Acer aspire external monitor not responding.

I opened up acer icon for projector i think by mistake, when i closed icon on taskbar, external monitor no longer responds, my laptop screen was broken hence the external monitor, but now when i power off/on i cant get display on external monitor, i've tried toggle switch fn + f5/f6 ? I've tried connecting to tv which used to work as monitor also, but not now, is there a simple keyboard function to revert as it is only since i opened that acer icon on desktop ??

Re: acer aspire external monitor not responding.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

I am using a MacBook with an Acer Monitor with a mini connection. The monitor shows the start up screen of the MAC but known of the icons nor does it reflect what is on the MacBook while I am working.

This is a very simple solution, fortunately. The default behavior of an external monitor connected to a portable Mac is to act as extra space, effectively extra screen "real estate," where you can move windows or do whatever else you need to.
Verify this by moving your mouse to the right-hand side of your screen, and then keep going - you'll see your mouse appear on the external monitor.

If you want to have the external monitor reflect exactly what you are doing on the primary monitor, simply go to Apple menu > system preferences > displays > arrangement and check 'mirror displays.'

And that's all there is to it!

Hello, I have an Acer Aspire 1356LMi laptop. It

This problem is mostly likely with your LCD screen. It needs to be replaced. I suggest you connect your laptop to an external computer monitor and see if you still see the same issue on the external monitor. If you don't see it, then for sure it is not your motherboard or graphic chip. It has to do with your screen. In rare cases this can also happen if your wiring for the LCD screen is going bad or damaged.

Once you connect the external computer monitor to your laptop, turn your laptop on and located the "FN" and "F4 or F5 key depending on the laptop model" key on your laptop. Hold FN down and hit the F4 key once and see if the screen switches to your external monitor. If not, hit it again and wait.

Some newer laptops auto detect external monitors when they are connected to one.

I want to use a NEC Multisync 1700V monitor as an external display for my Thinkpad T400. However I get no image when I hook up the laptop and change the display scheme to display on my laptop screen +...

The only I can think of is the resolution setting that your T400 is putting out that your NEC does not like andcannot display, look at the T42 resolution when the NEC is hooked up to it and try to set it to be the same in the T400.

Icons and everything displayed sideways

If you're referring to the taskbar that's usually on the bottom of the desktop, click on the taskbar and drag it to the bottom. Then right click on the taskbar and check "Lock the taskbar". This should solve your problem. All the best.
