There are several differences between the PZ80u and PZ85u:
- The stated native contrast ration of the PZ80u is 20,000:1. vs 30,000:1 for the PZ85u.
- The PZ85U includes a PC (Mini D-sub 15-pin) input while the PZ80U does not.
- The 3rd set of additional inputs (a 3rd HDMI, S-video in, component video in and audio L/R in) is located in the front of the PZ80u as opposed to the side on the PZ85u.
- Because of the different locations of the additional inputs between the PZ80u and the PZ85u, and different locations of the internal speakers, the two units have different bezels.
A word about contrast ratios: While Panasonic states there is adifference between the PZ80u and the PZ85u many people claim there is no discernable difference between the two sets. Many here at the AVS forums attribute the difference in stated native contrast ratio to the C.A.T.S (Adjusts the brightness and gradation accordingly to optimize contrast) video-processing feature on the PZ85u. The consensus of professional calibrators who have calibrated a PZ85u recommend turning this feature off.
UPDATE: Confirmed, the 85u is Native 30,000:1 with CATS turned off, see confirmation info
here.
The PC input does not display at the native resolution of the TV. Because of this, many people choose to run their computer through a HDMI port in order to display at the native resolution of the TV. If you can live with a stretched out image, than the PC input may be enough for you. However, if you plan on watching HD content from your computer to you PZ85u, you will need to use an HDMI from computer to TV in order for the video to display at the native resolution of the TV.2. Should I concern myself with a break-in process for this TV?
Panasonics official break-in info can be found

A more model specific regimen gleaned from this website follows:
First 100 hrs.: Service Menu Time Counter instructions
here.
Break-in DVD/SD card 24hr/day when your not watching TV, this makes the 100 hrs go by much quicker (get it
here). Using the SD version saves wear on your DVD player. Make sure to set the picture viewer to slide show with no time limit. Be sure to turn off No Signal Shut Off and No Action Shut Off under the advanced Set-Up menu if you are going to run the slide show.
Viewing:
Aspect: Just or Zoom (no bars)
Games: Keep it to a minimum (no 2+hours of same game, HUD, etc)
TV: Mix up your viewing to avoid long periods on the same channel with tickers or station logos
Don't leave anything Paused for extended periods (15 minutes is a good rule). Same with static images (DVR menu, etc.)
A word about bars: "Burn-in," and/or image retention (see below), is an uneven aging of the phosphors in a display device. Such uneven aging happens when bright, static images are left onscreen for an extended period of time, which can leave a visible "shadow" effect. In the context of bars, either vertical bars (4:3 content) or horizontal bars (typically any widescreen content of a ratio greater than 1.85:1), the lack of content in the bars area exempts these phosphors from being aged at the same rate as the phosphors in use. The general consensus is to avoid any bars during the initial break in period, i.e. the Just or Zoom modes recommended above. After this period however the consensus gets a bit less defined. The rule I follow, as do some others I believe, is simple, I watch pretty much all 4:3 content, even HD feeds, in Just mode, simply for the fact that most 4:3 content isn't typically critical or reference level material (there are of course exceptions to this, particularly many of the pre-Cinemascope classics) . I watch all widescreen content (1.78:1, 1.85:1, 2.20:1, etc) in FULL mode with bars, this includes both HD & SD content. I've yet to experience any IR.

*The C.A.T.S feature in only available on the PZ85u
**A word about size 1 vs 2: This is only a concern with HD channels. Most OTA HD channels do not utilize full 100% pixel and therefore have color bars running vertically, usually on the left side (these bars can be pronounced or little more than a thin line). For this reason these TVs have the size 1 option which is very slightly "zoomed" in, it's about 97% of the image and gets rid of those annoying bars. When gaming and watching blu rays/HD DVDs one should always utilize the full pixel size 2 option for maximum resolution potential.
3. Is there a recommended setting for my PZ80/85u after break-in? How can I go about optimizing my settings? The simple, short, and easy solution is to use the recommended settings in the “
Panasonic PZ80/PZ85 Calibration Thread (Updated first post)” thread. There you will find a series of recommended settings that members use on their PZ80/85u’s. At the time of this writing, the recommended settings are as follows.

These settings were “calibrated” using a DIY DVD. Calibration is the process of adjusting a picture to comply with standards used in DVD and HDTV production. There are several calibration DVDs available on the market, each one having their own pros and cons. These DVDs offer an inexpensive and (relatively) easy way to improve the picture of your television.
You can also hire a professional calibrator to come to your house and professionally calibrate your television. These technicians use several tools to more accurately calibrate the picture of the TV.
For more information on calibration, please visit the “
Display calibration” area here at AVSForums.
4. Should I worry about image retention or burn-in with this TV? After the break-in period, there is very little reason to worry about image retention or burn-in (IR/BI) on the PZ80/85u’s. With the advancement of plasma display technology, there is less cause for concern in regards to permanent (even temporary) damage to the screen. The following is a brief and concise description of image retention and burn-in.
IR (Image Retention): You may see some of this, especially in the first few hundred hours if you don't follow the rules (or even if you do follow the rules!). It is not permanent and quite reversible, simply run the white screen or a full screen show for a while.
Burn-In: NOT the same as IR. Permanent. Increasingly harder to produce as Plasma technology improves. Not really a concern unless you really abuse the set.
