48G vs 48GX Black LCD vs 50G display Message #1 Posted by Hal Bitton on 12 Sept 2006, 9:49 a.m. Hi Folks. I recently acquired a nice 48G, my first graphing model. While the power of this machine astounds me, the display seems a bit weak, no mater how I adjust the contrast. I find myself having to seek as much light as I can find to use it, and even then I have to hold it at a certain angle to see the display well. For anybody who has seen all three displays (48G blue, 48GX black, 50G), is there a noticable difference in the viewability of the latter two machines over the first one? Thanks, and best regards, Hal

Hi contrast pixellated LCD was not available in 1990. The 48S is even less contrast than the 48G. Edited: 12 Sept 2006, 9:56 a.m.

Re: 48G vs 48GX Black LCD vs 50G display Message #5 Posted by Thomas Okken on 12 Sept 2006, 10:22 a.m., in response to message #1 by Hal Bitton You may have a faulty unit. I have a 1993 48G, and while its display (blue) is certainly not the greatest, I find it has a wide viewing angle, is crisp, and readable even in low light. I could try taking a picture and posting it if you wish to compare. - Thomas

Re: 48G vs 48GX Black LCD vs 50G display Message #7 Posted by Thomas Okken on 13 Sept 2006, 6:54 a.m., in response to message #6 by Hal Bitton Here's a picture of my HP-48G, 1993 vintage. I took it in a dimly lit room, under a 60 Watt reading lamp, without flash; the exposure was a bit long, hence the blurriness, but you still get a pretty good idea of the contrast. In reality, the contrast is actually better than in the photograph. - Thomas Edited: 14 Sept 2006, 3:56 a.m. after one or more responses were posted

Re: 48G vs 48GX Black LCD vs 50G display Message #8 Posted by Hal on 14 Sept 2006, 12:39 a.m., in response to message #7 by Thomas Okken Thanks for the pics of your 48G display. I have a pic I would like to post, but I guess I don't know how. Putting the HTML script in the thread is no problem, but how did you upload your picture to the museum website? Any help appreciated. Hal
