This review is from: Coboc HM-SW-4KUP-3X1A 3 in 1 out Amplified HDMI® Switcher w/ 4K*2K,3D HDCP 1080P and IR Remote, Extract Optical Toslink or Stereo Audio Output - Up-Scaling 1080P to UHD 4K at 24/25/30fps input.
Pros: worked with HDMI 2.0 cabled to deliver:
Cons: Auto select does not seem to work in my particular setup.
Other Thoughts: I am an EE and I do some audio and have done video work for churches setting up the video projectors, I have seen many HD cable issues, so I hope my lessons learned, the hard way, may help you.
I bought this specifically to have the bandwidth to support 1080P@120hz = 17.82Gbps, it did that with zero issues. This is an equivalent bandwidth for 4K@30 hz.
I don't have a way to test 4K @ 60hz, HDMI 2.0 is supposed to be two data channels each supporting 18Gbps. But I have no way of testing if this switch is using both channels with my setup.
Make sure you have output cables that support the highest input bandwidth or this switch will not appear to work. When it is not its fault.
Get at least two high bandwidth cables to troubleshoot each input, to make sure the signal is good before using long cables. Test the output cable first with the highest bandwidth input with a short high bandwidth cable. Now try any long input cables.
Longer runs can be a nightmare. I use switches like this so that only one long cable is needed to be run to the projector. If you run long cables over power cables make sure to cross them perpendicular and keep them 18" apart.
HDMI is packet based, just like the internet so a powered splitter can act like a switch for long runs if needed. I would never go over 50' even with an active cable.
If in doubt look for active cables as they "balance" the line to get the best signal possible.
This review is from: Coboc RM-18G-HDAC-10-BK 10 ft Black PET Jacket 36AWG Ultra Slim Stranded Tinned Copper High speed HDMI Active Cable w/ 18Gbps RedMere Technology,M-M - Ultra HD 4K x 2K & 3D Compatible - 4096x2160P
Pros: really thin and flexible
supports 1080P at 120hz
Cons: Not really cons but things to consider:
Display end is a little bigger than normal to accommodate redmere chip.
Really thin cable may be easily kniked
Other Thoughts: I am using this cable with a Nvidia GTX980M and a QNIX QX2710.
I bought this to connect my laptop to my 2K monitor that also supports 1080P@120Hz. This cable worked great, I have tried literally 10 other cables,3 of them being "4K" rated and only a 3' 4K cable worked to get the bandwidth out.
Picture is solid with no artifacts or jitter.
It worked immediately no issues, and the cable is really thin, so thin I would be careful not to kink it.
This review is from: QNIX QX2710 LED Evolution II Multi TRUE10 SE Monitor - 2560x1440 Overclockable
Pros: Great price
120hz thru both DVI and HDMI
Standard shipping was 2 day air from Korea
Cons: Stand construction poor
Stand design not VESA friendly
Requires disassembly to VESA mount and look right
VESA mounting screws too shallow.
Very flexible frame
driver hard find and to install
Other Thoughts: I have no issues with the screen itself, it is beautiful and also runs 1080P full screen. As long as I don't run into issues I would buy this again.
This was test was with a Sager P770ZM with a GTX 980M 8GB video card via both displayport to DVI-D and 4K HDMI output. Bandwidth issues with 4K rated cables at 6' but a 3' cable worked ok. New HDMI 2.0 cables on order.
The clear stand nub sticks out the bottom, I had to disassemble the stand to remove it in order to mount this on my monitor arm.
The frame is a little flimsy with a lot of flex this is not made to be handled a lot.
The standard thumb screws from my name brand monitor arm were too long, I had to use washers to male a good firm connection.
This monitor is definitely a modders dream, but if you are not comfortable working and "fixing" a brand new monitor steer clear from this. This is especially important for VESA mounting, as the stub does not come off. There is a good group of modding videos out there. I would recommend looking into them before purchasing this monitor.
