Anyone know the viewing angle for the T4010 SXGA

[star_warz]

Anyone know the viewing angle for the T4010 SXGA? I'm still debating the Tecra and the T4010. I'm torn. Can't any Tablet / LCD manufacturer make a WSXGA screen soon? I'm tired of waiting for a new tablet.

I was told by a customer service rep that it is 110 degrees. I'll let you know if I discover otherwise when I get it.

The fact that XGA screen doesn't pool (unlike toshiba's SXGA), you get much accurate pen pin point screen. regardless of viewing angle, i think that it self is the selling point.

Hi arclite

I'm unfamiliar with the term 'pool'. It sounds like a pressure related visual artifact on the screen, but if that's it, I can't get this to happen on my M200.

Can you clarify?

Thanks

Absolutly. Pooling is exactly that, pixle distortion upon contact. Hydis screens (XGA) unlike Toshiba (SXGA) lays them horizontally instead of vertically for its pixles. This nearly eliminates pixle pooling even with force.

Now, know that SXGA also will NOT pool. But here is the kicker. Since Toshiba had to elminate pooling on their "poolable" screen, they had to insert thicker transparent glass screen between you and the display. This is fine and dandy on a normal laptop, but for tablet pcs, you have to use your pen. When you do, there is a significant space between the tip of your pen and the actual "displaying pixles". Therefore, you may not feel your eyes and your hand co-relating as well as you want. Think of it as a glass on a table. What you see and what you touch can sometimes be a miss.

On Hydis XGA screen, pooling is almost none existant, so therefore no need for thick serperating glass between the pen and the display. This way you get more accurate feel between what you see and what you tap.

From the "Pen Computing" article, I had gotten the impression that the problem was less the glass screen -- which I gather Hydis screens have also, to protect the display -- and more the fact that in the Toshiba display, the glass screen can't touch the actual disply. So there's more distance between the display and your pen then if the glass were bonded directly to the display surface (as in a Hydis display) and there's also more problems with glare because there are more glass-air interfaces.

Disclaimer: I'm not an expert, what I read in the article is the sum total of what I know about Tablet PC displays. :-)

I think the bottom line is that right now, you can get wide-angle displays OR you can get high-resolution displays, but you can't get a truely wide-angle, high-resolution display. So you pays your money and you makes your choices.

I'm assuming (correctly?) that the high-resolution display that the SXGA T4010 uses is the same one that the M200 uses, minus the grainy screen covering. I don't think there's any other kind. So I wouldn't expect the viewing angle to be any different than the M4, since they use the same technology. Please take this with plenty of salt, though, as I said I'm no expert. :-)

I have both the TC1100 and the M200 and do not find that I have any greater trouble maintaining a sense of eye-hand-inking co-ordination with the M200. It's not an issue for me moving from one to the other.

Both machines display some parallax error, but to my eye there is no signifcant difference. This is easily overcome by
- holding the stylus in the same way when calibrating, as when actually using it.
- focusing on the cursor rather than the tip of the pen. We do this all the time with other pointing devices.

I'm not an expert on this, but I've read one review (Can't remember the source) and since then I've gotten the impression that the M200 screen actually has thinner glass than any other tablets out there, thereby having the least parallax problem. So that is wrong now. If compare between M200 and T4010, does that mean that T4010's glass is thinner and has less parallax?

p.s: I don't understand why people keep making this mistake. It's SXGA+. Not SXGA (1280 x 1024). There are 2 different thing. Also, SXGA+ means 1400x1050. Not 1440x1050. Not 1400x1200. Not 1440x1200. It's exactly 1400x1050. No more, no less. Please!

I'm sorry about the XGA, SXGA, SXGA+ mistake. I didn't really realize the differences. I knew the screen was 1400 x 1050, but I didn't know it was SXGA+ for that.

Thanks for the information
