Why would all display pc monitors in a store be fuzzy and blurry?

Why would all display pc monitors in a store be fuzzy and blurry?

I went to a store the other day (MediaMarkt, Berlin) looking to buy a second pc monitor.

"In most places, the ""wall of monitors"" use a VGA splitter to turn one signal into many. In most cases, these stores buy the cheapest (read worst) video splitter they can find. If they had 30 monitors to display, they may have to daisy chain a number of smaller video splitters in order to get the picture on all of them. Every time you split the signal, there is some degradation. Add to that the above mentioned cable length/quality, non native resolution, and possible interference; and you get a crappy signal.

What I would recommend is that when you want to buy a new monitor, do some research online. Find out the key characteristics like native resolution, dot pitch, response time, and manufacture warranty. I usually use newegg as a good place for reviews. Just make sure to take everything with a grain of salt.

In reality, the most important thing when buying an LCD is knowing the return policy for the store and dead pixel policy for the manufacture. It's normally hidden and may require an e-mail to the support folks, but this can save a lot of irritation later. Here is what you should expect for a manufacture policy. Note that after the first 30 days, you can get up to two dead pixels in certain areas and you have to live with it. That's actually a lot stricter then some other manufactures (comparison here). When it comes to the vendor return policy be sure that you you buy is what you want. Most will return defective items without incident, buy you may have to demonstrate the problem. So be ready for that.

In my experience, quality LCD screens (high native resolution, low response time) perform much better at home then in the store. As with all consumer electronics, the more you know, the better your purchase will ultimately be. Be wary of ""great deals"" and ""sales"", don't buy something because it is cheap. A good LCD can last long past the warranty and the life of the computer it is bought for.

Hope that long, rambling answer helps you out."

"LCDs or CRTs?

Too many driven off of the same signal would do it.
Running them at the wrong / non-native resolution would also do it.

CRTs generated their own interference as well (but not sure when I last saw one for sale).

I've seen examples of both at my local Best Buy... always good for a chuckle. :-) But you're right in that it sure isn't a good way to sell monitors."

"In my experience, 90% of all flat panels in box stores are left at defaults, and are not running in 'native resolution'. This causes them to look crap-tastic.

edit: I would also add that this is the reason I waited so long to adopt flat panels over crts because I hadn't done the research, and thought they all looked bad."

"there might be an issue with the clock/phase values.

check this page out, and if you can do the test.

"The quality is bad on purpose. There are 2 very good reasons for it:

Bad quality looks cheap. You might
not know it, but the average customer
wants a shop like MediaMarkt to look
cheap. They mostly sell overdate
models, so the cheap image is very
important. It's the same reason why
bad colour rendering TL tubes are
still made for ALDI/LIDL stores. They
make stuff look cheap.
If a product looks bad in store,
but looks realative OK to the
other options, customers are
always satisfied when they see the
product back home running. There
is less chance a customer will
return with the product, then when
all quality is perfect on display
in store already."
