Hi all!


Am bit confused about what resolution is the best suited for me.

A use a BG 801 with hptc radeon 7000. Screen with 72". I have tried 960x1440 64hz, 720x1080 74hz, 1024x768 64hz, but not really got the perfect picture. Does anyone run the same setup as I´m?


Need some advice

Hi Henrik.


Sounds like you live in a PAL country. For viewing PAL material you should try 1152x864 @75hz this is the pal resolution x 1,5 and refresh x 3. For viewing NTSC material, try 720x1080 @72 hz, or 960x1440 @72 hz if your pj supports it.


I hear that many people get more natural motion using lower refresh, since your card supports it, you could try the same resolutions mentioned above but with 48 hz for ntsc and 50 for pal.


Hope this is helpful to you.

I have tried both resolution, but the problem is that a can´t get the focus real good. What a want is a good instruction, how to calibrate the focus. The levels on the CRT neck, what exactly does they do? Also the trim pots for the g2 adjustment (I think that´s it). How to calibrate these.

I use 1024*768 75Hz on a 4:3 screen that's 230cm wide and even after an ISF calibration and setup by a local Barco guru the Barco is still not 100% sharp.


I don't have a problem reading the fonts on the windows start menu, but very small characters tend to get a bit more difficult from some distance (text below desktop icons still OK though).


According to various 801s owners, this is something we will have to live with and is unavoidable because of the following limitations :
  • tubes are air coupled to lens, not liquid = some light leakage -> less contrast. Scattered light also decreases sharpness.
  • no electromagnetic focus as the more high-end Barcos : less sharp image


Even though the BG801s can easily handle 1440*960*72 in 16:9, that resolution is nice to avoid scaling artefacts, but it's not exactly sharp. That resolution at 48 Hz really gives a nice and crisp image for HT on the Barco.


So if desktop performance is also important to you, the advice is to save for a 808, 1208 or 1209 . For upscaled DVD playback, the BD/BG801s is certainly good enough when you have it correctly focused.
