Hey just wondering, if I was to connect my PC to my LCD TV via HDMI, would it automatically output without an OS, like a normal monitor? Or do I need to use the old cables rather than HDMI to have it output without an OS? You see when I build my new PC I'm thinking about not getting a monitor for now to save cash and use my TV instead but if I can't use my TV to install the OS then it will fail... Also if I can't connect to my TV with a HDMI cable to the install the OS, could I use the old cables? (IDE I think that's what they're called). Because despite my pc being quite new I think it has spots for the old cables like on PC monitors.
I think it's going to be hit and miss. If your system opts to output at a resolution your HDTV can display, you should be fine. My HDTV (Olevia 32" 232T) only accepts a few resolutions from my HTPC. Whenever I have to rebuild my HTPC, I always have to pull out my spare CRT monitor for the build and perform the following:
1) Build system with CRT Monitor connected via VGA D-Sub.
2) Connect the HDTV after the build as a secondary monitor.
3) Find a working resolution (720p).
4) Swap monitors in control panel to make the HDTV the primary monitor.
