W13 Projector bought from amazon
These are awesome for backyard partys. Put a full size sheet up on your greenhouse front or garage door and project tv or youtubes to watch in the yard. Back yard drive in. I used my thinkpad T480s laptop and a JBL Charge 5 bluetooth speaker to make the magic happen. Another item that made setup less painful is a tripod. Attach your projector to a camera tripod for easier setup.
Trying to attach thinkpad to a projector I bought from amazon. properties in display say display 1
I followed instructions in step 1 and was watching tv soon.

When Windows only shows Display 1, it means your ThinkPad is completely unaware that a hardware connection has been made to your projector. Because it is failing to detect the secondary hardware, the standard display options won't work until a physical or electronic handshake takes place. [1, 2, 3]
Follow these progressive troubleshooting steps to establish the connection:
1. Force the Hardware Handshake <-- this got mine working
Laptops and projectors occasionally fail to establish an initial handshake if they are connected while both are already running. [1, 2]
Unplug the HDMI or USB-C cable from both your ThinkPad and the projector.
Turn off your projector completely.
Keep your ThinkPad powered on, then plug the cable firmly back into the projector and the laptop.
2. Match the Input Source
Many modern projectors bought on Amazon have multiple inputs (HDMI 1, HDMI 2, USB-C, AV) and do not automatically switch channels. [1]
Locate the Source or Input button on your projector's physical chassis or remote control.
Manually cycle through until it matches the specific port you plugged your ThinkPad's cable into. [1, 2]
3. Change the Display Mode
Windows might have the projection settings restricted to the internal monitor only. [1, 2]
Press the Windows Logo Key + P simultaneously on your keyboard.
A quick menu will slide out on the right. Select Duplicate or Extend. If it was previously stuck on "PC screen only", this forces Windows to search for the output port connection. [1, 2, 3, 4]
4. Use "Detect" in Settings
If you are still only seeing Display 1:
Right-click an empty space on your desktop and select Display settings.
Under the multi-display arrangement diagram, look for the Multiple displays dropdown section.
Click the Detect button to force Windows to scan the hardware ports for an unacknowledged device. [1, 2, 3, 4, 5]
5. Check Adapter and Resolution Limits
USB-C Adapters: If you are using a USB-C to HDMI adapter or a mini-dock, ensure the ThinkPad port you are using supports Alt-Mode Video Output. Some ports on the side of a ThinkPad are strictly meant for data or charging. Try an alternative port if one is available. [1, 2]
Resolution Bottlenecks: Budget Amazon projectors usually cap out at a native resolution of 1080p (1920x1080). If your ThinkPad has a high-resolution 2K or 4K panel, it might be pushing a signal the projector is physically rejecting. Try lowering your Windows display resolution to 1920x1080 temporarily to see if a link is established. [1, 2, 3, 4, 5, 6]
If the projector screen still reads "No Signal" after these steps, please let me know:
Are you using a direct HDMI cable, or are you adapting it through USB-C or a docking station?
What is the brand or model of the Amazon projector?
Digital Halloween Illusions with a Backyard Projector
If you have a budget projector like the W13 and a solid Bluetooth speaker like the JBL Charge 5, you have the perfect setup for creating high-tech Halloween illusions. Here are a few ways to transform your yard for trick-or-treaters:
Window Apparitions: Hang a thin white sheet or frosted shower curtain inside a front-facing window. Project looping videos of wandering ghosts or zombie silhouettes from inside the house so they are visible from the street.
Singing Pumpkins: Set up three uncarved pumpkins on the porch. You can map a video of animated, singing faces directly onto the pumpkins, using your Bluetooth speaker to play the accompanying music and sound effects.
Garage Door Portal: Put a full-size sheet up on your greenhouse front or garage door to display a massive, looping video of a creepy dungeon, a zombie containment zone, or giant spiders swarming the driveway.
Floating Holograms: Hang dark, semi-transparent mesh (like mosquito netting or tulle) between two trees in the yard. Projecting an animation onto the mesh in the dark makes the fabric invisible, creating a free-floating 3D ghost effect.
You can easily build custom projection loops for these setups by layering eerie soundscapes in Audacity and mixing visual effects with OBS Studio before running the final file off your laptop—I use my ThinkPad T480s to make the magic happen. Whether you are aiming for a family-friendly spooky vibe or want to genuinely terrify the neighborhood, a simple projector setup is a great way to step up your decorating game.
