I recently inherited an older PC running win7 and I wanted to see if it still works, the issue is I don't have an VGA monitor and VGA is all the computer supports, so at the moment, there is no way for me to see what is going on at the moment, so I was wondering if there is any software available that I can use on my android phone as a monitor via USB where I do not need to install any additional software on the older device. If anyone has any suggestions as to how I might be able to view the device's output, that would be brilliant. Thanks in advance.

    Unfortunately, I think the answer is “no” – unless you already have the necessary software installed on the PC. A Virtual Network Controller (VNC) would be ideal, and do exactly what you want, as would TeamViewer, but if it Is not already installed on the PC, I don’t see how you can do it without a display. Perhaps you can find an old, very cheap RGB monitor on eBay, CraigList, the “for free” listing in your local newspaper? Maybe there’s one lying in a cupboard somewhere at work? Perhaps a PC repair shop could help? ... -> – Mawg says reinstate Monica Nov 30 '18 at 7:22

    Yeah, It came with an older laptop as well, so i'd put linux on both of them and use them as a stack, but at the moment, this one has no way for me to see what I'm doing, assuming it still works at all. – Jacob Schneider Nov 30 '18 at 7:24

    When you power it on, do you see a power light? Do you hear a hard drive spin? If not, probably don't bother. If so, it's no guarantee, but maybe worth investigating? – Mawg says reinstate Monica Nov 30 '18 at 7:26

    The computer turns on, I hear the HDD and the fan and lights flash, so I assume it's not entirely broken. – Jacob Schneider Nov 30 '18 at 7:27

    If it really is RGB and you have a TV with SCART try using an RGB to Scart adapter. – Antony Nov 30 '18 at 7:42

It's VGA, not RGB - you'll need some flavour of software for remote access. You can't just plug a phone into a PC over USB and get it to do anything, let alone be a monitor by itself.

Now the solution you need is something that converts VGA to a HDMI or DP - these are commodity items with a bunch of options. You can then plug it into a modern monitor. Presumably you can then set up some remote access software to run it over wifi.

  • I have a USB keyboard and mouse, controlling it is not the issue, but I did consider an adapter-like device. – Jacob Schneider Nov 30 '18 at 7:29

    RGB monitors do exist. However, their input was VGA, so this is a problem that can be solved with the right adapter. Any monitor that supports VGA will work, depending on the connectors, your question makes no mention of the connector the computer uses. – Ramhound Nov 30 '18 at 7:30
  • Ah, I see. I'm not too great with the different port types... – Jacob Schneider Nov 30 '18 at 7:31

    VGA basically does RGB analog signals and a bit more. Bit of a shameless plug but this is a super useful post on hardware ID – Journeyman Geek Nov 30 '18 at 7:38
