Lockscreen wallpaper... again

---

Hi,

I've been playing around transferring files onto my phone, but I just can't get my lock screen to look right.

1. Does anyone know what the exact dimensions of the lockscreen image should be? I read 320x480 somewhere, but this isn't correct. I've also tried 360x380, 340x480. Maybe it's 345x480? I want to get this right because...

2. Whenever I set an image onto the lock screen, the phone seems to compress the image really badly and I see loads of jpg artifacts on the parts that should be solid colour. I'm hoping that if the image is the right size, it won't convert/re-sample/re-compress the file.

Any ideas?

The stock ones are 320 x 455, and I've had good results using those dimensions for my own images.

Im sure i read that converting your image to a png and using that instead of the png file gave better results also. Not 100% on that though lol

.png gives better quality than jpg.

320x455 px is the right size. But everytime you set wallpaper, HTC software it re-compress as JPEG in tragical quality. PNG or JPEG, that makes no difference.

Will be nice software like Wallpaper Set & Save for lock screen wallpaper. But I can't find something like that.

Not my experience. My own images are usually desktop 'papers resized and/or cropped to 320x455 and saved as JPEGs, and provided I ensure the green 'crop box' is expanded to encompass the entire image when selecting the lockscreen they look just as good as the originals.

I've tried many images. At most (as you) cropped or resized desktop wallpapers. I prepare the correct size and copy to phone. I keep JPEG at 90 to 100% of quality and also convert it to PNG. And every image was resampled during setting up as lock screen wallpaper. Everytime its quality goes rapidly down. Even I used exactly the same way like you.

It is not good visible on landscape wallpapers with. But on artifical images it's very big problem. It blurs every contrast line on image.

Here you go.... see what you think. lockscreen.zip

Not perfect, but it was a rush job. Resized from 1280x1024 to ???x455, then cropped to 320x455. Saved as JPEG @ 100% for use. Photoshop Elements 7 used. If I had more time I'd probably play with the sharpening to compensate for the downsizing.

Also having this issue with this image..

I have problems with all images. But on this it's good visible. And as Shluggity's screenshots shows, it's not only my problem. I think it's not good
