As somebody who is not going to accept the transition of the PC Monitor market at the consumer level to a TN world I decided to experiment with getting the smallest 1080p HDTV I could at a reasonable price. I purchased this a Newegg. It is called the Scepre X32BV-FullHD. I bought this for use in my bedroom exclusively as a PC Monitor.
I've had personal experience with 2 TN Panel type monitors. A 22" model from LG with prominent backlight bleed on the top and bottom and a 27.5" model from Viewsonic that has moderate panel non uniformity around all the edges. They still look good with gamma adjustments but shadow detail is lost because of lower quality backlights. The actual 6 bit color reproduction looks good but is is the backlights that really are subpar. The LG model has also an annoying dynamic contrast feature that constantly adjusts the brightness to maximize apparent contrast. All it really does is drive you crazy because you see the light shifts as they occur. What a joke.
Anyhow, a lot of TN panels in 24" sizes are approaching the $500 mark so for $600 I decided to go for a 32" 1080p HDTV that has none other than an 8 bit panel!!! What does that mean? It means true color representation of over 16 million colors and a backlight that is much more uniform than an TN panel ever will be. The viewing angle is 178 degrees * 178 degrees compared to the usual 160 * 160 of a TN. When you game in a totally dark room you can't have too much light bleed or light blotches/panel non uniformity because it will distract from the viewing experience.
The Sceptre is a very good PC Monitor. The 16:9 aspect ratio does take a little getting used to after using 16:10 PC Monitors but the shadow detail is much better than any TN and probably average for an 8 bit IPS/MVA/PVA monitor. For $600 you are not going to be getting quad XGA quality like the HP LP3065 but you will get one awesome, huge gaming experience.
In going the HDTV route there are some things to consider. I'm not having any issues with the Sceptres 6ms response time. Frankly I don't care about response time because I've never really noticed any lag in any of the monitors I've ever had.
What is the color gamut? That is a feature that certain monitor manufacturers like to tout in the PC market but I've never seen in the HDTV arena. I have no clue what it is on the Sceptre but higher values are important for more vibrant colors. The color looks good after I up the saturation with my videocard via the VGA connection. I have not tried the HDMI connection yet.
Contrast Ratio? Sceptre claims 2500:1 ratio but it really does not look to be any better than 8 bit PC monitors I've seen at 1000:1.
In short, TN panels suck compared to good 8 bit panels of similar price. Stay away from TN if quality is a concern at all.
