Last night I tried hooking my tv up to my computer to use as a second monitor I googled how to do it, Google told me to turn off the computer connect the hdmi cord and turn the computer back on so I did. But when I turned computer back on it said no signal on both my monitor and tv so I turned the computer off again and unplugged the hdmi cable from the computer to return to only using my monitor (which worked fine before I tried hooking tv up) but I just keep getting "no signal" on the monitor.
Everything I have tried
- unplugged power cord from computer and held power button for 1 minute then plugged power cord back in
- took out, ram, video card, and cmos cleaned all and still nothing.
- disconnected hard drive and disk drive
Everything listed above is what I was told to do on other sites, but nothing has worked.
Can you guys help me out? Thank you for your time.

Right click an empty area of the screen and select Screen Resolution. Is only one monitor showing. If you see both a tv and monitor then select your monitor. If you see nothing then click on the detect button.

 

Another thing you can try is to go to your monitor menu and do a reset back to default.

I was going to edit my post that you can't very well check screen resolution when you have no signal. I was hoping you could get a menu from the monitor. Do you have a vga or DVI cable to substitute instead of the HDMI cable? The monitor does have a VGA input, correct?

Do you have another graphics card to substitute. That is the only other idea I have at this point. From your first post, you reset CMOS using the motherboard jumper,correct?

If the problem still existed using the integrated graphics card then I would say the problem may be the motherboard itself. You don't see any Asus logo at boot, correct? According to the manual only the D-sub (VGA) port supports a display during post.

Go into BIOS and see if you need to enable your integrated graphics. What is the model number of the Acer? I believe you tap F2 to enter BIOS on an Acer.

Tapping F2 when you see the Acer logo with the VGA cable attached to the integrated card does not bring up the BIOS?
