Cheap IPS monitors vs. TN
May 6, 2012

I'm in the market for a new monitor. The cheap end of the market for a new monitor.

I've just done a lot of research on IPS vs TN and learned a lot, but still have some questions I can't find the answer to.

Most, if not all, of the cheaper IPS monitors (

Assuming I'm using a colormunki to profile the display, are there any COLOR advantages still to getting an IPS??? I understand that the viewing angle will be better, and the colors may be better out of the box, but I don't care about that since I sit right in front of my computer and will calibrate the monitor.

I went to BestBuy today and compared a cheap LG IPS235v IPS monitor to the other TNs and couldn't see the difference in colors. Am I crazy, or do the only real color advantages in IPS come when you go wide gamut?

The larger the monitor and the closer you sit, the more likely that you will notice the gamma/color shift on the left and right and also top and bottom.

To see the visual difference between IPS and TN tft panels viewing angles go into the TFT Central reviews and open up a window for each of these and scroll to the Viewing Angles section and click on the image there. Then Alt-Tab to flip back and forth and the difference should be obvious.

The are also a number of YouTube videos showing the difference.

I'm not too worried about viewing angles. I'd be content with the viewing angles of some of the TN panels, knowing that I sit directly in front of my monitor.

I've seen the video comparisons between IPS and TN on Youtube that show a big difference in colors. But these comparisons are all using IPS monitors with a wider gamut.

Are you talking about a color shift along the edges of the monitor? Isn't that usually a problem of uneven back-lighting? Is this more prone in TN monitors than IPS?

The color/tones shift tooooo much in the TN models...
With a TN what I see in the center is different from the corners...
Right now I have 3 monitors with different technologies in front of me
and one is a TN, which is used only to show pallets/tools...
Get a TN and you will regret!

The LG IPS235v is OK, see http://www.prad.de/en/monitore/review/2011/review-lg-ips235v-part3.html

...............................

Anyone interested in buying a monitor for photo work check the reviews:
http://www.tftcentral.co.uk/reviews.htm
http://www.prad.de/en/monitore/reviews.html
In the Prad reviews pay attention to:
-The UGRA test (download the PDF)
-The panel brightness distribution
-The gamut coverage
(good place to compare http://www.iccview.de/content/view/3/7/lang,en/ )
-Profile accuracy and the calibration curves, the good ones are in 45ยบ

-The contrast is the least important as any monitor have more contrast than any paper print.

All? I think not. A simple IPS vs TN search brings up a handful of standard sRGB comparisons and one U2410 wide gamut comparison.

The links to the still images I posted for were for two standard sRGB gamut monitors.

Yes, along the outside edges if you sit too close. No, it is not a back light issue. Not relevant.

Laptop screens are pretty much the worst variant of TN panel on the market. Ever notice with a laptop how there is a dark band along the top and bottom of the panel.

What you will also run into with lower cost monitors (i.e. with TN panels) is cheap electronics processing the image before it gets to the panel. On the panel you may find excessive banding in the image.

Most of the current budget IPS monitors use a 6bit + Advanced Frame Rate Control (AFRC) system to simulate an 8bit color depth. It seems to work pretty well, better than the FRC system used in budget TN monitors.

I'm not sure where you are sourcing your costing from but from what I have seen there is little cost difference between a better quality TN monitor and a budget IPS model.

I'm not saying a good TN is unusable, just that for image editing an IPS is better and more enjoyable in the long run.

Thanks for the comments guys!

In this industry you often hear a lot of "this is better than that" without hearing a lot of the "why".

I was looking for key differences an advantages (besides viewing angles) in TN and IPS monitors with the same gamut. Now i've got some good places to start comparing (AFCR vs standard FCR of TN monitors, color shift and unififormity on screen, ect.) That's exactly what I was looking for.

Thanks for the links to the great recources. I've seen tftcentral before and thought it was awesome, but that prad.de is great too.

Have you checked out the cheap korean grey market monitors?

8 bit IPS, glossy, 27", 2560x1440, 310-450 shipped, depending on model and features.

http://www.ebay.com/sch/i.html?_from=R40&_nkw=2560x1440&_sop=15

You can get a squaretrade warranty on them if you like for about 50 bucks.

I own a Yamakasi catleap.

A- grade LG panels - the ones that don't get shipped to Dell and HP.

Monitor lottery for a few dead pixels or slight backlight unevenness. My Yamakasi is near perfect - no dead pixels that I can see after a quick look, and only a slight 1" wide horizontal band of dimness at the bottom of the monitor that shows up only if the brightness level is set at less than 80%.

If you can live with slight imperfections, these are the best deal out there, IMO.

I bought mine when they were 400, but competition has brought prices down. A STEAL at 310+ bucks.
