Where are all the high-resolution desktop displays?

When we covered LG’s new 440 PPI display, several of you asked why small panels were getting all the high-resolution lovin’, and when we might see high-rez desktop and laptop displays. We’ve discussed the concept of a “Retina display” as it relates to both handheld devices and widescreen televisions, but we’ve not touched on desktop displays all that much.
Desktop monitors, as it happens, are something of the odd man out in the display industry. The Occupational Safety & Health Administration (OSHA) defines optimum viewing distance as between 20-40 inches (50-100cm) depending on display size. That’s much closer than the 6-8 feet (1.8-2.4m) typically assumed for television viewing, but still considerably farther than the 8-15 inches used for smartphones and tablets. As I type this, I’m sitting ~32 inches away from a 27-inch monitor with a resolution of 1920×1080, or 81.59 PPI. At that distance, my monitor would need to pack at least 107 PPI (pixels per inch) in order to qualify as a Retina display. This one doesn’t — and I can tell, if I make a point of checking.
We spoke with Max McDaniel, Applied Materials’ Chief Marketing Officer for Displays, to get a better perspective of the issue.
In order to understand why desktop resolutions are stuck at the low end of the spectrum, we need to first acknowledge that higher PPI displays do exist. Newegg stocks multiple 27-inch displays with a 2560×1440 resolution in the $850-$1600 range. At 108 PPI, that’s high enough to qualify as a Retina display at a nominal 32-inch (80cm) viewing distance. There are medical displays that offer much higher pixel densities; NEC sells 20/21-inch screens with 2048×2560 resolutions — but they’ll set you back five figures.
One of the reasons why we don’t see high-resolution monitors is because the display market is unevenly split between an overwhelming majority of people who want cheap, bright, fast screens, and a minority of professional users who need features like 10-bit color, multi-standard support (HDMI, DVI-D, DP), audio jacks, multiple USB ports, and the least amount of backlight bleed-through it’s possible to buy. Mass market monitor prices are highly elastic, meaning that price tends to have a strong impact on purchases.
One reason why it’s much easier to increase the resolution of a smartphone/tablet display as compared to a desktop monitor is that in a handheld device, the screen is just one component. Have a look at iSuppli’s estimated iPad 3 build costs and you’ll see what we mean.
Display Resolution
The iPad 2 (16GB, no WiFi) has an estimated BOM (Bill of Materials) of $236.95 and a total BOM of $245.10 once manufacturing is included. The iPad 3, with its high-resolution display, has a BOM of $306.05, $316.05 with manufacturing. The iPad 3′s screen is responsible for much of that increase, but even at $87 (up from the iPad 2′s $57) it’s only 27% of the total BOM.
A desktop monitor is, by definition, all about the monitor. Panel costs can range from 50-75% of the total display price depending on resolution and size, and that’s where display manufacturers start running into trouble. In a highly elastic market, any attempt to push higher resolutions drives up costs, which drives down demand. As a result, it’s been more economical to push higher resolutions, 10-bit color, and a host of other niche features toward the professional market, where buyers who need them will pay top dollar.

Don’t hold your breath

Applied Materials released a PDF on display market trends earlier this year that shows where it expects resolutions to move upwards — and where it doesn’t. The degree of shift is proportional to both the size of the screen and the distance from the user, and it suggests that the largest panels will see precious little shift, if any.
There’s some early work being done around the 7680×4320 resolution, but that’s years away from mass market and again, due to viewing distances, of very limited use. At an eight-foot viewing distance, the PPI required to qualify as a Retina display is just 36.25. A 60-inch TV at 1920×1080 hits that target now. This suggests that the benefit of higher resolutions for the average TV/movie buff will be slim indeed.
Right now, the materially higher costs of production and the panel sizes themselves don’t favor much movement on this front. Most software doesn’t scale well to high desktop resolutions, and while Windows 8 introduces better resizing schemes than its predecessors, Metro’s preferred data density hovers somewhere around “cream puff” when compared to Windows 7. As much as we’d love to sail in proclaiming the imminent rise of large, high-resolution displays, it’s highly unlikely.

What can the eagle-eyed do?

If you’re a sharp-eyed reader or work with your displays just off the tip of your nose, your options are rather limited. After hunting through Newegg and across multiple manufacturer websites, we’ve found a handful of 22-inch displays that offer 1920×1080 as a maximum resolution, which nudges them over the 100 PPI mark. The only displays that offer a higher PPI than that are the 27-inch options with 2560×1440 as a default resolution. HP has one for $679, and they move into the mid-$850s thereafter.
30-inch displays with a maximum resolution of 2560×1600 are fairly common, but also far more expensive. These hit the 100 PPI mark alongside the 22-inch displays we already mentioned.
That’s about it. There may be older products that offered higher resolutions, but even the top-end consumer products in the $2500-$3000 range are limited to 2560×1600 at 30 inches. The only displays with a higher PPI are specialized medical products.
It’s possible that technologies like IGZO and OLED could spur manufacturers to offer new, ultra-premium options that combine higher resolutions with new display tech, but we honestly doubt it. It’s far more likely that we’ll see these technologies debut at as close to a mainstream price as they can reach in order to ensure maximum price appeal in an uncertain market. For now, 108 PPI is the highest resolution within reasonable reach.
