I like to use my ASUS monitor for my modern consoles like my Wii U to reduce input lag.

As for older consoles, I'll use either a very small HDTV or a CRT.

39" Sony. It's 1080p but I'll be upgrading to 4k later this year.

Older 52 inch Sharp Aquos 1080p LCD for current consoles. Love this tv.

17inch Sharp Aquos 720p LCD for older/retro gaming.

47" LG, I'll have to go back and look at the model. It's got a pretty sharp picture, and I don't notice any blurring from my Wii U gaming.

A Sony Bravia 40". Bought it back in December 2009. I also use that 24" PS3 monitor that I bought for $99 on Boxing Day 2012. They do the job as I don't care about how the games look.

Panasonic TC-P50X60, 50" 720p plasma, and its got better picture quality than most LCD / LED 1080p sets. Plasmas FTW!

I wish I had picked up one of the 1080p S-class plasmas in 2013 before Panasonic retired them. Now only Samsung and LG still make plasmas but they aren't as good as Panasonic's were (or the legendary Pioneer Kuro series), and they are both set to retire them soon as well.

Sony XBR-52HX909, does a great job, but still really lacking compared to my old Sony KDS-50A2000 SXRD. The death of DLP and SXRD is still a massive loss to me. Although the 22ms response time is not bad, it is definitely noticable comming from a 5ms response. But, at least it is not as atrocious as some of the Samsung and Vizios I have used at other peoples houses.

I have been looking at upgrading to the XBR-65X950B, but may go with next years model depending on a number of things. Really, looking at Sony and MS to stop this stupid little game, and unlock 4K on these more than capable systems, there is no reason for XBL and PSN not offering 4K movies.

46in Sharp Aquos Quattron LED TV

I have a 1080p Samsung Plasma TV (Can't remember the model). I specifically chose this for gaming, as plasma's have much less latency compared to the more common LCD displays, but isn't as expensive as OLED. (Plasma actually costs less than LCD now)

Works great, except some of the HUD from games I play a lot are actually burned in very slightly (Not noticeable unless the screen is blank, and you look hard for it). Also, it makes a slight buzzing noise at times. Turns out that's a side-effect of low air pressure (I live in Denver Colorado, about 5,300 feet above sea level)

32" TCL, 1080p.
Seems to work well.
