Hey, about that halo effect on the TM-H. I owned more TM-H units than I can remember, and from my experience this "halo" is totaly normal.bzn wrote:This is an exaggerated picture, its not nearly as bad in person, especially in actual games, but the halo is nevertheless very visible around white text and such.treminaor wrote:Yours is probably one of the worst I've ever seen.
These sets actually have a service mode that draws a horizontal line to help tune G1 (SCREEN VR), which I have done according to the manual.treminaor wrote:raise the screen voltage via the flyback adjustment until just before you see a grey background with retrace lines (lower it back until the background is black again), and then tweak the contrast until you get a good peak white level. Use both the RGB Color Bars and Plunge tests from 240p test suite to evaluate your work while tweaking settings.
I have set B1 voltage to 53V as recommended and subjectively both settings yield the best picture when set as recommended.
Lowering the contrast does not really help the halo.treminaor wrote:Does the bleeding get better when you turn down contrast significantly?
Effect does change depending on viewing angle (photo taken from center axis) which leads experienced people to believe that its just internal reflections off the glass. However, other users of multiple TM-Hs also report that effect varies between units. Could be due to wear or just psychological though.
Those monitors have a very dark CRT tube, compared to a Sony You can easily notice that when turned off, a tube of a Sony monitor will look grey, but the TM-H is pitch black. Also they are quite bright, so in my opinion this is why there is a halo.
And hey, are You sure about those hours on the TM-H? The values on the counter can be easily changed, and I don't think it works like in the DT-V monitors (x100). So how can You be sure that it's showing the correct hours? As there is nothing stated in the manual about this.
