    Hi,
    I'm going to build a computer and I'm going to use my TV as a monitor. Should I buy a motherboard with an HDMI port to install Windows or I have to connect the HDMI cable to the GPU HDMI port to install Windows?

    likely it should work with win 8 and 10
    and possibly with win 7 depending on vid card.. and bios setting of (IGP)Internal Graphics Port or PCI E if it has HDMI onboard.

    (you could also try with onboard first and no pcie then after install the pci e card)

    I've heard that tv's don't make for good monitors, they just do not have the same resolution and refresh rates, can you use your tv with an HDMI port for your pc with an HDMI port? yup....it should work

    I have a 50" Scepter dumb TV which I use as an extra monitor.
    ( Currently running the signal through an HDMI splitter, one to the TV and one of the 3 Dell 24" monitors hooked to this computer. )
    Essentially 1080p is equal to 1920x1080 which is what I am running it at. (True Color, 32-bit @ 60 Hz)
    True 1080p movies look beyond fantastic on it... 720p in full screen mode is clearer than Comcast cable reception here.
    :dunno:

    I mentioned that I've heard that from reviews of others. I've never personally attempted to run my pc through my tv, but I forgot to mention this is for gaming on a tv compared to a monitor, can't recall totally but it was something to do with the images in movement on the screen

    I'm going to play games on my PC and use my TV as a monitor, but it's okay. The only thing I have to do is to buy also a XBOX controller and set my TV on "Gaming mode" so I can enjoy gaming in Full HD at max 60FPS (my TV is a LG 42LN570S with Input lag=25ms on "Gaming mode"). Yeah, I know monitors will do better, but for now I'm not planning to buy a monitor (I have no money!).

    Totally depends on the TV you got. lower the ms number the better for gaming. Atleast for FPS games. Not so strict with rts games etc.

    Unfortunately it doesn't work. I just built my first PC ever, and if I connect the HDMI cable to the GPU or MB, my TV shows black screen. All cables are connected correctly to the motherboard and the fans are working (only GPU fans aren't working) but if I connect the HDMI cable to the MB it should show me the BIOS, right? I tried to connect a pendrive with ubuntu on it, but nothing happened (I think MB is damaged because the led of the pendrive didn't blink). I tried to connect the RJ45 cable to the PC and my modem shows a light on "Ethernet 1". I don't know what to do, could you please help me?

    Well my first concern would be those GPU fans... Did you already fry your GPU?

    The next question is did your have your TV's HDMI input set correctly ?
    ( I know, stupid question... But it HAS to be asked )

    No, I don't think so, because I have a XFX Radeon RX 470 RS 4GB and on the box is written the fans will activate only on determined temperature.

    Yes, I did. I even tried to connect to another TV, but unfortunately it didn't work aswell.

    Can you list your computer's components ( motherboard, RAM, etc. ) ?

    Sure:
    Motherboard: AsRock H110M-HDS
    Processor: Intel Core i5-6500
    RAM: Corsair Vengeance LPX DDR4 (2x8GB)
    Graphics card: XFX Radeon RX 470 RS 4GB
    HDD: Toshiba P300 1TB
    Case: SilentiumPC Regnum RG1
    Power supply: SeaSonic S12-450 (450W)

    What happens if I badly connect the case front panel wires to the motherboard? Because I think I messed up with POWER and RESET pins, but the PC turns on, so I don't know.

    Get a vga cable and connect that one so you can set your graphics options in bios properly. My sony tv doesn't work when my nvidia panel output color format is set to rgb. I need to select ycbcr to get an image. Maybe there is a similar setting in amd's config tool?

    @Joe C: I've also heard about problems with older TVs and VGA.
    Newer TVs should already be optimized for digital, so it shouldn't be a problem.

    Today I went to a computer technician, I'll let you know what is the problem. In my opinion it's the motherboard, but we'll see.

    If you use a T.V to game on a P.C will this strain the graphics card even more, curious as I would love to game on my 50" T.V

    That is exactly the set-up I also use. One problem though... Monitor and TV have different dimensions and so streams watched on TV sometimes appear in the wrong aspect ratio. Did you find a way to show live streams in VLC player, where this can easily be corrected, which it cannot in flashplayer...?
