16×10 LCD Monitors, How do they work?
Many have recommended or at least suggested that the latest herd of LCD computer monitors may make good low cost HD monitoring solutions. The Dell 2405FPW and its HP cousin, the L2335 are typically mentioned.
QUESTION 1:
These monitors are 1900×1200 or 16:10 panels. Curious as to how to they map to 1080 or 16:9 for HD. Do they “zoom”?. If so, how is the quality of the blow up and does it produce any degradation or other issues? Do any of these reformat the picture for a direct pixel to pixel representation of HD input? This would be like a slight letterbox or sidebar.
How problematic is 720p?
QUESTION 2:
While not I am not intending to use these monitors for critical work, I wonder if a consumer LCD HDTV would have better scaling and conversion processing for SD images. Since televisions may be tweaked for tasks they may more commonly do, such as dealing with SD.
Most of these TVs are currently 720 sets. So I am guessing that 1080 crammed into 720 looks better than 720 blown up to 1080.
I know SD is less than great on any LCD monitor. So perhaps I am after the best of the worst.

The 16:9 displays with a very small amoount of letterboxing on the 16:10 monitor. This is how it is set up on the L2335. 720p has a 16:9 aspect ratio.
SD appears a pillarbox, there is always the interlace to progressive issue to deal with as far as quality is concerned since you get a lot of field blending as well as the very small anount of lag because of pixel refresh.
As long as the LCD is connected your CPU, it can have drivers to calibrate. If not, you are on your own with just the on board controls.

Thanks for the anwsers.
720P certainly has the same aspect ratio…but this must be scaled up to fill the display or is there a pixel for pixel option here as well? None of the popular LCD monitors mention 720 in specs. Any opinions of how well they display 720?
Also do you think consumer television HDTVs do a better job with SD material than LCD computer monitors? Do the televisions have any additional processing which helps them produce better results?
If I am a working predominately with 720 material, is one solution a better fit?

Let me look into this – I haven’t tried 720 with the L2335 yet. I’ll play around a bit on Monday.

Hi Chris –
I have worked with many LCD monitors, except for the $15,000 eCinema 23″ display. “They say” it’s teriffic, but I have not seen it.Most of my clients use 720p exclusively, so I have seen most of the popular “pro” displays – bottom line is – they all look the same. I have used the Apple 23″ Cinema, the Dell 2405FPW, the Sony SDM-P234b, the HP L2335, and the stupidly expensive Sony Luma LMD-232, and they are all about the same. It gives me the impression that every one of these monitors uses the same LCD panel made in Taiwan or Korea, and the packaging, or interface electronics is different (like the HP and Dell have analog HD inputs).
I have also tried all these monitors with the AJA HDP, and the Blackmagic HD Link (HD-SDI to DVI adaptors), and they also work, and do not change the way the image looks.So they all look good with 720p, but one thing is for sure – they are all USELESS with standard def video (if you are forced to do a job in SD on this system).
