@Colossos (Colossos) posted a new topic, subject "TFT to replace CRT on our desktops?". It read:

   So, lately the CRT monitors has been dissappearing from our desktops and replaced by the new slim TFT's. A few years ago the TFT monitors was expensive and the performance was bad in comparsion to CRT, but now it seems they are quite equal. I've read that most TFT's does not have the necessary update frequency (8ms) for 3D applications to run smoothly, but what about the ones with 2ms update frequency? Does those 2ms TFT monitors have the equal performance as the CRT monitors when it comes to colors, luminance, resolution, sharpness, update frequency and image loading capacity for 3D applications? Also, since I'm a little ergonomic freak, I've noticed that TFT's does not have TCO'03 certifications, which I think is a small downside. What do you think, can TFT replace the CRT on our desktops when it comes to the requirements of todays 3D applications?

    In my experience LCDs have already replaced CRTs for most 3D work. Displays are fast enough for this for some years now and the few restrictions they have are far surpassed by the advantages. I think it's currently only the people who rely on color proof displays that are still a bit reluctant to change, but even they have a rather wide choice of calibrated LCDs now.  
    Here at MAXON not a single CRT is in use anymore, they were all replaced during the last five years.

    On my desk they have. It's much more comfortable if you are running a dual setup. There's more free space on the desktop and I don't recognized any disadvantage after switching to two Samsung 17" TFTs. The lack of the TCO'03 is not that important for me. And if you take the time to configure your system well there is no difference between a CRT and a TFT. I just imagine the time as I had to calibrate my CRT for hours. So that's something I would also do if necessary for a TFT system.

    One problem with LCD (TFT) displays has been contrast levels.
    
    CRT's have almost infinite contrast control-and LCD manufacturers have been hard at work trying to improve the inherent defecits that LCD panels exhibit in this area.
    
    It's hard to get both a nice deep black and still be able to see subtle changes in increasingly luminant regions of the same image. It's mostly either-or.
    
    At Siggraph, I did see some new LCD technoloogy prototypes that claimed better than 10,000:1 contrast ratios and full support for HDR imagery.
    
    I caught myself literally drooling on my shirt. It looked SOOOO good.
    
    Unfortunately, it sounds like we are still a couple of years away from accessible (read inexpensive) LCD technology that is as “good” (in terms of contrast and color saturation) as the best CRT displays were.

    Yes, HDR LCDs are realy mouthwatering. I'm holding off replacing my big old Sony Wega 100Hz TV with a LCD until i can afford one of those HDR LCDs

    Hey guys while you are here… I have a Boxx and an older CRT from Dell. There are times when I turn the computer on and the monitor wont power up. I called Boxx support and they told me it was a usb port power problem… that the monitor was drawing too much power.
    
    One, how can I fix this?  
    Two, I may be getting a new monitor, can you recommend one?

After which, @aglick (aglick) added

    Hi Dennis,
    
    I'm not sure…
    
    Did they give you a work-around or a fix? I'm not really up on all that stuff. That's a totally different department…
    
    Did they offer any suggestions as to a work-around or a fix? If not, you should call them back and ask them for one… I know we do not like to leave issues unresolved…in fact it's against our policy.
    
    As far as a new monitor, If I were you I would use these forums to research this for yourself. There is an amazingly rich database of user experience here… I look to these forums every day in my research and quest to gather the knowledge I need.

    oh, I just re-read your post and noticed that the monitor is a Dell…
    
    Man, good luck with that.

    How is the Display connected to the computer? How many devices and which are connceted via USB? An USWB hub can help, because active hubs are providing an independent power source. Most USB hubs in computers are limited to 500 milliamps. So if you'r PC has 4 internal hubs and you use all they draw 2 amps from the 5V source. But I think that wouldn't affect the 12V source for the CPU.

Then @raycerx (raycerx) said

    Thanks CConcepts, The monitor is a pin conection only to the back of the computer. I have a Wacom tablet, keyboard, mouse, and thats about it. You are right. I talked with Boxx suport and they are aware of the problem and are trying to get some resolution. They say that the culprit is the Tablet drawing too much power. The only cure at the moment is a self powered usb hub. Not perfect answer to the problem but I am happy that there is a rather simple solution.
    
    Thanks again.

    Thank you for the information regarding CRT and TFT displays, I'm convinced about my next buy, and I will replace my CRT to a new TFT.
