我的旧HP8590a需要一个新的显示器。
所以我购买了一个标有OmniVision类型的新盒子装置。 相同尺寸,相同的连接器。 但是,似乎水平同步不适合HP8590a。 根据我能找到的关于这些监视器的信息,它们可以处理宽的水平扫描频率范围。 从头到尾调整水平同步控制不会使显示器对齐。 我能得到的最好的是一个稳定的显示器,但看起来有5个图像。 我会在这里附上一个屏幕截图。 关于这个问题的任何想法? 以上来自于谷歌翻译 以下为原文 My old HP8590a needed a new display. So I purchased a new in box unit marked as an OmniVision type. Same size, same connectors. However, it appears that the horizontal sync is not proper for the HP8590a. According to what I can find about these monitors, they handle a wide horizontal sweep frequency range. Adjustment of the horizontal sync control from end to end does not bring the display into alignment. Best I can get is a stable display but having what appears to be 5 images. I'll attach a screen shot here. Any ideas on this problem? 附件

我成功了。
问题是同步频率。 要在HP8590A中使用OmniVision LP0615E3Y监视器,需要更改监视器的水平同步频率: - 用4300pf / 100V聚酯薄膜替换电容器C11(4700pf / 100V)(在我的情况下,我添加了一个串联的盖子来修剪值) - 您必须调整显示器的水平位置和线性度以及垂直位置和线性度。 - 您必须更改HP8590A的垂直和水平位置的显示器校准值(确保保存校准数据)电容器的更改将使显示器的水平同步频率充分在范围内,以便它可以与HP8590A的水平方向一起正常工作 同步脉冲频率。 我想可以通过一些调整来优化垂直线性度,但它足够可调,不需要硬件模块。 校准测试通过就好了。 祝你好运! 以上来自于谷歌翻译 以下为原文 I was successful. The issue was sync frequency. To use the OmniVision LP0615E3Y monitor in the HP8590A it's necessary to change the monitor's horizontal sync frequency: - replace capacitor C11 (4700pf/100V) with a 4300pf/100V mylar (in my case, I added a cap in series to trim the value) - you'll have to tweak the monitor's horizontal position and linearity and also the vertical position and linearity. - you'll have to change the HP8590A's monitor Calibration values for both vertical and horizontal position (be sure to save the calibration data) The capacitor change will bring the monitor's horizontal sync frequency sufficiently in range so that it will work properly with the HP8590A's horizontal sync pulse frequency. I suppose some tweaking could have been accomplished to optimize the vertical linearity, but it was sufficiently adjustable that no hardware mods were needed. A calibration test passed just fine. Good luck! |
