    Image is blocked, (I'm at work) I will check it out tonight.

    My OQO device's native resolution on it's internal screen is 800x480. I can then plug in an external monitor and set that same resolution on it in Windows. When I do so I get Xenarc OSD saying 640x480 while Windows says 800x480. The Xenarc screen IS showing the proper proportion and positioning as 800x480 but the image looks stretched and distorted. This is one of the reasons why I think the Xenarc takes a widescreen image, converts it to the nearest 4:3 resolution, then stretches it into it's display at 800x480. What we have is:

    PC signal 800x480 ---> Xenarc stage 1 scaler converts it to 640x480 (nearest 4:3 resolution) --> Xenarc stage 2 scaler converts it back to 800x480 (causing distortion)

    It's still tough to accept that there's so much trouble getting this $300 unit to display properly and the Xenarc guys are encouraging customers to hack and experiment until they get it right.

    I did notice that no Xenarc products are on the Windows Hardware Compatibility List (HCL) which is not a surprise. I'd imagine if Xenarc submitted their product for review it would fail. Bottom line is when you set 800x480 in Windows, the monitor should display properly regardless of anything, and it does not. The HCL is our friend.

    Xenarc support

    Here's one of the responses I got:

    "800x480 is not a normally supported resolution by most graphic cards. It is NOT a resolution in the VESA standard. Accusing us of not providing a list of compatible adaptors and or not providing enough information to support native resolution is like saying companies like Panasonic, Samsung, Philips, LG are doing a poor job by not providing a list of compatible adaptors and enough information to support the 1366x768 native resolution of a lot of their plasma TVs. Such info was never provided just because it’s not a STANDARD resolution. However, I understand your frustration.

    Our monitors are designed for standard resolutions such as 640x480, 800x600, and 1024x768. That is why our monitors have a built in scaler. The truth is, the majority of our customers use the standard resolutions. Now let’s get to 800x480. Some graphic cards support 800x480 from the factory and powerstrip IS NOT required. You can just set the included driver to 800x480. The reason we suggested Powerstrip is because it is the most widely used software by people who owns a graphic card where the driver doesn’t have an option for 800x480 but the card itself can display in that mode. In your situation, it is simply the fact that OQO DOES NOT support 800x480. It should be the customer’s responsibility to make sure that their graphic card supports a non-standard resolution, not ours.

    The 705TSV does support displaying 800x480 and I have played around with it many times with an ATI Radeon 9550 video card. But what I can tell you is that the 705TSV uses a chipset inferior to that of the 700TSV. Thus, the cheaper price. So at native resolution, the 705TSV is not crystal clear like the 700TSV. It is because the chipset it uses doesn’t send the signal dot to dot. However, the display is still sized properly at 800x480. My suggestion for you for “maximum clarity” is:

    1. Get a graphic card which supports 800x480. I would recommend ATI Radeon series
    2. Exchange your 705TSV for a 700TSV

    And again, Powerstrips is OPTIONAL. Many video cards such as the ATI Radeon comes from the factory with support for 800x480."

    very professional response, still not sure who to blame.

    I guess ill keep using the 800x600 (picture was really crisp, only using 800x480 gave me weird/poor result)

    whats your plan ?

    Well, meanwhile back at the OQO (after Jimmy said it doesn't support 800x480):



    Here's what it looks like on the Xenarc:



    The OSD gives me 640x480, you can see the font distortion there. I can't tell from your photo but are you getting the same font distortion?

    Anyway my plan is to keep it as a reminder to do better research before I buy crap. I will see it in my car every day. It will probably be just fine since I only plan to use it for the media player software I built (specifically for 800x480), which looks "acceptable" on the screen but not spectacular:

    yes, font are crisper in 800x600 than 800x480

    your skin look OK to me, i believe this drawback is worth the $100 price drop compared to 700tsv
    but thats just me :-)

    I start my 705tsv review once i have it in the car for at least 2 weeks: http://www.mp3car.com/vbulletin/lcd-...view-pics.html

    Anyway another Jimmy response:

    "I have tried my best to help you to achieve something that is “uncommonly used.” There is nothing further I can do if you are still not satisfied. The truth is clearly that our monitor is working as advertised, just like how most major brands advertise their TVs. And the truth is, you are unhappy just because your video card cannot support 800x480. Many other customers are happy using our monitors at 800x480 as well as other common resolutions. Go ahead and let other people be the judge whether it’s we are at fault or you are just being ignorant."

    For me, if I'd have known it wouldn't be dot-for-dot 800x480 I'd have never bought it. There was nothing available in the product description or anything else that would have told me that before purchase.

    fair enough, i contacted the shop i bought the screen from because the guys said he was using the 705tsv in his car, will see if he got it working

    I doubt it (will post his response)

    quoted is Jimmy response to my emails (very professional ):

    Hi Mathieu,

    The picture was taken at an angle. But when compared to what you sent me it looks like full screen without distortion. 800x480 is not a VESA standard resolution and it is not a resolution that is on the HCL (Windows Compatibility List). That’s why it might take a little experiment to get to. The internal chipset of the 705 was built upon standard resolutions such as 640x480, 800x600, and 1024x768. We built the 705 because it was a lower end model. But unlike the competitors’ monitors, the 705series excels in standard resolutions in turns of picture quality and life span. It has picture qualities that no others can match at the same price level. Plus it has a LED backlight system that lasts longer than conventional monitors and provides maximum brightness upon Power-ON due to its LED backlight. Our tested and proven 700 series utilizes Pixelwork chipset that has far superior video quality than the 705 and other monitors when it comes to 800x480 and other common resolutions. If you are not satisfied with what you have achieved with the 705 series, we would be more than happy to exchange your 705 for the 700series for a minimal fee.

    Regards,
    that explain the stretching problem, as i said, 800x600 might work fine for me, will see after 2 weeks usage

    sounds like the 705 chipset is similar to that of the lilliputs. i purchased a mp3car transflective recently which is an upgraded lilliput. i tried everything to get 800x480 to display correctly on that monitor. in the end i had to replace the lilliput controller with the xenarc 700 series controller to get what i was after. it looks like xenarc has put out a product in an attempt compete with the cheaper lilliputs which are so popular here.

    it is very disheartening when an lcd with a native resolution of 800x480 will not display 800x480 correctly. it should be a requirement that any chipset developed for a lcd controller must support the lcd's native resolution.
