Are There Affordable Low-DPI Large-Screen LCD Monitors?
jtownatpunk.net writes "As time goes by, I find myself supporting a greater number of users moving through their 40s and into their 50s (and beyond!). I notice more and more of them are lowering the resolution of their displays in order to 'make it bigger.' That was fine in the CRT days, but, quite frankly, LCDs look like crap when they're not displaying their native resolution. My solution at home is to hook my computer up to a big, honkin' 1080p HDTV, but that's a bit of a political risk in an office environment. 'Why does Bill get a freakin' big screen TV?!' Plus, it's a waste to be paying for the extra inputs (component, s-video, composite), remote, tuner, etc. that will never be used. And a 37-47" display is a bit large for a desk. So here's my question: Is there a source for 24-27" monitors running at 1366x768 that are affordable and don't have all of the 'TV' stuff? Or is my only choice to just buy 27" HDTVs and admonish the users not to watch TV? (And, no, just giving them big CRTs is not an option. Most people would rather stare at a fuzzy LCD than 'go back' to a CRT.)"
Easy. Get a 30" Desktop LCD like the Dell 3007wfp and run it at exactly 1/2 its native vertical and horizontal resolutions (1280x800). You essentially get the same quality as if it were the native resolution (well, one to one mapping at least) and none of that crazy TV stuff. The best part is that if somebody with, well, "normal" eyes wants to use the monitor in its full 2560x1600 glory, they can simply switch the resolution.
I think the real problem here is that the software is rendering text way too small. Tons of websites out there insist on ridiculously tiny font sizes like 8 point.
Apple had at one point a plan to give OS X resolution-independent rendering, so that UI objects are always displayed at the specified physical size independently of resolution. That seems to have fallen by the wayside, but this is part of the correct solution--the other part is to alow the user to just say they want everything to be displayed larger at a specified ratio.
Are you adequate?
And all sorts of business critical applications that use unscalable texts in the UI. Now you can blame the application for not scaling but usually just buying a bigger screen for the user is a lot cheaper than having the application fixed (if it is even fixable at all).

Q: "Why does Bill get a freaki'n big screen TV?!"
A: "Because Bill doesn't bother the IT guy with stupid questions like this one."
So my solution is to hand out reading glasses to the older users I support?
No. But recommending a visit to the opticians to any users who complain of bad eyesight would be a good idea, regardless of age. Are you planning on getting comfy sofas for those that don't like the office chairs too? If there's a genuine medical need for special equipment like a larger monitor then of course it's good practice to provide that where it's economically viable to do so. But that's after they've sought medical advice and can support a need for special treatement. The reason you need to worry about other staff asking 'Why does Bill get a freaki'n big screen TV?!' is because you don't have a good explanation for it. That should tell you evrything about the situation.
To summarise the summary of the summary: people are a problem. ~ h2g2

On a related note apparently reading text that is too small does have its downsides:
Readers were asked to read under six especially demanding conditions known to cause eye fatigue. These were: reading small text sizes; reading low-contrast gray text; reading with a light source behind the reading material to cause glare; reading from too close a distance, which causes the eyes to point inward towards each other (convergence stress); reading from variable focal distances (accommodative stress); and reading while wearing glasses that simulate an astigmatism (refractive stress). While people were reading under these extra stressful conditions, we measured the activation in the orbicularis oculi muscle with a sensor placed 1.25 cm below the eye. Readers reported eye fatigue after reading under each of these conditions. Small text sizes, low contrast, glare and refractive stress all resulted in increased activity in the orbicularis oculi, while convergence stress and accommodative stress did not, though after reading in these two conditions, readers are more likely to report headaches and pain coming from behind the eye. Stressors such as small text size and glare are reported as irritation on the front of the eye.
My personal experience relating to computer screens is that growing up I had CRT, until my mid-twenties when LCD started becoming affordable. Up until I was about nineteen I did not know about changing resolutions on my screen and thus ran in Windows native resolution (which in the case of 95/98/XP seemed to be 60hz). I suffered from frequent migraines that would start with flashing lights in-front of my eyes and end with two days of such blinding headache that I was unable to do anything buy stay in bed, inside a dark room, and during the first day I would throw up at least once. Several days after such an episode I would feel like I was serious hungover. Turning the refresh rate up to 100hz effectively cured me over night, I did not have another episode until my late twenties when I played console with a mate on a CRT TV an entire evening.
Perhaps a bit of a digression there. But do not underestimate the importance of a good screen and a comfortable text/gui-size; undue strain on your eyes can significantly reduce the quality and quantity of your work.
