    Connecting pc to tv


    Hello. I'm trying to use my tv as a monitor for my pc using HDMI but when I go to 'customize display' there is only one choice - "1". Another display isn't detected.

    I have HDMI 1 selected on my tv & the lead plugged in to HDMI 1. I'm using a Dell Optiplex 745 desktop

    Hope someone can help!

    Have you tried restarting with the cable plugged in and the TV powered on? I've had this issue using older computers with HDMI TVs before. If so, you could try unplugging your monitor to see if the TV becomes the primary display. Also make sure your resolution is at or below the max that the TV can handle.

    Do you have any other HDMI displays to test on?

    most of these problems are due to faulty cable, tried a new one?

    heavily suggest you try to borrow another cable - theres quite a differencies of the quality on making cables so brand news can be just dead.

    also, i checked the specs of your optiplex 745, theres no HDMI out per se, so do you have some external card that you use with that setup?

    also, check the back of your tv and make sure youre connected your HDMI to the port that says PC or PC/DVI for example. the more you support us with the devices by their specs the more we could help

    ok, thanks I'll try to borrow one, although I can't think of anybody who might have one

    There is actually a HDMI port. Most my pc the specs can be seen here: XPS 8900 specifications - General Hardware - Desktop - Dell Community

    The back of my TV has HDMI 1 & HDMI 2 plus a monitor input

    I've attached photos, although I'm not sure it's worked

    Thanks for your time & efforts
