Hello,
I hope you guys are doing well.
Quick question about my old but still up and running (thx to this forum, SSD in place of optical drive and graphics card cooking), mid 2010 iMac (high sierra installed).
I have a 14inch thinkpad that I would like to connect to it, also planning to buy HP zbook at back to school for kid who would also need to use iMac as external display from time to time (both with Windows11).
There was no thunderbolt port on imacs at this time, and obviously no on current PCs.
I shall use mini display port that is available but will it work as both counterparties are not Macs? I asked AI but not convinced about the process and probability of success. Did you guys tried the same experiment ?
I ve found minidisplayport to HDMI and to USBC cables. which one shall I buy ?
Thank you in advance.
 
Other way around. Whatever Thinkpad or HP zbook have for display out, you going to need (your display out)-to-mDP adapter.

To be clear:
Are you wanting to use the iMac as if it were a monitor? Can't do that without gutting the iMac and adding a display board.
Are you wanting to use some screen sharing software on the iMac which will connect via your home network to the Windows computers? There are numerous software solutions, but I am not clear if this is what you want.

I only want to use iMac as a passive, 27" display screen. I love how leight and easy to use my P14 is but screen is too small for excel for instance

For that purpose you will get away with third-party screen software using your existing network connection. I would use Jump https://jumpdesktop.com/ which is a paid app on the client (your iMac) with free connection software to run at the server end (your Windows devices). There are lots of alternatives - I don't have the experience to recommend particular software in your situation.

Edit: I have removed my comments doubting Target Display Mode and gutting the iMac

Just put it in Target Display Mode and plug it in as if it were a DisplayPort display

Many apologies to you and @Bigwaff where I was doubting this working with Windows. Target Display Mode should work with the OP's iMac using its Mini-Display Port.

As some recompense for my doubting, here are two references.
