The ViewSonic and Samsung you linked are LED-backlight TN panels. I generally recommend against LED backlights, since the blue tinge can actually make the monitors look worse than CCFL-backlit TN panels, despite being more expensive. RGB LED backlights are the exception, often outperforming CCFL backlights, but they're only available on professional level monitors which are usually VA or IPS anyway. A better TN model for price-comparison with the IPS models would be the Asus VH222H-P: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I have read several complaints about the build quality of this monitor from "monitor-philes" like myself such as a seemingly higher rate of dead or stuck pixels and backlight uniformity. However, "monitor-philes" (like audiophiles) are generally more critical about what may seem trivial to the average consumer.
i was reffering to the: ASUS ML239H Black 23 i posted the link above it cost roughly 229.00 plus tax.
so now iv narrowed it down to these if i go ips. would still love to know if the samsung such as this one http://www.newegg.com/Product/Prod [...] 6824001484 wich is not an ips if it is, just as good as a e-ips.
now iv excluded the one from bestbuy because its everwhere else alot cheaper.
im stuck between these 3 (if ips is the worth while move)
I would disregard the 21.5" LG monitor since for only $10 more you can get the larger 23" Asus monitor.
The remaining Asus and LG monitors both use the same exact e-IPS panel which is manufactured by LG Display. Therefore, the visual quality for both monitors should be nearly the same, unless either one or both have messed up firmware.
Between the two, the LG's design looks better to me. It only costs $10 more than the Asus as long as you use the given promo code by 4/6/2011. Plus it has a DVI port (the Asus doesn't) which I prefer to use over HDMI since I have separate speakers.
