a warning that some features may not display properly.

    Running 2x miid controllers

    Instead of MIDI, a DMX Lighting Controller outputting to an Artnet controller set to IN will give you more fader channels than you require.

    Experience with WX 9100 and S400

    "6 x 4K at 30Hz" using what output adapters? I found out that DP-HDMI 1.x will max out at 30Hz. One needs DP-HDMI 2.0 (or at a guess DP-DP) to get 4K at 60Hz. My tests were done with a single 4K monitor though, not more, and with the WX4100.

    Help with Windows 10 Watchout

    You can install Win 7 with the newest i7's. Basically, the problem is that Win 7 does not have the USB3.0 drivers auto-included in the installation process, so when the install asks for Drivers/harddisks, early in the process, insert the motherboard CD and negotiate to Drivers looking for USB3.0xHC or something like that (memory like my height!). It is one of those low down on a long list. Try each one. If after OK'ing, the install process gives you the next step, you are good to go. Else, it kicks you back to the list so you can try another. I've done it with a i7-7700 in Z270 motherboard before.
