TV Size comparison and mounting

April 14, 2009

As the TV was delivered today, i compared it with my real Pinball:

pinball-with-tv

I had an idea how to mount the tv: I will insert some screws in the back of the TV. Then i can lay the tv down on a board with 4 holes in it. The whole tv is relatively flat at the back, so that it will rest relatively stable on the back.

Sorry… pictures from my cell phone.

Where to put the screens

April 12, 2009

I just made a little image where to put the screens inside the table.

I think i will put the board which stabilises the table between the DMD and the TV. With some holes in it for airflow.

Also it shows that to be authentic (a normal DMD is about 60% of the width of a pinball table) the DMD should have a width of approx. 24 cm. For a width of 23 cm i would need a 10.4 Inch display. Although i could not display the backdrop… I will think about this.

Sorry for people thinking in Inches… the metric system…

178 degrees promised…

April 11, 2009

Today I have been at a local electronic discounter with a friend who was lookking for some DJ-equipment. I could not resist to take a look at the LCD TVs they had there. They had the 42 Inch version of the Toshiba AV 500 P there and i could look at the promised 178 degrees of viewing angle.

Me and my friend looked it from the side and we both said that in comparison to the other LCD-TVs the AV 500 P has a great viewing angle. So my conclusion for you: Dont buy any TV – look for the viewing angle! Although the screen was not perfect at extreme viewing angles, it always was OK. I would say that between 120 degrees it was nearly perfect and up to 150 degrees it was still good. Sitting at the side of the table 60 cm above the table and 1 meter to the other side of the screen would give a viewing angle of approximately 30 degrees from the side – makes 180 degrees – (30*2) Degrees = 120 Degrees  from side to side. So the image will be good.

What i also found out – unfortunately – was that the buttons under the screen look approximately 2 mm out of the bezel. That is not so good, but not a big problem, since i can mount the TV 2 mm under the glass. I just have to stabilize the glass a little bit. As i plan to mount a black cardboard under the glass with cutouts for the screen and DMD this should not be a big problem. I also have in mind that i maybe have to mount a infrared emitter over the infrared “eye” of the TV, if it turns of to be a pain to switch to HDMI input.

I think the TV as well as the U-HID-G will arrive on tuesday (because of easter). According to the tracking they are already in my city.

What TV?

April 10, 2009

What TV to choose is a question of price versus the needed features:

  • good viewing angle (since i look from the side)
  • the bigger the better :-)
  • Full HD?
  • Pixels that are quadratic
  • Small bezel around the Screen
  • HDMI input

The first thing i thought of was: should it really feature full HD? OK, this would be great, but full-HD TVs are more expensive as HD-Ready TVs. But more important is the viewing angle. Since LCD TVS are made of layers. If the density of the layers (the resolution of the TV) increases, the viewing angle decreases because the RGB overlay somewhat shifts over the LCD-shutter panel (i researched this for my MAME (TM) cabinet and bought an arcade monitor for this because there was no good LCD-Monitor that time).

Then i researched the prices for full HD LCD-TVs – nooooo gooooood! :-(

OK… Since the resolution of Visual Pinball tables are not so great either, and 1366 x 768 pixels is somewhat the standard for 16:9 tables for Visual Pinball, i decided for a TV that should have 1366 x 768 pixels. Also this resolution has exact quadratic pixels so that i don’t have to bother about stretching issues.

Searching a little bit the internet i came across this LCD-TV:

The Toshiba REGZA 32 AV 500 P

I found it at a german Web-store (Redcoon) for 345€.

The best: it has a viewing angle of 178 Degrees. Exactly what i was looking for.

The measures (without base) are:

79,6 x 51,2 x 9,9 cm

So 51,2 cm height… i have a maximum height of approximately 54 cm inside the Ramvik table. So it should nicely fit in.

OK, it has a relative big bezel, and the reviews are noit so great, but the price was what was really counting… The overall Price of the table should range about 700€ (without computer).

So i bought it… No way back. Now i really have to build the table.
