Blu-Rays will likely look better on VA panel monitors than TN or IPS panel monitors. TN panels basically suck because they color shift is dramatic compared to VA or IPS panel monitors the more off center you are from the screen. But even if you set you head dead center there can still be some color shift. For example, my 24" Asus VK246H is a TN panel monitor I can make out color shifting simply by setting my head to stare at the center of the screen, and then roll my eyes to view the parts of the screen near the edge of the monitor.
VA panel are better than IPS panels for movies because they have higher static contrast ratios which generally range between 3,000:1 up to 5,000:1 for high end monitors. IPS generally manages to do 1,000:1. While TN panels may state static contrast ratio of 1,000:1, most are like 700:1 or 800:1. Static contrast ratio allows you to see the difference between subtle colors tone differences. IPS and VA panels can truly display 256 different shades of colors and truly display 16.7 million colors (e-IPS panels is an exception). On a VA panel monitor you might be able to tell the difference between GREY #170 and GREY #175. On an IPS panel you likely will not be able to tell the difference and on a TN panel you definitely will not see the difference.
Most monitors list Dynamic Contrast Ratio (DCR) rather than Static Contrast Ratio (SCR; which is the true measure of how well the monitor can display different color tones). DCR basically forces the monitor to change brightness and contrast based on what is being displayed. In a dark scene the monitor becomes brighter and contrast goes up, in bright scenes the brightness is toned down as well as the contrast. If find it extremely annoying and very misleading. So when you see a monitor advertised withe 20,000:1 or 5 million:1 DCR be wary or just ignore that figure because it does not mean anything.
The downside of VA panels is that they have slower response times than TN (as fast as 2ms), and IPS panels (as fast as 5ms). VA panel monitors typically have 8ms or slower response time. 8ms is still fast enough to play games, but hardcore gamers prefer lower response times. The problem is there are not very many VA monitors.
IPS monitors; especially the more expensive H-IPS, S-IPS and P-IPS monitors represents the best of both worlds. Good colors, very little color shifting until you get to extreme angles (same with VA Panels), and fast response times as low as 5ms. So they are good for both games and movies. The downside is price, they range from what most people would likely consider expensive $500+ to extremely expensive (easily $1000+). For the price that bought my 25.5" NEC LCD2690WUXi monitor, I could almost buy 7 Asus VH242H monitors.
The e-IPS panel is the less expensive version of IPS panels and you'll see them in many monitor that costs around $175 or more. They are like half TN panel and half "true" IPS panel. Color shifting is not as dramatic as TN panels, but not as consistent as IPS or VA panels. Response times are at best 5ms (like the other more expensive IPS panels), but no worse than 8ms. How's e-IPS's contrast? Don't know enough to make a general statement. Generally, better for movies than TN panels. While not as fast as 2ms response times, many gamers do not seem to make too much of a fuss about 5ms compared to 8ms response times. e-IPS panel monitors are also very inexpensive; able to compete with all but the cheapest TN panel monitors in terms of price.
