Need help with some LCD/LED basics and other queries

Ok first off....I can only get a TN panel...and have a budget ~180$-200$...and these only these options in that budget that I have available:

i. Dell ST2420L 24" Full HD Monitor with LED (1080p, 8,000,000:1 dynamic contrast ratio, 5ms response time):

ii. HP 2311f 23 inch LED Monitor (1080p, 3,000,000:1 dynamic contrast ratio, 2.5 ms response time):

iii. ASUS MS228H 21.5" LED (1080p,ASUS Smart Contrast Ration 10,000,000:1 (which I take to be dynamic contrast ratio), 2 ms response time):

iv. Samsung S23A300B 23" LED (1080p, 5,000,000:1 dynamic contrast ratio, 5ms response time):

v. Fujitsu Display SL23T-1 23" LED (1080p, 5,000,000:1 advanced contrast ratio (ACR), 3ms response time):

vi. AOC E2243FWS 21.5" LED (1080p, 50.000.000:1, 5ms):

Now, before choosing, I have a few questions abt LED/LCD panels in general:
1) the meaning of and the difference between the dynamic contrast ratio's of many LCD/LED (specifically the above)?...how do these values (which have a wide range for the above) have impact on visual quality?
2) they all have static contrast ratios of 1:1000...what do i make of that?
3) whether the difference in response time (2ms v 5ms) matters?

And which of the above would you recommend and why (from gaming + HD Movies) point of view.

Secondly, I currently have an E6400 2.13 Ghz + hd4850 setup and am looking to buy a 2500K. Now i can get a 560Ti/6950 2Gb, but i thnk i can also wait for Southern Islands release and get a GPU from that series in this range. In the meanwhile, I'll make ado with hd4850 with my new i5 2500K. Does that sound reasonable?

Thirdly, I have only 2 options for a PSU
1) Antec Earth Watts 750W (rated 0-50 Celcius operating temp)
http://store.antec.com/Product/power_supply-earthwatts/ea-750/0-761345-27750-1.aspx
2) Corsair GS 700W (rated at 40 Celcius temp)
http://www.corsair.com/power-supply-units/gaming-series/gs700w.html

Where I live, summer temps can easily go in the 45C range...now I was leaning in the favor of Antec PSU for this reason, even though i thnk Corsair is generally superior in the build quality (at least AX,HX and TX series are superv, not sure of GS but thats the one that i can get)....so among the two, which would you suggest?

Thanks!

No Samsung 2333T where you live? That panel should be in your price range and is a PVA panel. To answer your questions:

1. Dynamic contrast tries to dynamically adjust the backlight to (attempt to) increase the effective contrast ratio. Doesn't work very well IMHO.
2. Static contrast ratio is the true contrast ratio of the panel (i.e. with a fixed backlight intensity).
3. Monitor manufacturers distort their specs like crazy, so there honestly probably isn't too much difference between the 2ms and 5ms.

If you can really only choose one out of the monitors you listed, I would probably get the cheapest.

2nd, sounds good to me.

3rd, the Earthwatts is better, but 700W is massive overkill for the PC you are thinking of building. A good 520-550W unit would be fine.

hey thanks....abt the 2333T...that is available too..but a couple of questions:
1) 8ms response time listed on newegg....isn't that bad?
2) i like the 4000:1 contrast ratio (static), but the dynamic is way too less...again i hope that is not bad?
3) its not LED backlit...so is that OK? I mean are LED backlit panels better than LCDs or no?
4) no HDMI, i thnk?

1. Response time is the most exaggerated stat on LCD monitors. Are the TN panels faster? Yes. Will you notice a difference unless they're sitting side-by-side? No.
2. Sorry if I wasn't clear before. Dynamic contrast ratio is worthless, so you should ignore it.
3. First things first: all the panels you are looking at are LCDs. LED backlit just means that it is and LED backlit LCD. The main advantage of LED backlighting over traditional CCFL backlighting is power consumption and backlight longevity (no inverter). Not a big deal IMHO.
4. That is correct, DVI and VGA only. Remember that HDMI and DVI carry the same video signal though.
