These days you can tell by price.The response time is a dead giveaway as well. Viewing angle tells you too. So Specs and price. You should tell us the model so we can know for sure. Besides, its an Acer...
I have the Dell 2407 for 8 months now (700 Euro, and that can be considered cheap in Europe ) and I am very happy with it so far. I had a Sony 19" CRT before that and the transition was rather painless. Good colors, very bright above the lowest setting, lots of inputs, the latest revision supports 1080p in the correct aspect ratio via VGA and DVI. Refresh rate is also excellent. Rarely I feel like I saw screen-tearing during video-editing. But I could be wrong and I never felt distracted or anything.
I wish, black levels were a bit better, but I guess that´s common among all LCD-screens, not a specific deficiency of the Dell 2407.
It has tiny usability-issues that bug me. You have to press the input button twice to change inputs and the display goes into powersafe the second it doesn´t get any signal but I just personally don´t like that.
I´m not telling you to buy it, since I don´t know the LG, I´m just saying it´s not a bad monitor and I didn´t regret the purchase at any point!
If you want a monitor for serious photo editing that will reproduce colors as they really are you have to look into S-IPS panel technology. Be prepared to pay for it though. Apple Cinema, NEC, Eizo, Lacie are some brands that use S-IPS.
Dell 2407WFP used to have S-IPS but are now shipping with the lesser S-PVA panels ( I think the 30" Dell is S-IPS )
The 2407WFP was never an IPS. Always PVA. The 20" was the one with the panel lottery. The 24" HC version now has an updated PVA with a more full color gamut (92%).
Eizo uses PVA/MVA in their "cheaper" line of displays. Of course, the panel doesn't make the display, which is why Eizo is still one of the best.
