『貳』 這種動態圖怎麼設置，滑鼠移動就有波紋的那種
這是水波紋特效，通過一定演算法實現的，我有相關代碼和寫好的程序。
『叄』 手機屏幕分哪幾種,哪種最好
手機屏幕不同於電腦屏幕
從材料上來分
有stn，老式液晶顯示屏，俗稱「偽彩」，最為省電
有tft，一般現在流行的液晶顯示屏，顯示效果同檔次屬於最好，但最為耗電
還有ufb，三星特有的屏，據說跟tft顯示效果差不多，但實際要差點，但比tft要省電
從解析度上來分，目前手機有一般的，128*128的，120*160的，有208*208的，有320*240的，有640*480的，甚至有800*352的，還有412*352的。
等級上來分，除了一些個特殊的解析度，320*240,我們一般稱之為qvga級別，640*480稱為vga級別，手機上的800*352的，一般習慣稱之為wvga，雖然不是真正的wvga。
從發色數上來看，有256色，4096色，但這2種均已淘汰，65535色的也瀕臨淘汰。現在的主流是26萬色，高端機一般都是1600w色
據我所知，目前手機屏幕就這幾個解析度了和這幾個等級了
『肆』 電腦玩大型單機游戲出水波紋是顯卡的問題還是求高手
1顯卡驅動，首先確定的是你電源沒問題，900W 不是電壓問題。然後付現率100%不是電磁干擾的問題。顯示器別的游戲沒問題不是硬體問題。
然後現在就是顯卡和顯示器的傳輸線問題了。線不好可能會有波溫。
然後就是顯卡驅動，這個很重要。如果驅動不對，跟不上游戲的引擎演算法，會出現問題，你高配置後的效果演算法和低配置不一樣的。所以換更新驅動看看如果還不行，那就不要玩有問題的游戲了。。。如果很多游戲都這樣 找電腦店檢查時最好的解決辦法。
『伍』 液晶顯示器玩游戲有水波紋
液晶顯示器和傳統的CRT顯示器，解析度都是重要的參數之一。傳統CRT顯示器所支持的解析度較有彈性，而液晶的像素間距已經固定，所以支持的顯示模式不像CRT那麼多。液晶的最佳解析度，也叫最大解析度，在該解析度下，液晶顯示器才能顯現最佳影像。
目前15英寸液晶的最佳解析度為1024×768，17～19英寸的最佳解析度通常為1280×1024，更大尺寸擁有更大的最佳解析度。
液晶顯示器呈現解析度較低的顯示模式時，有兩種方式進行顯示。第一種為居中顯示：例如在XGA 1024×768的屏幕上顯示SVGA 800×600的畫面時，只有屏幕居中的800×600個像素被呈現出來，其它沒有被呈現出來的像素則維持黑暗。目前該方法較少採用。另一種稱為擴展顯示：在顯示低於最佳解析度的畫面時，各像素點通過差動演算法擴充到相鄰像素點顯示，從而使整個畫面被充滿。這樣也使畫面失去原來的清晰度和真實的色彩。
