The Acer H5360 is also called emachines V700 (afaik emachines is a subsidiary of acer). It's exactly the same pj, just 100€ cheaper. For nvidea 3D the inf file needs to be changed ( to the acer H5360 inf file). So I'm about to get the V700.
Now to the above mentioned problems of 'older' models of the H5360 with eco mode and upside down. The emachines V700 already has the new firmware, so that's another reason to get the emachines V700.
-the upside down problem is a bug in the old acer firmware. It can be resolved by switching off auto detect and setting it to upside down manually.
-the eco mode problem also is a bug in the old acer firmware. The problem with the newer acer pjs is, that you can't just update the firmware yourself. It needs to be send to acer and they'll update it for you. It shouldn't cost you a dime, as long as you still got warranty (afaik 1 year in the US, in the EU 2 years warranty). Use this website to get the firmware updated (if you are in the US)http://secure2.tx.acer.com/FixMyAcer3/FixMyAcer.aspx
IMHO it's a bit strange that Acer/emachines won't let their customers update the firmware themselves. Maybe to many 'DAUs' around or just new method to generate aftersales revenue...
