My Experience: I have been using this TV as a monitor for my gaming setup and gotta say this thing is a absolute beast had it since 2010 and it has great color I have done photoshop on this, played CSGO great response time probably around 10 to 13 MS somewhere around there. Overall great panel it is better than the rest of the TV's in the house in terms of color reproduction and other stuff. Overall solid panel has never let me down. Id say my experience is very good.
Problems: Ok so I have encountered some od problems that may be because of how old this TV is. Firstly sometimes when switching HDMI connection or changing resolutions on the desktop when you go back to 1920x1080 there is color fringing around text but when you switch from HDMI 3 or whatever you are using than switching back to HDMI 3 the color fringe is gone and the picture is good again. Another issue is sometimes the panel will set all the settings to basically what VIVID is, what I do to fix this is to actually switch it to VIVID Than switching it back to manual and it fixes it. So far these are the only issues which may be due to age of the panel, also the tv says Signal is dvi connection on a HDMI signal which blatantly makes so sense but its probably due to age and it only shows on the BIOS screen when the PC is booting. like I said had it since 2010 but it has been a beast of a display and the fact I am using it as a giant computer monitor for competitive gaming really shows.
