I think it's different in the older games.

TFC is so fast and people coming from all sorts of angles that i find the high fov really useful.

90 is like sniper zoom for me :D

LOL.

would you be able to tell from that pic if the middle monitor was pixelated? its not exactly a close up shot. everything seems to line up across the three monitors except for the alignment triangle which made me think that they are different resolutions.

maybe im out of my depth here but how could you line up a image across three monitors using different height and horizontal resolutions on each monitor?

im not sure what pixel pitch is so maybe that answers my question

If the image was spread across all three monitors at fixed resolution, this technology would be nothing new since Eyefinity does exactly that - it doesn't detect whether your middle monitor is 22" 1920x1080 or 27" 1920x1080.

If you decided to pair two 22" with a 27" it would work - but it would look terrible too. The middle screen would show the image scaled up to the screen's size and it wouldn't line up with the other monitors with much lower pixel density.

Solution? Allow for flexible resolution that isn't rectangular and find monitors with similar pixel pitch to create the image you can see in that picture.

Anything else you don't understand? :)

how similar would be similar enough 294 similar enough to 270 to look OK?

I think the difference in pixel denisty would be too noticeable in that case.

Someone with a 24" 1920x1200 prime display and two 23.6" 1920x1080 ones could be interested in this though.

Or 2x22" 1680x0160 and a 24" 1920x1080 which are quite popular these days.

thanks, I guess no harm in trying it once the drivers are out. I have

2 x 1280×1024 SXGA 1.31 5:4 19.0 294 86.3
and one 1920×1200 WUXGA 2.30 16:10 24.0 270 94.0 in the middle
 
I'm liking the idea of using 2x 1680x1050 with 1x 1920x1080 for eyefinity.
Good excuse to crack out the old monitors again :)
 
Why have they never managed to sort out mixed res with eyefinity ?. For example I have a pair of 20" @ 1600x1200 panels (one) each side of a 30" 2560x1600 but Eyefinity wont work like that and I cant afford to by 2 more 30" screens.

What is the limiting factor with it ? all 3 have a vertical res of 1600, I cant see what the problem is to be honest.

I have the same setup and i would like to know why as well.

i just about understand that lol, so when you say flexible resoulutions you mean resoulutions that arnt the norm or just normal resolutions but different ones?

I would expect power input to a graphics card to ~equal heat output. conservation of energy, where does the power input go? A tiny amount output from the DVI sockets, a small amount into the fan, the rest goes to heat I expect.

No it isn't. The classical cause of heat in a circuit arises from Johnson-Nyquist noise in resistive elements which, by the Fluctuation-Dissipation Theorem, gives rise to Joule Heating -- a thermal phenomenon which is proportional to the I^2·R power losses in the circuit. This is confined to resistive impedances. Reactive impedances do not dissipate electrical energy as heat. That is the classical phenomenon (though FDT is itself non-classical) but there are other quantum effects like phonons and quantum tunnelling which give rise to heat.

edit: A simple way to look at it is this: if all the electrical energy was being converted to heat, then your graphics card would be a very, very efficient electric heater and a very, very poor digital processor.

Personally I'm only interested int he 7770 mainstream part, hopefully it will give decent bump over my current 5770 and may even feature in my HTPC.
