you like the Achieva better than the Catleap?

I found a Catleap with glass sceen on ebay.

Would that be as good or better than a glass sceen Achieva.

Or is the Achieva better for other reasons?

I like the slimmer profie of the Catleap bezel, but I wish it was not so glossy...

brucethemoose when you said the Achieva has much better viewing agles and 4x the resolution, I assume you are comparing it to the Samsung TV?

Sorry, I wasn't clear. I was comparing it to the old Samsung TV: with or without glass, the displays of the Catleap and Achieva are essentially identical (as they use the exact same LCD panel). Both are glossy, with the same viewing angles, and it is possible to get an anti glare coating for the glass one.

Has any one tried displaying 1280x720 on their 360/ps3 with the basic Shimian? The HP ZR2740W which lacks an osd+scalar works with consoles at that resolution

no problem, the truth is I get confused easily....

I am leaning towards Catleap w/tempered glass, I was leaning towards the Catleap Multi w/hdmi but now I am a little scard since someone posted an issue about lag. I wonder what kind of lag he was referring too. I guess it was the image response, but I am not sure. If it was the On Screen Menu lag I would not care.

I am reading some posts about the crossover 27q, seems to be the same monitor with a nice looking WHITE case with air vents on the back....

I wonder if I should wait in case the 27q's start showing up on eBay soon.

Any thoughts?

By the way I appreciate BRUCETHEMOOSE answering so may questios, your very kind and helpful - THANKS!

Sent email to ebay seller asking if BFG 7600GT OC will drive the catleap. The 7600GT has 2 Dual Link DVI-I female ports. From the pics, the catleap comes with a dual link Male DVI-D to male DVI-D connector which will physically fit the female DVI-I connector. He replied, but instead of answering my question, asked me to confirm that my card supports DVI-D dual link.

DVI-D and DVI-I should be compatible?
Anything to suggest why it won't work?
Anyone connect a video card with DVI-I to a 2560x1440 monitor and have it work?

I believe its because dvi-d would push the res needed to run the monitor while dvi-i couldn't.....
Quote:
The DVI specification mandates a maximum pixel clock frequency of 165 MHz when running in single-link mode. With a single DVI link, the highest supported standard resolution is 2.75 megapixels (including blanking interval) at 60 Hz refresh. For practical purposes, this allows a maximum screen resolution at 60 Hz of 1,915 × 1,436 pixels (standard 4:3 ratio), 1,854 × 1,483 pixels (5:4 ratio), or 2,098 × 1,311 (widescreen 16:10 ratio).

and with dual dvi-d
Quote:
To support display devices requiring higher video bandwidth, there is provision for a dual DVI link. A dual link doubles the number of TMDS pairs, effectively doubling video bandwidth at a given pixel clock frequency. The DVI specification mandates how the dual link may be used. All display modes that use a pixel clock below 165 MHz, and have at most 24 bits per pixel, are required to use single-link mode. All modes that require more than 24 bits per pixel, and/or 165 MHz pixel clock frequency must use dual-link mode. In modes where each pixel uses 24 bits of color data per pixel or less and dual-link mode is in use, the transmitter stripes pixel data across both links; each sequential video pixel is transmitted on alternate links. In modes with color depth greater than 24 bits per pixel, the second link carries the least significant bits of each pixel.


So yea dvi-i is a single link cable and cant push the resolution nor the refresh rate needed.
Small wonder.

What do the DVI ports on your 7600GT look like? If they look like either of the top 2 DVI ports, you should be good to go. If they are like the others, then I would say no.

At least that's how I read that pic.

For those debating on whether or not to get the tempered glass-- don't. It's a bloody stupid feature. It's a crime, honestly-- everyone wants to get the apple minimalistic look but very few manufacturers do it right. Usually what ends up happening is you ruin the monitors. I mean think about it, you're basically putting something between yourself and the display. That's a crime. Sometimes you end up with reflections appearing on both the glass and the panel and it's infuriating.

Had this problem on my DELL Studio XPS 16. Drove me batty. Though I'll admit, it may be possible to keep it under control on a monitor, with which you can guarantee a glare free environment.
