Well...just came back from the store - got a chance to see the monitor. Here's my verdict:
The store also had LCDs from LG, NEC, Radius, NFren and Viewsonic for me to compare with. All the other brands were 15" LCDs, this Hyundai being the only 17".
The colour contrast and brightness were excellent, easily matching the quality of the NEC. I thought the contrast and brightness were a step above the LG and Viewsonic, and miles ahead of the Radius and NFren. The Radius and NFren had problems displaying the default Windows XP desktop theme, not showing very convincing hues of blue and green. The Hyundai monitor showed the colours very brightly, just as well as the NEC LCD. ClearType was enabled, and the text looked very crisp. I opened Word and was typing with 8 sized font, and had no problems reading it. Desktop display was excellent (in my opinion at least), so those interested in this monitor mainly for business/work, they should be more than pleased.
I didn't notice a single burnt or stuck pixel on the screen, as I switched between many different backgrounds and plain colour backgrounds to test this. Hopefully this is an indication of the quality control at Hyundai. I was also looking for colour distortions but found that the contrast/brightness/balance was in general very consistent. I know some LCDs have problem displaying true black, but that didn't seem to be an issue for this Hyundai display.
I watched a few AVIs, MPEGs and DVDs on the screen, and the Hyundai screen played them just as well as any good LCD I've seen (mainly NECs and Samsungs). There was very minimal motion blur, but when I tested the DVDs on the Radius and LG screen, they suffered quite more from the blur. Unfortunately, the store didn't have any gaming software for me to test out in that department. I might go back in a few days with my own software and ask them if I could install it to test. The computer was running a GeForce4 MX card, using the analog input - not the DVI input. So I can only assume it might have looked even BETTER had it been using the DVI. There was a 4-way monitor input switch, so I was limited to displaying via the analog cable.
The construction of the monitor was also very good. The pivoting mechanism felt solid, and smooth at the same time. The NFren monitor had a really cheap feel to it, particularly when you pivoted the monitor or angle it vertically. Just a word to the wise though, the monitor I was looking at was the OEM version, so it was plain beige/white-ish, not the stylistic silver/black that is on that HyundaiQ page. So make sure that ESystor store is actually selling the retail version of the monitor (if the aesthetics are important to you).
I hope that's a decent preliminary look at the monitor for you guys. I also had my doubts about the monitor, being so much cheaper than competition with similar specifications, but rest assured - it's not some cheap makeshift LCD. The display quality surprised me since it was on par with the NEC.
