You need to set up the Powerstrip times first and then leave the pc alone. Then adjust the pj until you get 1:1 mapping. I haven't had my 13HD for some time now and I can't remember the settings on the PJ. I'm sure somelese around hear can help out.

I have a PLV-60. Maybe the following helps.


Warnings first:

- I'm making up the procedure (not following it) so I may have missed something.

- I'm not making any claim that these settings are 'optimal' or even 'safe'. They work for me though.


Down to business:


0) Get PC into 1024x768.


1) Use the PLV-60 menus to set

Total dots 1504

Total lines 803

Display area H 1360

Display area V 768


I guess the PC screen is a mess but the PJ menus work.

Save these settings (On mine the menu for this is 'Stored').


2) Select Auto Adjust on PLV-60 so you can see the PC screen again.


3) Adjust powerstrip:


.. Horizontal

Active 1360

Front porch 16

Sync width 104

Back porch 24

Total 1504


.. Vertical

Active 768

Front porch 16

Sync width 3

Back porch 16

Total 803


I use the following command line for this ...


"C:\\Program Files\\PowerStrip\\PStrip.exe" /T:1360,16,104,24,768,16,3,16,72484,2048


(I have no clue what the 2048 means)


The PJ should sync automatically (using your new stored PJ mode) with the picture clear, maybe displaced horizontally or vertically.


4) Back to PJ menu. Adjust ....


Horizontal

Vertical

Fine sync


The effect of these will be obvious (you need Mark's pattern for the fine sync)


............


I've used my PJ for ~1200 hours so something must be right :)

Yes, I have a 1360x768 desktop with Mark Rejhon's test pattern wallpaper and it is perfect.

I have solved this and various other problems by looking at test patterns from Displaymate (a software product) and playing endlessly with the dac settings in the service menu. There's various views on this kind of thing over at Big Picture . I made progress after reading some posts from BigRalf3. You may have to dig around in the archives though.

I simply haven't changed the bulb yet.

Sorry more questions



Is posible than you say me all numbers included pixel clock and you got the problem of more visible pixels with this settings.


And how you change dac settings I know put the sevice menu but how change the numbers into service menu.



I got a shadow vertical line lightly visible in the right side of the screen too.



Best regards and thanks

Tonight I probe other time with the line direct to execute and the screen turn red and when y change the pixel clock not improvement the screen .


And I don't understand how this numbers are good in your plv-60.


Best regards


Tonigh use in a compare the component dvd player and htpc way input 1 vga and the improvement is overall.


I think than this way component are impressive but from htpc is the more near to cinema than I see until the moment (is possible than I don't see to much) but the image is more clear and sharp and I achive blacks and whites very goods.


Only I have improve the skin colors than some times got lighty yellow brights.





How dvd software use for htpc.




Best regards and thanks

Javier,


I'm not certain that I understand all your questions. Ask again if I miss something.

This doesn't sound right unless your screen is several meters wide. The dot over this letter 'i' is one pixel. I can see this if I sit one screen width away (i.e. screen is 2m wide and I sit 2m away) but I doubt I can see it at two screen widths (4m away in my case).

The pixel clock in pstrip is 72.484 Mhz. This is the 72484 number in the pstrip command line that I quoted earlier.

So the vertical refresh rate is 60.017 Hz and the horizontal scan rate is 48.194 kHz.

As I said above, are you sure that you are seeing the pixels? I don't have a component dvd player so I don't have to live with a comparison :).

Anyway for my HTPC I try to have the clearest possible desktop. This means:

- pixel perfect using Marks pattern (or displaymate)

- fine sync adjusted (again using Marks pattern)

- no visible shadows around vertical lines (caused by ringing from the cable or mis-adusted dacs).

- no scaling by the pj. ('true' mode on the pj menu)

- lastly adjust the HTPC overlay settings using AVIA.

This may help. I tried to isolate the problems that I saw on the desktop or in movies to artifacts in test patterns. Then I experimented with the service menu while looking at the test patterns.
Quote:

In my case I used displaymate test patterns to work out what colour the problem was in. Using the displaymate 'video bandwidth' test pattern I could clearly see that the problem was in the blue and not in green or red. So I played with anything in the service menu with a name that suggested that it affected blue only. Eventually I got rid of the line/shadow by using service menu setting #046.

Here's an idea. Why don't you read you pstrip settings from the screen, read your pj settings from the menu and post them. I can see if I have anymore ideas.

I used to have this problem. I don't know exactly how I fixed it but I do know that I have never changed any color balance parameters, only dac settings.

Using patterns I think you will find that you have a problem is in the grey scale where low intensity greys look yellowish. The eye is more sensitive to problems with green, rather than blue or red. And the brain is particularly sensitive to inappropriate face color.

How dvd software use for htpc.
I use WinDVD 3.0 or TheaterTek 1.5. Some knowledgable and respected people here are strongly favour of TheaterTek for PQ. I find WinDVD more reliable and the PQ differences are not obvious to me. Maybe I haven't worked out what to look for.


The only adustment that I have made is to use AVIA to calibrate the overlay.
