How to Install Black Box KVM Switch - 4-Port
- Step 1 — Gather your cabling: Prepare a VGA video cable for each PC and the monitor, plus PS/2 keyboard and PS/2 mouse cables. If your keyboards or mice use USB, you’ll need adapters or a model that supports USB-to-PS/2 passthrough, depending on the exact switch configuration.
- Step 2 — Connect each computer: Connect the VGA video output from each PC to the corresponding KVM input ports. Attach the PS/2 keyboard and PS/2 mouse cables from each PC to the designated PS/2 ports on the switch. Keep cables neatly organized to reduce clutter on your desk.
- Step 3 — connect the display and peripherals: Attach the monitor’s VGA input to the KVM’s output port. Ensure the keyboard and mouse are firmly connected to the PS/2 ports on the switch. If a separate power supply is required by your model, connect it now.
- Step 4 — power on and test: Power on the switch (if applicable) and then boot the connected computers. Use the front-panel buttons or the configured hotkeys to switch between machines. Confirm that the monitor, keyboard, and mouse respond correctly for each connected PC.
- Step 5 — adjust as needed: If you encounter display or input issues, verify cable integrity, re-seat connections, and ensure the PCs’ video resolutions align with the monitor’s supported range. For best results, keep monitor and PC video settings within standard VGA ranges.

It works to divide a room, but it's not easy to use.
Color: Grey, Size: 6 Panel
This comes in multiple pieces and you have to build every single piece including the cloth that is between the two poles. There are plastic clips to hold the sections together, but they easily come off if you move the dividers the wrong way or try to reposition it. The only thing holding it up is rectangular shaped feet on the bottom and they are a pain when you hit it with your toes. It works if you need to divide a room, but its not pretty and there are far better options. It's cheaply made and has a habit of falling down if you are trying to use it in a straight or slightly angled line.

Nice divider. Set up is a bear. I am a bit concerned with stability. Overall I like it.

Great privacy room divider
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
I got this room divider for our game room that shares the garage/laundry room, to separate the spaces. I was happy that it was relatively easy to put together in less than an hour with nothing more than a screwdriver (provided) although I used a small handheld drill.
The instructions were pretty straightforward and easy to understand as everything was labeled.
I have 2 small grandkids at home running around while I put this together so my timeline to completion might be longer than others.
It recommends 2 people to assemble, but I was able to complete alone in about 40 minutes total and as I said I used a small handheld drill, (although it does come with a small Philips screwdriver) which is the only tool you need for assembly.
The first two panels took me about 20 minutes but the other 4 were simple repeats after the initial 2. After all 6 panels were assembled the plastic clips to piece them together were literally a "SNAP" to put on.
The poles are made of metal and the panels are made of a very sturdy almost canvas like fabric. When held up to the light not a lot shined through so very good for privacy.
You can snap them together in sections and have 2 separate panels of 3 or what ever configuration you want. They are easy to move and bend around furniture or other obstacles, also fold flat together if you need to put them aside for storage.
This worked out just as we had planned, very easy to move around when needed and I am very happy with this product. I loved how simple it was to put together, easy instructions, and the durability and functionality of it.

Decent for the price. Instructions suck but most people should be able to figure it out. More below.
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
SUMMARY:
3 stars from me because it's firmly average. It's fine for the price. Assembly and materials are alright but I can see some caveats depending on your circumstances. Assembly instructions do a subpar job of pointing out some details.
ASSEMBLY INSTRUCTIONS:
Maybe it's because I'm autistic and/or building model kits and assembling stuff is my jam, but I honestly thought people were exaggerating when they were complaining about the instructions and I'd be able to flex my ~superior assembly skills.~ I was wrong! These instructions genuinely suck, and whoever is responsible for making them should be ashamed.
The instructions do a poor job of calling out some details regarding orientation of parts, and some of the images do not actually match the physical parts.
For example, it does not really outline the assembly of the end panels clearly, and I can see someone accidentally using the wrong poles. I've drawn over a photo to show what you should do to try and make it clearer. Additionally, the manual shows a flathead screw for bolting the feet into position, but the actual screw is not a flathead. It also does not point out the counterbore, so if you aren't paying attention you may put the foot pads onto the wrong side of the foot. It's also missing the fact that you need to use another one of the plastic pieces when you finish assembling a panel.
ACTUAL ASSEMBLY & MATERIALS:
To their credit, all of my bags were clearly labeled. The assembly process wasn't difficult. It's mostly just tedious and requires a fair amount of space. I was able to assemble it by myself without any real difficulty. However, the way it's assembled means two things.
One, the fabric parts aren't removable without disassembly. So if you want to use this in an environment where they would require cleaning, I would seriously recommend looking for another option. Or, you could buy this just to use the frame pieces and then somehow buy or make your own fabric pieces designed to be removable with velcro or something.
Two, because of the materials I really don't have a lot of faith in this thing surviving disassembly and reassembly. Like a lot of sorta-cheap-but-convenient furniture, it uses those spring-button connections and plastic inserts with self-tapping screws. Those things are not really meant to be disassembled and rethreaded. It also relies a lot on the tension of the poles and the fabric to keep everything rigid and squared, which I think puts a lot of pressure on the aforementioned buttons, plastic inserts, and the hollow metal rods. So I feel like that will also cause issues with disassembly and reassembly.
Basically once this thing is assembled, it's not really meant to be disassembled. The best you can do is spot-clean the fabric if you need to.
Speaking of the fabric, I didn't see any labels on them or anything in the manual that says what they are, but they feel like some kind of polyester. They generate static electricity pretty easily, and pet hair and debris sticks easily. So that's another downside of them not being easily removable.
For the most part it does seem pretty stable. The poles seem to be pretty uniform in length so they're all making contact with my floor. Obviously this isn't structural so it shouldn't be supporting anything, but the two main feet seem to be doing fine with keeping this thing upright.
CLOSING THOUGHTS:
Really, it's fine for what it is, but it could be better in a lot of little ways and the substandard quality of the instructions just seems unprofessional to me, which is why I'm being so harsh with my rating. Depending on your needs and environment you may want to consider a different option. Preferably one that is made to be disassembled with better materials, and/or one with fabric pieces made to be removed easily.
