_______THE AE700 TWEAK LIST_______
1) The most accurate colors
(for movies) with the least effort can be achieved by using "Natural" picture mode with color temperature set to -1. This is documented here
after careful, sophisticated measurement.
2) You can access the service menu
Hold "ENTER" down for 3 seconds
There is an entry in the service menu called "Service Mode" which provides many helpful test images. They can be used to check for stuck & dead pixels, as well as panel alignment and other potential problems. [NOTE: There is also a second service menu which can be accessed by holding down "ENTER" for three seconds while the "Pic Shift" selection is highlighted in the first service menu. The limited settings in that menu do not seem as useful.]
Panasonic has released new firmware. Version 1.05 and higher fix several known problems. You can check your firmware version in the service menu under 'Self Check'.
The service menu differences between firmware 1.03 and 1.05 are underlined below:FREEZE MSG (on)
HD OVERSCAN (off)
RUNTIME PRT (on)
FAN FULLMODE (off)
AUTO SETUP (normal)
SD LEVEL (c)
525p OS (off)
Here's what the 1.03 menu looks like (Japanese model):
4) Flicker tweak
. This tweak is a response to vertical banding (VB
) problems. VB
consists of translucent vertical lines across your screen (like jail bars). They are often more noticeable when the content you are projecting consists of large, lighter, solid colors. In movies, VB
could become apparent in a scene where smoke, fog, or sky fills the screen.
Look for "FLICKER ADJ" in the service menu. Settings vary unit to unit, but several people have experienced improved (lessened) VB
after LOWERING the default flicker values even if you do not see flickering on them in this service menu. Make sure you adjust for the mode you are using, or all modes (desk/ceiling). My settings are Red&Blue=23, Green=26.You can further reduce VB by switching the power off on the unit when you are done using it instead of leaving it in standby.
Several theories have been proposed to explain why cutting the power lessens or eliminates VB
, but no one is 100% sure why it works. I have hard wired my projector to a wall switch for this very purpose.
Several people have suggested scenes in movies to test your unit for VB
problems. I have found nothing better/simpler than projecting a full screen solid color - several colors are good for this, I use a bluish gray, RGB=58/110/165
[NOTE: Many users have reported that "flicker" and also "VB
" stabilize over time. After 200 hours I can confirm similar observations on my unit. There is less flicker and less VB
now than when the unit was newer.]
is a problem for both VGA and HDMI inputs but can be easily eliminated with tweaking on the VGA input, and possibly eliminated on the HDMI input IF you have firmware version 1.05 or higher(?) - early reports say this is not the case however.
For VGA: Start by feeding the projector a standard 1280x720 resolution. Since this is not always a resolution that is included with most video card drivers, you may need to install the free Rage3D tweak utility or any similar utility to enable this resolution.LINK to free Rage3D Tweak utility
After you have switched to the proper resolution, run the "Auto" function found in the AE700's position menu to auto set the pixel timings, you may notice that your desktop image is still cropped on the left side. Reboot your machine at this point. For me it came up perfect after reboot, but you may need to re-run "AUTO" again after rebooting.
To confirm that everything is correctly set, you can use Mark Rejhon's test pattern explained here
. Make sure you use the bitmap version (shown below) and tile it on your desktop. To do this, right click the image below, then choose "set as background (or wallpaper)". Minimize all windows, then right click your desktop, go into properties, then desktop, and choose to tile this image.
[Note: the "AUTO" option in the position menu is NOT available on the HDMI input. As stated earlier, you can only fix cropping on HDMI if you have firmware version 1.05 or higher and even then maybe not
6) White flash
. I have never seen this phenomena, but based on user reports it seems to only occur on the HDMI input (and possibly only when feeding an HDCP signal?). Panasonic has suggested that firmware versions 1.05 or higher should eliminate this problem.
The white flash problem may be linked to the scaler/video processor. There also may be a link to certain DVD players, specifically users have reported white flash problems with Denon players more than others, however the problem has been reported on MANY different brands AND on HTPCs (using DVI/HDMI). Other users have reported that they only see the white flash problem when scaling. When they send the projector a 1280x720p signal, there is no white flash problem. If you are using a home theater PC, you should try using FFDShow
(its free) to scale the picture to 1280x720.
The white flash problem may also be the result of inferior cables. Some people using quality cables report no white flash issues (the ULTRALINK HDMIPRO-10M Platinum Series HDMI-to-HDMI Cable has been recommended for very long runs, but it will set you back a couple hundred $s. This cable was tested by an AVS forum member / cable testing nut, and was the ONLY non-optical cable he had tested that was capable of delivering flawless 1080p signals over such great length -- not that it matters to you since the AE700 can't even display 1080p
but here's to future proofing your cabling and avoiding white flashes!). At least one forum member reported a big decrease in white flashes when he changed cables although it did not eliminate the problem completely.
A couple people reported white flash problems (apparently of a different variety) over analog inputs. One forum member has reportedly eliminated his analog white flash problems completely by taking the ASPECT RATIO menu item off AUTO and setting it to MANUAL. Note that this is not possible using the HDMI input. This analog white flash issue may result from the projector's software constantly monitoring the aspect ratio of the source material and getting it wrong occasionally as aspect ratio ID data is corrupted due to poor replay, signal loss/interference, or a damaged disk. The member reporting this believed the white flashes looked like the projector was losing horizontal lock. This seems to be a very rare problem, I have never seen it myself using the VGA input.
7) Peek-a-boo scan lines
. Apparently this is some type of narrow horizontal line noise that can be seen during video which contains a lot of vertical movement (?). I have not noticed this problem on my unit. Not sure if there are any tweaks for it, but I will update if any are mentioned.
8) HDMI Issues
. As already noted, you must have firmware 1.05 or higher to resolve picture cropping problems over HDMI, as well as other issues such as white flash. Early reports say cropping is still a problem on firmware 1.05 though.
Another issue many users have reported is excessive artificial sharpening by default on the HDMI input. You can reduce this by entering the standard "picture" menu and turning down sharpness as far as it will go.
