I had something like this with a tower computer. I couldn't tell if it was the graphics card or the motherboard. I ended up dumping the computer. I saved the graphics card, but need to test it in another computer. I am guessing it is not loading because you may have switched it off at some point because of the checked green screen and may have damaged the operating system. Firstly, can you change the graphics card for another to see if this gets rid of the checked green screen. If this works, it won't adress it not loading, but could get rid of the checked green screen which is the first problem to deal with.
try to reinstall the video driver for your computer ..download the driver from the support site and run it into computer for to install ..When you finish ..restart the computer ..plug the hdmi ..and enable teh secondary monitor ..from eh video settings ..(control panel ) or in the tray (active programs ) ..Basically you have to open teh video settings ..and select in the list teh display settings ..and enable the secondary monitor and choose a function for it ..(in your case clone will be best ) if you choose extend..it will extend your monitor with the tv ..and it will not be the thing you need for viewing movies ..This way you will have same image in the tv as in the monitor .. I thing it should have a key for doing this auto ..but Im not sure..usually on laptops the function is by pressing Fn and the key with the monitor on ..(F4 ; F5 or F7 ) ..but I suggest to do it from the settings ..and will work .. have a nice day .and good luck .. By the way ..it may not be needed a reinstalling of the graphic card ..if it works ..so you can try to enable the monitor right the way ..but if it don't work it means its damaged and need to be reinstalled ..

It is best to test your monitor on another computer. If it does not work on another then the Monitor is definitely the source of the problem. If your monitor works on another then the problem could be your video card or that your resolution is beyond the capability of your monitor. To test this, when you restart the computer if you do not see the BIOS screen or even the windows logo screen then it is the video card, but if you do and this problem occurs when you are in windows then your screen resolution is the problem. You could also try using a different monitor on your computer to check those settings.
Try another monitor on your computer. If you get video with another monitor then you know that your original monitor is bad. If you don't get video with another monitor then you know its something with the computer.
If the computer is the problem. Try reseating the memory and CPU. and also make sure the computer has no dust or dirt in it. If you still can't get no video then the motherboard is bad and would need to be replaced.
You're probably lucky that this happened now. You're most likely still covered under warranty. Contact Acer support and arrange a swap. If your pc works okay with another monitor there's no point in troubleshooting further. Get that monitor switched before the warranty runs out.
check the website for drivers. But it seems to me that there is another problem most computer boot up no matter what screen is hook up. have you tried any other monitors ? If you have and the work im not sure what your issue is but i would say that most likely if another monitor works that it is the monitor but if none of them work it is a graphic card issue. If you could let me know what you are running and i can help more i.e what window's and what type of graphics card you are using
There must be a connection problem from monitor to pc, check the pins to see if any are bent in the plug to the pc.
If it is a seperate graphics card, check that it is seated correctly in the agp (brown) slot and not come loose.
Try booting in safe mode (F8) on boot and select boot Windows in safe mode(this will run pc with normal vga driver and not the graphics driver), and see if it stays on, if it does it is a graphics card driver fault, so re install.
