New Monitor Problems (DGM L-2248WD)

Hi,

Yesterday - after having owned for years a great but incredibly ugly/heavy 19" CRT monitor - I ordered/purchased the Aria/Digimate 22" L-2248WD:

This morning I received the above item - and, actually, the Brightness was 400cd/m2, not 300cd/m2. See:

(so I think the write up was confusing it with the very similar - and constantly advertised - DGM L-2231WD, which does indeed have a 300cd/m2).

Anyway, I am having problems with the new monitor! When I first turned it on, I had extreme problems 'getting into XP Home' - the screen was either blank/'dead' or flickered madly. Aha, I thought wisely, I need to change the refresh rate from 75khz to 60khz and change the display resolution to 1680 x 1050. Eventually, in between the mad flickering, I just managed to dive into Desktop Properties and change these settings - and then everything seemed fine (well, almost, but I will come back to that later).

However, after rebooting into XP I had the same problem again. However, when I booted into Vista Ultimate - as I have a dual boot system - I had no problems: no flickering or anything. It seemd to automatically adjust the settings - like Refresh Rate, etc.

I then re-plugged my old CRT monitor just to check the XP settings - the refresh rate was still 60khz, but the display resolution had defaulted back to 1280 x 1024, so I put it back to 1680 x 1050. Rebooted - but still no luck, but Vista is still fine. I've subsequently gone back to my CRT to re-check the XP settings, but they seem OK now (60khz refresh rate, 1680 x 1050 resolution).

One other thing to note. In both Vista and XP (on the one time I managed to get into it successfully) some of the options in the OSD Menu seem denied to me. So in the main menu the Auto Set Up option is greyed/blanked out - as is the entire Display Adjust option. Also, within Colour Temperature I am unable to access the Auto Gain option, and the main Auto Tuning button on the front of the actual monitor seems to do nothing.

Now, any ideas for me? Any advice would be greatly appreciated, believe me!

Thanks,

DANNY
